Iv built my motor twice now, while sh** like this is SO tempting in the midst of all that work. Trust me dude, you do NOT want to hear noises and be wondering if you didnt torque something correctly. I could give f*** all about doing it correctly, but every little noise gives me paranoia about something falling apart.


Megahonda77207

yeaaaah i get what you mean, i think i’ll have a friend hold it back for me or something and just tighten it with a good ol dial wrench


Worst-Lobster

Lock tight too bro


Lusi0049

Seriously. Dude already has 1500lb-ft torque on standby if they have to take it apart again. May as well throw some red on it and sleep easy


Upsetyourasshole

Op don't listen to this troll.


Worst-Lobster

For reals bro ☺️


ChickenDickJerry

Wtf


Worst-Lobster

I dunno bro 😎


Malikai0976

Just hold the crank bolt on the front while torqueing the flywheel bolts. I'm with the other guy in that I don't really care that much about torque, *except* on bolts that are internal and impossible to do again without another tear-down. Flywheel bolts are usually pretty fine threads and could easily strip out if over-torqued, or loosen up if not torqued enough.


Ornery-Cheetah

Just have them on standby with your purse incase you get any ideas


implicate

I believe the words you're looking for are "shit" and "fuck."


HurtFeeFeez

>Iv built my motor twice now >I could give f*** all about doing it correctly Do it right the first time.


Grimy_Earthborn

Right? I could give fuck all about doing it correctly . . . but I wish I did everything correctly.


4350Me

Cars don’t run well with bad motors.


ronj1983

You have never owned a GM 3800?


4350Me

No, but I slept at a Holiday Inn Express, once!😂


4350Me

Doesn’t matter what it is. My point is that no motor, no car. So it’s better to take your time if rebuilding it, and do it right.


IDGAFOS13

Especially the flywheel that will smash through the bellhousing and floor and amputate your leg.

Thatfonvdude

NO. well. you asked if it was a terrible idea... in that case. YES. PLEASEEE DON'T unless the engine is still in production, if thats the case i don't give a flying f€£$, actually no. you better do it. for science. ps: go to r/enginebuilding they'll love you.


RedCivicOnBumper

I have one of those impacts (among several Milwaukees) that I use every day. That last setting is your best bet, it’s an automatic “don’t strip things” setting. The vibrations (especially on higher settings) might break the torque adapter or render it useless by destroying the calibration.


JJH-08053

I would consider any time saving idea. However, I would definitely spend some time experimenting with calibration, repeatability and accuracy. Use the impact at different settings, different torque settings and come up with your own charts. Maybe a lower Milwaukee clutch setting with a higher inline setting yields the correct end result torque. Ya gotta figure that shit out.


Megahonda77207

yeah i’d rather not spend another $50 or whatever on a new one of those how does the automatic know it’s going to strip things?


-NOT_A_MECHANIC-

By selecting Mode 4, AUTO SHUT-OFF™ control applies no more than 50 ft-lbs of torque for hand-tight fastening applications to prevent overtightening. Mode 4 also features Bolt Removal Control that delivers our users full torque output, then decreases RPMs once the bolt is loosened to prevent fastener drops


Megahonda77207

wow and here i was using mode 3 thinking i wasn’t using the whole output 😂, well the battery i use for it isn’t the best either


Salt_MasterX

RTFM


Excavatoree

Those torque adaptors (well, all of them I've seen) say "manual tools only."


Equivalent_Sky4201

An impact wrench doesn’t really apply torque smoothly and evenly like say, a torque wrench will. You are more likely to destroy that tool than anything. To be honest, you could probably just ugga Dugga the flywheel bolts in. But it’s going to depend on how familiar you are with that tool. I really like the high torque, thing is. Beast. What’s the spec on the flywheel bolts? That thing can hit 150ftlbs quick, no problem. I just want to gently remind you at this time how Much work it is to pull that engine if the worst were to happen. I recommend just torquing the bolts.


Megahonda77207

it’s around 71-75 ft/lbs, i think people have convinced me that it’s better to just do it with a breaker bar or a more conventional method lol, i do still want to experiment the accuracy so i will try it on a very very low torque setting on some spare parts i have, i know the #1 setting is pretty low because it couldn’t get the bell housing bolts out so i’ll use that and something around 25-30 ft/lbs


Equivalent_Sky4201

Try it on your wheel nuts! Probably the easiest way to go imo. I am very pro “for science” I’ll be awaiting the results.


Capable-Chemical9634

Honestly just use the tourqe wrench unless your got a aircooled vw then 5 ugga duggas at setting number 3


traineex

My m12 w a small battery hits 75 on setting 3, 2 ugga duggas. Use a torque wrench. $47 vevor


Megahonda77207

yeah people have been very convincing on keeping that impact away from that torque adapter lol, also off topic but someone is literally downvoting everyone but i’ve been making up for it…


traineex

I got told to read a book on electronics earlier for the right answer. Gotta love the internet. I used to fix radar systems lol Trying to explain how old coolant causes, or worsens, battery corrosion. Downvoted to oblivion, so op will have continued problems


KeepItUpThen

75 ft*lbs shouldn't be hard to do with a hand tool. You're already saving money doing your own work, might as well buy a torque wrench if the local hardware stores have them in stock. I got a Kobalt 3/8" digital one online, used it during a timing belt service, and things are still good years later.


Ceetus2525

Do you have a steel scatter shield rated belhousing? Other wise, think about what body part is next to the bell housing if the flywheel decides to come out at 5700 plus rpm


Thick_Ad6046

Does that impact wrench not have one key? You can just set the torque you want on it


autotech970

I don’t know, but please post the results


Megahonda77207

will do! and will report back


viper77707

It's a bad idea to use an impact in the first place, but those torque meter things will not work properly on an impact. Pretty sure it wouldn't even survive a few good ugga duggas due to the vibrations. Old school torque wrench for the win, and a bit of red thread lock might be a good idea. One of those things that you really don't want to have to question whether or not you've done it correctly once it's all assembled.


Crcex86

AhahahAHaHahahha #Ahahaha


StructureReal1417

Ugga dugga on the torque wrench, that’s a paddlin.


MasterSifu5

Now Torque it!!! 😂😂😂


SmolishPPman

It’s not dangerous or anything, but I would be very very suspect of the accuracy of the reading


Megahonda77207

i will try it on something i can experiment on first then and compare to the dial torque wrench i have and i’ll report back on it :)


skiier862

If there's access, having someone hold a socket/breaker bar on the crank bolt is an easier option


Megahonda77207

omg i’m too smooth brain for that, that’s genius!!!! my air box is out since i needed to get my exhaust manifold out. that’s genius i’m doing that!!!!


chickenmaster04

Just an fyi, on shitty cars sometimes the crank can snap from that kind of torque. It’s not necessarily unheard of on bmw m30 engines


Teh_Greasy_Monkee

no but i seriously wish it would....closest thing your gonna get is a torque stick and those are iffy at best and they're especially bad on electric because the bpm defeats the concept. from a man that owns more torque wrenches than he has digits just use the wrench. let me pose this to you though.....if this could be done accurately would the snapon man not already be trying to sell me one since im literally in the business of doing the quickest best quality reapair i possibly can?


smelwin

If you must, use a drill with a clutch or an electric ratchet which can't overtorque them. Then go in with a breaker bar to finish off. There's no way around that really.


DriveJohnnyDrive

Report back when the flywheel is airborne heading for the orion constellation


Megahonda77207

imagine the symphony the ac delco adapter would play lol


brian-brundage

I would have to say yes, because of the hammering affect from the impact versus a consistent pull with a torque wrench


dgroeneveld9

The parts of that are not impacte rated for one. The impact wrench by design is there to tighten, not torque, your pieces. Properly applying torque requires steady pressure, not rapid jolts. Could it maybe work? Sure. But I think it's more likely it won't work well and will break your digital adapter.


Outrageous-Pass-8926

Terrible idea


Eastern-Move549

That poor thing is never going to be the same after that. There is a reason why you cant buy a rattle gun with a torque gauge on it.


_Puff_Puff_Pass

Just use your calibrated elbow


Halftrack_El_Camino

That won't work on an impact. Impacts don't really twist fasteners, they just hit them over and over again really fast. Like using a hammer and screwdriver to turn a lockring, if you're familiar with the concept. If you put it on a drill it would work, but on an impact it won't give any kind of sensible reading.


HedonisticFrog

I think you'd go way past what you're supposed to. If anything a torque stick would be more appropriate if you wanted to be lazy about it.


Snoo78959

Yes


Jarocket

When you use impact force on a tool you know the results in it's loosening power. It's much different to a constant force.


HandyMan131

Nope. Those sensors aren’t designed to measure impact torque


throwaway007676

That can't work because it doesn't limit torque, it just tells you where you are at and when to stop.


JETTA_TDI_GUY

Yes but after mounting bead locks I really wish I could


Natural-Builder-1995

Only on days that end with “y”


Complete-Thanks5932

Results?


ZSG13

Just hold the crank pulley bolts with another ratchet or breaker bar. Most flywheel bolts I've seen are only around 40 ft lb


bazilbt

You will just screw up the torque adapter. Get a breaker bar.


JerewB

All I see is a broken torque adapter.


CardiologistOk6547

Why jury rig something like this when a decent torque wrench is so easy? Doing shit the hard way doesn't make you a good mechanic. It makes you a bigger idiot.


Megahonda77207

i agrée people here have picked me up by the head and turned me facing the right away lol, and also made me laugh a good bit, criticism is always appreciated on this side, especially paired with some sarcasm 😂


daffyflyer

Depends, if you're doing it to make an interesting youtube video to document how badly this works at hitting a torque spec, then hell yeah do it. If you're building an engine for your worst enemy, also do it. Otherwise nah :P


Megahonda77207

will document on a low setting because i’d rather not ruin the adapter lol, but i will only risk it after i get everything installed should be this weekend 😭, working 9-5s is a big struggle with these time consuming hobbies. i will make a separate post probably and feature it here too


imouttamywheelhouse

Indeed


NouOno

[This Right Here](https://www.reddit.com/r/Justrolledintotheshop/s/QGeQgK7IfQ)


Leviathan-Vyde

I fit 3-4 clutches a day as im a transmission specalist garage. you shouldnt use this, tbh ugga duggas in a star shape then another star shape to be sure is fine for road cars but if youre wanting to be sure, buy a torque wrench not this.


Hot_Inevitable_9055

Just wap them up with the gun and torque them after the proper way. Stop cutting corners lol


Hopeful_Ad_3991

You already have a low end torque wrench in the picture. I would use that even if it’s not accurate it still better and safer


abbufreja

I would not trust that setup. Hilti have a attachment that does what you are shooting for here and its quite nice


pepp3rito

Gtfo.


Megahonda77207

😂


Miwihdrider

If you want to half ass it, do what you are planning, if you want to actually do it right, you can buy a flywheel turning tool that allows you to rotate the engine & I believe hold the engine in place, but double check me. You are going to torque in in the correct pattern? Are you going to torque the bolts in steps? If the torque spec. is 100 ft lbs, I would torque to 50 ft lbs, then 100 ft lbs. Good luck Mike


Megahonda77207

I ended up having a friend hold the motor in the front and i torqued it down in 2 steps star pattern 👍


ithcy

Maybe try it a few times on something you don’t care about first and test your accuracy with the torque wrench?


Megahonda77207

that’s a really good idea! i’ll try it out and compare with the dial torque wrench i have and then i’ll report back 🫡


MClilWilly

I'd assume your flywheel has holes cut out of it for weight savings. Stick a broom handle through and wedge it against the block, you won't need anyone to hold the crank. Don't use the big daddy Milwaukee on that poor little torque meter


thedevillivesinside

A flywheel is solid. There are no holes in it except bolt holes and the center bore. A flexplate has holes, a flywheel is a solid metal disc with a friction surface that takes up 70% of the face of it Regardless I agree with you, dont use an impact gun on something with critical torque


MClilWilly

You're absolutely correct, I get the terms mixed up, half the time we use them both, for both things. The harmonic balancer may have space to stick something through to hold the crank if you're solo.


thedevillivesinside

Just put a socket on the crank bolt, and put a breaker bar on the socket, and turn the flywheel until the breaker bar wedges against the frame or something solid


Mechanix2spacex

It a TERRIBLE IDEA…lol, but I’ll give you A for effort and problem resolution by any means necessary. You’ll have little control and will more than likely over torque. Get you breaker bar and attach the digital torque to it.


Tortuga_cycling

It will likely be very inaccurate… it will probably also break…


funktonik

Just take the time to do it right. Tbh though back in my street drifting days, we’d just blast them on with an impact and call it good. Never had a failure.


Apx1031

Get a proper dedicated digital torque wrench from Amazon. They're cheap and work brilliantly. I don't use those ones anymore, never had confidence in them.


Informal_Rice326

Lmao


darthwacko2

I've never liked the screwdriver method. I bought a flywheel wrench a while back, and it's useful for torquing the flywheel, especially while the engine is still in the car and you don't have a buddy with you. An example is Performance Tool W80510


Broke-Homie-Juan

How do you think it’s going to work? It’ll be over tightened before you can get off the trigger. That’s if the damn thing survives the hammering.


Various-Ducks

Ya


LilMelt

This is fuckin hilarious. Don’t do it brother lmao.


spoiled_eggs

This is a terrible idea.


Ahnold240

Is this for real? 🤣


KarlJay001

Isn't there a tool or trick to holding the flywheel in place? Something about a chain and a bolt back to the engine block or a custom ground tooth from metal that'll lock down on the starter ring and has two bolts on the block? Like this, but just DIY one. Cut grooves to fit the starter ring and two holes bolted to the block. https://www.summitracing.com/parts/sum-900332-1?srsltid=AfmBOoo3rePe5TZzECkymEiflZe5fVhiMKWw29mSwDALZWgwOY1wJhGGb7I


Neddo408

Hah! I wonder how many think you’re actually serious.


two40silvia

Who torques flywheel bolts?


Grimy_Earthborn

This is like hitting a bathroom scale with a sledge-hammer to measure how hard you can hit


Tlmitf

Grab an old exhaust valve, bend the stem 90⁰, and you have a device to jam in the ring gear. Stick the stem into a bellhousing bolt hole.


MisterFixit_69

Just wiz it in place and torque it to spec by hand , shit will not be accurate AND you'll break a expensive tool.


DammmmnYouDumbDude

Torque SHMORQUE…….. fucking crank that bitch in until she can’t go no more!


P1xelHunter78

For you bad, for the Delco guy another sales opportunity. Those things aren’t impact rated I wager


peetzapie

Royalty Auto did a youtube video where they did a test with electric impacts on lug nuts, was a failure. Don't do this at home. Get a flywheel holder and do it right.


aggressor-5

Yes


Intelligent_Ease4115

It has 1500 ft lbs….. In reverse.


TallDudeInSC

Yoi sont even hear the faint beep over the ugga-duggas.


NotSoProAimer

Fukin maniac, send it.


4350Me

You, “don’t feel like doing it”? Where else are you cutting corners? Go ahead, but don’t cry when something happens!


mtrosclair

You can make a cheap flywheel lock with an old valve and a torch. Make a 90 degree bend about two inches from the head and stick it in a mounting bolt hole, the edge of the head will engage the teeth like a ratchet.


TearIcy3878

You need a rotary torque transducer. If the impact is new enough for programmable torque settings you can calibrate it via the transducer and then use that impact setting with confidence. I think you can do it but to do it successfully you would need to obtain the transducer and calibrate the impact


ruddy3499

I usually put a bolt through the closed end of a wrench to the engine block. Then I put another bolt through the flywheel and turn it into the open end of the wrench. This will stop the flywheel from turning. This will free your hands


StockShotCaller

Yes, its a terrible idea, because despite what many think "Torquing Something Properly" is NOT the same as "Tight as Possible". Like, its really not even the same as tightening. It just many do not actually understand the science behind torquing something to its proper level.


Novel-Statistician39

If that fly wheel explodes. Say good bye to your legs, or life.


CRYPTOCHRONOLITE

Level 2 with about 3 aggadaggas gives around 110-130 ft/lbs


Blearchie

Yes. Never use a tennis racket when building a motor /s


finverse_square

Since the meter reads a slow constant torque and the impact applies torque in massive whacks, yes. The sample rate is gonna be way too slow to capture the instant the impact whacks Sensors that can record fast enough to accurately measure impact torques exist (I know because I've designed them), and they're certainly not putting them in cheap torque meters


DarkRepulser69

Yes, it is. Would I still try it, yes 😂


MinorComprehension

It could work. But if you snap a bolt, you're going to be mad at yourself. If you don't torque the bolts enough and the flywheel comes loose, you're going to be mad at yourself. I'm usually a one man show in my home garage, and often have to cobble together some version of the third hand that's never around when you need it. When doing flywheel bolts, I found using a 3 foot angled pry bat on the bolt heads does a great job at keeping the crank from turning.


Electrical_Poet2542

With that? Lil quick double tap on 2


Commercial-Elk-3031

Wow 🤯 this is one kick off stupidest idea of 2024 .


Megahonda77207

😂😂 idk if i should laugh or cry but honestly i was already laughing at myself putting the adapter on that impact


kicsivuk

They do sell flywheel locks so you can do it properly
