thanks aviatior...

 

Or this with a small torque wrench, because you WILL need to get your car on a lift to use the 3/4" drive one with the 3.5 foot reach!

 

I've always gotten a 2 ft breaker bar and stood on the end. (At 170 lbs, I'd be putting 320 Ft/Lbs of pressure on the nut.) calculate for weight.

Or just use the impact and trust the max torque rating on it.

I really don't think the flywheel nut torque is critical enough to be dead on.

Tension bolts, water pump bolts, yes.. but that one big one at that high of a rating, not so much.

 

Yeah, I've used my gun and always broke them loose. If it doesn't work with air, then man up.

 

yeah, I just used my weight and stood on the factory mazda tool for removing it at the correct location.

 

Torque wrenches are used for installation, not removal.

 

yea im trying to TQ my flywheel bolt...


I had rebuilt my engine and i used my GUn to the max setting and i was almost to mutch for it, my snap on gun has about 480ft-lb power, im tring to put it back on around 350 ft-lb dead on...

 

I know, but others were discussing removal for some reason.

Torque ratings on impacts are sketchy. I'd say that if your Snap-on gun has 480 max torque, then put it on max and hammer on it for a few seconds. I've seen guns with a claimed 250 ft-lbs that couldn't bust a lug nut loose. My impact has 850 ft-lbs of torque (claimed) but whether it'll actually do that is up for question.

 

 

Yup yup..
