M60 Jesus bolt, im getting desparate

[dasmanschaft012]

I am trying to get the crank bolt off of my M60, and its just not budging. Killed 2 breaker bars, tried a 700ft-lb impact, tried 10ft pipes tried heating it up tried drilling the head out. its just not budging and im starting to think this crank is gonna be scrap if i cant get it out. Open to ideas. I'm currently looking to see if anyone has a 1000ftlb or greater impact. I just wanted to get the lower timing cover off to do seals and guides, but Im starting to think that I need to be looking for another crank now for a rebuild :( thanks.

The M18 Fuel 1/2 Impact does up to 1200 ft/lb
Their claims seem realistic. May be time to buy a new tool!

Time to get an air gun

My air gun is 700ft lbs and it's not moving it.

Or a bigger air feed to the gun. 3/4" air line will get you more CFM to the gun which will give you more torques!!

Is the motor in or out of the car?

Remember that the crank bolt is reverse threaded so you have to turn it clockwise to loosen it.

Worst case load up the engine and take it to a big rig truck shop.

dont say that

just needs 3/4" drive heavy duty stuff and a thick walled pipe

Everyone keeps saying this. It's not. I have the replacement bolt in front of me, its regular right hand thread.

I couldnt get the main nut off the back of my gearbox and id tried all the diy things. I ended up taking it to a truck driveline machine shop. They had the biggest rattle gun ive seen and it came off in 2 seconds.

Dont go incremental, get an inch impact wrench and apply all 2000 ft/lb of it.

Otherwise get a ladder and inch breaker bar and a 30 ft cheater bar.

Update: Got that f***er out. Torched it for 15 min, got the crank holder to press on the ground, and then jumped on the end of a 10ft pipe on a 3/4" breaker bar. Unthreaded by hand after the initial CRAK. thanks guys. Now to replace the chain and guides.
