Flywheel problems

[Stephanie]

So, B_Hix (Brad) was an amazing friend and stopped by today with his cherry picker to help us get our engines out of Chester He stayed and assisted us for a few hours, but we learned quickly that our engine is going to be very very VERY difficult.

I need your help! Would someone please tell me how to remove these bolts from the flywheel??



We are at a loss! We have tried for over two hours to try and get them off. We have tried letting them sit in lubricant and nothing will budge. Even tried banging the wrench with a mallet to try and jar them loose, but nothing! It is the very last thing standing between us and being able to reach the bolts to get the bellhousing free so we can FINALLY attach our engine to the engine stand. I am hoping and praying that someone on the forum has the answer or can point me in the right direction.

Thank you all in advance!

Hi Stephanie, assuming you haven't tried this already but the easiest way is to use an air impact rattle gun "well thats what we call them here in Australia" only use a impact hex socket to prevent anymore damage to the bolts. Hope this helps, George.

An impact would be nice but a long handled handled 1/2 inch flex bar and a six point socket should work. You might need a cheater pipe to break them loose. Remember they unscrew counter clockwise.

If the flywheel turns when you try to take them loose and it should put a stick of wood between the flywheel teeth and the right side of the bellhousing to hold it from turning.
I've also screwed a long bolt into one of the pressure plate bolt holes so it would catch on the edge of the bellhousing and hold it.

Hi Stephanie - any luck? Can bring over a breaker bar, etc if need be...

^^ Was great meeting Stephanie and her husband - they've got a really cool project going!

impact, air or electric would remove them.

In the Picture the locking tabs haven't been pushed down. You did do that right? Just checking sometimes the little things can be overlooked. Great project you have going. Best of luck.

It helps to grind the surface of the 6 point socket down a little. They are tappered on the end so you will get a better grip if it is flat.

Heat it with torch or propane until they are red, spray penetrating oil then remove with impact wrench.

I've never had to do that on a flywheel bolt. I'm thinking they just don't have enough handle on the ratchet they are using to break loose 80lbs and maybe more torque on the bolts.

That or the engine is turning when they are trying to break the bolts loose.

What he said. I keep a 4 ft metal pole for this reason. Slide it over the handle to the 1/2" drive breaker bar (I've used wratchets before and you can end up snapping their gears, but yay Craftsman warranty). When you hear the snap you'll think the breaker bar broke, but it's just the bolt popping loose.

I lucked out years ago when my father in law gave me a 3/4 drive breaker bar that is about 28 inches long. I have a 4 ft cheater pipe that slides over the end of it though.

You all are so wonderful! The tips and advice was absolutely perfect! B_Hix let us borrow his breaker bar and we were able to pop the bolts free after jamming a screwdriver against the flywheel and the oil pan to stop the engine from turning as we bared down on those bolts. Great jerry-rigging there :P After a few wakes with a mallet, it popped right off onto my finger :P Haha! Walked away with only a bit of a swell which was nice, but that flywheel just had to have one last go at us.

Thank you all again for all the tips and advice I love this forum because of all these response right here
