Flywheel stripped

Post by gsim » Thu Aug 22, 2019 8:06 pm

I've got a problem, went to pull the flywheel in my Gaucho and the threads and stripped. I can get bolts to go in but there really isn't anything there too grab. Any ideas on how to remove it. On a side note the crankshaft is bad so I need to replace it. I'm up for ideas on this one. Thanks y'all.

I used a three-jaw puller putting the legs of the puller through the large rounds holes in the flywheel.

You dont actually pull of the flywheel with the puller. Put the puller on and turn it in and put pressure on the flywheel. Now smack the flywheel with a hammer. It should pop off.

Is there a sweet spot for the hammering on the flywheel? Heat help with the process? It looks like there is the same type of thread material around the crankshaft that was in the the clutch screws. I'll try the 3 jaw puller tomorrow.

Shouldnt need heat, but it will help if you want to use it. I usually smack it around the outside edge of the flywheel.

I prefer to strike directly on the end of the puller pressure screw, they're made to hit there and less chance of damaging the engine case or flywheel. It shouldn't take a lot of force from the puller.

Happy trails,

Three-jaw puller and hammer 🔨 tapping for the win. Thanks for the help. The jar puller is definitely tricky to get in there though.

You could always tap out the holes to the next UNC or UNF size, whichever is closest to the original thread.

That's the plan now that it's off.

Might be worth keeping the threads metric. A heli-coil could be a good permanent fix. It would be really easy to do well with the flywheel off.

Best,
