Flywheel removal - tricks & tips?

lhfarm · Sep 13, 2013

Not a tractor, but one of my farm jeep engines. An L134 to be exact. From what I've read on the jeep forums, I should be able to put a couple of pry bars behind the flywheel and it should pop. No luck with that. Been treating it with PB Blaster and whacking on it with a wood block and with a rubber mallet. I'm tired of playing Whack-A-Flywheel.

I've looked on line for a flywheel puller, but haven't found any. Haven't seen any homemade pullers for anything larger than a motorcycle. Would love to hear your ideas.

Thanks,

Post a picture, maybe the creative juices of this very knowledgeable forum will come up with good ideas.

A quick picture. This engine has been sitting on a stand for years. It is lightly rusted and needs a pilot bushing (one reason for removing it. The "dots" are the thread holes for the clutch housing.

The bolts/nuts have been removed. If you need a better shot, let me know. The flywheel is about 12" across.

Thanks,

I'd say minimum 4 lb. sledge, and like oak 2 X 4 long enough to hang on to. Hit on the outter edges out towards the ring gear back & forth. It may rock it off the end of the crankshaft. A couple of studs in enough to hold it just in case it pops loose..!!

And as Pap used to say... " If you're going to hit it... HIT IT..!!"

Are there 2 studs with nuts across from each other,and the rest are bolts? I was looking on www,kaiserwillys.com and there should be 2 tapered dowel pins with nuts,that line it up.They slip in from the back,but you have to drop the crank down to replace them.Might try a brass drift on those 2 studs to knock them loose? Or block of oak and hammer?

Try striking the flat area where you removed the retention bolts with a large flat face hammer. Sounds like the flywheel is rust welded to the crank. Careful about beating on the outer edge. The starter ring can break loose and come off or be damaged.

pilot bearing removal ( without inside jaw puller) find a big bolt with the same diameter as the center hole of the pilot bearing ... ( or wooden dowel ) .. pack the center of the bearing with old grease ... work most of the air out ... put the bolt/dowel in the center hole and whack with a hammer ( poor man's hydraulics) the pressure of the grease behind the bearing should pop it out...

to loosen the flywheel... put a piece of hard wood / alum/ brass on the teeth of the flywheel, hold it angled to the flywheel , whack the wood end.. (trying to turn the flywheel in one direction then the other) it should start to slip after a few hits ... once it's loose, pull on both sides ( 180 apart ) and rotate it CW and CCW till it wiggles off.
