Stuck flywheel

[Travisferrell27]

1998 Evinrude 225 flywheel is stuck I have tried for days with no results took to local boat shop where they ripped thread out trying to remove it brought it back home popped the starter ring off so I could get a 3 jaw puller on the outside of it and still this thing will not move I have tried heat to with no results any help would me much appreciated

Need a model #. Stop using the 3 jaw.puller before you break something.

Can you tap the stripped holes -- or better yet, get the shop to do it? Whatever puller used, takes sustained pressure -- tighten and let it set, then repeat. If you leave it overnight, may find the flywheel popped in the morning. (Leave the flywheel nut installed a few turns to protect the shaft and to keep the flywheel from completely popping off.)

Might want to find out if this is a looper or a crossflow motor first.

Perhaps some clown put Locktite on the tapers.

 

[Travisferrell27]

It is a looper I’ve tried leaving it with the puller on for about three days nonlick

 

[oldboat1]

You're whacking downward on the puller bolt with a couple of good licks, then tightening some more, then repeat?

 

[Travisferrell27]

Yes I was

 

[Travisferrell27]

I’m going to try and retap holes tomorrow

 

[oldboat1]

Due for some success....

When you're whacking down on the puller bolt put a pry bar between the top of the block and underneath the flywheel and pry up on the flywheel.

You should heli-coil the threads to keep them the original size. Plus a heli-coil is stronger than the original thread. You should take it back to the dealer who screwed up the threads and let them heil-coil them.

Update retapped holes airgun a big hammer and lots f heat and it finally came off it was rusted on

 

[racerone]

Not rusted on.-------When the nut is torked too much the flywheel taper is expanded / stretched and really grips on the taper of the crank.----Takes a small atomic bomb to take it off then.-----With proper torque on the nut they come off easy.

Need to float test that one and and replace it. I wouldn't trust it due to impact damage . You should never have to use a air impact to remove a flywheel.

 

[boobie]

When you say lots of heat, you may have ruined the center magnet in the flywheel.

Over torque was the problem i like to have never got the nut off but there was rust in the flywheel when i got it off
