Flywheel Question

Hello all,

I am a newcomer and will try to include everything. I have been trying to pull a flywheel without success. I have been trying to pull with a harmonic puller. I first tried to tighten and whack and tighten and whack. Then I tried using heat and cold to shock. I tried in combination at least once. I have also tried to use PB blaster and left for days under tension.
I have since noticed I don't have loose linkage and now considering not pulling the flywheel. I am concerned after reading about problems with a taper getting lubricant causing problems. I am not sure if it has. Should I pull the flywheel and inspect this or am I overthinking this? Also the flywheel did rise a little less than 1/8 of an inch.

So the flywheel has moved? Wow usually once they move a little they pop loose...Id keep at it..get it off there and replace the key, remove any corrosion - sounds like there may be plenty - inspect everything and reinstall...I dont know what you mean with a taper getting lubricant. You talking about the shaft itself? When I pulled mine I put a light coat of WD-40 to keep any corrosion from re- forming making it easier for future removal - if needed. Just make sure the nut is torqued to spec when you put it back. However, I see yours is a '94 - Im only used to older motors there may be something the experts know that I dont...quite likely actually....;)
 
No lubricant is to be used / or needed when installing the flywheel.--------Note.-------The key locates the flywheel for proper timing of spark.---------The flywheel is driven by the locking tapers when properly torqued.------Tapers must be clean and dry and no damage on them !!!!!!
 
Make sure all puller bolts are screwed in a safe distance and at an equal height.

Secure the flywheel so that it will not turn, then tighten the center plunger as tight as possible.

There will exist a small amount of vertical play in the flywheel/crankshaft.... With a long heavy duty screwdriver, pry bar, a tool of your choosing, pick a spot on the powerhead whereas you can apply pressure and pry the flywheel upwards so as to eliminate that play.

Now.... Belt that center pulley spindle as hard as you can with the biggest hammer you can find. That should do it!

NOTE: A new flywheel key, if installed, should have the flat outer edge of it "straight up & down" in line with the engine itself, NOT in line with the crankshaft taper!

Also... It is important that the taper of the flywheel and the taper of the crankshaft be absolutely DRY!

Let us know how you make out with this flywheel removal problem.
 
If I remember, I think the torque value on the crank nut is 130lbs. This will give you an idea of how tight you have to make the puller before you smack it with a big hammer.
