P-22 Removal Question

Got my first Boost ('23 carryover) a few weeks ago. I just ordered a EPI PCP-24 puller for the P-22 and getting a P-85 put together to replace it.

Can you remove the whole clutch with the P-22 puller or do you need to remove the cover and moveable shealth before using the puller just on the inner sheath?

And can see why the P-22's are grenading with all the loading on the just clutch bolt, unlike the threaded spider on the P-85. What a crazy design.
 
I got 1/4 turn re-torquing the P-22 to 110lb after 1st ride. Not surprising that these things are flying off!

I bet, and I hear lapping the end of the crank helps also. Definitely can’t hurt. I guess Patricks is sending out lapping compound with every clutch that they balance.
 
I tried to remove my p22 to lap it…as hard as I could go with a 3’ breaker bar and it wouldn’t break loose, so just put the stock bolt back in at 140 ftlbs.
 
The “Grease Method” is sweet when done properly. Fill with grease, wrap a round or two of electrical tape on puller threads, insert puller and start cranking it in. The clutch usually pops off before the end of the puller ever touches the crank.
 
Tap the side of the head on the puller, not the end. Remember I said tap!!! Should pop.
I've been doing that for a while now when the clutch doesn't pop easily. Like you said, tap it - all you're doing is introducing some vibration. I'm sure someone's damaged crank bearings by whacking the puller like they're trying to drive a railroad spike... I'll also add that tapping up and down the shaft of the puller sometimes helps.
 
Grease not only makes a mess, believe it or not, we swelled the stationary on the old 800 clutch. Remember those.
We have used rubbing alcohol instead of water. Dissipates fast.
Pressure is pressure so how did the grease cause the stationary to swell when the same pressure with alcohol or water wouldn't? Or am I miss-understanding?
 
Pressure is not pressure when different compounds are involved.
Throw water in your hydraulic reservoir…..
Run power steering fluid in your truck brake system.
You’ll be surprised.

Now you are talking viscosity, lubricity and sealing potential. I am saying if a clutch pops off at 1000 psi it will do it with water, air, oil, grease or anything that can be pressed to that pressure. Sure grease is easier to seal than water or air but in this case that is all it does better.

Not true.
None of those will perform the same function of pressure.

Please educate us then. Give us the math to show how different liquids react to static pressure differently when temperature, is not introduced. Even gases, although compressible will rise in pressure if they are pressed adequately. Liquids are generally accepted as non-compressible. In the simple act of popping a clutch off we are not relying on lubricity, viscosity etc.
