i have the clyinders off and since their off i'd like to change the tappet block seals but have never done this.how tight are these things in there, i don't have the tool to drive them out is there a good substitute.should i tempt this or just take my chances and leave it.this was a none running bike so i don't know if they were leaking.
also i tried to remove the timing side cover, i could get it about 1/4 inch off and it would hang up. i didn't want to force it so i pushed it back. i was thinking of changing the gasket and polishing the case, whats it hanging up on , would it efect the timming if i removed it.please help.
hi,
you really need the special tool to do this otherwise you ll damage the bores.dis mounting is easy with a good hammer but remounting is tricky cause you need to align the block very accurately before driving it down:the screw on the cylinder block dont hold the tappet block but fix the right position of the block! if you put the block in a false alignment
dont even try to turn it!!!take it out again and retry...
but are you sure they are leaking? personally i would bet they are ok.

it is just that i have the cylinders off and thought that it might be a good idea to change them, but i don't want to take a chance on damage. if you think it best to leave it alone i will.
I posted about this not long ago. I did what was suggested and drove them out using a brass drift and it worked fine. Just be carefull to make sure you hit down straight otherwise you may damage the tangs.

i put it back together without taking the tappet blocks out, i changed all the other seals and gaskets though. i had a copper bar and i hit it one time and figured these are in here very tight and decided not to risk it.
It is almost as risky to leave them IN, if you are sending the cylinders to be honed or re-bored. The lips can be easily broken when jigging them up in the equipment, unless your machinist is aware and careful.
