I am in the process of replacing my main bearings on this engine and came across several issues in the process of disassembling the motor. I have removed everything so that I'm down to getting the rod off of the piston, sliding the piston out, removing the rod from the crank and pushing the crank out the back of the engine. Is that sequence correct?
1) I am having trouble getting the wrist pin item #13 (P/N 45506010) on the parts list out of the rod/piston assembly. I understand it comes out the hole in the rear of the cylinder casting but am unable to coax it out. When I look on the exploded view in the manual I see a piston pin retainer item #14 that appears to be a spring clip on the end of the pin facing the front of the engine. Is this preventing me from removing the pin? Please advise best way to remove the wrist pin.
2) During the process of trying to remove the wrist pin I slid the cylinder liner up to expose the wrist pin to the hole in the rear of the housing; inadvertently the liner slipped past the piston ring. When I finally get the piston out of the cylinder I was planning on compressing it and sliding it back into the liner. Is there any problems with that fix?
3) I will be replacing the cam cover due to damage removing it, and was going to replace the bearing in it which I assume is accomplished by heating the cam cover then sliding a room temp cam bearing into it is that correct?
4) I heated the motor to break loose the cylinder liner when I did that the cam bearing that is opposite the cover was in the casting, will the heat affect it? If I wanted to replace it how would I?
5) When I removed the cam from its housing I didn't notice its orientation. I'm not referring to timing which I believe has the lobe closest to the cam cover pointing up along the push rods at TDC. What I mean is which end goes into the housing first, one end has an oil hole in the center-line of the cam does it face towards or away from the cam cover?
Any help on these issues is appreciated, and any reference to detailed instructions for bearing replacement would be appreciated.
