How hard is pulling a pison to replace a pin??

[MHTARSTON]

I need some help. I'm average around the shop. I have never taken a head off, but will need to pull for the removale of a piston. Mechanic said I have a piston pin making noise in one of the back three. Is this a straight forward job that someone with average skills and basic hand tools could accomplish. It's a FJ62, had the engine rebuilt less than 7,000 miles ago but timed out on the work.

do you have a 60 or a 62? really time consuming not hard but you may find alot of hidden cost that you did not think was there before. edit. get a fsm if you have not already

pull the oil pan and go from the bottom, leave engine in rig..maybe that's common knowledge..but is a way I was told to to a quickie on a ring job..

I have no experience wit it..

yep, might as well pull them all

If you have pin noise, it most likely will need more than replacing the pin. The piston and rod will have taken a beating if there was indeed a pin issue. A "farm rebuild" thats a rebuild with out engine removal is possible, however it is an involved process (major surgery).

I had planned on pulling the oil pan a pushing the piston and rod out the top then replacing the bad piston with a new piston and rod. I really want to save this engine its only got about 7,000 miles on rebuild. (Guess not a very good rebuild though)

The pistons have to come out the top so the head does have to come off. I had an issue with my wristpins following a rebuild. One piston was seized so bad that it needed to be replaced. The other 5 pistons were honed to achieve the pin to bore clearance spec'd in the book. I never found a good explanation of what caused the problem. Maybe the clearance was just too small to begin with.

If one pin went bad, it might be a good idea to check them all when you have it apart.

You can get a complete gasket head kit. PM or call Cruiser Dan.
