I would probably do it that way next time. Last time, I put the piston in
the cylinder with the wrist pin retainer in the far end side of the piston
since it could not be installed after the wrist pin was in place. I mated
the piston to the rod, not too hard. Of course you are working like
orthoscopic surgery through the hole available to you after you remove the
metal water pipe (this on the passenger side rear piston). I could barely
get the pin started into the piston and then use a long brass drift to
drive it in with taps from a flat steel plate. There is not enough room to
swing even a small hammer between the back of the head and the muffler,
hence the steel plate as a hammer. Anway, the pin finally drove home
against the clip I had already installed in the piston, and then I set the
other clip in place with a really long pair of pliers and a couple of dozen
attempts having it spring off in all directions and having to fish it out
of the water jacket of the block with a magnet on a dowel half the time.
Oh, and I skipped the fun part of getting the wrist pin out. I didn't want
to lay into it with the force of an inertia puller, so I held a nut between
the far side of the piston and the barrel of the next cylinder and ran a
piece of all thread into it. The nut has to be smaller than the hole
through the piston but larger than the hole through the wrist pin. From
that I set up some nuts and washers sticking out of the water jacket hole
and ran another bolt down on the all thread to pull the pin out. All in all
it was a challenging fun week. Not.
As I mentioned earlier, I will pull the engine next time before I go
through this again.
