Ive been reading what other have to say, Good post all good advice, take all
into consideration,,check and make sure the thin Oil control rings are
correctly installed on the ledge of the spring spacer ALL THE WAY AROUND, you
should be able to easly rotate the Oil ring assemebly around in the groove of
the piston and side to side, the thin rings should be installed so that the end
gaps are 180 degrees apart and the ends of the spring spacer 90 degrees to the
thin rings, Take extreme caution when installing the pistons making sure they
are in the correct bore and facing the correct direction,I like to rotate the
crank away for the bore im working on then install the piston in the bore
nearly to the oil ring, then clamp on the spring compressor tightly.. Just
covering the bottom ring by 1/4",using the deck of the block to insure that the
compressor is square with the bore,, then using the wooden handle of a fairly
heavy hammer, tap and push at the same time, you should have the piston in
level with the deck in just a few taps, if any resistance is encountered where
no movement is seen and you get a heavy thunk Dont proceed,bcak out and start
over, it shouldnt require that brute force is needed to install pistons, Piston
damage and ring damage can occur, some times the compressor thin metal skirt
can enter the bore and jam between the bore and the piston,, becareful take
your time, (Its important to check the clearance on the rod bearings also, But
I wont go into that here), after each piston is installed and the rod cap
torqued to the proper spec., turn the crank over one revolution to make sure
that every thing moves freely, use plenty of assembly lube on the bearing to
crank surface and dip each piston in fresh oil before insertion ,,Ricahrd57
