Am in the process of installing the new pistons and sleeves in my Farmall A. I got a new Tisco rebuild kit with aluminum pistons. On the old ones, it appears it didn't matter which way the pistons faced on the rod. On these new ones, there's a groove cut on the top edge of each piston, which I think is there to indicate which way it shoud face. It appears just by sight that the hole for the piston pin is offset, not centered on the piston--so I am pretty sure orientation DOES matter. There's no paperwork that says which way they should face. Should I have the groove in each piston pointing towards the front (towards #1 cylinder) or in the opposite direction? BTW the rods are labeled, and I know which way to face them, per the service manual. Just need some help "pointing" the pistons the right way....
thanks,
Al

Re: Farmall A: Which way does new piston face?
Yes, generally speaking, a notch on the piston top is intended to be installed toward the front of the engine.

Re: Farmall A: Which way does new piston face?
I know each rod and bearing cap has a number or letter on the side face. These should be assemble on the camshaft side of the engine. I'm with Boss you should contact the manufacture for piston position. Pabst

Re: Farmall A: Which way does new piston face?
the reason i asked was that last one i did had no taper at the bottom of the sleeves. i'd have to go back and look, but i think it was an A&I kit. i had to cut the bottom off an old sleeve, polish it up, and use it as a lead in for the new sleeves.
