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
