Just got my old 100 unstuck and noticed when cleaning up the cylinders and piston top that the #4 "FRT" arrow is pointing back where the other three are pointing forward. Was wondering what this hurts; do I need to turn it around or leave it, no telling how long ago this happened or how long it ran this way. Matt.

Thanks for the input guys, I'll probably get back into it this weekend and let you know about it. Was thinking of running a hone lightly down a couple of the cylinders anyway. That would erase the problen of turning the piston around?,. Matt

Honing will do no harm, and might ease the problem especially if the piston is in excellent shape with no scoring.

Was the rod in backwards too?

I pulled an old AC WC apart to replace the orings and found 3 different pistons. It is simply amazing.

I bought a heavily used C from a local cabbage grower and he complained that after an engine o/h "it didn't run much better than before". He thought the machine shop just spray painted the head and gave him a bill. Well 20 years later I send the head in for o/h and my shop said it doesn't need anything. I went to put in new rings and find that the fire-crator pistons are all backwards. No wonder it didn't run any better! It did work everyday for 10 years like that.

I would check if the piston is on the rod the wrong way or if the rod is in the engine the wrong way. You can tell if the rod is in the engine correctly as typically the cylinder number stamped on the rod and cap will face toward the camshaft side of the engine.

If the rod is in wrong, definitely turn the rod around so that it is in the motor correct, then put the piston on the rod wrong so that it is still in the engine wrong. If the piston is on the rod wrong, I would probably leave it. My thinking behind this is as follows:

Rods are manufactured with considerations for lubrication and rotation on the crankshaft. Therefore, if the rod is on the crank incorrectly, I would correct it. However, the piston and sleeve have worn to mate to each other over time, so I would leave their orientation as they currently are.

My 2 cents.

(I'll probably get some flack for this though!) :>)

The Super C I just sleeved had all of the rods turned around. It looks like it had a lot of hours on it that way (the ring end gap was over 0.080"). I turned the rods back around.

The rest of the first rebuild looked pretty good, I wonder why they turned the rods around? Looks like it would have to be intentional, they were all the same direction.

The rod on that engine is pretty basic. I'd say it's more important, (or at least AS important) that the piston is oriented correctly.

Of course, it did survive HOW MANY hours put in wrong??? A testimony to the toughness of this old iron!!!
