335 tvx Kellog compressor

I have a Kellog 335 and it's a basket case when I got it,I want to put it back together but I can't seem to find any information about the piston orientation and the rod orientation,the rods have a x on them but I don't know if they face the pulley or the unloader.I noticed that this site has very knowledgeable people on it and thought I would give it a shot.Thanks for your help,I'm a engine builder and a classic car nut and I love tractors.

Sometimes you can pick up clues as to how something was originally assembled.

Look at the top of the pistons, there may be carbon stains that match the pattern of the valves in the head. Also look for scratches in the cylinder wall that match up with scratches on the piston skirt.

Same with the rods, look for scratches in the crank that match the bearing surface.

If the rod caps were mixed, or you don't know which way they go, look for matching oil stains where they were bolted together, or matching scratches continuing from the rod to the cap. If still unsure, assemble the caps and snug the bolts. The meeting surfaces of the bearing should align with each other, no step. You can also try assembling the rods on the crank. Give it your best guess, tighten the cap and feel the fit. If it binds up, it's wrong. You could also Plasti-gauge them, switch them around until both come out as close to that same as possible.

As for which direction the rods go, if there is no off set, and there probably isn't, it will make no difference which way they go. Look at the spacing beside the wrist pin inside the piston. If it is in the middle when assembled, it is right.

If there is an industrial compressor repair shop near you, they may have some information on it. Some compressors are rebadged from other brands, companies merge. They may have parts or manuals from another brand that will match.

5bridgeroad,You might try contacting them and see if they have a rebuild manual for your compressor.

The manual just said to mark piston and rods when you take it apart so it goes back together right,I think I'm going to go to the library to see if there's a repair manual on compressors but if I don't find anything I will get out my magnifying glass to see if I can tell where they go but I was looking for signs of wear marks and really didn't see much.It's really clean on the journals,I really do appreciate the info.Thanks
