I have noticed frequent posts on the board that mention or discuss a problem that is the same as I have with my D17. That is, Leaking Rear Seals on WD45 or D17's. I'm not aware of a big problem on the other Makes of Tractors. Is there something that can be done in servicing the engine that will act as a preventative measure? Or is this just an engineering design failure for these tractors?

Thanks

Don

There's nothing specific in engine maintenance that will make the seal last longer. If it starts leaking, it's usually time for an engine overhaul anyway. Where a problem may come from is that people tend to install new seals incorrectly. The seal is in two parts, upper and lower. You have to get a special glue available from AGCO to cement the seal into the upper and lower holder(the upper seal holder is bolted onto the back of the block while the lower is integral with the rear main bearing cap). Some people don't use the glue, allowing the seals to move which can result in a leak. Also, some people will trim the ends of the seal after they're installed in the holders. It looks nice but that removed material allows a place for oil to leak. The seals stick out on the ends just slightly and when that rear bearing cap is tightened down, that material crushes together forming a tight seal. So, to answer your question, the rear seal works fine when installed correctly. Others may be easier for shade tree mechanics to install. I have put two seals in two different D17's when overhauling them. Both were several years ago. One has a slight film of oil underneath it if you wipe your finger across the bottom of the bell housing, but none ever drips on the floor. Neither tractor uses any oil in 100 hours of running. I just followed the instructions in the Allis-Chalmers service manual and had good results even though I'm not highly experienced mechanic. One other thing, there are two small gaskets kind of in the shape of an "F" that also get installed uder the rear main bearing cap in the area of the rear seal. I've heard of aftermarket kits that did not have those two gaskets, also making leaks more likely. Kits from AGCO have them.
