JoelD and 350B reverser

I don't get the terminology - I guess that's the problem. There are no planetaries in that reverser. Maye some bored engineer is choosing silly names? But - each clutch plack has a drum assembly, a piston, and rings - that must be where your number comes from? My 1010 and early 350 Deere reverser book calls the parts in the back - plate T15794,carrier T15791, piston T16011, back plate T15790, and rear spider T13933. The T16010 you cited is called a "carrier" and is basically just a newer piston that holds two rubber sealing rings. It replaced the older T15791 that used iron rings instead of rubber. If your's is bad - I'll take your word for it - but it's usually one of the parts that does NOT need replacement in a trashed reverser. In regard to the shaft - if the splines towards the rear are bad - it's likely the reverser has been loose against the transmission case. It's supposed to be held tight and aligned with dowels. If they are loose - you're kind of in a mess unless you fix it all correctly. How's the other end of the splined shaft setup - e.g. and i.e. the splinded coupler the transmission shaft? When the reverser shafts goes bad, the trans. shaft is also often bad. And again - the isolator is not one unit - it has many separate pieces. And you say the housing seals are siezed - I don't know what you mean. There is an oil seal in front - in the trans. pump housing, and one on the rear in the rear bearing quill. What seals are you talking about?
