A Transmission/transaxle question

[Steve in MT]

I hauled home what was left of a large ag/field sprayer that has a 3 speed transaxle on it. I found in the aux transmission section of this site  a transmission in a OC-3 that is a near replica of what I have. As near as I can tell Oliver/Cletrac used Clark brand transaxles? I found a very sketchy parts brake down of a Case 310 crawler that also appears to be the same as Cletrac, how ever, the the gear part numbers and gear tooth count are not the same. I can not find any Clark transaxle info anywhere. Does anyone know where to send me for parts and info? I need a input shaft and second gear. The casting on the gear case is 200362 and the stamping number on the case is 116874G. The number on 2nd gear is 205872 , has 18 teeth and rides on the 10 spline input shaft. If anyone has a transaxle parts break down with the part numbers on it, I would really appreciate it if a copy could be posted here or sent to me by email
Thank you for your time.

About 10 years ago I did  a little research on the Clark units. They made that unit for over 20 customers including some sprayer manufactures. Clark had been under a few other companies since then. Dana purchased that part of it and I-R who owned it before had gotten rid of most of the parts. Dana manufactured few if any parts for these units. Send me a reply however I will admitt I lost 90 +% of my information when my basement flooded a few years ago. John
