"Manic-Mechanic" 1,195 #1 Posted April 8, 2022 (edited) I have the replacement parts for this 90-1137 Sundstrand. Spline Washer is a 15 spline, 106641,very illusive! Pump Shaft 200213 Coupling 102622 Coupling Driven 103029 I have these on a shelf for years! Now, is it imperative to track down the Spline Washer & Washers, or can I put it back as original with grease? The original Pump Shaft from the 18 Auto didn't have a threaded hole. That is why I think this one to be 200213 There was mention of this threaded hole being utilized to help retain the Driven Coupling? Toro/ Wheel Horse just start using this same shaft for all Sundstrand applications? The 18 Auto, seems to be the predecessor to the D-Series. The Spline Washer and other parts found in the 1978 Service Bulletin, were not used early on, as my old Pump Shaft can attest too!

pacer 3,174 #3 Posted April 9, 2022 Cant give any specific info on that splined .... washer/spacer? except to say in all 5 of the D's I have owned I never ran across one. Now that coupler ----- is VERY elusive, handle it with love and care!! I didnt even need one, but when one popped up here on the forum for sale recently, I jumped on it ..... the last one that broke on me took 6-8 months of searching before I found a replacement. 15 hours ago, "Manic-Mechanic" said: ,very illusive 1 Share this post Link to post Share on other sites
JoeM 7,874 #4 Posted April 9, 2022 Space,,,Just wonder if a man could make one from an old sunstand hydro pulley by slicing it off the end that slide on the shaft. IDK. I had a D and it crapped the splines off of the coupler. I think if that spacer was not there that would engage better. 1 Share this post Link to post Share on other sites

Yes, I'm on the fence about it, had replaced the pump over ten years with semi-strong pump (should've rebuilt it first) it was from another unit running 10-w30 as was the motor. Not having a spline issue per say, but would like more power. I will rebuild the original and follow the tutorials found here, I seen that idea on here awhile back, this one.

Exactly, I seen this one and the Drive Coupling on here way back then, even found a used splined shaft in great shape an d jumped on it. I believe that was "D" Man. I had found him again, he offered one but never replied? Odd. I seen also the 18 Auto never had one nor did it have threads in the end of the shaft for whatever reason. I imagine the Service Bulletin came out for to address this issue. Share this post Link to post Share on other sites
