The tag on my Sunstrand hydrostat says that the model is a 90-1122. From what I've seen and read it is the same as a 15 series. So what does the model number mean? Is it really a 15 series? The owners manual for the Massey 14 says that it is a HT 90-1122.

I would imagine the 90-1122 is the designation Sunstrand assigned to that specific model used in the Masseys.
It really is a 15 series model. Service manual located in our manual section.

You can also find a document I put together that shows all the exploded parts and how easy they are to rebuild.

It is sundstrands model number. The sundstrand number on the Wheelhorse D and C series pump is 90-1193, There are a few internal differences between that and yours but both are based off the 15 series pumps.
