Good question, Duane. The shop said the gerotor's had enough wear themselves that a seal kit probably wouldn't be effective. However, there was a gash that appeared to have been caused by a piece of metal being pumped through the hydraulic motor. (Apparently, that isn't all that uncommon...???) Anyway, he said that given the wear and the gash, that a seal kit probably wouldn't last very long. I remember the guy that I bought this machine from telling me he'd "had some problems" with that wheel motor. Apparently he did the easiest fix, which was having a seal kit installed.
Regardless, a local hydraulic supplier and this hydraulic repair shop have both said that this Parker TB0230 model is a "throw away" wheel motor, meaning that when it wears beyond repair you just throw it away and replace it with a new one. Wish the previous owner had taken that approach!
Now, note that my unit is 13 years old, and the newer units may or may not still use "throw away" wheel motors. I know the current wheel motors are different (both 422 and larger 425 motors) because Terry had to do some digging for info and actually never did get back to me. So I'm pretty sure they're not still the same model as my old one.
HTH,
Dave
