4200XL Pump Motor Problem

[A1 Dirt]

No - This is a NEW replacement motor. It should have been ready to roll as received. I expected it to be OE (guess it was, it failed).

The motor shaft is smooth. I took the original motor apart and there are no notches or flat spots. I don't intend to take this one apart.

Depending on what I hear from RC4WD, I'll probably try knurled cove point set screws, then cone point, then cone point after drilling a detent.

As a last resort, I'll try a retaining compound. I called Loctite and the lady said that Loctite 290 is a wicking threadlock that can be used as a retaining compound. The only problem might be the shaft/housing tolerance - too tight, too loose, or just right.

There are a few warm, sunny days forecast and I'm anxious to get this digger outside in the dirt
