I bought a homemade mud motor a couple of years ago and it looks like the bronze bushings finally went out. I can see all the scouring from sand a other stuff, and I know the motor is based off of a go-devil. The problem I'm having is that I can't find any shoulder style bushings with such a large flange section. I've attached a picture showing the only two that were at the top and bottom of the shaft as well as the end caps. I do have access to a lathe if i need to make them myself

check with mcmaster, msc, granger, motion indrustrial and theres a few more.

Whats the ID and OD and lenght of the parts and ill look and see what i can find.

I.D. 3/4"
O.D. 1"

flange dimensions
1.120" O.D. X 0.640 wide

overall length = 2.102

There is a motion industries nearby, I'll probably stop by there with the parts and see what they can do. I was also thinking about the possibility of changing out the end caps to allow for a smaller shoulder type bushing.

Also, since I have the shaft completely taken apart I was thinking about switching grease types from the regular lithium to the red lithium grease?
