Weinman 135647 Bearing Frame Kit M Frame, 575 Series Pumps
The Weinman 135647 is the genuine Weinman bearing frame kit in the M medium frame size, for 575 Series frame mounted back pull out pumps. The bearing frame is the mechanical backbone of a frame mounted pump: it carries the shaft, both bearings and the bearing cap, and it holds the rotating assembly true against the hydraulic loads the impeller produces.
Once a shaft is running out of true, the mechanical seal is the next thing to go, then the wear surfaces. A frame that has been run with a failing bearing often has a worn housing bore as well, which is why the whole assembly is the sensible unit of replacement rather than the bearings alone.
Frame size is what identifies this kit. Weinman builds the 575 Series on small, medium and large frames, and this is the M medium frame. The frame size is set by the pump model rather than by the motor, so check it against the pump nameplate and the parts list rather than against the driver.

Frequently Asked Questions
Q: Why did the original bearings fail?
In pump service the usual answers are water past the shaft seal washing out the grease, a damaged or unbalanced impeller loading the shaft unevenly, and coupling misalignment. Finding which one applies is worth more than the parts.
Q: Does this affect how the coupling is set up?
Yes. A new frame means the shaft position is back to standard, so the coupling alignment should be checked and reset rather than assumed. Alignment that was compensating for a worn frame will now be wrong.
Q: Does the kit come lubricated and ready to fit?
It is supplied as a permanently lubricated assembly, so there is no bench build and no initial greasing to get right. Follow the Weinman instructions for setting the impeller clearance once it is in place.
Q: How do I tell which frame size my pump has?
It is set by the pump model, not the motor, and appears in the parts list for that model. The old frame casting and the shaft diameter will also identify it if the documentation has gone missing.
