Finish Thompson M101603-2 Polypropylene Bearing Guide
The M101603-2 is the polypropylene bearing guide used in Finish Thompson PFM and PFP drum pumps. It holds the center bearing in position inside the tube and keeps it concentric with the shaft. It is built in polypropylene, which is what decides where it can safely be used.
Treat it as a service item rather than a permanent fitting. A guide that has cracked or gone oval lets the bearing sit off center, and from there the shaft wears the bearing far faster than it should. When ordering, match the part to the pump as it was actually built rather than to the catalog model alone, since material and size options were specified at the time of purchase.

Frequently Asked Questions
Q: What causes rapid wear?
Dry running, abrasive solids in the fluid, and misalignment during reassembly are the three usual culprits.
Q: Is there a wear limit to measure?
Check for visible ovality, scoring or a loose fit on the shaft, since any noticeable play at this point shows up as vibration.
Q: Should it be replaced in sets?
If the pump has several bearing points it is worth doing them together, because one fresh bearing carrying a worn neighbor rarely lasts.
Q: Does it need a break in period?
No. It reaches its working clearance almost immediately once the pump is primed and running.
