Hot mid shaft

[RiverRat]

Installed a new midshaft housing, bearings, midshaft, seals and coupler. Motor and pump seem to be aligned correctly. What could cause this issue? Bad bearing?

I thought it was the crank bearings going but midshaft was much hotter than the crank.

It must be stolen.

I never would have believed it but seals riding on the midshaft create a lot of heat. The double lip seals create even more heat and are used as the front and rear seal in the blasters.

Humm...... So as it wears i guess it will get better . Everything spins smoothly and I don't feel any vibration when running.

Installed a new shaft and housing in a brand new build and it did sane thing but eventually went away
