Ray Erspamer came out today with his bearing tool to take my front hubs apart. It was a learning day as he has zerks on his GMC so he has never had to use his tool.
After getting the bearing cleaned up and reading the markings here is what I have:
LH outer bearing Bower Japan LO 104949E
LH outer race Timken USA LM104911 "6478"
LH inner bearing Timken USA LM104949E SY "6478-A"
LH inner race Timken USA LM104911 VY "6478-A"
LH spacer LM104911 ".006 6478"
RH outer bearing Timken USA LM104949E SY "6437-A"
RH outer race Timken USA LM104911 VY "6437-A
RH inner bearing Timken USA LM104949E SY "6437"
RH inner race Timken USA LM104911 VY "6437"
RH spacer ".006 6437"
(the numbers in "quotes" are hand etched)
The bearings and races pressed off with the expected force, good interference fits. No signs of wear, overheating, or damage on bearings, races, hubs or knuckles.
I have two concerns. The LH outer bearing does not appear to be part of the "6478" set. I'm not sure how the ".006" marked on the spacers relates to the .095 dimension I have seen referenced for these bearing sets.
Any comments or advice would be appreciated.
