Housing-Spindle Disassembly
1. Place unit on bench with Spindle (1A) end down.
EYE PROTECTION MUST BE WORN WHILE PERFORMING THE
NEXT STEP IN THIS PROCEDURE.
2. Using retaining ring pliers, remove Retaining Ring
(1G) from the groove in Spindle (1A).
3. Remove Bearing Spacer (1F) from top of Bearing
Cone (1D).
4. While supporting the unit on Housing (1E) flange,
press Spindle (1A) out of Housing (1E). The Seal
(1B) and “B” position Bearing Cone (1D) should
come out of Housing (1E) with Spindle (1A).
5. Remove “A” position Bearing Cone (1D) from Bear-
ing Cup (1D) in Housing (1E).
6. Lift Housing (1E) off of Spindle (1A).
7. If necessary, press Studs (1N) out of Housing (1E).
Locate Housing (1E) on Seal (1B) end.
8. Remove “B” position Bearing Cone (1D) from Spin-
dle (1A).
9. Remove Seal (1B) from the Spindle (1A).
10. Using a soft steel rod, knock both Bearing Cups
(1C) out of Housing (1E)
