RE 540/541 Housing/Shaft with Seal Carrier Disassembly & Assembly
Design That Utilizes A Seal Carrier (11)
1. Remove housing (25) from vise and place on a clean flat surface with hub end facing up.
a) Using shaft (26) and rubber mallet, tap seal carrier (11) down to expose wire ring (2).
b) Remove wire ring (2), steel backup shim (3) and high pressure seal (4) from inner bore groove with a long
narrow screwdriver.
c) Lift the seal carrier (11), thrust washer (12) and thrust bearing (21) from the housing bore.
d) Using a small screwdriver, carefully pry shaft seal (7), backup seal (6), and metal backup shim (5) from seal
carrier (11) and discard.
e) Lay seal carrier (11), thrust washer (12) and thrust bearing (21) aside.
Note: If a new thrust washer (12) and seal carrier (11) is included in kit, old items may be discarded.
Note: At this point, all parts should be cleaned in an oil-based solvent and dried using compressed air (for safety,
observe all OSHA safety guidelines). All new seals should be lightly coated in clean oil prior to installation.
2. Place shaft (26) on a clean surface with output end facing up.
a) Place thrust bearing (21) over shaft (26) and then place thrust washer (12) over shaft (26).
b) After thoroughly coating shaft seal (7) and backup seal (6) with clean oil, place plastic installation sleeve down
over shaft making sure to cover all splines, keyways, etc.
c) Making sure lip on shaft seal (7) faces down, push shaft seal down plastic installation sleeve until it contacts
thrust washer (12).
d) Remove installation sleeve.
e) Install backup seal (6) making sure that lip faces shaft seal (See
Figure 1: Figure 1 on page 11 for correct
seal positions).
f) Install metal backup shim (5) down against backup seal (6).
g) Place seal carrier (11) onto shaft with large end facing down.
