1. Disconnect the Red and Black leads from the Connector
(Item 30), located on the Solenoid Valve, from Terminals 5
and 6 of the Connector (Item 33) by pushing a screwdriver
into the slot on the top of the Connector; then, pull the two
leads from the Solenoid Valve out of the Connector (See
Figure 13).
2. Remove the four Socket Head Cap Screws (Item 24) and
remove the Female Pilot (Item 13) from the FMCE Housing
(Item 1) (See Figure 13).
3. Remove the Retaining Ring (Item 6) (See Figure 13).
4. Press the Drive Disc (Item 4) out of the Bearing (Item 2) and
the Female Pilot (Item 13) (See Figure 13).
5. Remove the Retaining Ring (Item 3) (See Figure 13).
6. Fully supporting the Female Pilot (Item 13), press the
old Bearing (Item 2) out of the Female Pilot (Item 13) (See
Figure 13).
NOTE
If an Input Unit is installed on the FMCE, it
must be removed before servicing the FMCE.
Remove the Plug (Item 27) and loosen the Set
Screw (Item 26) to release the FMCE from the
Input Unit (See Figure 13).
CAUTION
Use caution not to bump or damage the
Sensors during assembly or disassembly.
NOTE
Do not reuse the bearing. Applying force to
the inner bearing race to remove a bearing
held by the outer race causes damage to
the bearing.
7. Clean the bearing bore of the Female Pilot (Item 13) with
fresh safety solvent, making sure all old Loctite ® residue is
removed (See Figure 13).
8. Apply an adequate amount of Loctite ® 680 to evenly
coat the outer race of the new Bearing (Item 2) (See Figure
13).
9. Carefully align the outer race of the new Bearing (Item 2)
with the bore of the Female Pilot (Item 13) (See Figure 13).
10. Supporting the Female Pilot (Item 13) and pressing on the
outer race of the new Bearing (Item 2), press the new Bear-
ing into the Female Pilot (See Figure 13).
11. Reinstall the Retaining Ring (Item 3) (See Figure 13).
12. Support the inner race of the new Bearing (Item 2) and press
the Drive Disc (Item 4) into the new Bearing and Female
Pilot (Item 13) (See Figure 13).
13. Reinstall the Retaining Ring (Item 6) (See Figure 13).
NOTE
If you are replacing all the Bearings and
O-ring Seals in the FMCE, proceed to PARTS
