4. Remove the Retaining Ring (Item 5) from the Piston
(Item 8) (See Figure 16).
5. Press the old Ball Bearing (Item 21) out of the
Piston (Item 8) (See Figure 16).
NOTE: Do not reuse the old Ball Bearings. Applying
force to the inner race to remove a ball bearing held
by the outer race causes damage to ball bearing.
6. Clean bearing bore of Piston (Item 8) with fresh
solvent, making sure all Loctite ® residue is removed.
7. Apply an adequate amount of Loctite ® 680 to evenly
coat the outer race of the new Ball Bearing (Item
21) and press the new Ball Bearing into the Piston
(Item 8) (See Figure 16).
8. Reinstall Retaining Ring (Item 5) (See Figure 16).
9. Press the old Ball Bearing (Item 22) and Drive Ring
(Item 10) out of Cylinder (Item 9) (See Figure 16).
10 Using a bearing puller, remove the old Ball Bearing
(Item 22) from the Drive Ring (Item 10) (See Figure
16).
11. Clean the bearing bore of the Cylinder (Item 9) with
fresh solvent, making sure all old Loctite ® residue is
removed.
12. Apply an adequate amount of Loctite ® 680 to
evenly coat the outer race of the new Ball Bearing
(Item 22) and press the new Ball Bearing into the
Cylinder (Item 9) (See Figure 16).
13. Supporting the inner race of the Ball Bearing (Item
22), press the Drive Ring (Item 10) into the Cylinder
(Item 9) and new Ball Bearing (Item 22) (See Figure
16).
14. Lubricate the new O-ring Seals (Items 12 and 13),
Back-Up Ring Seals (Items 11 and 14), and seal
contact surfaces of the Piston (Item 8) and Cylinder
(Item 9) with a thin film of fresh o-ring lubricant (See
Figure 16).
NOTE: When installing new O-ring Seals (Items 12
and 13) and Back-Up Ring Seals (Items 11 and 14),
make sure the curved surface of the Back-Up Ring
Seal matches the curved surface of the O-ring Seal.
Back-Up Ring Seals must be installed on the non-
pressurized side of the O-ring (See Figure 17).
15. Install new O-ring Seals (Items 11 & 14) and new
Back-Up Ring Seals (Items 11 & 14) (See Figure
16).
16. Press the Piston (Item 8) back into the Cylinder
(Item 9) (See Figure 16).
