Removal
1. 1. Using snap ring pliers, remove retaining ring (G0030).
2. 2. Use a slide-hammer style puller to remove seal (G0020). Be careful not to damage the shaft or seal
bore when removing. Discard seal.
Inspection
Inspect retaining ring for wear or damage. Replace if necessary. Inspect shaft for wear or groove at seal
area.
Assembly
1. Lubricate inside diameter of new seal. Cover the shaft splines with shaft cover or packing tape to
avoid damaging the seal during installation.
2. Using seal installation tool, press seal into housing bore.
3. Using a snap ring pliers, install retaining ring (G0030).
4. Use seal installation tool to press seal and retaining ring into housing until retaining ring snaps into
its groove.
If not using seal installation tool: Do not press seal beyond snap-ring groove. Stop pressing just when
you have room to install the retaining ring into the bore. Pressing the seal and snap-ring together
ensures proper installation depth. Using the seal installation tool prevents pressing the seal too
deeply.
