area.

H1F Assembly

1. Lubricate inside diameter of new seal.
2. Using seal installation tool, press seal into front cover bore.
3. Install o-ring on front cover o-ring groove, lubricate o-ring (G0080).
4. Cover the shaft splines with shaft cover or packing tape to avoid damaging the seal during
installation.
5. Install front cover (G0025) into housing (G0010).
6. Using snap pliers, install retaining ring ((G0030).
7. Press front cover 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.
