Shaft Seal Replacement

1. Park the machine on a level surface, lower cutting
units, engage parking brake and stop the engine.
2. Disconnect the drive shaft from the transmission
(Fig 27).
3. Remove retaining ring, then carefully remove seal
from bore in charge pump cover (Fig. 28). The face of
the seal my be punctured with a sharp instrument (such
as a screwdriver) to aid in prying the seal out, or a slide
hammer type puller may be used to remove the seal. Be
careful to not damage the charge pump cover or shaft.
Once removed the seal is not reusable.
4. Inspect the charge pump cover, new seal, and shaft
for damage. Inspect sealing area on shaft for rust, wear
or contamination. Polish seal area on shaft if necessary.
5. Use a seal installer tool or wrap spline end of shaft
with thin plastic to prevent damage to seal lip during
installation. Lubricate inside diameter of new seal with
petroleum jelly.
6. Press new seal into charge pump cover, being certain
the seal is perpendicular to the shaft. Be careful not to
damage the seal. The outer face of the seal should be
located between 0.056 to 0.096 in. below the outer
surface of the charge pump cover. Install the retain ­
ing ring.
