Shaft Seals
Inspect the sealing area on the shaft for rust, wear, or
contamination. Polish the sealing area on the shaft if
necessary.
Wrap the spline or keyed end of the shaft with with a thin
plastic or cellophane to prevent damage to the seal lip
during installation.
Lubricate the new seal with petroleum jelly and slide the
seal over the shaft and press it into the housing bore. Be
careful not to damage the seal.
Install the retaining ring in the housing.
The pump through shaft, motor output shaft and displace-
ment control shaft may be replaced following a similar
procedure as outlined for the pump input shaft seal. These
seals are not held in position by a retaining ring.
