1. Have the entire seal kit available and layed out
neatly on the table (fig. C3980). Compare the old
seal kit to the new one to ensure you have the correct
one. Lightly coat all seals with seal grease. The
grease is needed to adhere the sealsin their grooves.
DO NOT INSTALL DRY SEALS!
2. Install the shaft seal into the front flange (if
applicable). Prepare the flange and shaft seal by
lightly lubricating with grease. Seat the seal in the
flange by hand. Then, using a shaft seal installation
tool press the seal until the tool stops on the flange.
This will insure the seal is inserted to the proper
depth.
3. Install the snap ring using internal snap ring
pliers (fig. 3981). Ensure the snap ring fits securely
in its groove. This is necessary to retain the shaft
seal.
4. Prepare the body by cleaning it. Inspect the
internal and mating surfaces. Ensure the surfaces are
free of burrs and scratches. Check both the bearing
block mating surface and the cut-in path.
5. Prepare the gears (fig. C3982). Caution, the gear
surfaces are superfinished. Residue on hands and
fingers may be corrosive to this surface. DO NOT
TOUCH. Carefully clean the two gears. Inspect the
journals and the flat faces on the top and bottom of
the gears. Ensure these surfaces are free from burrs
or scratches. If scratches are found, clean them with a
flat stone and/or very fine emery paper. Rewash the
gears after this operation.
