SHAFT SEAL INSTALLATION
Pre-Installation
After all the old seals have been removed, the inside of the bushing
should be cleaned to ensure no debris is left that may cause premature
damage to the new seals.
Installation
1.
To prevent damaging the inside surface of the new seal, wrap
electrical tape around each leg of the needle-nose pliers. (Heat
shrink tubing may also be used.)
2.
With a new seal in hand, place the two legs of the needle-nose
pliers inside the seal ring. (See Figure A.)
3.
Open the pliers as wide as the seal diameter will allow, then with two
fingers pull down on the top portion of the seal to form a kidney bean
shape. (See Figure B.)
4.
Lightly clamp the pliers together to hold the seal into the kidney
shape. Be sure to pull the seal into as tight of a kidney shape as
possible. This will allow the seal to travel down the bushing bore
with greater ease.
5.
With the seal clamped in the pliers, insert the seal into the busing
bore and position the bottom of the seal into the correct groove.
When the bottom of the seal is seated in the groove, release the
clamp pressure on the pliers. This will allow the seal to partially snap
back to its original shape.
6.
After removing the pliers, you will notice a slight bump in the seal
shape. Before the seal can be resized properly, the bump in the seal
should be removed as much as possible. This can be done with
either a Phillips screwdriver or your finger. With the side of the
screwdriver or your finger, apply light pressure to the peak of the
bump. This pressure will cause the bump to be eliminated almost
completely.
7.
Lubricate the edge of the shaft with NLGI grade 2 white EP bearing
grease.
8.
Slowly insert the center shaft with a rotating motion. This will
complete the resizing of the seal.
9.
Repeat these steps for the remaining seals.
Tools
The following tools can be used to aid in the installation of
the new seals:
Needle-Nose Pliers
Phillips Screwdriver
Electrical Tape
