WHEN REUSING AN OLD SEAL, DO NOT ATTEMPT TO SEPARATE THE ROTATING
PORTION OF THE SEAL FROM THE SHAFT SLEEVE. DURING USE THE RUBBER
BELLOWS WILL BOND TO THE SLEEVE AND ATTEMPTING TO SEPARATE THEM
WILL DAMAGE THE BELLOWS.
1. Mechanical Seal Installation
1. Install the sealplate gasket if the sealplate was previously removed. Carefully
place the sealplate directly over the shaft, and attach it to the bearing housing
with its hardware. Next, lubricate the seal plate O-ring with light grease, and
install it on the seal plate.
2. Stretch the O-ring over the shaft sleeve that is provided with the mechanical seal
to prevent damage to the O-ring. Slip the shaft sleeve over the threads, sliding
the O-ring off the shaft sleeve onto the shaft. After removing the shaft sleeve,
continue sliding the O-ring down the shaft until it seats itself against the shaft
shoulder then use light oil to lubricate the shaft sleeve O-ring.
3. To install a new seal assembly, unpack the new seal, and using the stationary
seal seat holder, lubricate the external stationary seat holder O-ring and the bore
of the sealplate where the seal will be installed with light oil.
4. a. Lubricate the shaft sleeve with lightweight oil.
b. Lubricate the inside of the bellows in the rotating head assembly with
lightweight oil.
5. a. Put the shaft sleeve into the seal face side of the rotating head. This is
located on the opposite side of the I.D. chamfer for the shaft sleeve O-ring.
b. Hand-press the shaft sleeve firmly into the rotating head until the sleeve is
even with the rotating head seal face. Be extremely careful to avoid
damaging the seal face (Figure 7).
6. a. Wipe any grease or debris from the sealing surface of both the stationary and
the rotating seal faces with a clean, lint-free cloth.
b. Use 1-2 drops of light oil on one seal face, and install the shaft sleeve onto
the shaft.
c. Be sure that both seal faces are fully seated and the drive notches in each
face are fully engaged.
7. Press the shaft sleeve firmly through the rotating part of the mechanical seal
until the sleeve will not move forward (Figure 7).
Should it become necessary to reuse an old seal in an emergency, separate both the
stationary and rotating seal faces from the bellows retainer and the stationary seat. Be
careful not to damage the seal faces.
