Remove and Replace Shaft Seals
Shaft seals must be lubricated by using a food-grade polyurea base grease, such as ChevronSM
FM (NLGI 2). Shaft seals are typically replaced at 12-month intervals. Lubricant is supplied the
kit.
Refer to Shaft Seal Kits on
for shaft seal catalog numbers.
Remove the Shaft Seal
The shaft seal can be safely removed by grasping an edge of the shaft seal with a needle-nose
pliers or similar tool. Lift and slightly rotate the seal while pulling it parallel to the shaft and away
from the body of the IDM unit.
Replace the Shaft Seal
No tools are required to install the replacement shaft seal.
1. Apply the lubricant (provided with the kit) to the inner ring of the shaft seal and the
IDM wear sleeve.
2. Center the seal on the shaft with the seal oriented with the sealing lip positioned and
slanting outward, and slide the seal along the shaft toward the mounting surface of the
IDM unit.
3. Press the shaft seal into the seal recess by applying pressure with your fingertips in a
circular fashion that slowly seats the shaft seal.
4. Verify the outer and inner circumference of the shaft seal is fully seated into position.
ATTENTION: Damage to the shaft surface where the seal makes contact can cause excessive wear and
early failure of the shaft seal. Use care to prevent scratching or damage to the mounting surface or to
the IDM shaft.
TIP
Remove the shaft key, if the IDM unit is so equipped, before removing or replacing the shaft seal. Refer
to Remove and Replace Shaft Keys on
IMPORTANT Do not bottom out the shaft seal. Proper seating of the shaft seal to a specific depth is
critical to prolonging the life of your motor.
Insert the shaft seal so the outer diameter of the seal is 1.0 mm (0.04 in.) beneath the
front surface of the motor.
TIP
You can verify the proper shaft-seal seating by running your fingertip around the
seal-to-IDM joint to feel for irregularities in the shaft seal or an uneven alignment where
the shaft seal contacts the IDM mounting surface.
