NOTICE:
Thoroughly clean all debris from the area around the oil seal being replaced in order to keep contamination out of the gearbox when the old seal is removed.
2.
If the oil seal being replaced has a flinger/v-ring installed outside of the seal, pry the flinger out using a sharp-bladed screwdriver.viton seal.
3.
Using a punch with a sharp point, place two or more small holes equally spaced in the face of the seal to be removed. Take care not to damage the shaft or housing.
4.
Insert sheet metal screws in the punched holes, leaving the screw heads sufficiently exposed so they can be pried or grasped with pliers.
5.
Work the seal loose. After removal, be careful to prevent metal or dirt particles from entering unit.
6.
Remove any burrs or sharp edges from the seal bore in the housing, keyway , or shaft shoulder, as applicable, using an abrasive pad
NOTICE:
Do not use abrasive pad on the shaft’s seal surface.
7.
Clean the seat in housing and seal surface of shaft with soft cloth.
8.
Cover the keyway, threads or shaft shoulder with electrical tape. Starting at the shoulder of the shaft’s seal journal, wrap the tape in a spiral pattern progressing away from the shoulder leaving enough electrical tape extending outward to allow for easy removal after the seal is installed.rubber oil seals various size.
9.
Apply a generous amount of grease over the taped shaft.
10.
Protect seal lips from damage during handling. Apply grease to the rubber lip of the new seal. If the seal casing is metal, apply a thin bead of silicone around the outside diameter of the seal just prior to installation. If the seal casing is rubber , do not apply sealant to the outside diameter of the seal.
11.
Start the seal over the shaft with the seal spring toward the reducer and apply just enough pressure with a slight turning rotation to position the seal on the shaft.Verify that no part of the seal lip is rolled inward.Newer style reducers utilizing a v-ring and flinger (see Figure 1), proceed to step 15.

Using a seal installation tool (customer supplied) made from a square faced pipe or tube that fits against the oil seal’s face with an outside diameter larger than the seal’s outside iameter (see Figure 4 but do not use dimension A or B), evenly drive or press the seal until fully seated. Verify seal casing is not bent and the seal is not misaligned in the bore.bearing seal. If dual seals are being utilized (see Figure 3), press the first seal in to a depth equal to the seal’s width using a special installation tool similar to the one described in step 15 with dimension B equaling the seal width. rubber oil seals various size.Apply a good quality grease over the first seal so when the second seal is installed the cavity between the seals is approximately 2/3 filled with grease. Press a second seal over the first so it is flush with the housing face.

Install the v-ring onto the flinger as shown in Figure 5.
18.
Using your finger, place a small bead of a good quality NLGI #2 grease on the oil seal’s surface near the shaft where the v-ring’s lip will ride. Try to keep excess grease off the seal area outside of where the v-ring contacts the seal.
