Step 1: Inspect the Seal Application Before Removal

Amount of Leakage: Slight
Seal Area Damp
Heavy Leakage
Identify where the leakage is coming from:

Step 2: Wipe the Area Clean & Inspect

Check conditions found: Nicks on Bore Chamfer
Paint Spray on Seal
Seal Cocked in Bore
Seal Loose in Bore
Seal Case Deformed
Seal Installed Improperly
Shaft to Bore Misaligned

Step 3: Rotate Shaft if Possible

Check Conditions: Excessive End Play
Excessive Run-out

Step 4

If the location of leakage cannot be confirmed at this point, either introduce ultraviolet dye into the sump or spray area with white powder, operate for 15 minutes and check for leakage with ultraviolet light.

Step 5: Mark the seal at the 12 O'Clock Position and remove it carefully

Retain an oil sample: Yes   No
Compare to the original fluid and describe the difference, if any:

Step 6: Inspect the Application With Seal Removed

Check conditions found: Shaft Damage
Shaft Clean
Shaft Corroded
Shaft Discolored
Rough Bore Surface
Flaws or Voids in Bore
Coked Lube on Shaft

Step 7: Inspect the Seal
