Crankshaft Oil Seal - Waterboxer Pulley | 025 105 247A

Oil leakage on the pulley side of your crankshaft is usually the first sign that this seal has seen better days. This replacement part (025 105 247A) sits between the crankshaft and the water pump pulley and prevents engine oil from leaking out. For the Waterboxer T3, this is a classic wear part that will need to be replaced sooner or later. Combine this with a new water pump pulley for a thorough overhaul of the front of your engine.
