Crankshaft Main Oil Seal Installation Tool

This crankshaft rear main oil seal installation tool is designed specifically for all Type 1 air-cooled VW engines from 1200cc to 1600cc, providing a safe and accurate method of installing the rear main seal without causing damage. The rear main seal is one of the most critical gaskets in the engine, preventing oil leakage from the crankshaft area. Improper installation—especially uneven pressure or striking the seal—can lead to premature failure, serious leaks, and contamination of the clutch.

This deluxe installation tool eliminates these risks by applying even pressure across the entire seal surface. The central bolt passes through the tool and screws directly into the crankshaft, ensuring perfectly controlled and uniform seating of the seal every time. This makes it far more reliable than improvised methods such as tapping with a drift or hammering in by hand.

Ideal for engine rebuilders, home mechanics, and anyone working on air-cooled VW engines, this tool makes the job quick, clean and fool-proof. It is reusable and built for long-term durability.

Fitment:
• All Type 1 air-cooled engines: 1200cc, 1300cc, 1500cc, 1600cc
• NOT compatible with Type 4 engines (1700cc, 1800cc, 2000cc)
