Installation Guidelines

Proper installation is critical to achieving optimal sealing performance. Follow these steps for a flawless fit:

1. Preparation: Clean the crankshaft housing and surrounding area with a solvent that removes oil, grease, and debris.
2. Seal Positioning: Align the seal ring so that its inner lip faces the crankshaft journal. Ensure no burrs or sharp edges are present on the mating surfaces.
3. Insertion: Gently press the seal into place using a soft‑tipped tool to avoid damaging the rubber. Avoid excessive force that could deform the ring.
4. Torque Specification: Tighten any associated bolts or fasteners to the manufacturer’s recommended torque value, typically between 10–15 Nm for front crankshaft seals.
5. Final Check: Inspect the seal for proper seating and verify that no oil is leaking around the installation site during a brief engine run.
