Workshop sequence
General workshop guidance only; use the service procedure for your exact drive or engine configuration.
- Verify the full sterndrive designation on the transom assembly and compare the removed gimbal bearing, U-joint bellows, exhaust bellows and seals against the reference numbers on this page before disassembly.
- Clean and inspect all transom housing and pivot housing mating surfaces so old adhesive residue, corrosion or debris cannot interfere with bellows seating or seal contact.
- Seat the gimbal bearing, seals and bellows without twisting or pinching the bellows folds, and follow the Volvo Penta or OMC service manual for orientation, clamp positioning and any required sealants or tools.
