Installation Guide

  1. Safety First: Disconnect the negative battery terminal to prevent electrical hazards.
  2. Drain Fluids: Drain the engine coolant and oil completely.
  3. Access Components: Remove the valve cover, timing belt cover, and any accessories blocking access.
  4. Remove Belt: Carefully release tension from the timing belt and remove it.
  5. Align Marks: Rotate the engine manually to align the timing marks on the crankshaft and camshaft pulleys.
  6. Remove Old Gear: Loosen the bolt securing the camshaft gear and remove the old gear from the camshaft.
  7. Install New Gear: Place the new camshaft gear onto the camshaft, ensuring the timing marks remain perfectly aligned. Tighten the bolt to the manufacturer's torque specification.
  8. Reinstall Belt: Reinstall the timing belt and set the correct tension using a tensioner tool.
  9. Reassembly: Reinstall the timing cover, valve cover, and any other components that were removed.
  10. Refill and Test: Refill the engine with fresh coolant and oil. Reconnect the battery, start the engine, and listen for abnormal noises and check for leaks.

Troubleshooting & FAQ

Q: How do I confirm this camshaft gear fits my Volvo Penta engine?
A: Check that your engine model (e.g., AQ131A, 230) and year of manufacture (1979–1993) are listed in our compatibility table. You should also verify that your existing part number is one of the direct replacements: 856239, 855473, or 831972.

Q: What are the signs that my camshaft gear needs replacement?
A: Common symptoms of a failing camshaft gear include a rattling or ticking noise from the engine bay, loss of power, engine misfires, rough idling, or a Check Engine Light related to camshaft timing. A visual inspection may reveal worn, chipped, or broken teeth on the gear.

Q: What is this gear made of?
A: This gear is manufactured from high-strength forged steel, designed to meet or exceed original equipment specifications for durability and precise valve timing.
