Step-by-Step Procedure to Bleed Volvo Penta Trim Pump
- Locate the Trim Pump: Find the trim pump, which is usually located near the transom or in the engine compartment.
- Check Fluid Level: Remove the cap from the fluid reservoir and check the hydraulic fluid level. Top off if necessary with the recommended hydraulic fluid.
- Open the Bleed Valve: Locate the bleed valve on the trim pump. Use your socket wrench to loosen it slightly but do not remove it completely.
- Activate the Trim System: With the engine off, activate the trim switch to raise the trim. This will push fluid through the system and help expel trapped air.
- Observe for Air Bubbles: Look for air bubbles escaping from the bleed valve. Continue to activate the trim switch until you see a steady stream of fluid without bubbles.
- Tighten the Bleed Valve: Once the air is removed and fluid flows steadily, tighten the bleed valve securely.
- Check Fluid Level Again: After bleeding, check the fluid level again. Add fluid as necessary and replace the cap securely.
Expected Results After Bleeding
After completing the bleeding process, the trim pump should operate smoothly. You should notice improved responsiveness when adjusting the trim. If you still experience issues, further investigation may be necessary to check for leaks or mechanical failures.
