Volvo Penta reversing clutch oil change: here’s how!

Regularly changing the oil in your Volvo Penta reversing clutch prevents wear and malfunctions. In this article, you’ll find out which oil you need and how to carry out the maintenance yourself, step by step.

The reversing clutch of your Volvo Penta engine is crucial for smooth and reliable propulsion. Regularly changing the reversing clutch oil extends its lifespan and prevents costly repairs. In this article, you’ll learn exactly when and how to do this, including the correct oils for Volvo Penta reversing clutch.

  • 1. Why change the reversing clutch oil?

    The gearbox contains gears and friction plates that are constantly under load. Over time, the oil ages and loses its lubricating properties.

    Contaminated oil can lead to:

    • Accelerated wear of gears and bearings
    • Poor shifting or slipping gearbox
    • Overheating and possible severe damage

  • 2. When should you change the oil?

    Maintenance intervals vary depending on the gearbox model. Always check your manual. General guidelines:

    - First oil change: after 25–50 operating hours
    - Then: annually or every 100–200 operating hours

  • 3. Which oil should you use?

    Always use the oil recommended by Volvo Penta:

    Reversing clutch Oil

    MS2 / MS2B ATF Dexron II

    MS25 / MS25L SAE 15W-40

    HS25A ATF Dexron II

    Not sure? Always consult the service manual.

    Tip: We supply both ATF Dexron II oil and SAE 15W-40 engine oil for Volvo Penta gearboxes.

  • 4. Tools & materials needed

    • Hand pump or vacuum pump
    • New oil according to Volvo Penta specifications
    • Funnel or oil syringe
    • Rags and drain container
    • New drain plug sealing washer (if applicable)

  • 5. Step-by-step: Changing the oil in a Volvo Penta reversing clutch

    1. Warm up the engine – Let the engine run for a few minutes so the oil becomes thinner.
    2. Drain the oil – Pump out the old oil or drain it through the plug.
    3. Check the drain plug – Clean the magnet and replace the sealing washer if necessary.
    4. Fill with new oil – Add the correct quantity as specified in the manual.
    5. Check the level – Use the dipstick to check, run the engine briefly, and check again.
    6. Dispose of the oil – Take the used oil to an authorised recycling point.

  • 6. Reversing clutch maintenance tips

    • Check the oil level regularly
    • Always shift at idle speed to avoid wear
    • Only use genuine or approved oils
    • Change the oil on time, especially after a busy boating season

Veelgestelde vragen

Welke olie moet ik gebruiken?

Voor de meeste Yanmar keerkoppelingen wordt SAE30 olie aanbevolen. Controleer je handleiding om zeker te zijn.

Hoe weet ik of de olie aan vervanging toe is?

Vervang de olie als deze donkerder wordt of een verbrande geur heeft. Regelmatige inspectie helpt dit te bepalen.
