Supersession Notice
Volvo Penta part number 861564 has been discontinued. The current Volvo Penta service replacement is 24677538. If your engine originally specifies 861564, order 24677538 as the current OEM equivalent. Belt specification 7PK920 remains the same.
Compatible Applications
Fitment is engine-model and serial-number specific. Several KAD, KAMD and TAMD engines use more than one belt on the front of the engine — confirm this is the water-pump multi-rib belt for your engine before ordering. Do not identify by appearance alone.

Serial Number Fitment Notice
Confirm the complete engine model and serial number before ordering. Belt specifications can differ according to accessory arrangement and production version. Do not select by engine family or physical appearance alone — the wrong belt specification on a water-pump drive can affect cooling-system operation.
Superseded & Cross-Reference Part Numbers

When This Part Needs Replacement
Inspect the belt at every service and replace when there is:
- Cracking across the ribbed surface
- Missing or damaged ribs
- Fraying along the belt edges
- Glazing or a polished belt surface
- Belt squeal or slipping under load
- Visible contamination from oil or coolant
- Irregular wear caused by pulley misalignment or a failing tensioner
- Scheduled replacement interval reached
A damaged water-pump drive belt can directly affect cooling-system performance and should not be deferred once symptoms appear.
Installation Notes
Before installing the replacement belt, inspect the complete pulley path for corrosion, damage, and contamination. On the KAD32P, drive belt 861564 appears as reference #27 in the water-pump schematic alongside tension pulley 861563 at reference #18 — inspect tensioner condition before fitting the new belt.
Also inspect while access is available:
- 861563 — Tension Pulley
- Water-pump pulley
- Crankshaft pulley
- Associated bearings and brackets
- Adjacent drive belts on the same engine
Route and tension the belt according to the Volvo Penta service procedure for the exact engine model. Confirm belt alignment across all pulleys before running the engine.

Parts Desk Insight
The most important thing to know about 861564 is that it’s no longer the current Volvo Penta service number — order 24677538 instead. The belt specification (7PK920) hasn’t changed, just the ordering number. The second thing worth knowing is that these engines typically run more than one belt at the front, so make sure you’re replacing the water-pump multi-rib belt specifically and not confusing it with another belt on the same engine. If the tensioner pulley (861563) shows any roughness or play while the belt is off, replacing it at the same time avoids pulling the belt off again a short time later.
