24487993 Thrust Washer Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta thrust washer kit 24487993, from the Engine group. A thrust washer takes the axial load on a rotating shaft and sets its endfloat — the small amount of fore-and-aft movement the shaft is allowed in its housing. In an engine the best-known example is the pair either side of the crankshaft thrust journal, and washers of this kind are supplied as a kit because they are fitted as a matched set and are commonly offered in graded thicknesses so that endfloat can be brought back within the workshop figure. The listing does not say which shaft this kit serves, and publishes no thickness, grade or engine application, so both the location and the grade must come from your engine's own parts listing and workshop specification.

⚙️ Key Features

• Thrust washer kit supplied as a matched set
• Engine group
• No published thickness or grade — set endfloat by measurement
• No published engine application

🔌 Function

Takes the axial load on the shaft it is fitted to and sets that shaft's endfloat, keeping it located fore and aft in its housing so that bearing alignment and running clearances stay as designed.

⚠️ Common Signs of Failure

• A heavy knock or thump that changes as the boat is put into and out of gear
• Measured endfloat outside the workshop figure
• Scoring or scuffing on the thrust faces, or a copper-coloured patch where the bearing material has worn through
• Bearing debris in the sump or caught in the oil filter
• The crankshaft pulley visibly moving fore and aft as load comes on

🛠️ Service Notes

• Endfloat is a measured figure — set it with a dial gauge or feelers against your engine's workshop specification, not by feel
• If the thrust faces have worn through, inspect the shaft's thrust journal as well; a scored journal will ruin new washers quickly
• Thrust washers are supplied and fitted as a set, so establish the thickness your engine needs before ordering
