1556700 Thrust Washer | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta thrust washer is a replaceable locating, spacing or bearing-support component used in the rotating-shaft thrust control. It is manufactured to the original Volvo Penta dimensions and interface requirements so the supported component retains the specified clearance, spacing and location. In service, it controls axial movement and provides the sacrificial thrust surface for the matched rotating component. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1556700 against the installed assembly before ordering.

🔌 Function

A thrust washer carries axial loads between a rotating part and its housing or adjacent component, holding correct end clearance. This keeps the assembly running true and prevents metal-to-metal wear on the load-bearing faces.

⚠️ Common Signs of Failure

• Excessive axial play or end float in the assembly it supports
• Visible scoring, grooving or polishing of the washer face
• Measurable thickness loss or uneven wear across the washer
• Metal debris or bronze/steel particles found during service inspection
• Knocking, rumbling or vibration under load from unrestrained axial movement

🛠️ Service Notes

• Note which way round each washer comes off and refit it the same way; where one face is grooved or lined, that face runs against the moving part
• Measure the end float or running clearance after fitting and compare it with the figure in the workshop manual for your engine — thrust washers are what sets it, and some are supplied in more than one thickness
• Renew the pair or the full complement together, never one new washer alongside a used one
• Check the faces the washer bears against for scoring, ridging or heat discolouration and clean off any pick-up before assembly
• Oil the washer and its seat on assembly and prime the lubrication system before the engine is turned under power
