20860794 Gear | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Crankshaft Drive Gear - Part Number: 20860794

A genuine Volvo Penta crankshaft-mounted drive gear used in the engine timing and auxiliary gear train. The gear's tooth form, pitch diameter and mounting relationship are produced to maintain the exact phase and backlash required between the crankshaft and the mating gears.

Correct selection must be confirmed against the complete Volvo Penta product designation, product number and serial number because neighbouring engine variants can use different dimensions, connections, calibration or serial-controlled revisions.

🔌 Function

The gear takes rotary motion directly from the crankshaft and transfers it into the engine gear train. Because the crankshaft is the timing reference for the entire engine, tooth position and backlash at this gear directly affect valve timing, fuel-system drive and accessory operation.

Common signs of failure:

• Abnormal gear whine, rattle or impact noise

• Pitted, chipped or polished tooth flanks

• Excessive backlash or metal debris in the lubricating oil

• Timing marks no longer align after gear movement

• Loose fit, fretting or damage at the crankshaft mounting interface
