21191828 Camshaft | Genuine Volvo Penta Part

🔧 Product Description

Genuine camshaft used in the valve-train and timing-gear assembly of the Volvo Penta D1-30F marine diesel engine. The cam profiles control valve lift and timing.

🚤 Compatibility

Typically suits:

• Volvo Penta D1-30F

• Engine Family: D
• HP Range: 30 HP

⚙️ Key Features

• Confirmed D1-30F camshaft application
• Precision-ground cam lobes and journals
• Controls inlet and exhaust valve timing
• Works with camshaft gear 21191830
• Requires correct lubrication and end clearance

🔌 Function

The camshaft converts timing-gear rotation into accurately timed valve movement.

⚠️ Common Signs of Failure

• Worn or pitted cam lobes
• Low valve lift
• Scored journals
• Metal contamination in the engine oil

🛠️ Service Notes

• Oil the journals and lobes before fitting and lower the shaft in squarely, without dragging it across the bearings or bearing bores
• Inspect the parts that run with it as a set — followers or rockers, bearings and the drive gear — and renew anything worn; a new camshaft on worn followers will not last
• Line up the gear timing marks and check valve timing before turning the engine over, and never force it against resistance
• Tighten bearing caps and drive gear fixings in the sequence and to the figures in the workshop manual for your engine
• Prime the oil system and turn the engine through by hand for a full cycle before starting, then keep the first period of running gentle
