23290086 Upper Gear | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Silent Shift upper gear, weighing 32.205 kg and listed for 152 applications across V, SX, DPS, FWD and D series engines and drives. It replaces the existing upper gear and its cone clutch with a multi-plate clutch for smooth, near-silent shifting, and mates with the lower gear of the drive already fitted. This is the unit listed against SX drives with the 1.51, 1.60 and 1.66 ratios, DPS drives with 1.78 and 1.95, and FWD drives with 1.95, covering SX-A and newer, DPS-A and newer, and all FWD versions. It shares its weight exactly with 23290085, so the ratio group is what separates them. It consolidates five earlier references.
