Volvo Penta Z-drive spare parts

Volvo Penta Z-drive spare parts include components for seals, bearings, bellows, trim systems and transmission assemblies. Precisely fitting parts according to drive series (e.g. SX, DPS, DPH), reference number and year of manufacture ensure reliable power transmission, tight transitions and stable driving performance. The structured allocation reduces incorrect orders and supports professional maintenance and repair in maritime applications.

Design & function of the Z-drive

The Z-drive (star drive) connects the motor and propeller via an angular transmission and enables flexible trimming. It consists of an upper and lower part, gearbox, shafts, bearings and sealing systems. Precise coordination of all components is crucial for efficiency, performance and operational reliability.

Spare parts for seals, bearings & shafts

Typical wear and maintenance components:

Shaft seals & O-rings
Propeller shaft seals
Shaft bearings & needle bearings
Housing seals & seal kits

These parts prevent water and oil ingress, secure bearing guidance and protect internal gear components.

Bellows, trim systems & hydraulics

The Z-drive also includes

Exhaust, shift and gimbal bellows
Trim cylinders & trim pumps
Hydraulic hoses & sensors

Bellows protect against water ingress in the transom area, while the trim system optimizes handling and performance.

Transmission & propeller components

Other relevant spare parts:

Gearbox seals
Gear & transmission components
Propeller shaft parts
Fastening & assembly components

Correct maintenance of these assemblies prevents loss of performance and cost-intensive consequential damage.

Selection by drive series & reference number

Volvo Penta Z-drives differ depending on the series:

SX
DP-S
DPS
DPH / DPR
older 280 / 290 systems

The reference number is the central identification feature for exact allocation. Even minor deviations in sealing dimensions, bearing size or housing shape can cause functional problems.
