3094523 Volvo NH12 D12A Clutch Master Cylinder Repair Kit

What does a clutch master cylinder repair kit do?

This clutch master cylinder repair kit is essential for renewing the worn sealing and moving parts within the hydraulic clutch circuit of a heavy commercial vehicle. The kit functions by replacing the internal components that convert pedal movement into the necessary hydraulic pressure required to disengage the clutch via the slave cylinder.

Vehicle and engine compatibility

This specific kit is designed for use in Volvo NH12 trucks featuring D12A engines. It provides a precise fit for the hydraulic clutch control system, ensuring that the pressure-generating link remains efficient under heavy-duty operating conditions.

Installation and maintenance guidance

When maintaining the clutch system, technicians should inspect the piston, cups, O-rings, and dust boot. Replacing these components can resolve issues such as pedal softening or external leaks without the need to replace the entire master cylinder unit. It is recommended to verify all internal components during installation to ensure optimal system performance.

System troubleshooting

Proper maintenance of the master cylinder helps prevent gear-shift quality degradation and ensures consistent clutch engagement for fleet managers and workshop technicians.
