Clutch booster cylinder WG9725230041/J – the air-over-hydraulic clutch servo for HOWO heavy trucks. When the driver presses the pedal, compressed air assists hydraulic pressure to actuate the clutch release bearing through the brass pushrod, which keeps pedal effort light on a 371-class tractor. Fitted with a rubber dust boot on the pushrod, a corrosion-protected reservoir body and a square mounting flange with part label attached.

Key Features

Restores light pedal effort when clutch action turns heavy or the pedal no longer returns cleanly
Sealed dust boot keeps grit off the pushrod and out of the release circuit
Direct bolt-in replacement on the HOWO clutch housing – same flange, same line positions

Signs of Wear

A pedal that sinks slowly under steady pressure, clutch fluid disappearing with no visible leak at the master cylinder, or air hissing past the release valve – these point to worn booster seals. Replace the booster rather than chasing repeated bleeding.
