Overview
The ZF 4657.354.058 PUMP SHAFT is a precision-machined component engineered specifically for the WG190, WG210, and WG230 series transmissions. This OEM genuine part transmits rotational force from the torque converter to the hydraulic pump, ensuring consistent oil flow for clutch actuation and lubrication. Located within the front section of the transmission housing, the pump shaft (SKU: 4657.354.058) interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain precise alignment under high-torque conditions.
Symptoms of Failure
- Erratic gear engagement or delayed shifting — A worn pump shaft reduces hydraulic pressure, causing hesitation when selecting forward or reverse gears.
- Low transmission oil pressure warning — Internal wear on the shaft splines or bearing surfaces leads to pump cavitation and pressure drops below 8 bar.
- Metallic debris in the oil pan — Flaking or scoring on the shaft surface contaminates the fluid, often accompanied by a whining noise from the pump area.
- Oil leaks near the front housing joint — Excessive shaft play damages the seal interface between the HOUSING REAR PART and the pump housing.

Frequently Asked Questions
Q: Can the 4657.354.058 pump shaft be used in a ZF WG180 transmission?
A: Yes, it is fully compatible with WG180 models provided the transmission uses the standard pump housing. Cross-reference your existing shaft length to confirm.
Q: What torque specification should I use for the retaining plate cap screws?
A: Tighten the M10 cap screws (0636100801) to 45 Nm and the M12 screws (0636100803) to 75 Nm using a thread-locking compound. Always replace the fixing plate (4656301148) if deformed.
Q: How do I identify shaft wear without disassembly?
A: Measure the axial play at the pump shaft spline end. Acceptable clearance is 0.05–0.15 mm. Play exceeding 0.25 mm indicates imminent failure and requires replacement of both the shaft and the associated housing sections.
