Overview
The ZF 0735.372.343 BUSH is a precision-engineered wear component designed for the BP210 and BP230 series transmissions. This OEM genuine part serves as a critical bearing surface within the gear train assembly, reducing friction between rotating shafts and the stationary housing. The bushing, identified by SKU 0735.372.343, is pressed into the transmission case to maintain precise shaft alignment and support radial loads during high-torque operation. It works in conjunction with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to ensure smooth power transfer through the drivetrain.
Symptoms of Failure
- Transmission oil seepage near the shaft seal area — When the 0735.372.343 bushing wears beyond tolerance, it allows excessive shaft play, compromising the seal lip and causing fluid to weep from the bell housing.
- Audible whining or grinding noise during gear engagement — A worn bushing creates metal-on-metal contact between the shaft and the HOUSING REAR PART, producing a distinct high-pitched sound under load.
- Vibration felt through the shift lever at highway speeds — Degraded bushing clearance allows the shaft to oscillate, transmitting harmonic vibrations into the cab that worsen with RPM increase.
- Delayed or harsh shifting between forward gears — Excessive radial movement from a worn bushing misaligns the clutch packs, causing erratic hydraulic pressure and sluggish engagement.

Compatibility
This bushing is engineered for ZF BP210 and BP230 series transmissions, commonly found in medium-duty trucks and construction equipment. It also fits select WG180 and WG200 models where the shaft journal dimensions match the 35mm inner diameter. The part interfaces directly with the CASE assembly and should be replaced whenever the transmission is overhauled to prevent premature wear of adjacent components.

Frequently Asked Questions
Q: Can I reuse the old bushing if it looks clean?
A: No. The 0735.372.343 bushing is a sacrificial wear item. Even if it appears undamaged, microscopic wear alters the clearance, leading to accelerated damage of the HOUS.FRONT SECT and shaft surfaces. Always replace during rebuilds.
Q: What torque should be applied to the cap screws securing the bushing?
A: The CAP SCREW (0636100801) requires 45 Nm for the BP210 series. Verify with the ZF service manual for your specific model variant.
Q: Does this bushing fit the ZF WG180 transmission?
A: Yes, when the WG180 uses the BP210-style shaft journal. Confirm your shaft diameter is 35mm before ordering. The bushing also mates with the CASE part number 4681298001 in these applications.
