Overview
The ZF 0501.316.495 BEARING BUSH is a precision-engineered component designed to reduce friction and support rotating shafts within the hydraulic control system of ZF WG200, WG92, and WG98 series transmissions. This OEM genuine part, identified by SKU 0501.316.495, sits directly inside the TRANSMISSION HOUSING where it acts as a sacrificial liner for the range selector mechanism. By maintaining tight clearances, it ensures consistent oil pressure delivery to the clutch packs and planetary gear sets. Replacing a worn bushing with this factory-spec component restores original tolerances and prevents metal-on-metal contact that can lead to catastrophic internal damage.
Symptoms of Failure
- Erratic gear engagement or delayed shifting – A worn 0501.316.495 bushing allows excessive shaft play, causing the RANGE SELECTOR to misalign and produce hesitation when shifting between forward and reverse.
- Low hydraulic pressure at the clutch packs – Clearance wear creates internal leakage paths, reducing oil volume to the clutches and resulting in soft shifts or transmission slipping under load.
- Metallic debris in the oil pan – As the bearing surface degrades, bronze or steel particles contaminate the fluid, often first noticed during routine filter changes or when inspecting the SUCTION TUBE screen.
- Whining or knocking noise from the transmission housing – Increased radial clearance causes the shaft to vibrate against the HOUSING, producing audible noise that worsens under load.

Compatibility
This bearing bush is engineered for the following ZF transmission models: WG180, WG200, WG92, and WG98 series. It is a direct fit for the range selector shaft bore in both 4-speed and 6-speed variants of these off-highway and commercial vehicle transmissions. Always verify your transmission serial number against the OEM parts catalog, as the PERIPHERALS kit may include updated bushing designs for later production runs.
