Overview
The ZF 0501.006.262 PUMP is a critical hydraulic component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part generates the precise oil flow and pressure required to actuate clutch packs, lubricate internal gears, and maintain thermal stability within the transmission housing. Positioned directly within the main pump cavity, it draws fluid from the sump and delivers it through the valve body. The SKU 0501.006.262 ensures an exact fit and factory-specified performance, eliminating the guesswork of aftermarket alternatives. When replacing this pump, always inspect the 2094301036: HOUSING for scoring or wear that could compromise seal integrity.
Symptoms of Failure
- Delayed or erratic gear engagement: A worn pump cannot build adequate hydraulic pressure, causing hesitation when shifting from neutral to drive or reverse.
- Low or fluctuating transmission fluid pressure: Dashboard warning lights or pressure gauge readings below specification indicate the pump is failing to maintain consistent flow.
- Audible whining or grinding noise from the transmission: Cavitation or worn pump gears produce a high-pitched sound, especially during cold starts or under load.
- Visible oil leaks around the pump mounting area: Deteriorated seals or a cracked 2094101012: TRANSMISSION HOUSING allow fluid to escape, leading to low oil levels and overheating.
