Overview
This genuine OEM ZF 4108.012.113 P 3200 is a high-pressure hydraulic pump cartridge, a core component within the transmission’s hydraulic control unit. It is responsible for generating the precise oil flow and pressure required to actuate clutch packs and modulate gear shifts in heavy-duty construction machinery. Positioned inside the transmission sump, this pump cartridge directly governs the responsiveness and torque capacity of the entire driveline. The SKU 4108.012.113 identifies a specific revision of this pump, engineered for durability under continuous high-load cycles. When this cartridge degrades, the entire transmission system loses its ability to maintain consistent hydraulic pressure, leading to operational delays and potential internal damage.
Symptoms of Failure
Recognizing the early indicators of a failing pump cartridge can prevent catastrophic transmission failure. Watch for these specific signs:
- Delayed engagement or “shift hesitation” when moving from neutral to drive: A worn 4108.012.113 cartridge cannot build pressure quickly, causing a noticeable lag before the machine moves.
- Intermittent gear slipping under heavy load: When the pump cannot sustain high pressure, clutch packs slip, resulting in a loss of torque during digging or lifting operations.
- Persistent low transmission oil pressure warning: Even with correct fluid levels, a degraded pump cartridge will trigger dashboard alerts or diagnostic trouble codes (DTCs) for insufficient line pressure.
- Unusual whining or cavitation noise from the transmission housing: Air entrainment or worn internal clearances produce a distinct high-pitched sound, indicating the pump is struggling to prime or maintain flow.

Compatibility
This genuine ZF pump cartridge is designed for integration into the hydraulic control systems of specific ZF power shift transmissions commonly found in wheel loaders, telehandlers, and graders. It is a direct replacement for the following transmission series:
- ZF WG180 (all variants, including WG180/181)
- ZF WG200 (WG200/201 series)
- ZF 4WG-200 (4-speed versions)
- ZF 4WG-210 (select models with P 3200 pump designation)
Note: Always cross-reference your transmission’s serial number with the 4108.012.113 part number to confirm fitment, as internal pump port configurations may vary between early and late production runs.
