ZF 0730.106.813 THRUST WASHER | OEM Genuine Part

Overview

This ZF 0730.106.813 Thrust Washer is an OEM genuine component engineered to manage axial loads and maintain precise clearance within the planetary gear sets of heavy-duty construction machinery transmissions. Positioned between rotating shafts and stationary housings, this hardened steel washer prevents metal-on-metal contact that would otherwise lead to rapid wear and heat buildup. The SKU 0730.106.813 is specifically designed to fit ZF power shift transmissions, ensuring that gear alignment remains stable under the extreme torque demands of earthmoving equipment. When installed alongside a 4108101061 HOUSING, this thrust washer forms a critical boundary that protects the transmission’s internal architecture from premature failure.

Symptoms of Failure

• Erratic gear engagement and slipping under load — A worn 0730.106.813 thrust washer allows excessive end-play in the gear train, causing the transmission to slip out of gear when pushing heavy loads. This is a common symptom in ZF WG180 and WG200 units operating in wheel loaders.
• Metallic grinding noise during directional shifts — As the washer’s surface degrades, steel particles contaminate the transmission fluid, producing a distinct grinding sound when shifting from forward to reverse. This often accompanies damage to the 4108301339 INPUT SHAFT.
• Low hydraulic pressure readings at the clutch pack — Excessive axial clearance from a collapsed thrust washer reduces oil flow to the clutch packs, triggering pressure drop warnings on the machine’s dashboard. This failure mode frequently requires replacing the 4108306173 GASKET to reseal the assembly.
• Visible metal debris on the transmission dipstick or magnet — Flakes or shavings on the magnetic drain plug indicate the thrust washer has begun to disintegrate, often accompanied by scoring on the 4108201156 HOUSING mating surface.

Technical Specifications

Compatibility

This thrust washer is a direct replacement for ZF power shift transmissions commonly used in construction machinery, including the WG180, WG200, and WG210 series. It also fits select models of the 4WG-200 and 6WG-200 transmissions found in articulated dump trucks and crawler dozers. For proper installation, always verify that the 4108301304 BEARING COVER is free of burrs and that the mating surface is clean. This washer is not compatible with ZF car or truck manual transmissions.

Frequently Asked Questions

Q: Can I reuse the old thrust washer if it looks only slightly worn?
A: No. ZF thrust washers are designed as single-use components. Even minor surface wear alters the clearance tolerances, leading to accelerated damage to the 4108301339 INPUT SHAFT and adjacent bearings. Always install a new 0730.106.813 washer during any transmission rebuild.

Q: How do I know if the 0730.106.813 fits my ZF WG200 transmission?
A: This washer is standard in WG200, WG180, and WG210 models. Verify your transmission’s serial number against the 0730365280 TYPE PLATE location. If your unit uses a different planetary carrier, measure the inner diameter of the housing bore to confirm compatibility.

Q: What torque specification should I use when installing the bearing cover over this washer?
A: For the 4108301304 BEARING COVER, tighten the bolts to 45 Nm in a cross-pattern sequence. Always use a new 4108306173 GASKET to prevent oil bypass around the thrust washer.
