Overview
This genuine ZF 0501.313.803 END SHIM is a precision-engineered component designed to establish the correct axial clearance within the differential assembly of heavy-duty construction machinery transmissions. Positioned between the differential housing and the bearing race, this shim compensates for manufacturing tolerances and ensures optimal gear mesh alignment. The SKU 0501.313.803 is an OEM genuine part, guaranteeing exact material hardness and dimensional accuracy for long service life under extreme loads.
Symptoms of Failure
- Excessive differential bearing noise: A worn or collapsed end shim causes the 0750117075 TAPER ROLLER BEARING to lose preload, resulting in a low-frequency rumble or growl during turns.
- Oil leaks from the axle housing: When the shim thickness degrades, the 5838300626 DIFFERENTIAL HOUSING seal can become misaligned, allowing gear oil to seep past the seal lip.
- Intermittent gear slipping under load: Incorrect end play from a failed shim allows the 5838109012 DIFFERENTIAL to shift axially, causing momentary loss of torque transfer to the wheels.
- Metal debris in transmission oil: A fractured shim produces fine metallic particles that circulate through the system, accelerating wear on the 2093209023 DIFFERENTIAL gears.

Compatibility
This end shim is engineered for ZF WG series transmissions commonly used in wheel loaders, graders, and telehandlers. It directly fits the differential carrier assemblies of the following models: WG180, WG200, WG210, WG211, WG220, and WG230. Always verify the shim thickness requirement using the factory service manual for your specific transmission variant.

Frequently Asked Questions
Q: Can I reuse the 0501.313.803 end shim during a rebuild?
No. ZF specifies that this shim must be replaced whenever the differential is disassembled. The shim compresses plastically during initial torqueing and will not maintain correct preload if reused.
Q: How do I select the correct shim thickness for my WG200 transmission?
Measure the actual clearance between the bearing outer race and housing using a depth micrometer, then subtract the desired preload (typically 0.05–0.10 mm). The resulting value is the required shim thickness. ZF offers shims in 0.05 mm increments.
Q: Will this shim fit a ZF WG180 differential with the 5838300626 housing?
Yes. The 0501.313.803 is dimensionally identical for all WG180–WG230 series differentials when used with the standard 5838300626 DIFFERENTIAL HOUSING.
