ZF 0730.001.515 SHIM for WG250 | OEM Genuine Part

Overview

The ZF 0730.001.515 SHIM is a precision-engineered adjustment component designed exclusively for the WG 250 series heavy-duty transmission. This OEM genuine part functions as a critical spacer within the clutch pack or planetary gear assembly, ensuring correct axial clearance and preload. By maintaining precise end-play tolerances, the 0730.001.515 shim prevents metal-on-metal contact between rotating elements and stationary housings. Installed directly against the TRANSMISSION HOUSING, this shim works in concert with the HOUSING and COVER to create a sealed, precisely spaced assembly. The SKU 0730.001.515 is laser-etched for traceability, guaranteeing authentic ZF metallurgy and dimensional accuracy.

Symptoms of Failure

• Transmission oil leaks at the housing joint: A worn or collapsed shim 0730.001.515 allows the COVER to shift, breaking the seal against the TRANSMISSION HOUSING. This causes fluid seepage around the mating surfaces, often mistaken for a gasket failure.
• Gear slipping under load: Incorrect clearance from a compressed shim reduces clutch pack clamping force. Operators report intermittent slipping in forward gears, especially during hill climbs or heavy hauling.
• Audible rattle or knocking from the bell housing: Excessive axial play due to a missing or degraded shim creates a distinct metallic chatter at idle, which disappears when the transmission is under torque.
• Premature bearing wear: Without the proper thickness of the 0730.001.515, thrust bearings experience uneven loading, leading to brinelling and eventual shaft misalignment.

Technical Specifications

Compatibility

This shim is specifically engineered for the ZF WG 250 series, but it also fits earlier WG 180 and WG 200 models where the clutch pack stack height requires fine adjustment. It is commonly used in rebuild kits for WG 220 and WG 240 transmissions found in municipal buses and medium-duty trucks. Always verify the stack height with a dial indicator before installation. The shim sits between the HOUSING and the COVER, secured by HEXAGON SCREW fasteners.
