ZF 0730.001.795 SHIM | OEM Genuine Part

Overview

The ZF 0730.001.795 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within ZF powershift transmissions. This thin, hardened steel spacer sits between the transmission housing and bearing assemblies, ensuring correct preload and alignment of rotating shafts. By compensating for manufacturing tolerances, the SKU 0730.001.795 prevents gear train misalignment and maintains optimal load distribution across planetary gear sets. It is commonly used during rebuilds of construction machinery transmissions, where exacting end-play specifications must be restored to prevent premature bearing wear.

Symptoms of Failure

• Excessive axial play in output shaft: A worn or incorrectly selected 0730.001.795 shim allows the shaft to move longitudinally, causing irregular gear engagement and a knocking sound during load changes.
• Oil leaks from housing joints: When shim compression fails, the TRANSMISSION HOUSING can shift slightly, breaking the seal at mating surfaces and leading to external fluid seepage.
• Hard shifting or gear slipping under load: Loss of bearing preload due to shim wear reduces clutch pack clamping force, resulting in delayed engagement or torque loss during heavy operation.
• Vibration at specific RPM ranges: Misaligned shafts from degraded shim support create harmonic vibrations that resonate through the HOUSING and HOUSING assemblies.

Technical Specifications

Compatibility

This shim is engineered for ZF WG-series powershift transmissions commonly found in wheel loaders, dozers, and graders. It is directly compatible with the following transmission models:

• ZF WG180
• ZF WG200
• ZF WG210
• ZF WG310 (early variants)

Always verify stack height requirements during assembly. The shim works in conjunction with the COVER to establish final bearing preload.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “If you measure excessive axial play in the output shaft (over 0.15 mm) or notice oil weeping from the transmission housing joint, the shim may be worn. Always measure stack height during rebuilds and replace if compressed beyond specification.”

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “ZF recommends replacing all shims during a major overhaul. Reusing a shim can lead to incorrect preload because the material work-hardens and may have taken a set. Always install a new OEM shim for reliable clearance control.”
