ZF 0730.102.062 SHIM for WG65 | OEM Genuine Part

Overview

The ZF 0730.102.062 SHIM is a precision-engineered adjustment component designed for the WG65 series of heavy-duty transmissions. This OEM genuine part, identified by SKU 0730.102.062, functions as a critical spacer within the planetary gearset assembly. It ensures correct axial clearance between rotating and stationary components, directly influencing gear mesh depth and bearing preload. When installed correctly, this shim prevents metal-to-metal contact and maintains the tight tolerances required for smooth power flow. It is typically positioned between the 2094101012: TRANSMISSION HOUSING and the main shaft assembly, acting as a sacrificial wear surface that protects more expensive transmission housings from scoring.

Symptoms of Failure

• Oil leaks from the bell housing area – A worn or collapsed shim allows the shaft to shift, breaking the seal between the 2094301036: HOUSING and the output flange, leading to visible drips during operation.
• Gear slipping under load – Excessive axial play from a degraded shim causes the clutch packs to lose hydraulic pressure, resulting in intermittent power loss when climbing grades or hauling heavy loads.
• Metallic grinding noise during shifts – As the shim thickness decreases, gear teeth contact patterns shift, producing a distinct high-pitched whine or grinding sound, particularly in lower gears.
• Vibration at highway speeds – Uneven shim wear creates imbalance in the rotating assembly, transmitting resonance through the 2094298057: HOUSING and into the chassis.

Technical Specifications

Compatibility

This shim is engineered specifically for the ZF WG65 series, which includes the WG65, WG80, WG100, WG120, WG150, WG180, and WG200 models. It is also compatible with select ZF Ecomat 4HP and 5HP variants that share the same planetary carrier design. The 0730.102.062 part is frequently replaced alongside the 2094301071: COVER during a full transmission overhaul, as both components experience similar wear cycles. Always verify the shim stack height using a depth micrometer when servicing the WG65 series.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Measure the axial play in the planetary gearset. If end float exceeds 0.15 mm, or if you observe oil leaks near the output flange combined with gear slipping, the shim has likely worn beyond its service limit.”

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “No. This is a single-use crush shim that deforms during initial torque application. Always install a new OEM shim (SKU 0730.102.062) to maintain proper bearing preload and prevent premature housing damage.”
