ZF 0730.150.557 SHIM | OEM Genuine Part

Overview

The ZF 0730.150.557 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances and preload settings within ZF heavy-duty transmission assemblies. This thin, hardened steel component sits between mating housing surfaces to compensate for manufacturing tolerances, ensuring correct gear mesh and bearing support. The SKU 0730.150.557 is specifically utilized in construction machinery transmissions where vibration resistance and load distribution are paramount. Proper shim selection prevents metal-to-metal contact and maintains the hydraulic integrity of the clutch packs. When paired with a TRANSMISSION HOUSING, this shim guarantees that the internal rotating assembly remains perfectly aligned under extreme torque loads.

Symptoms of Failure

• Excessive axial play in output shaft — When the 0730.150.557 shim compresses or fractures, you may detect noticeable fore-aft movement in the driveline flange, often accompanied by a dull clunking noise during direction changes.
• Intermittent gear slipping under load — Worn shim thickness alters clutch pack clearance, causing hydraulic pressure to bleed off. This manifests as momentary power loss when climbing grades or pushing heavy loads.
• Oil seepage at housing mating surfaces — A collapsed shim distorts the seal gap, forcing lubricant past the HOUSING joint. Look for dark, oily residue around the transmission bell housing or PTO cover.
• Elevated operating temperatures — Incorrect shim stack height increases bearing drag, generating excess heat that degrades transmission fluid and accelerates wear on adjacent components like the HOUSING.

Technical Specifications

Compatibility

This shim is integral to ZF’s modular transmission family used in wheel loaders, graders, and telehandlers. It is a direct fit for the WG180, WG200, and WG210 series, as well as the 4WG-200 and 6WG-200 powershift models. The 0730.150.557 also appears in certain Ecomat 2 and Ecomat 4 variants where the COVER assembly requires precise shimming. Always verify the shim stack height during rebuilds; using this OEM part alongside a new GASKET ensures factory-specified tolerances are restored.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Measure the axial endplay of the output shaft with a dial indicator. If clearance exceeds 0.20 mm, or if you observe oil weeping at the housing joint, the shim has likely compressed beyond service limits. Always replace in matched sets when rebuilding the transmission housing assembly.”

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “No. This is a single-use crush shim that deforms plastically during initial torque-down. Reusing it will result in incorrect preload and premature bearing failure. Always install a new OEM shim and verify stack height with a feeler gauge.”

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “Yes, this shim is standard in WG200, WG180, and WG210 series transmissions used in construction machinery. It sits between the main housing and the clutch cover. Cross-reference your transmission serial number to confirm compatibility with your specific housing variant.”
