ZF 0730.003.458 SHIM for WG150 | OEM Genuine Part

Overview

The ZF 0730.003.458 SHIM is a precision-engineered adjustment component designed exclusively for the WG 150 series heavy-duty transmission. This OEM genuine part serves as a critical spacer within the planetary gearset assembly, ensuring correct axial clearance between rotating elements and stationary housings. By maintaining precise end-play tolerances, the shim prevents metal-on-metal contact that can lead to premature gear wear. The SKU 0730.003.458 is manufactured from high-tensile steel to withstand the extreme axial loads and thermal expansion cycles common in off-highway and industrial drivetrains. When installed alongside the TRANSMISSION HOUSING or the TRANSMISSION HOUSING, this shim guarantees that the output shaft assembly operates within factory-specified clearances.

Symptoms of Failure

When the ZF 0730.003.458 SHIM wears or deforms beyond tolerance, operators typically notice these four failure indicators:

• Excessive axial play in the output shaft – A loose or “clunking” sensation when shifting between forward and reverse, often accompanied by a dull metallic knock.
• Low-frequency gear whine under load – A deep, rhythmic noise that intensifies during acceleration, indicating misaligned planetary gears due to incorrect shim thickness.
• Intermittent oil seepage from the rear seal – Worn shims allow the shaft to shift, distorting the seal lip and causing slow, persistent fluid loss around the output flange.
• Premature bearing failure – Vibration analysis reveals increased radial play in the tapered roller bearings, often traced back to improper shim stack height.

Technical Specifications

Compatibility

This shim is engineered for the ZF WG 150 series transmission family. It is also compatible with the WG 180 and WG 200 models that share the same planetary carrier and output shaft geometry. The 0730.003.458 is frequently used in rebuild kits for WG 150, WG 180, and WG 200 units found in mobile cranes, concrete mixers, and heavy-duty dump trucks. For proper installation, always pair this shim with a new GROOVED STUD and verify the TYPE PLATE for the exact transmission serial number to confirm stack height requirements.
