ZF 0730.110.007 SHIM | OEM Genuine Part

Overview

The ZF 0730.110.007 SHIM is a precision-engineered spacer component designed to establish critical axial clearances within the differential assembly of heavy-duty construction machinery transmissions. This OEM genuine part, identified by SKU 0730.110.007, sits between the differential housing and the bearing races to control end-play and preload. By maintaining exact tolerances, this shim prevents gear train misalignment and ensures that companion components like the 5838109012: DIFFERENTIAL operate within factory specifications. Without the correct shim thickness, the entire axle assembly risks accelerated wear and reduced torque transfer efficiency.

Symptoms of Failure

• Excessive differential bearing noise during turns: A worn or incorrect 0730.110.007 shim allows the 0750117075: TAPER ROLLER BEARING to shift, producing a distinct grinding or rumbling sound when the machine articulates.
• Oil seepage from the axle housing seal: Loss of axial preload causes the differential assembly to wobble, breaking the seal contact and leading to visible hydraulic fluid leaks around the housing joint.
• Intermittent gear slipping under load: When the shim compresses or fractures, the ring gear loses proper mesh with the pinion, resulting in momentary power loss during heavy digging or lifting operations.
• Vibration at the drive shaft: A collapsed shim creates uneven backlash, transmitting harmonic vibrations through the driveline that worsen at higher RPM.

Technical Specifications

Compatibility

This shim is engineered for use in ZF WG180, WG200, and WG310 series powershift transmissions commonly found in wheel loaders, graders, and telehandlers. It directly supports the 2093209023: DIFFERENTIAL assembly and interfaces with the 5838300626: DIFFERENTIAL HOUSING to set bearing preload. Always verify your transmission model number and existing shim stack thickness before ordering, as field adjustments may require stacking multiple shims.

Frequently Asked Questions

Q: Can I reuse the 0730.110.007 shim after disassembly?
A: ZF recommends replacing this shim whenever the differential is overhauled. The shim can deform plastically under preload, and reusing it may lead to incorrect bearing clearance and premature failure of the 0750117075: TAPER ROLLER BEARING.

Q: How do I select the correct shim thickness?
A: Measure the bearing preload gap using a dial indicator and feeler gauge. The 0730.110.007 is a 0.7 mm shim; stack multiple shims if needed to achieve the 0.05–0.15 mm end-play specified in the ZF service manual for the 5838300626: DIFFERENTIAL HOUSING.

Q: Will this shim fit a ZF WG180 transmission?
A: Yes, the 0730.110.007 is compatible with WG180, WG200, and WG310 models. Always cross-reference your differential part number—such as 5838109012: DIFFERENTIAL—to confirm the shim bore diameter matches your carrier.
