ZF 0730.109.410 SHIM | OEM Genuine Part

Overview

This genuine OEM ZF 0730.109.410 SHIM is a precision-engineered component designed to establish exact axial clearances within heavy-duty construction machinery transmissions. Positioned between gear faces and bearing races, this shim compensates for manufacturing tolerances, ensuring optimal load distribution and preventing metal-to-metal contact. The SKU 0730.109.410 is critical for maintaining the correct preload on assemblies such as the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING, directly influencing gear mesh patterns and overall drivetrain longevity.

Symptoms of Failure

When the ZF 0730.109.410 shim wears or deforms, it compromises the transmission’s internal geometry. Watch for these specific failure indicators:

• Excessive gear backlash or “clunking” on direction change – A worn shim allows the 2093209023: DIFFERENTIAL to shift axially, creating audible play.
• Premature taper roller bearing failure – Incorrect shim thickness disrupts bearing preload, leading to overheating and spalling of the 0750117075: TAPER ROLLER BEARING.
• Oil leaks from axle housing seals – Axial movement from a collapsed shim can misalign the 5838300626: DIFFERENTIAL HOUSING, distorting seal contact surfaces.
• Vibration under load at low speeds – A degraded shim allows the differential carrier to wobble, transmitting harsh harmonics through the chassis.

Frequently Asked Questions

Q: Can I reuse the ZF 0730.109.410 shim during a transmission rebuild?
A: No. This shim is a single-use crush-type component. Reusing it will not restore proper preload and will lead to rapid bearing and gear failure. Always install a new OEM shim.

Q: How do I measure the correct shim thickness for my ZF WG200 transmission?
A: Use a depth micrometer to measure the bearing bore depth and the bearing protrusion. The shim thickness (0.40 mm for 0730.109.410) is then selected to achieve the specified preload torque. Consult your ZF service manual for exact calculation formulas.

Q: Will this shim fit the ZF ECCOM 6+6 axle?
A: Yes, the 0730.109.410 shim is dimensionally compatible with the differential carrier bearing pockets in ECCOM 4+4 and 6+6 axles. However, always verify the required shim count as multiple shims may be stacked to achieve final clearance.
