ZF 2099.060.010 TRA 16 | OEM Genuine Part

Overview

The ZF 2099.060.010 TRA 16 is a critical internal component engineered for heavy-duty construction machinery transmissions. Specifically, this part functions as a precision-machined spacer or thrust element within the differential assembly, ensuring correct axial clearance and load distribution between rotating gear sets. As an OEM genuine ZF part, the SKU 2099.060.010 guarantees exact metallurgical composition and dimensional tolerances required for sustained performance under high torque conditions. It sits directly between the differential housing and the bevel gear stack, preventing metal-on-metal contact that would otherwise accelerate wear.

Symptoms of Failure

• Transmission whining noise under load: When the 2099.060.010 wears, axial play increases, causing gear teeth to misalign and produce a high-pitched whine during acceleration or climbing.
• Intermittent gear slipping in forward gears: Excessive clearance from a worn spacer allows the differential carrier to shift, leading to momentary loss of torque transfer and a “slipping” sensation.
• Metallic debris in transmission oil: As the part degrades, fine steel particles contaminate the lubricant, often visible during oil changes or on the magnetic drain plug.
• Oil seepage near differential housing: A worn 2099.060.010 can distort the housing seal surface, resulting in slow oil leaks around the axle flange.

Technical Specifications

Compatibility

This genuine ZF spacer is designed for use in the following transmission families: WG180, WG200, WG210, and WG250 series. It is also found in select Ecomat 5HP and 6HP off-highway variants used in wheel loaders, graders, and dump trucks. Always verify the part number against your transmission’s serial plate before installation.

During rebuild, this spacer is typically installed alongside the 2099109004 DIFFERENTIAL and the 0750117075 TAPER ROLLER BEARING to restore proper preload. The 2093209095 DIFFERENTIAL and 2093309071 DIFF.HOUSING are also direct neighbors in the assembly, requiring inspection for wear whenever the 2099.060.010 is replaced.
