ZF 2093.011.028 T 7226 L | OEM Genuine Part

Overview

This OEM genuine ZF 2093.011.028 T 7226 L 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 gears. Positioned deep inside the transmission housing, it directly supports the 2093109024: DIFFERENTIAL and works in concert with the 0750117075: TAPER ROLLER BEARING to maintain stable gear mesh under extreme torque loads. The SKU 2093.011.028 is a factory-spec replacement that restores original tolerances, preventing premature wear on adjacent components like the 2093209095: DIFFERENTIAL assembly.

Symptoms of Failure

When the ZF 2093.011.028 wears beyond specification, operators will notice distinct performance degradation. The most common failure indicators include:

• Transmission whining noise under load — A high-pitched metallic sound during acceleration or climbing indicates insufficient axial preload, often traced back to a worn spacer.
• Oil leaks near the differential housing — Deterioration of this component can misalign the 2093309071: DIFF.HOUSING seal surface, causing hydraulic fluid seepage.
• Gear slipping or delayed engagement — As clearance increases, the differential gears lose proper contact, leading to erratic power delivery and harsh shifting.
• Vibration in the driveline — Uneven wear on the thrust face creates rotational imbalance, felt as a low-frequency shudder through the chassis.

Technical Specifications

Compatibility

This genuine ZF 2093.011.028 is designed for use in the following ZF transmission families commonly found in construction machinery: WG180, WG200, WG210, and WG250 series. It is also compatible with select Ecomat 4HP and 6HP off-highway variants. Always verify the T 7226 L suffix against your transmission’s serial plate before ordering.

Frequently Asked Questions

Q: Can I reuse the old 2093.011.028 spacer if it looks clean?
A: No. This is a crush-type or precision shim component that deforms during initial torque-down. Reusing it will result in incorrect preload and rapid bearing failure. Always install a new OEM part.

Q: Will this part fit a ZF WG180 transmission from a 2015 wheel loader?
A: Yes, the T 7226 L variant is a common service part for WG180 series. However, cross-reference your transmission’s serial number with the ZF parts catalog to confirm the exact revision level.

Q: What tools are needed to replace the 2093.011.028?
A: Replacement requires a bearing puller set, a torque wrench capable of 250–350 Nm, and a dial indicator to measure end-play after installation. We recommend consulting the ZF service manual for your specific model.
