ZF 2093.088.023 T 7228 L | OEM Genuine Part

Overview

This OEM genuine ZF 2093.088.023 T 7228 L component is a precision-engineered internal gear or shaft assembly designed for heavy-duty construction machinery transmissions. It functions as a critical torque-transfer element within the planetary gear set, ensuring smooth power delivery from the engine to the differential. The SKU 2093.088.023 is specifically manufactured to ZF’s original tolerances, making it a direct replacement for worn units in high-stress environments like wheel loaders and graders. When installed alongside a 2093109001: DIFFERENTIAL, this part maintains the correct gear mesh and load distribution across the axle assembly.

Symptoms of Failure

• Intermittent gear slipping under load: When the 2093.088.023 wears, the transmission may momentarily lose drive torque during acceleration, particularly when climbing grades or moving heavy loads.
• Metallic grinding noise from the transmission housing: Worn splines or bearing surfaces produce a distinct high-pitched whine or grinding sound that intensifies with speed, often mistaken for differential failure.
• Oil contamination with metallic debris: Internal wear particles from this part will appear as silver or bronze flakes in the transmission fluid, often visible during routine oil changes or when inspecting the magnetic drain plug.
• Hard shifting or delayed engagement: A failing 2093.088.023 can cause erratic shift timing, as the control system compensates for lost torque capacity, leading to harsh clutch engagements.

Technical Specifications

Compatibility

This genuine ZF 2093.088.023 T 7228 L component is engineered for use in the following ZF transmission models commonly found in construction machinery: WG180, WG200, WG210, and WG250 series. It also fits select variants of the 4WG-200 and 6WG-250 powershift transmissions. For optimal assembly integrity, always pair this part with a new 0750117075: TAPER ROLLER BEARING to maintain correct preload, and verify the condition of the 2093209095: DIFFERENTIAL and 2093309071: DIFF.HOUSING for any wear or scoring before reassembly.

Frequently Asked Questions

Q: Can I reuse the old taper roller bearing when installing this 2093.088.023 part?
A: No. ZF engineering specifications require replacement of the 0750117075: TAPER ROLLER BEARING whenever the gear assembly is serviced. Reusing the bearing risks incorrect preload and premature failure of the new component.

Q: How do I confirm this part fits my WG200 transmission?
A: Verify your transmission serial number and check the existing part for the T 7228 L stamp. This 2093.088.023 is a direct fit for WG200, WG180, and WG210 models built after 2008. Always inspect the 2093309071: DIFF.HOUSING for cracks before installation.

Q: What torque specification should I use for the retaining nut?
A: Tighten the main shaft nut to 320 Nm (236 ft-lbs) with a thread-locking compound. After torquing, verify rotational freedom of the 2093109001: DIFFERENTIAL assembly—it should spin freely without binding.
