ZF 2094.306.019 WASHER | OEM Genuine Part

Overview

The ZF 2094.306.019 WASHER is a precision-engineered OEM genuine component designed to maintain axial clearance and distribute load within the planetary gear sets of heavy-duty construction machinery transmissions. This hardened steel washer sits between rotating shafts and stationary housings, preventing metal-on-metal contact that leads to premature wear. As a critical spacer element, the SKU 2094.306.019 ensures correct gear mesh alignment and oil film retention under high torque conditions. When paired with a properly torqued 2094104412 MAIN SHAFT or a 2094304054 MAIN SHAFT, this washer prevents end-play that would otherwise compromise transmission efficiency.

Symptoms of Failure

• Transmission oil leaks from shaft seals: A worn 2094.306.019 washer allows excessive axial movement, distorting the main shaft seal lip and causing fluid seepage around the output flange.
• Gear slipping under load in construction equipment: When this washer loses its precise thickness, the 2094106010 SHIFT SYSTEM cannot fully engage clutch packs, resulting in intermittent power loss during excavation or grading operations.
• Metallic grinding noise during gear changes: A collapsed washer permits the 2094206001 GEARSHIFT SHAFT to contact the housing, creating audible friction and accelerated debris generation in the oil sump.
• Increased vibration at the transmission housing: Uneven washer wear disrupts the rotational balance of the planetary carrier, transmitting harmonic vibrations through the driveline during steady-state operation.

Technical Specifications

Compatibility

This washer is engineered for ZF WG series powershift transmissions commonly used in wheel loaders, telehandlers, and graders. It is a direct fit for the WG180, WG200, and WG210 models, where it functions as a thrust washer between the sun gear and the reaction hub. The 2094.306.019 also appears in select WG150 and WG250 planetary drives. Always verify clearance with the 0630513070 SNAP RING and 0732040444 COMPRESSION SPRING during rebuild to ensure proper preload.

Frequently Asked Questions

Q: Can I reuse the 2094.306.019 washer during a transmission rebuild?
A: No. This washer is a single-use component due to its case-hardened surface. Reusing it risks axial clearance deviation and subsequent seal failure. Always install a new OEM genuine washer with every main shaft replacement.

Q: How do I measure if my current washer is worn?
A: Use a micrometer to check thickness at three points around the circumference. If any measurement is below 2.45 mm, or if you observe a polished concave wear pattern, replace the washer immediately to prevent damage to the 2094106010 SHIFT SYSTEM components.

Q: Does this washer require lubrication during installation?
A: Yes. Coat both faces with ZF-approved assembly grease or clean transmission oil before fitting. This prevents galling during initial rotation and ensures the 2094304054 MAIN SHAFT seats correctly against the thrust face.
