ZF 2093.199.017 LOOSE PARTS | OEM Genuine Part

Overview

This OEM genuine ZF 2093.199.017 LOOSE PARTS kit is a critical service component designed for use within the internal valve body and clutch housing assemblies of heavy-duty ZF construction machinery transmissions. It functions as a collection of small but essential hardware—including retaining rings, pins, and spacers—that secure and position hydraulic control pistons and shift elements. The SKU 2093.199.017 is typically installed during a full transmission overhaul to replace worn or missing loose hardware that can cause internal misalignment. This part works in direct conjunction with the 2093101025: HOUSING and the 2093301031: TRANSMISSION HOUSING to maintain precise gear train geometry under extreme load.

Symptoms of Failure

• Intermittent gear slipping under load: When the loose hardware in this kit fatigues, clutch pack clearances increase, causing the transmission to slip during heavy digging or grading operations.
• Internal rattling or knocking noises: Worn retaining rings or spacers allow axial play in the piston assembly, producing a distinct metallic rattle at idle or during gear engagement.
• Delayed or harsh shifting: Misaligned loose parts can obstruct hydraulic fluid flow to the clutch packs, resulting in sluggish engagement or abrupt shifts that stress driveline components.
• Contaminated transmission fluid with metallic debris: As the loose parts wear, they generate fine metal particles that circulate through the system, often visible during oil changes or filter inspections.

Technical Specifications

Compatibility

This OEM loose parts kit is engineered for ZF’s WG series powershift transmissions commonly deployed in wheel loaders, dozers, and excavators. Based on the part type and housing interface, the 2093.199.017 is compatible with the following ZF transmission models: WG180, WG200, WG210, and WG310. It is also frequently used in the 4WG-200 and 6WG-310 variants. For proper installation, ensure the 0730365092: TYPE PLATE is referenced to confirm your specific transmission revision, and always replace the 4475280013: SCREW PLUG during reassembly to prevent fluid bypass.

Frequently Asked Questions

Q: Can the ZF 2093.199.017 loose parts kit be reused after disassembly?
A: No. ZF engineering specifications mandate that all components in this kit—including retaining rings and spacers—must be replaced with new OEM parts during any transmission rebuild to ensure proper clamping force and prevent premature failure.

Q: What is the typical labor time to install this kit in a WG200 transmission?
A: Installation of the 2093.199.017 loose parts kit is performed during a full transmission teardown and typically requires 4–6 hours of labor for an experienced technician, as it involves disassembling the valve body and clutch housing assemblies.

Q: Does this kit include the O-ring or gasket needed for reassembly?
A: No. The 2093.199.017 kit contains only loose hardware. You must order the 0634314235: O-RING and 2093301021: GASKET separately to complete the seal replacement.
