ZF 2093.168.036 SPLITTER BOX | OEM Genuine Part

Overview

The ZF 2093.168.036 SPLITTER BOX is a critical power distribution component engineered for heavy-duty construction machinery transmissions. This OEM genuine part sits directly between the main gearbox and the range-change section, managing torque split and enabling precise gear selection under high load. The SKU 2093.168.036 is specifically designed to interface with the transmission housing assembly, ensuring seamless engagement of splitter gears during shifting operations. When paired with a robust 2093101016: HOUSING, this splitter box maintains oil flow integrity and structural alignment within the drivetrain.

Symptoms of Failure

• Delayed or harsh splitter engagement — Operators may notice a lag when shifting between high and low split ranges, often accompanied by grinding noises. This indicates worn internal gears or bearing surfaces within the 2093.168.036 unit.
• Oil seepage at the splitter box seam — Leaks typically develop where the splitter box mates with the 2093301030: TRANSMISSION HOUSING, causing gradual fluid loss and potential contamination of clutch packs.
• Intermittent gear slip under load — A failing splitter box may cause the transmission to momentarily lose torque during uphill climbs or heavy digging, a symptom often misdiagnosed as a mainshaft issue.
• Unusual vibration in neutral — Worn splitter bearings produce a low-frequency rumble when the vehicle is stationary with the engine running, signaling imminent internal failure.

Technical Specifications

Compatibility

This splitter box is engineered for ZF WG-series powershift transmissions commonly found in wheel loaders, graders, and heavy excavators. It directly fits the following models: WG180, WG200, WG210, and WG240. The 2093.168.036 unit also integrates with earlier ZF 4WG-200 and 6WG-310 variants. For proper installation, ensure the 0730365092: TYPE PLATE is correctly positioned to verify transmission model identification. Secure mounting requires the use of a 0631311009: GROOVED STUD to prevent rotational movement during operation.

Frequently Asked Questions

Q: How do I know if the 2093.168.036 splitter box is failing?
A: Listen for a distinct “clunk” when shifting between split ranges, especially under load. Also check for oil residue around the seam where the splitter box meets the transmission housing. If you see fluid weeping near the 0634801215: SEALING RING, replacement is likely needed.

Q: Can this splitter box be rebuilt, or must it be replaced entirely?
A: While internal bearings and seals can be serviced, the 2093.168.036 is typically replaced as a complete unit due to the precision machining of its gear sets. Always replace the 2093301021: GASKET and 0634303144: O-RING during installation to prevent leaks.

Q: Is the 2093.168.036 compatible with ZF WG200 transmissions built before 2005?
A: Yes, this splitter box fits all WG200 variants, including early models. However, verify that the 0730365092: TYPE PLATE matches your transmission’s serial number to confirm compatibility with the existing 0631311009: GROOVED STUD pattern.
