Overview
The ZF 2093.298.147 HOUSING is a critical structural component within the final drive assembly of heavy-duty construction machinery transmissions. This OEM genuine part serves as the rigid enclosure that supports the differential gears, bearings, and axle shafts, ensuring precise alignment under extreme torque loads. As the primary load-bearing shell, the housing (SKU: 2093.298.147) protects internal components from contamination while maintaining proper lubricant retention. It integrates directly with the 5838300626: DIFFERENTIAL HOUSING to form a sealed unit that transfers power from the transmission to the wheels.
Symptoms of Failure
- Persistent oil seepage around the axle flange: When the housing develops stress fractures or gasket surface corrosion, transmission fluid escapes, leading to low lubricant levels and eventual gear damage.
- Abnormal whining or grinding noise during turns: A warped or cracked housing misaligns the 0750117075: TAPER ROLLER BEARING, causing metal-on-metal contact that produces distinct audible feedback.
- Vibration under load at low speeds: Structural fatigue in the housing allows the 5838109012: DIFFERENTIAL to shift position, creating driveline shudder during acceleration or climbing.
- Metal particles in drained oil: Internal spalling or cracking of the housing bore surfaces releases debris that circulates through the 2093209023: DIFFERENTIAL assembly, accelerating wear on all rotating elements.

Compatibility
This housing is engineered for ZF WG-series powershift transmissions commonly deployed in wheel loaders, graders, and telehandlers. It is a direct fit for the WG180 and WG200 models, and also compatible with certain WG150 and WG250 variants where the final drive uses a bolt-on differential carrier. Always verify the housing flange pattern against your existing unit before installation.

Frequently Asked Questions
Q: Can I reuse the old gasket when installing a new 2093.298.147 housing?
A: No. Always replace the gasket and clean the mating surfaces thoroughly. A reused gasket will compromise the seal and lead to oil leaks within 50 operating hours.
Q: How do I confirm this housing fits my ZF WG180 transmission?
A: Measure the bolt hole spacing on your current housing. The 2093.298.147 uses an 8-bolt pattern on a 160 mm pitch circle diameter. If your unit matches, it is compatible.
Q: What torque specification should I use for the housing bolts?
A: Tighten the M12 bolts to 110 Nm (81 ft-lbs) in a crosswise sequence. Over-torquing can distort the housing bore and damage the taper roller bearing seats.
