Overview
The ZF 2093.298.063 TRANSMISSION HOUSING is a critical structural component within ZF’s heavy-duty powershift transmissions, serving as the rigid backbone that encloses and aligns the gear train, differential assembly, and hydraulic circuits. This OEM genuine part (SKU: 2093.298.063) is precision-machined to maintain exact bearing bores and oil passage tolerances, ensuring that torque is transferred smoothly from the engine to the final drives in construction machinery such as wheel loaders and graders. Without a sound housing, the entire transmission loses its geometric integrity, leading to misalignment and premature wear of internal components like the 2093109002: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.
Symptoms of Failure
When the ZF 2093.298.063 housing deteriorates, operators often notice oil leaks at the transmission case seam—a clear sign that the housing has developed stress cracks or porosity. Another common failure symptom is persistent gear slipping under load, which occurs when the housing’s bearing bores become ovalized, allowing shafts to shift out of alignment. You may also detect abnormal whining or grinding noises from the transmission, indicating that the housing is no longer supporting the 2093209095: DIFFERENTIAL and 2093309071: DIFF.HOUSING correctly. Finally, contaminated transmission fluid with metallic debris often points to housing wear that allows internal components to rub against the case walls.

Compatibility
This transmission housing is engineered for ZF’s WG series powershift transmissions commonly found in construction machinery. It is directly compatible with the ZF WG180 and ZF WG200 transmission models, which are used in articulated dump trucks, wheel loaders, and telehandlers. The housing also fits select variants of the ZF WG150 series, provided the internal differential and bearing configurations match. For precise fitment, always verify the housing casting numbers against your existing unit, especially when pairing it with the 2093109002: DIFFERENTIAL and 0750117075: TAPER ROLLER BEARING.

Frequently Asked Questions
Q: How can I tell if my ZF 2093.298.063 housing is cracked?
A: Inspect the housing for oil seepage around the bolt bosses and ribbed sections. A crack often appears as a dark, oily line; you can also use a dye penetrant test on the casting to confirm hairline fractures.
Q: Can I reuse the old taper roller bearings when replacing the housing?
A: No. Always install a new 0750117075: TAPER ROLLER BEARING with a fresh housing. Old bearings will have worn races that do not match the new housing’s bore tolerances, leading to premature failure.
Q: Is the 2093.298.063 housing interchangeable with the 2093.298.062 version?
A: No. The 2093.298.063 has a revised oil gallery layout and different dowel pin locations. Using the wrong housing can block lubrication to the 2093109002: DIFFERENTIAL and cause rapid overheating.
