Overview
This complete ZF 4657.053.007 3 WG 210 Powershift Transmission Assembly is a fully integrated unit designed for heavy-duty off-highway applications. As a core component of the WG 210 Series, this assembly manages torque distribution and gear ratio changes under load, ensuring smooth directional shifts in wheel loaders, graders, and industrial tractors. The SKU 4657.053.007 replaces the entire gear train and clutch pack assembly, making it a direct drop-in solution for rebuilds. It integrates with the TRANSMISSION HOUSING to form the main structural shell, while the HOUS.FRONT SECT and HOUSING REAR PART enclose the rotating elements. A CYLINDRICAL PIN aligns these housings during assembly, preventing misalignment under high torque loads.
Symptoms of Failure
- Delayed or harsh engagement: When the 3 WG 210 assembly wears, operators notice a pronounced lag when shifting from forward to reverse, often accompanied by a metallic clunk.
- Internal oil leakage: Worn seals within the unit cause transmission fluid to bypass the clutches, resulting in low line pressure and visible drips from the bell housing area.
- Gear slipping under load: As clutch packs degrade, the transmission slips out of gear when climbing grades or digging, causing a sudden loss of drive power.
- Unusual whining or grinding noises: Bearing wear inside the assembly produces a high-pitched whine that increases with engine RPM, indicating imminent failure of the planetary gear set.

Compatibility
This assembly is engineered for the ZF WG 210 Series, but its core architecture is shared across the WG family. It is directly compatible with WG 180, WG 200, and WG 210 transmissions found in 6–12 ton loaders and graders. The unit also fits select WG 211 variants when used with the correct FIXING PLATE and CAP SCREW kit. Always verify the bell housing pattern against your existing unit before installation.

Frequently Asked Questions
Q: Can the 4657.053.007 be installed without replacing the housing?
A: Yes, this is a complete unit that includes all internal rotating assemblies. However, we strongly recommend inspecting the TRANSMISSION HOUSING for cracks or wear, as a damaged housing will compromise the new assembly.
Q: What is the typical service life of this assembly in a wheel loader?
A: Under normal operating conditions with proper fluid maintenance, the 3 WG 210 assembly typically lasts 8,000–12,000 hours before clutch pack replacement is needed. Harsh applications like rock handling may reduce this interval.
Q: Does this part include the oil feed housing?
A: No. The OIL FEED.HOUSG. (part 4681301040) is a separate component that must be ordered if your original unit shows scoring or blockage in the lubrication passages.
