Overview
The ZF 4657.183.349 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 210 series transmission. This genuine OEM part number 4657.183.349 contains the essential loose components required to secure and align the main transmission housing sections during rebuild or repair. It sits at the interface between the main casing and the front/rear housing sections, ensuring precise alignment and preventing vibration-induced wear. When paired with a new TRANSMISSION HOUSING, this kit restores factory tolerances to the entire assembly.
Symptoms of Failure
When the 4657.183.349 LOOSE PARTS wear out or are missing, operators typically experience transmission housing oil seepage at the mating flanges, particularly after heavy load cycles. A second common symptom is abnormal gear engagement noise during shifting, caused by slight housing misalignment. Third, you may notice increased vibration at the bell housing during acceleration, indicating that the loose parts are no longer dampening harmonic frequencies. Finally, intermittent loss of hydraulic pressure can occur if the fasteners in this kit loosen, allowing the housing sections to separate under torque.

Frequently Asked Questions
Q: Can I reuse the old loose parts from my WG210 if they look clean?
A: ZF recommends replacing the 4657.183.349 LOOSE PARTS kit whenever the transmission housing is separated. The fasteners in this kit are torque-to-yield and lose clamping force after initial installation, which can lead to oil leaks or misalignment if reused.
Q: Does this kit include the cap screws and pins shown in the related parts table?
A: No. The 4657.183.349 LOOSE PARTS kit contains only the specific loose hardware items (washers, spacers, and specialty bolts) unique to the WG210 series. Cap screws like 0636100801 and cylindrical pins like 0631306816 must be ordered separately if needed.
Q: How do I verify this part fits my specific transmission serial number?
A: Cross-reference your transmission model (e.g., WG210-5 or WG210-6) with the housing part numbers. If your unit uses the HOUS.FRONT SECT (4657201166) and HOUSING REAR PART (4657201168), this kit is the correct service replacement.
