Frequently Asked Questions
Q: What is the MU 200178320 snap ring used for?
A: The MU 200178320 is an OEM snap ring designed specifically for hydraulic unit retention in Multiton TM 55 manual pallet jacks. It secures the hydraulic pump and motor assembly to the main frame and prevents axial separation during operation and transport. This is a structural retention component critical to pallet jack integrity.
Q: Which pallet jack models require this part?
A: The MU 200178320 is a direct fit for Multiton TM 55 series manual pallet jacks. It is not compatible with other Multiton series without confirming the hydraulic assembly bolt pattern and groove dimensions. This is a model-specific component designed only for TM 55 hydraulic unit assembly configuration.
Q: What is the material and coating on this snap ring?
A: The MU 200178320 is manufactured from carbon steel with an anti-corrosion phosphate coating. The phosphate finish prevents rust formation on the spring steel surface and extends service life in damp warehouse environments. The coating does not affect snap ring performance or fit in the groove.
Q: When should the MU 200178320 be replaced?
A: Replace the MU 200178320 if it shows visible cracks, has lost spring tension, or if the coating is severely compromised with active corrosion. If you notice hydraulic fluid leaking from the hydraulic unit or excessive vibration during operation, inspect the snap ring to ensure it remains fully seated. Replace it if groove damage prevents proper retention.
Q: Is this an exact OEM part for TM 55 hydraulic assemblies?
A: Yes, the MU 200178320 is the genuine Multiton OEM part for TM 55 hydraulic unit retention. It is manufactured to original specifications including groove diameter, spring tension, and phosphate coating thickness. Aftermarket substitutes may not provide the same retention reliability or durability.
