Frequently Asked Questions
Q: Which Multiton pallet jack models are compatible with the MU 21660 reservoir?
A: The MU 21660 hydraulic reservoir is used on Multiton TM, M, J, and S series manual pallet jack models. It serves as the main hydraulic fluid storage and air release component for the pump and linkage system. Confirm your model series before ordering.
Q: What are the cross-reference and alternate part numbers for the MU 21660?
A: The MU 21660 reservoir is also referenced as MU21660, MT21660, and 21660 on various documentation. All designations identify the same OEM component. For superseded versions, note that MU 21660-A is a replacement assembly for certain model configurations. Use MU 21660 when ordering current stock.
Q: What is the function of the MU 21660 reservoir in the hydraulic system?
A: The MU 21660 is the main hydraulic oil storage tank that supplies fluid to the pump mechanism and accumulates return flow from the linkage. It includes an air release vent and serves as a thermal heat sink. Adequate fluid level in the reservoir is essential for consistent lift performance.
Q: Has the MU 21660 been superseded by a newer part number?
A: The MU 21660 has been superseded by MU 21660-A for certain assembly configurations. Check your equipment documentation or contact us with your model and serial number to determine which version applies to your pallet jack. Do not assume interchangeability without verification.
Q: What maintenance does the MU 21660 reservoir require?
A: Inspect the reservoir monthly for cracks, dents, or corrosion. Check the fluid level on the sight gauge or by removing the filler plug. Maintain fluid at the proper level with the specified hydraulic oil type. Drain and refill the reservoir if fluid becomes discolored, cloudy, or contaminated. Replace the reservoir if internal corrosion or external damage compromises the seal.
