MU 0745904

Frequently Asked Questions

Q: What equipment does the MU 0745904 O-ring fit?
A: The MU 0745904 is an O-ring component designed for Multiton 6600 series manual pallet jacks. This part is used in pump and cylinder assemblies to provide static or dynamic sealing in pressurized hydraulic circuits.

Q: What is the function of this O-ring in the hydraulic system?
A: The O-ring creates a pressure-tight seal between mating metal surfaces in the pump, cylinder head, or valve assembly. It prevents hydraulic fluid from leaking between fitted components under system pressure.

Q: What symptoms indicate this O-ring needs replacement?
A: Replace this O-ring if hydraulic fluid leaks from connection points between pump and cylinder, if the system loses pressure, or if lift speed degrades. Visible cracks, hardening, or discoloration of the O-ring material also indicate replacement is needed.

Q: What material is this O-ring made from?
A: Genuine Multiton O-rings are manufactured from elastomer compounds formulated to resist hydraulic fluid degradation, temperature cycling, and pressure cycling. Material composition is optimized for OEM pump and cylinder tolerances.

Q: Is the MU 0745904 available as part of a complete seal kit?
A: Yes, this O-ring is typically included in complete seal kits such as the MU 07459010-TH or MU 07459019. However, the individual MU 0745904 O-ring can be ordered separately if only this component requires replacement.
