MU 0745903

Frequently Asked Questions

Q: What equipment does the MU 0745903 dust seal fit?
A: The MU 0745903 is a dust seal designed for Multiton 6600 series manual pallet jacks. This seal prevents dirt, moisture, and contamination from entering the hydraulic cylinder or pump assembly.

Q: What is the purpose of this dust seal in the hydraulic system?
A: The dust seal acts as an external barrier on the pump or cylinder rod, blocking dirt, moisture, and debris from contaminating the hydraulic fluid and internal sealing surfaces. Contamination is a primary cause of seal failure and premature system degradation.

Q: When should this dust seal be replaced?
A: Replace the dust seal if it is visibly torn, cracked, missing, or if hydraulic fluid leaks from the rod area of the cylinder. A damaged dust seal allows contaminants to enter the system and accelerates wear of internal seals.

Q: Can a damaged dust seal cause hydraulic system failure?
A: Yes. A compromised dust seal allows water and dirt to contaminate the hydraulic fluid, which degrades internal seal material and causes cylinder leakage, reduced lift speed, and eventual pump failure. Early replacement prevents costly downstream seal kit replacement.

Q: Is the MU 0745903 compatible with other Multiton models besides the 6600?
A: No. This dust seal is specified for Multiton 6600 series equipment only. Do not attempt to use this part on other Multiton models. Verify your equipment model before ordering.
