Frequently Asked Questions
Q: What is the MU 39926 release pin used for?
A: The MU 39926 is a hydraulic release pin for manual pallet jack hand control assemblies. It functions as a dowel pin in the hydraulic linkage mechanism of Multiton manual pallet jacks, enabling operators to control lift and lower functions through hand-operated hydraulic control valves.
Q: What materials and specifications define the MU 39926?
A: The MU 39926 is manufactured from through-hardened alloy steel (SAE 5140 or equivalent) with a minimum Rockwell C38 hardness rating. Dimensions are 0.250 inch diameter and 1.18 inch length. This hardened construction resists wear and deformation under repeated hydraulic actuations.
Q: Which Multiton models are compatible with the MU 39926?
A: The MU 39926 fits Multiton manual pallet jack models TM, M, and J equipped with hand-operated hydraulic control systems. It is a direct replacement for prior Multiton hydraulic release linkage pins.
Q: What are the cross-reference or alternate part numbers for the MU 39926?
A: The MU 39926 may also be referenced as 39926, MU39926, or MT39926. These designations are equivalent and refer to the same release pin.
Q: Why is hardness important in a release pin?
A: The through-hardened design (SAE 5140, Rockwell C38 minimum) ensures the pin can withstand repeated compression, shear, and bending forces from hydraulic pressure cycles without permanent deformation. This hardness level maximizes service life and maintains precise fitment in the hydraulic linkage assembly.
Q: How should the MU 39926 be stored?
A: Store the release pin in a dry environment protected from moisture and corrosion. Keep it in its original packaging or in a sealed container to prevent rust and contamination. Avoid exposure to salt spray or harsh chemical environments.
