Frequently Asked Questions
Q: What is the MO 12X3075 hydraulic pump piston designed for?
A: The MO 12X3075 is a precision-machined steel hydraulic pump piston assembly for Mobile MLX55 manual pallet jacks. It functions as the primary piston in the hydraulic lift system, enabling the lift and lower operations within standard pallet jack hydraulic circuits. The part is manufactured to OEM specifications for direct replacement fitment.
Q: Which pallet jack models are compatible with the MO 12X3075?
A: The MO 12X3075 fits Mobile MLX55 manual pallet jacks. Cross-reference part number ML12X3075 may also be found in some documentation. Always verify your equipment serial range and pump assembly configuration before ordering, as some Mobile models have variations in hydraulic circuit design.
Q: What material is the MO 12X3075 piston manufactured from?
A: The MO 12X3075 is precision-machined from hardened and ground steel. This material specification provides wear resistance and durability under repeated hydraulic pressure cycles typical in manual pallet jack lift operations. The hardened surface finish extends component lifespan in standard warehouse and dock environments.
Q: What symptoms indicate the MO 12X3075 piston needs replacement?
A: Common failure indicators include loss of lifting pressure, inability to reach full lift height, slow or weak lift response, or visible hydraulic fluid leakage at the pump assembly. Worn pistons cannot maintain proper seal contact, causing pressure loss in the hydraulic circuit. If the pump no longer builds pressure after checking fluid level, piston wear is likely.
Q: Is the MO 12X3075 a complete pump assembly or a single component?
A: The MO 12X3075 is a piston assembly component, not a complete pump unit. It is the moving element within the hydraulic pump mechanism. Depending on the type of failure, you may also need to order associated seals, check valves, or the complete pump assembly. Refer to your equipment manual or contact our parts team to confirm which components your repair requires.
