A: The 40777 is specifically engineered for Bishamon BS-55 series pallet jacks, while 40776 covers BS-55, BS-55A, and BS-65 models. Both kits use oil-resistant synthetic rubber and supersede part number 52103704. Confirm your exact model before ordering to select the correct seal kit.
Q: Which Bishamon models use the 40777 Bishamon Super Seal Kit?
A: The 40777 is the correct seal kit for Bishamon BS-55 manual pallet jacks. It provides complete hydraulic sealing for the pump cylinder on this model. Do not use on BS-65 or BS-55A models, which may have different bore specifications.
Q: What are the bore and rod diameter specifications for the 40777?
A: The 40777 is engineered for Bishamon BS-55 pump cylinders with a 1.00 inch bore and 0.563 inch rod diameter. These dimensions are critical for proper seal fit. If your cylinder bore or rod measurements differ, verify you have the correct model before proceeding with this kit.
