Frequently Asked Questions
Q: Which lift truck models is the 91246-55300 compatible with?
A: The 91246-55300 is compatible with Mitsubishi models FBC20A2BC2, FBC25A2BC2, FBC25EA2BC3, FBC30A2BC3, FD20AF18A, FD20F18A, FD23AF18A, FD23F18A, FD25AF18A, FD25F18A, FD30AF14B, FD30F14B, FD35AAF26, FD35AF26, FG10AF25, FG10F25, FG15AF25, FG15F25, FG18AF25, FG20F17A, FG30F13C, and FG35AF13C. It is also compatible with Caterpillar electric lift truck models.
Q: What material is the 91246-55300 made from?
A: The 91246-55300 is constructed from cast iron, which provides excellent durability and thermal conductivity for brake system applications in electric lift trucks.
Q: What is the function of the 91246-55300 in the brake system?
A: The 91246-55300 is a hydraulic brake actuator that converts mechanical pedal force into hydraulic pressure to activate the service brake. It is a key component in the lift truck brake circuit and requires proper fluid maintenance for reliable operation.
Q: How can I confirm the 91246-55300 is the correct replacement for my lift truck?
A: Locate your equipment model number on the data plate and cross-reference it against the compatible model list. Verify that your existing master cylinder matches the bore size and configuration to ensure proper fitment.
Q: What type of seals does the 91246-55300 use?
A: The 91246-55300 uses nitrile (nbr) seals, which provide reliable performance with dot 3 and dot 4 brake fluids. These seals are standard in modern material handling equipment.
