Master cylinder
Frequently Asked Questions
Q: What does SKU 973201 master cylinder do in a forklift?
A: This master cylinder is the hydraulic control component that pressurizes fluid in the braking system. It converts mechanical pressure from the brake pedal into hydraulic pressure needed to engage the brake pads. Failure means loss of braking function, making the unit unsafe to operate.
Q: Which forklift brands and models use the 973201 master cylinder?
A: This master cylinder fits multiple OEM forklift models from Crown, Toyota, Raymond, and Hyster within standard load ranges. Verify your unit model and serial range before ordering, as master cylinder bore sizes vary by lift capacity and brake system design.
Q: What are the common failure symptoms of this master cylinder?
A: Soft or spongy brake pedal, brake fluid leaking from the cylinder body, inability to build brake pressure, or brake pedal sinking to the floor under load indicate internal seal failure or internal corrosion. Any of these symptoms requires immediate replacement.
Q: How long does a master cylinder typically last?
A: Under normal operating conditions, a quality master cylinder lasts 3 to 5 years. Heavy use, exposure to moisture, contaminated brake fluid, or lack of seal maintenance can reduce lifespan significantly. Regular brake fluid inspection and replacement every 2 years helps prevent premature failure.
Q: What is the bore diameter and mounting specification for the 973201?
A: Verify bore diameter and mounting flange type with your forklift service manual before ordering. Master cylinders come in standard sizes, but compatibility depends on your specific brake system design and load class. Incorrect bore size will prevent proper brake pressure.
