FAST Overhaul/Maintenance Repair Kit Specifically for Hydraulic Retarders FastFHB400
Classification and Components
1. Housing Mating Surfaces, Cylinder Head Gaskets, and Complete Seal Kits (Recommended for Overhauls)
Key components included: Main housing gaskets (stainless steel composite).
Gaskets: High-pressure seals for the mating surfaces of the split retarder housing; resistant to high temperatures and hydraulic fluid corrosion. Front/Rear oil seals (e.g., shaft-end seals): Prevent oil leakage from the high-speed rotating rotor shaft.
Complete set of high-temperature O-rings: Includes all sealing rings for internal oil and water circuit connections, ensuring no deformation or swelling under high-heat conditions.
2. Proportional Valve/Pneumatic Control Chamber Spool Repair Kit (Recommended for pneumatic circuit faults)
Includes key components:
Proportional valve spool seals: specialized U-cup seal for the pneumatic control piston and small-sized O-rings.
Return spring and dust seal: restores the valve's air pressure response sensitivity during operation.
3. Heat Exchanger (Water-Oil Cooler) Interface Repair Kit (Recommended for oil/water cross-leakage faults)
Includes key components: large, specially shaped gaskets for both ends of the heat exchanger and specialized high-temperature-resistant water hose seals.
Installation and Overhaul Technical Specifications
1. Strictly prohibit dry installation of rubber components: When reinstalling O-rings and oil seal lips included in the overhaul kit, thoroughly lubricate them first with clean, dedicated retarder oil or silicone grease. This prevents scratching the new rubber rings during press-fitting or twisting, which could otherwise lead to slow air or oil leaks.
2. Verify oil fill volume: After completing the overhaul, ensure that approximately 6.5L of genuine Fast dedicated hydraulic retarder oil is added. Insufficient oil can cause thermal degradation, while excessive oil leads to severe internal overheating of the retarder during operation.
