Titan 862-482 Engine Plate Screw

Part number 862-482 is an Engine Plate Screw specifically engineered for securing the engine mounting plate to the frame on compatible 0528925N_2000_4000, Hydra M, Hydra Pro Super, and Hydra M and Hydra Pro 2000_4000 series spray systems. These professional units include the Hydra M line of electric airless sprayers and the Hydra Pro series, both designed for high-volume commercial and industrial coating applications delivering up to 4000 PSI operating pressure. This critical fastener ensures that the engine or motor remains properly aligned with the pump drive system, maintaining correct belt tension and pulley alignment essential for efficient power transmission and long component life.

The engine plate screw is manufactured to exact engineering specifications including precise thread pitch, diameter, length, head style, and material grade. These specifications are carefully selected by equipment designers to provide the correct clamping force and vibration resistance required for the high-stress engine mounting application. The screw is typically installed with a lock washer and must be torqued to specific values to maintain preload under continuous operational vibration from the gas engine or electric motor. Proper torque prevents loosening while avoiding thread damage or fastener failure.

This fastener is subjected to extreme operational stresses including high torque loads during startup, continuous vibration throughout the operating cycle, and thermal expansion and contraction. Failure modes include stripped drive recesses from repeated service or improper tool use, thread damage from over-torquing or cross-threading, corrosion weakening the fastener, and stress fatigue at the head-shank junction. A damaged or missing engine plate screw can allow the engine to shift, causing belt misalignment, rapid belt wear, loss of power transmission, and potential damage to both engine and pump components. Replacement with genuine 862-482 engine plate screw restores proper engine mounting and ensures reliable operation.
