Titan 805-445 Thrust Washer

Part number 805-445 is a Thrust Washer specifically engineered for the Titan Impact 840 service, Impact 740-840, impact 740, and Iimpact 840 I and IA airless sprayer systems. These professional-grade units deliver up to 3300 PSI operating pressure for residential, commercial, and industrial painting applications. This thrust washer is a critical wear component installed within the gearbox assembly to absorb axial thrust loads and maintain proper gear alignment. It provides a low-friction bearing surface that prevents metal-to-metal contact between rotating gears and stationary housings, reducing heat generation and extending component life.

During motor replacement procedures, technicians must inspect the gears and thrust washer for damage or excessive wear. The thrust washer is located in the front gear box assembly and must be checked whenever the motor is removed. Proper lubrication with Lubriplate is essential during reassembly to ensure smooth operation and prevent premature wear.

This thrust washer is subjected to continuous high loads, vibration, and potential contamination. Failure modes include wear, deformation, and fatigue cracking. Symptoms of a worn thrust washer include unusual noise from the gearbox, excessive gear play, and metal particles in lubricant. Replacement with genuine 805-445 thrust washer restores proper gear clearance and ensures reliable operation of Impact series sprayers.
