3695590 & 3695591 gear retainer is core fastening plate for timing gear system of Foton trucks with Cummins full-series diesel engines. Installed on engine camshaft and transmission gear shaft, it limits gear axial movement, keeps timing gear in accurate alignment during long-term engine operation.
This gear fixing plate solves typical engine faults including gear offset, timing deviation, abnormal knocking noise, gear tooth abrasion and power output instability caused by thin, deformed or softened old retainers, guarantee precise engine valve timing and stable power transmission for logistics transport vehicles.
Core Product Advantages
High carbon alloy steel raw material with integral quenching heat treatment, high surface hardness, strong compression and shear resistance, not easy to bend or crack under long-term high-speed gear vibration.
Ultra-precise flat surface grinding process, uniform flatness, fully fit gear end face without assembly gap, effectively block gear axial sliding and timing dislocation.
Standard integrated positioning hole layout, consistent hole spacing and outer dimension for both 3695590 and 3695591, perfectly match Cummins engine gear shaft assembly of Foton trucks.
Anti-oxidation anti-rust surface passivation treatment, resist high-temperature oil vapor, dust and condensate corrosion inside engine compartment, maintain stable mechanical performance for years.
Excellent fatigue resistance, withstand continuous reciprocating vibration generated by engine high-speed operation, no permanent deformation or looseness after long full-load driving.
Wide temperature adaptability, stable rigid performance from -40℃ ~ +130℃, no softening failure in summer high temperature or brittle crack in cold plateau environment.
Complete batch quality inspection including flatness test, hardness detection and vibration fatigue cycle test before delivery, consistent stable quality for repair shop replacement and fleet bulk procurement.
