motor, (5). Motor support assembly, (6). fluid coupler 

2. CG958H loader adopts an independent cooling system (cooling fan control system) mainly 

consisting of pump, motor, motor support assembly, coupling flange, fluid coupler, etc., system 

cleanliness is controlled within Grade NAS1683 9. 

Features of cooling fan control system: 

(1). Better cooling effects on hydraulic oil and torque converting oil; 

(2). Cooling effects on hydraulic oil and torque converting oil are not affected even under loaded 

working conditions of the loader. 

System cleanliness is controlled within Grade NAS1683 9. 

II. Pump: CBQz-F532-AFΦL manufactured by Hefei Changyuan Hydraulics Co., Ltd. 

Position of pump: 

 

 

CBQz-F532-AfΦL gear oil pump adopts high strength aluminum alloy for pump casing, and uses 

many advanced technologies such as axial clearance floating compensation, radial equilibrium, DU 

self-lubrication, etc. It features high volumetric efficiency, high pressure, low noise, good vibration 

resistance and long service life. 

 

IMPORTANT 

 

Dismounting and servicing of gear pump by untrained maintenance staff is strictly 

prohibited.
