Operation

This transmission has five forward gears and one reverse gear, which is achieved by three sets of 
synchronizers and two shafts (input shaft and output shaft). All forward gears use conventional engagement, 
and reverse gear uses a sliding idler gear device. 1st-2nd synchronizer is installed on the output shaft and 
3rd-4th and 5th synchronizers are installed on the input shaft. The transmission will engage with its 
corresponding gear hub separately when it is shifted to each different gear position, thus realizing the 
transmission of power. Drive gear of final drive, which is on the output shaft, rotates driven gear of final drive 
and differential assembly, thus propeller shaft is driven to turn wheels.

Daily Maintenance

Generally, it is not necessary to take special maintenance for transmission case. The commonest 
maintenance is to change transmission oil. Gear lubricant for QR525MHE series transmission case must be 
equivalent to GL-4 75W-90 grade or above. Applying incorrect lubricant will cause serious damage to the 
transmission. Never use engine lubricant instead of transmission case lubricant. Please note that the lubricant 
filling capacity is also strictly specified.

Filling method:

Park vehicle on service platform or lifter levelly without removing the transmission. Prepare a container to 
recover used lubricant. Remove the transmission drain plug, and then drain the used lubricant completely. Be 
sure to tighten the drain plug firmly after draining.
Loosen the retaining plug of transmission, add lubricant to QR525 transmission with a special filling device 
until the lubricant is flowing out from the retaining plug, and then tighten the retaining plug.
