II. Transmission System 

System transmission route 

engine ----+torque converter(clutch) ----,..fluid(mechanical)  -----+-  transmission -----+  speed 

reducer-----+ differential----+ semi-axle  -----+-wheel system parts 

Referring to  diffe rent forklift models you purchase, models of the parts that form the 

transmission system are also different. Please pay attention to this point when you are doing 

maintenance. 

In  transmission  system,  transmission  and  fluid  torque  converter  (clutch)  matter  a  lot  in  the 

process of engine output power and torque are passed over driving wheel. Please get familiar with 

its function and working theory for correct repair and maintenance. 

2.1 Clutch 

2.1.2 Structure & Maintenance  ( Fig. 2-1 ) 

The clutch mainly consists of pressure plate, friction plate, clutch casing and release bearing. The 

pressure  plate is fixed on the fl

yw

heel of engine by  bolts.  Step on the clutch pedal and operate the 

release yoke to separate the friction plate and fl

yw

heel. 

The interval between the top  of clutch diaphragm and end face of release bearing is  2-3.Smm in the 

condition of clutch joint. Because of frequent speed up and steering, the friction plate wears quickly. 

Please often check this interval. 

2.1.3 Changing friction plate assembly 

A,  Step on clutch pedal to throw out the friction plate. 

B,  rotate the sliding screw on top of transmission counterclockwise to retract the driving shaft 

into transmission box.
