CALCULATE THE THICKNESS OF THE ADJUSTMENT SHIM 

 

— — Put a platform benchmark on the clutch 

housing, and put a dial indicator with 
magnetic base on the benchmark. Set to 
zero when the pre fasten force is 1mm. 
Move the input shaft up and down 
according to the arrowhead direction, read 
and record the indication of the indicator. 

Main points: 

——During measuring, do not roll the output 

shaft otherwise the bearing will fall down 
and get wrong measuring value.

 

 

 

 

Disassembly: 
——For bearing pre fasten it needs thickness of 

the adjustment shim 0.20m; if the reading of 
the dial indicator is 0.30mm, and the 
thickness of the shim put in advance is 
0.65mm, then the thickness of the adjustment 
shim should be 0.20mm+0.30mm+0.65mm 
=1.15mm. 

——See the picture, screw off bearing plate bolt 

and take out output shaft. 

——Take out front bearing external ring of output 

shaft. 

——Take out the original adjustment shim.

Assembly: 

——Put the propriety adjustment shim to it right 

position and press output shaft front bearing 
external ring. Lubricate the bearing by gear 
oil and insert output shaft. Put on bearing 
plate and bolt fasten by 40Nm moment. 

——After changing one of  below parts: Clutch 

housing, transmission housing, differential 
bearing and differential housing, you need 
readjust the adjustment shim thickness for 
differential bearing pre fasten. 

 

 

Adjustment: 

——Press differential bearing external ring 

completely by special tool. 

——Press differential bearing external ring to the 

right position on transmission housing 
without any adjustment shim, and put 
differential assembly. Assemble transmission 
housing on to clutch housing and fasten the 
connecting bolt by 25Nm moment. 

 

 
Put a special tool on small axle shaft and put a dial indicator with magnetic base on the 
benchmark. Set the dial indicator to zero when the pre fasten force is 1mm. Move the 
differential assembly up and down from one side and record the indication of the indicator.   
Notice: during measuring, do not roll the differential assembly otherwise it will influence the 
accuracy. 
Calculate the adjustment shim thickness: 
For bearing pre fasten it needs thickness of the adjustment shim 0.40m; if the reading of the 
dial indicator is 0.90mm, then the thickness of the adjustment shim should be 
0.40mm+0.90mm=1.30mm. 
Disassemble the connecting bolt of differential housing and clutch housing, take out 
differential bearing external ring, and buildup the needed adjustment shim thickness by the 
least shim, put it to its right position on clutch and press differential bearing external ring 
completely. Assemble gasket and transmission housing, and fasten the fixing bolt by 25Nm 
moment.

DISASSEMBLY AND ASSEMBLY OF OIL SEAL AND OUTPUT FLANGE 

——The disassembly of this part can be carried 

out at the condition not break down the 
transmission assembly. 

Disassembly: 
— — Disassemble the connecting bolt between 

propeller s haft and flange, disassemble drive 
shaft and fix it on somewhere. 

 

——Remove flange cover by a special tool.

 

 

——Take out snap ring and dish washer.
