Chery A18. Manual - part 125

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

——Remove flange cover by a special tool.

——Take out snap ring and dish washer.

——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.

——See the picture, fix the special tool on flange

by M8 bolt, rotate the shaft of special tool by
wrench to disassemble the output flange.
Take off spring seat and compression spring.

——Fasten the special tool on oil seal, rotate the

special tool threaded shaft by wrench until
screw off the oil seal.

Assembly:

——Use the right size oil seal and lubricate its lip.

Put it to its right position by special tool and
rotate the screw of the special tool make oil
seal to its true position.

——For the assembly of output flange, you can

use press or special tool press it into its
position, see the picture.

——Assemble dish washer and check if it is at its

right position

——Assemble snap ring and make sure it is inside

of snap ring groove.

——Assemble a new flange cover.

——Connect drive shaft and output flange

together, if it is necessary put lubricant to the
stipulated position.
