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.
