Chery A15. Manual — part 62

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.
