Removal of clutch master cylinder, clutch cylinder
1. Use the No. 16 open-end wrench to remove the hose connecting
bleed bolt, use the cloth to cover the oil outlet of auxiliary pump
to avoid the splash of 0brake fluid; step on the clutch pedal for
several times to drain the clutch.
Cautions for installation of clutch operation device:
1. Installation of clutch hard pipe : Check the hard pipe for
deformation, check to see whether the curling at the port of
connection pipe is complete and without damage, if there is no
problem after confirmation, it can be installed and fixed in the
front wall clip and hard-tube clip.
2. Coat each rotary parts of peal with the lithium base grease.
3. Check the surface of clutch hoes, no surface cracking, oil leakage
and dog leg is allowed, use the split washer and spring clip to fix
the clutch hose on the support frame of car body.
4. Connect the joints of the general pump oil pipe and the general
2. Remove the split pin and cylinder pin connected the master
pump connecting fork to the pedal; use the No. 13 socket spanner
to remove two nuts Q32008 which is used to install the master
pump. Check the clutch master cylinder, replace the complete
master pump if the internal of master pump has the abnormal
noise and damage of leakage etc.
pump and sub pump according to the required tightening torque.
5. The air in the clutch oil path needs to be exhausted after filling
oil (except the vacuum filling): step on the clutch pedal after
fillingthe oil tank, when feeling difficult in stepping, use the
open-end wrench with specification of 11 to loosen the air bleed
plug screw to exhaust the air, then tighten the plug screw,
repeat the operation for several times. Tighten the air bleed
plug screw of the sub pump when there is no foam in the
flowing oil liquid. Supplement the oil of the oil tank to the
level between the Max and the Min.
