Throttle cable
1. Inspection
a. Check whether the rubber sleeve of the right hand
handle and the throttle cable are damaged.
b. Check whether the rubber sleeve of the right hand
rotates smoothly and whether it can return automatically.
c. Hold the steering wheel with both hands and turn the
right hand to the right while rotating the rubber sleeve of the
right handle. Every time you turn a certain steering angle,
confirm whether the throttle can be reset normally. If you
can’t reset it, you need to lubricate the cable or the inside of
the right handle; or replace it with a new throttle cable or the
rubber sleeve of the right handle.
d. After starting the engine, turn the steering handle left
and right to ensure that the idling speed does not change
during the steering process, and then turn off the engine.
e. Rotate the right hand to check whether the rubber
sleeve inspection cable gap is within 2
～
4mm (0.1
～
0.2 in).
2. Adjust the throttle cable clearance
a. Fix the adjusting screw② with a 8# open-end wrench,
and then use a 10# open-end wrench to loosen the nut①
counterclockwise. Rotate the adjustment solenoid②
clockwise to reduce the free stroke, counterclockwise to
expand; adjust the gap to the specified value. After adjusting
the gap, tighten the nut①.
Torque: 3.8 N.m (0.4 kgf.m, 2.8 lbf.ft).
b. If the above adjustment fails to achieve the desired
effect, please refer to the description in "Remove the throttle
valve body assembly to clean up carbon deposits" to remove
the throttle valve body assembly. Use a 10# open-end
wrench to loosen the 2 nuts on the bracket to adjust. Torque:
3.0 N.m (0.3 kgf.m, 2.2 lbf.ft).
c. If the above two adjustments are invalid, replace the
throttle cable with a new one.
3. Lube door cable
If the rotation resistance is large and the bending of the
throttle cable and the loose strands of the wire core can be
eliminated, add a proper amount of lubricating oil, such as
sewing machine oil.
a. Remove 2 bolts
⑴
with a 5# inner hexagon, and move
the upper part of the switch away.
b. Use a syringe to draw a small amount of sewing machine
oil several times and inject it from the gap between the
throttle cap and the thread core, and turn the throttle while
injecting.
c. If the problem with high resistance cannot be solved
after lubrication, the throttle cable needs to be replaced.
●After adjusting the gap of the throttle cable, make sure that
the throttle handle can be automatically turned back to the
closed position. Do not adjust the cable to increase the
engine idling speed.
●After the adjustment, the engine idling speed cannot
increase when turning the front of the car.
●Do not use high-viscosity oil to lubricate the cable to
prevent excessive viscosity from affecting the free movement
of the cable.
