through the threaded end of cylinder head rocker shaft
hole smooth load limit in the plate and the rocker shaft
hole, check rocker arm shaft load in place, can't interfere
with AB bolt holes, Align the right cover of the sealing
gasket and cylinder head with the mounting screw holes
and mount them in place, and then tighten the bolts;
7. Inject 3mL-5mL clean oil into the rocker arm oil
hole, the R surface of two rocker arms and the joint of
the camshaft.
Note:
1. When installing rocker arm shaft, the thread end of
rocker arm shaft is outward.
2. After the cylinder head is installed, turn the CAM,
and the CAM rocker arm should rotate flexibly without
clamping phenomenon.
3. Cylinder head right cover bolt fastening torque: 10 ~
14N·m,
4. When assembling the gasket on the right cover of the
cylinder head, the large hole should be consistent with
the oil passage hole on the right cover of the cylinder
head.
Installation of cylinder head
The installation steps of cylinder head are as follows:
1. Remove the old cylinder head gasket and install the
new cylinder head gasket, then install the positioning
pin, flanging bushing and rectangular ring.
2. Pull the trap to TDC, then attach the timing driven
sprocket to the timing chain. Timing sprocket O
stamped upward.
3. Install the cylinder head on the bolt A and B, then
load the cylinder head gasket, and then load the cylinder
head cover. Place the iron washer and copper washer on
the bolt A and B, then install the 4 cap nuts to tighten
the cylinder head cover on the bolt A and B, and tighten
them.
Note:
1. Dust and dregs should not be allowed to enter the
cylinder;
2. Fastening torque of A and B bolt nuts: 13 ~ 16N.m;
3. The copper washer is assembled on bolt B at the oil
passage.
4. Install the connecting screw of the cylinder head into
the connecting hole of the cylinder head and tighten the
fastening torque: 8 ~ 14N·m.
Adjust the timing sprocket with iron tag to align the
timing sprocket O mark with the cylinder head timing
mark notch, and align the magneto rotor timing scale
line with the timing mark on the left front cover, align
the timing sprocket hole with the camshaft screw hole,
load the timing bolt GB/T5783 M5×12, and then
tighten.
Timing adjustment method:
(1) Remove the large and small viewing hole cover on
