flanges with four sets of bolt and nut, and

(b)

Tighten the sets of bolt and nut according to the specified

torque.

Fastening torque

(74 5)Nm

Mount the center support bearing on the frame beam

(three joint type)

(a)

Use two mounting bolts to mount the center support

bearing on the frame beam and screw up them manually.

(b)

Check the bearing seat, which shall be vertical with the

drive shaft, and adjust the bearing seat when necessary.

(c)

Alignment of Front Wheel (Dr SL SK SY SJ)

Alignment of Front Wheel

(Dr SL SK SY SJ)

Inspection should be conducted for the following items to

remove the trouble

(a)

Check the tire abrasion and air inflation situation

Tire inflation pressure:

Front (220

0)kPa

Back (240

0)kPa

(b)

Check the front wheel bearing to see whether it is loose.

(c)

Check the front suspension to see whether it is loose.

(d)

Check the steering driving device to see whether it is

loose, and

(e)

Check the front vibration damper work to see whether it

is loose.

Measure the ground clearance of the chassis.

Chassis ground clearance:

295

SL SK

(255 2)mm

(310 2)mm

(295 1)mm

If the chassis ground clearance of the vehicle is sub-standard,

push down the body or raise it for a trial adjustment, if fails,

check the spring or suspension element to see whether they are

normal.

Remarks: adjust the chassis ground clearance to a specified

value before checking the Alignment of Front Wheel

parameters.

Mount on the four-wheel locating device.

The mount should be conducted according to the manufacturerís

instructions.
