Using and maintenance of leaf spring
1. When vehicle runs for 200km and
500km during the beginning of
break -in period, check and tighten
U-type bolt on leaf spring with spec
鄄
ified torque under load bearing state.
2. After break-in period, tighten U-
type bolt on leaf spring with speci
鄄
fied torque when vehicle is fully
loaded. Do it also when leaf spring is
replaced or reset for running every
2000-3000km.
3. Tighten U - type bolt on leaf
spring with specified torque when ve
鄄
hicle is fully loaded for running for
2000km-3000km.
4. Check and tighten exposed bolts
and nuts of the suspension (with ve
鄄
hicle fully loaded) when doing class-
one maintenance. Check rubber
parts of the suspension, if the rubber
parts are worn greatly, replace them
instantly.
5. When doing class -two mainte
鄄
nance, carry out class -one items
and dismantle the leaf spring as well
as lubricating it, check the transverse
stabilizer rod at the same time.
6. When doing class -three mainte
鄄
nance, carry out class-two items and
dismantle all the rubber parts and

replace new ones.
7. When replacing leaf spring and
dismantling or assembling center
bolt, pay attention to the assembling
direction of front and rear steel plate.
When tightening leaf spring U -type
bolt and nut, screw it using well-dis
鄄
tributed force at first, then screw front
U -type nut according to specified
force moment and screw rear ones.
Using and inspection of shock ab 鄄
sorber:
1. Check the absorber for tempera 鄄
ture after running a certain length on
bad road surface (usually more than
10km) There is no resistance if the
temperature is low ( lower than air
temperature) and shock absorption
doesn't function. If one absorber has
much lower temperature than the
symmetrical one, the lower one's re
鄄
sistance is much more smaller. Low 鄄
er resistance result from lacking in oil
or from damage of some important
parts, and the absorber that lack in
resistance should be removed to in
鄄
spect.
2. Check the shock absorber for oil
leak if continuous abnormal vibration
is detected in running.Oil leak should
be dealt with in time, so that the
shock absorber can work normally.
3. Check absorber when maintaining
vehicle. To check absorber, stick up
it and hold its lower end by vise,
then pull and press it for several
times. Normally the resistance is
bigger when pulled, otherwise the
absorber is damaged or lack in oil.
Repair and replace parts and add
absorber oil in time to avoid serious
damage.
4. If it's necessary to replace ab
鄄
sorber rod, replace oil sealing at the
same time. If necessary, don't dis
鄄
mantle valve parts casually.
5. When doing class -three mainte
鄄
nance, dismantle and clean the ab 鄄
sorber,replace the absorber oil.Don't
forget cleaning when adding oil.
