1.Press in V-belt at the illustrated position with about 100 N
(22 Ibs.) and measure deflection.
Standard value:
When belt tension is inspectedor readjusted
When new belt is installed
/ 9 - 11 mm (.35 - .43 in.)
I
’ 7 - 8.5 mm (.28 - .33 in.)
2.If the deflection is out of the standard values, adjust the belt
tension using the following procedure.
(1) Loosen the tension pulley’s securing bolts A and
B.(2) Mount the extension bar on the tension pulley.
(3) While increasing the tension of the V-belt with the
extension bar, retighten the tension pulley’s securing
bolts A and B in the order mentioned.
FLUID LEVEL CHECKM37FlAJ
1.Park the vehicle on a flat, level surface, start the engine, and
then turn the steering wheel several times to raise the
temperature of the fluid to approximately 50
- 60°C (122 -
140°F).
2.With the engine running, turn the wheel all the way to the
left and right several times.
3.Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine is
stopped, and while it is running. If the fluid level changes
considerably, air bleeding should be done.
FLUID REPLACEMENTM37FJAL1. Raise the front wheels on a jack, and then support them
with rigid racks.
2. Disconnect the return hose connection.
3. Connect a vinyl hose to the return hose, and drain the oil
into a container.
4. Disconnect the high-tension cable, and then while operat-
ing the starting motor intermittently, turn the steering
wheel all the way to the left and right several times to drain
all of the fluid.
Caution
Be careful not to position the high-tension cable nearthe carburetor or the delivery pipe.
5.Connect the return hoses securely, and then secure it with
the clip.
6.Fill the oil reservoir with the specified fluid up to the lower
position of the filter, and then bleed the air.
Specified fluid:MITSUBISHI PLUS ATF/Automatic
