TESTING AND ADJUSTING
DPS TRANSMISSION
Inspection
A good program of diagnosing and testing has
three basic steps.
1. Asking the operator
You can get the full story from the operator; he
wifi tell you how the system or the machine acted
when it began
to
fail, what was abnormal about
it.
Ask about how the machine was used, when
it was finally serviced. Remember, most failure
are usually traced to poor servicing er abuse of
the machine.
2. Checking the machine
(1) Check the oil level in the transmission.
(2) Check the transmission case and oil lines
for any sign of leaks.
(3) Check the inching pedal and transmission
control lever linkages for adjustment.
3. Operating the machine
Get on the machine and operate
it
for testing.
During the test, shift the transmission into all
gears, forward and reverse, and operate the inch
ing pedal. If the machine fails to start smoothly,
or if inching or shifting is hard, see Trouble
shooting, which follows.
Testing the clutches for slippage
(1) Start the engine, depress and lock the brake
pedal.
(2) Run the engine at maximum ~ and
move the transmission control lever into
forward 2nd speed position.
(3) If the engine stalls as soon as the transmi~
sion control lever is shifted, all clutches are
not slipping. If it does n& stall for more
than 3 seconds, or if it doe~s
not
stall
at
all,
any of the clutch (forward 2nd-speed) is
slipping.
