Automatic Clutch Inspection (LT-A400/F)
B827H10206029
This vehicle is equipped with a centrifugal type
automatic clutch.
To insure proper performance and longevity of the clutch
assemblies it is essential that the clutches engage
smoothly and gradually. Before checking the initial
engagement and clutch lock-up two inspection checks
must be performed to thoroughly check the operation of
the drive train.
Initial Engagement Inspection
1) Warm up the engine.
2) Connect the tachometer or the multi-circuit tester
onto the spark plug high-tension cord (1).
3) Start the engine.
4) Shift the transfer range lever to the “High” position.
5) Slowly open the throttle and note the engine speed
(r/min) when the vehicle begins to move forward.
Special tool
: 09900–26006 (Engine tachometer (solar
cell type))
: 09900–25008 (Multi-circuit tester set)
Engagement speed
1 700 – 2 200 r/min
6) Disconnect the tachometer and install the frame front
cover.
Clutch “Lock-up” Inspection
Perform this inspection to determine if the clutch is
engaging fully and not slipping.
1) Warn up the engine.
2) Connect a tachometer onto the spark plug high-
tension code.
3) Start the engine.
4) Shift the transfer range lever to the “High” position.
5) Apply the front and rear brakes as firm as possible.
6) Fully open the throttle fully and note the maximum
engine speed sustained during the test cycle.
CAUTION
!
Do not apply full power for more than 5
seconds or damage to the clutch or engine
may occur.
Lock-up r/min
3 300 – 3 900 r/min
If the lock-up speed (r/min) does not coincide with
the standard range, inspect the following items for
any abnormalities.
Refer to “V-belt Type Continuously Variable
Automatic Transmission Removal and Installation in
Section 5A (Page 5A-7)”.
