Stall Speed
Test
CAUTION:
. To prev€nt transmission damage, do not t6st stall speed for more than ro sgconds at a time.. Do not shift the levor while raising the engine speed.. Bo sule lo remove the pressure gauge betoro testing stall speed.
'1. Engage the parking brake, and block the front wheels.
2. Connect a tachometer to the engine, and start the engine.
3. Make sure the Ay'C switch is OFF.
4. After the engine has warmed up to normal operating temperature (the radiator fan comes on). shift into E position.
5. Fully depress the brake pedal and accelerator for 6 to g seconds, and note engine speed.
6. Allow two minutes for cooling, then repeat the test in @ and @ positions.
NOTE:
. Stall speed tests should be used for diagnostic purposes only,. Stall speed should be the same in o., E and E positions.
Stall Spsed RPM:
Specification: 2.700 rpm
Service Limit: 2,550 - 2,850 rDm

13. Measure the clearance between the clutch end plate
and top disc with a dial indicator' Zero the dial indi-
cator with the clutch end plate lowered and lift it up
to the snap ring. The distance that the clutch end
plate moves is the clearance between the clutch end
plate and top disc.
NOTE| Take measurements in at least three places,
and use the average as the actual clearance.
