NOTE: Force to depress decelerator pedal (3) should be 63 to 77.5 [N]. If the force is out of
specification replace decelerator pedal control cable (26) and check operation. If the system is still
operating improperly, loosen nut (10) and disconnect a spring enclosure (24) from the intermediate
lever (20). Remove control cable (27) from the bracket (25). Remove end plate of spring enclosure
(24). Remove nut (33), washer and cup (32). Remove end of the control cable (27) from the
bushing (29). Remove spring (28) and check the spring
free length for 336 [mm], replace
if damaged or worn. Install the spring (28) in to the spring enclosure (24). Install cup and washer
(32) with nut (33). Check “F” dimensions for 10.5 [mm] and “E” for 19.5 [mm], relocate link (31)
and tighten lock nut (30) to obtain these dimension if necessary. Reassemble end plate of
spring enclosure (24). Reassemble control cable (27) to the bracket (25), torque the nut (10)
to 60 to 80 [Nm]. Reassemble the spring enclosure (24) to the intermediate control lever (20).
Perform adjustment as described above step 2 to 9.
11. Reinstall bracket (25) to pod with bolts (11). Reconnect wire harness connector (18) to the
potentiometer (17).
Brake pedal adjustment
1. Depress brake pedal (4) to obtain gap “B” 6.0 [mm] between the pedal arm and instrument
panel console wall. In this position brake spool of the steering valve (Refer to SECTION 7E)
should be fully moved out. If the brake spool is not fully moved out, loosen lock nut (6) and
make adjustment of rod (5) with clevis (7). Tighten lock nut (6).
2. Press brake pedal (4) to the resist. Check if “C” gap 2 to 3 [mm] is obtained.
3. Release brake pedal (4) and check “A” dimension (between floor and pedal center top) which
should be 185 to 188 [mm]
Engine Running
1. With control lever (1) in the forward position (LO), check to make sure engine is running at
designated low idle speed 700 - 800 [RPM].
2. With control lever (1) in the rearmost position (HI), check to make sure engine is running
at designated high idle speed 2000 - 2200 [RPM].
3. If designated speed is not reached, check the wire harness and potentiometer resistances as
described below in ENGINE CONTROL POTENTIOMETER CIRCUIT CHECK-IN.
4. Place control lever (1) in the rearmost position (HI). Adjust decelerator pedal adjusting bolt (2)
so that when decelerator pedal (3) is pressed 40 [mm], specified decelerated engine
speed is obtained 1100 - 1200 [RPM]. Stop the engine.
ENGINE CONTROL POTENTIOMETER CIRCUIT CHECK-IN (electrical parts)
General
Before performing the potentiometer circuit check, turn key to the “ON” position. Check that there
are not throttle position sensor fault code(s) (refer to Troubleshooting Fault Codes in
Troubleshooting and Repair Manual Electronic Control System QSX15 Engines, Bulletin
No.3666259.
Inspect visually wire harness and connectors for damaged pin(s). Dry connector by using electrical
contact cleaner P/N 3824510.
