7.
Push the TV control lever on the transmission up against its internal stop with a firm force, approximately 22 N (5 lbs). Tighten the bolt on the
trunnion block. Do not relax force on ever until bolt is tightened
8.
Lower the vehicle and verify that the throttle lever is still against the minimum idle stop or throttle solenoid positioner stop. If not, repeat Steps 2
through 8.
Linkage Adjustment Using TV Control Pressure
NOTE: This procedure requires the use of TV Pressure Gauge with Hose (0-60 psi) T86L-70002-A or equivalent. The results of the adjustment
procedure depends on the accuracy of the pressure gauge.
A pressure gauge should be checked periodically (approximately once every six months) or when the following occurs:
1.
The needle will not return to 0 kPa (0 psi) under no pressure.
2.
The needle goes past 0 kPa (0 psi) (negative side) under no pressure.
3.
Bumping or dropping a pressure gauge.
The following procedure may be used to check and/ or adjust the throttle valve (TV) control linkage using the TV control pressure.
1.
Check/adjust the engine curb idle speed to specification required. Refer to the Enginel Emissions - manual for appropriate procedure. Ensure the
curb idle speed is set to specification with and without the throttle solenoid positioner (anti-diesel solenoid) energized, if so equipped.
2.
Attach Pressure Gauge (0-60 psi) with Hose T86L-70002-A and Adapter Fitting 080L-77001-A or equivalent, to the TV port on the transmission.
NOTE: If the service tool is not available, in order to avoid the exhaust system, obtain the following material and assemble as shown:
