Throttle Valve Cable/Linkage: Adjustments

BORG WARNER 66

DOWN-SHIFT CABLE

Pressure check and adjust

Service tools: Pressure gauge CBW 1C; gearbox adaptor CBW. 1C-5.

Fig. 76:

Check engine tune. i.e. cylinder compressions, spark plugs. ignition timing, carburetters.
Using a suitable Allen key, remove the blanking plug (1, Fig. 76) from the gearcase.


CAUTION: On later cars, a bracket is fitted between the gearbox and the rear mounting.
Access to the blanking plug is through the hole in the bracket and under no circumstances may the bracket be removed.

Connect the pressure gauge to the gearbox. using appropriate adaptor.

CAUTION: Do not overtighten adaptor.

Taking care to ensure that the hose is kept clear of the exhaust system. route the hose around the outside of the car and into the passenger's window.
Run the engine until it reaches normal operating temperature.
Chock the wheels and apply hand- and foot- brakes.
Select "D"; pressure gauge should read 3.85 to 5.3 kgf/cm2 (55 to 75 lbf./in2) at idling speed.
Increase engine speed by 500 rev/min, gauge should read 5.3 to 8.1 kgf/cm2 (75 to 115 lbf./in2).
There must be a difference of 1.4to 1.76 kgf/cm2 (20 to 25 lbf./in2) in the two readings taken.
The lower figure must not exceed 5.3 kgf/cm2 (75 lbf./in2).
If above readings are not obtained, proceed as follows.

WARNING: Engine must be switched off and selector lever in "N" before carrying out adjustment.

Fig. 77:

Slacken the locknut (1, Fig. 77) on the downshift cable. By means of abutment nut (2. Fig. 77) on the outer cable, adjust the length of the
cable to alter the pressure.

NOTE: Increasing the length of the cable causes an increase in pressure; decreasing the length of the cable causes a decrease in pressure. The ferrule crimped on the inner cable should be approximately 0.4 mm (0.010 in) from the threaded portion of the outer cable (dimension "A" Fig. 77).

When the pressure is correct. tighten the locknut.
Remove the pressure gauge and adaptor, refit the blanking plug and, it necessary. top-up the transmission fluid.

CAUTION: Do not overtighten the plug.

Road-test the car.
