Throttle housing - removal and refitting
Note: During manufacture the throttle plate is adjusted so that it is fractionally open, to avoid the possibility of it jamming shut, and it must not be repositioned. Idle speed adjustment is provided for by means of a screw which, according to its setting, restricts the airflow through the air bypass channel in the throttle housing.

Removal
1 Disconnect the battery negative lead.
2 Slacken the retaining screw and detach the inlet air hose from the throttle housing.
3 Disconnect the accelerator cable at the housing linkage with reference to Section 4.
4 Disconnect the distributor vacuum hose and auxiliary air hose from the underside of the throttle housing.
5 Undo the four nuts and carefully withdraw the throttle housing from the manifold studs.
Refitting
6 Refitting is a reversal of removal, but ensure
that the mating faces are perfectly clean.
Renew the gaskets, one on each side of the insulator block, if necessary.
7 On completion adjust the idle speed as described in Chapter 1.

10 Slacken the hose clip and detach the air inlet hose from the inlet duct.
11 Undo the two bolts securing the inlet duct to the rocker cover slacken the throttle housing connecting hose clip and remove the inlet duct (see illustration).

12 Extract the retaining clip and disconnect the throttle cable end from the linkage ballstud.
13 Undo the two bolts and remove the throttle cable bracket from the throttle housing.
14 Disconnect the auxiliary air hose, then undo the four nuts and remove the throttle housing.
15 Do not remove the throttle position sensor from the throttle housing unless absolutely necessary. If it must be removed, mark its position for refitting and then have it accurately adjusted by a Ford dealer on completion. This will also be necessary if the sensor or throttle housing are renewed.
Refitting
16 Refitting is the reversal of removal, but
use a new gasket and ensure clean mating
faces. After refitting adjust the idle speed as
described in Chapter 1.
