Engine/transmission mountings - inspection and renewal
In-car engine repair procedures / Engine/transmission mountings - inspection and renewal


General
1 The engine/transmission mountings seldom require attention, but broken or deteriorated mountings should be renewed immediately, or the added strain placed on the driveline components may cause damage or wear.

2 While separate mountings may be removed and refitted individually, if more than one is disturbed at a time - such as if the engine/transmission unit is removed from its mountings - they must be reassembled and their fasteners tightened in a strict sequence.

3 On reassembly, the weight of the engine/transmission unit must not be taken by the mountings until all are correctly aligned. Fitting the Ford service tool in place of the front mounting, tighten the engine/transmission mounting fasteners to their specified torque wrench settings, and in the sequence described in Part B of this Chapter, Section 4, paragraphs 49 and 50.

Inspection
4 During the check, the engine/transmission unit must be raised slightly, to remove its weight from the mountings.

5 Raise the front of the vehicle, and support it securely on axle stands. Position a jack under the sump, with a large block of wood between the jack head and the sump, then carefully raise the engine/transmission just enough to take the weight off the mountings.

Warning: DO NOT place any part of your body under the engine when it is supported only by a jack!

6 Check the mountings to see if the rubber is cracked, hardened or separated from the metal components. Sometimes the rubber will split right down the centre.

7 Check for relative movement between each mountings brackets and the engine/ transmission or body (use a large screwdriver or lever to attempt to move the mountings). If movement is noted, lower the engine and check-tighten the mounting fasteners.

Renewal
Front mounting
8 Unbolt the resonator support bracket from the engine compartment front crossmember, slacken the two clamp screws securing the resonator to the air mass meter and plenum chamber hoses, then swing the resonator up clear of the thermostat housing (see Chapter 4). Unbolt the pulse-air filter housing from the mounting bracket, then unfasten the bolts/nuts securing the mounting to the subframe, unscrew the centre bolt and withdraw the mounting; note the location of the wiring connector bracket. The mountings bracket can be unbolted from the transmission if required (see illustration).

9 On refitting, ensure that the mounting-totransmission bolts are securely tightened, then refit the mounting and wiring connector bracket. Tighten first the mounting-tosubframe bolts/nuts, noting that these are to be tightened in two stages to the final specified torque wrench setting. Finally tighten the mountings centre bolt, again to the specified torque wrench setting.

Right-hand mounting
10 Unscrew the nuts and withdraw the bracket; note that these nuts are self-locking, and must therefore be renewed whenever they are disturbed. Unbolt the mounting from the body (see illustration).

11 Where hydraulic-type mountings are fitted - there are only five nuts securing the bracket, and the mounting is clearly identifiable from its shape - take care never to tilt these more than 5 from the vertical (see illustration).

12 On refitting, renew the self-locking nuts, and tighten all fasteners to the torque wrench settings specified. When tightening the nuts, tighten first the four bracket-to-engine nuts, then release the hoist or jack to allow the engine/transmissions weight to rest on the mounting. Do not allow the mounting to twist as the last two of the nuts are tightened (see illustration).

Left-hand mounting
13 Unplugging the two electrical connectors, disconnecting the vacuum hose (where fitted) and disconnecting the crankcase breather hose from the cylinder head cover, remove the complete air cleaner assembly with the air mass meter, the resonator and the plenum chamber (see Chapter 4).

14 Unscrew the three nuts to release the mounting from the transmission, then unbolt it from the body (see illustration). Note that the nuts are self-locking, and must therefore be renewed whenever they are disturbed.

Unscrew the centre bolt to dismantle the mounting, if necessary to renew components.

Rear mounting
16 Where the vehicle is fitted with automatic transmission, a separate damper may be fitted beneath the subframe, which must be unbolted to reach the mountings fasteners (see illustration).

17 Unbolt the mounting from the subframe, then unscrew the mountings centre bolt. If required, unbolt the mountings bracket from the transmission (see illustrations).

18 On refitting, ensure that the mounting-totransmission bolts are securely tightened, then refit the mounting. Tighten first the mounting-to-subframe bolts, noting that these are to be tightened in two stages to the final specified torque wrench setting. Finally tighten the mountings centre bolt, again to the specified torque wrench setting.
