1595Ford Fiesta Remake2C•16 Zetec engine in-car repair procedures4 Check the mountings to see if the rubber iscracked, hardened or separated from themetal components. Sometimes, the rubberwill split right down the centre.5 Check for relative movement between eachmounting’s brackets and the engine/transmission or body (use a large screwdriveror lever to attempt to move the mountings). Ifmovement is noted, lower the engine andcheck-tighten the mounting fasteners.Renewal6 The engine mountings can be removed ifthe weight of the engine/transmission issupported by one of the following alternativemethods.7 Either support the weight of the assemblyfrom underneath using a jack and a suitablepiece of wood between the jack saddle andthe sump or transmission (to preventdamage), or from above by attaching a hoistto the engine. A third method is to use asuitable support bar with end pieces whichwill engage in the water channel each side ofthe bonnet lid aperture. Using an adjustablehook and chain connected to the engine, theweight of the engine and transmission canthen be taken from the mountings.Engine front right-hand mounting8 This mounting consists of a two-piecebracket bolted to the inner wing panel,connected by the bonded-rubber mountingitself to a (Y-shaped) bracket, bolted (via thealternator mounting bracket) to the cylinderblock (see illustration).9 Unscrew the three bolts securing the frontright-hand mounting bracket to the alternatormounting bracket.10 Unscrew the bolts securing the mountingbracket to the inner wing panel and chassisrail and withdraw the mounting assembly.16.8 Engine front right-handmountingEngine rear right-hand mounting11 This mounting consists of the bondedrubbermounting secured to the inner wingpanel by a (horizontal) bolt, accessible fromwithin the wheel arch, and a (vertical) stud, theretaining nut of which is accessible from theengine compartment. The mounting is boltedto a bracket, which is in turn bolted to thecylinder block.12 Unbolt the mounting from the body byunscrewing first the single nut (and washer)immediately to the rear of the timing beltcover, then the bolt in the wheel arch.13 Unbolt the mounting from the cylinderblock bracket and withdraw the mountingassembly.Transmission bearer and mountings14 On XR2i models, remove the frontsuspension crossmember as described inChapter 10.15 Unscrew and remove the two nutssecuring the mountings (front and rear) to thetransmission bearer16 Support the transmission bearer, thenundo and remove the four retaining bolts fromthe floorpan, two at the front and two at therear, and lower the transmission bearer fromthe vehicle. Note plate fitment, as applicable,for reassembly.17 To remove the mountings from thetransmission, unscrew the upper bolt andlower stud (front mounting) or the three nuts(rear mounting) and withdraw the relevantmounting and bracket assembly from thetransmission.All mountings18 Refitting of all mountings is a reversal ofremoval. Make sure that the original sequenceof assembly of washers and plates ismaintained.19 Do not fully tighten any mounting boltsuntil they are all located. As the mountingbolts and nuts are tightened, check that themounting rubbers do not twist.17 Flywheel/driveplate -removal, inspection and3refittingRemoval1 Remove the transmission (see the relevantPart of Chapter 7).2 Where appropriate, remove the clutch(Chapter 6).3 Use a centre-punch or paint to makealignment marks on the flywheel/driveplateand crankshaft, to ensure correct alignmentduring refitting.4 Prevent the flywheel/driveplate from turningby locking the ring gear teeth, or by bolting astrap between the flywheel/driveplate and thecylinder block/crankcase. Slacken the boltsevenly until all are free.5 Remove each bolt in turn, and ensure thatnew replacements are obtained forreassembly; these bolts are subjected tosevere stresses, and so must be renewed,regardless of their apparent condition,whenever they are disturbed.6 Noting the reinforcing plate (automatictransmission models only), withdraw theflywheel/driveplate; do not drop it - it is veryheavy.Inspection7 Clean the flywheel/driveplate to removegrease and oil. Inspect the surface for cracks,rivet grooves, burned areas and score marks.Light scoring can be removed with emerycloth. Check for cracked and broken ring gearteeth. Lay the flywheel/driveplate on a flatsurface, and use a straight edge to check forwarpage.8 Clean and inspect the mating surfaces ofthe flywheel/driveplate and the crankshaft. Ifthe crankshaft left-hand seal is leaking, renewit (see Section 15) before refitting theflywheel/driveplate.9 While the flywheel/driveplate is removed,clean carefully its inboard (right-hand) face,particularly the recesses which serve as thereference points for the crankshaft speed/position sensor. Clean the sensor’s tip, andcheck that the sensor is securely fastened.Refitting10 On refitting, ensure that the engine/transmission adapter plate is in place (wherenecessary), then fit the flywheel/driveplate tothe crankshaft so that all bolt holes align - itwill fit only one way - check this using themarks made on removal. Do not forget thereinforcing plate (automatic transmissionmodels).11 Lock the flywheel/driveplate by themethod used on dismantling. Working in adiagonal sequence to tighten them evenly,and increasing to the final amount in two orthree stages, tighten the new bolts to thespecified torque wrench setting.12 The remainder of reassembly is thereverse of the removal procedure, referring tothe relevant text for details where required.
