Zetec engine in-car repair procedures 2C•1313.13a Apply sealant (arrowed) as directedwhen refitting sump13.13b Checking alignment of sump withcylinder block/crankcase13.13c Sump-to-cylinder block/crankcasealignment shims1 Fitting points on sump 2 Shimthe transmission are absolutely clean andflat. Any shims found on removal of thesump must be refitted in their originallocations.b) Apply a thin film of suitable sealant (Fordrecommend Hylosil 102) to the junctionsof the cylinder block/crankcase with theoil pump and the crankshaft left-hand oilseal carrier. Without delay - the sumpbolts must be fully tightened within 10 to20 minutes of applying the sealant - offerup the sump and engine/transmissionlower adapter plate, and refit the bolts,tightening them lightly at first.c) Ensuring that the engine/transmissionlower adapter plate is correctly located,firmly press the sump against thetransmission, and tighten thetransmission-to-sump (ie, engine) bolts tothe specified torque wrench setting.d) Without disturbing the position of thesump, and working in a diagonalsequence from the centre outwards,tighten the sump bolts to the specifiedtorque wrench setting.e) Proceed to paragraph 14.13 If the sump is being refitted with theengine and transmission separated (in or outof the vehicle), proceed as follows:a) Apply a thin film of suitable sealant (Fordrecommend Hylosil 102) to the junctionsof the cylinder block/crankcase with theoil pump and the crankshaft left-hand oilseal carrier (see illustration). Without delay- the sump bolts must be fully tightenedwithin 10 to 20 minutes of applying thesealant - offer up the sump to the cylinderblock/crankcase, and insert the sumpbolts, tightening them lightly at first.b) Using a suitable straight edge to checkalignment across the flat-machined facesof each, move the sump as necessary sothat its left-hand face - including anyshims found on removal - is flush withthat of the cylinder block/crankcase (seeillustration). Without disturbing theposition of the sump, and working in adiagonal sequence from the centreoutwards, tighten the sump bolts to thespecified torque wrench setting.c) Check again that both faces are flushbefore proceeding; if necessary, unboltthe sump again, clean the matingsurfaces, and repeat the full procedure toensure that the sump is correctly aligned.d) If it is not possible to achieve exactalignment by moving the sump, shims areavailable in thicknesses of 0.25 mm(colour-coded yellow) or 0.50 mm (colourcodedblack) to eliminate the discrepancy(see illustration).14 The remainder of reassembly is thereverse of the removal procedure, noting thefollowing points.a) Tighten all fasteners to the torque wrenchsettings specified.b) Always renew any self-locking nutsdisturbed on removal.c) Refill the cooling system (see Chapter 1).d) Refill the engine with oil, rememberingthat you are advised to fit a new filter (seeChapter 1).e) Check for signs of oil or coolant leaksonce the engine has been restarted andwarmed-up to normal operatingtemperature.14 Oil pump - removal,inspection and refitting4RemovalNote: While this task is theoretically possiblewhen the engine is in place in the vehicle, inpractice, it requires so much preliminarydismantling, and is so difficult to carry out dueto the restricted access, that owners areadvised to remove the engine from the vehiclefirst. Note, however, that the oil pumppressure relief valve can be removed with theengine in situ - see paragraph 8.1 Remove the timing belt (see Section 8).2 Withdraw the crankshaft sprocket and thethrustwasher behind it, noting which wayround the thrustwasher is fitted (see Section9).3 Remove the sump (see Section 13).4 Undo the screws securing the oil pumppick-up/strainer pipe to the pump, thenunscrew the nut and withdraw the oil pumppick-up/strainer pipe. Discard the gasket.5 Unbolt the pump from the cylinderblock/crankcase (see illustration). Withdrawand discard the gasket, and remove thecrankshaft right-hand oil seal. Thoroughlyclean and degrease all components,particularly the mating surfaces of the pump,the sump, and the cylinder block/crankcase.Inspection6 Unscrew the Torx screws, and remove thepump cover plate; noting any identificationmarks on the rotors, withdraw the rotors (seeillustration).2C14.5 Unscrew bolts (arrowed) to removeoil pump14.6 Withdrawing oil pump inner rotor1595Ford Fiesta Remake
