The crankshaft front cover may be removed with the engine 'in situ'.
1. Remove all 'V' belts, release crankshaft 'V' pulley bolt and conical washer and withdraw triple 'V' pulley.
2. Turn engine to timing position, with No. 1 cylinder (firing) at TDC using the timing marks and pointer on the flywheel rim and clutch housing with the camshaft pulley timing marks facing towards each other.
In this position, note or mark the position of the auxiliary shaft pulley.
3. Release timing belt eccentric tensioner lock nut, slacken belt tension, and slide belt off crankshaft toothed pulley.
4. Using special tool T000T0170A, and fitting the two bolts into the pulley finger- tight only, pull the toothed pulley off the crankshaft nose.
Timing pulley extraction tool T000T0170A5. Release the 6mm fixings securing the front cover to the front of the block, and withdraw cover.
carefully press out the old oil seal from the front cover.
The cylinder block and front housing should be thoroughly cleaned to remove all traces of the old gasket and remaining sealant.
From experience it is wise the crack test the front timing pulley to ensure there are no stress cracks running from the key-way to the external drive teeth.
To Replace:
1. Apply 'Wellseal' or alternative Loctite No.3 Forma Gasket to the outer diameter of a new oil seal.
With the aid of a simple press tool, insert the new seal into the front cover until flush with the rear face.
The press tool ensures the seal is true to the housing bore and no component distortion can take place.
2. Apply jointing compound to both mating faces, use a new gasket A907E0245Z.
Carefully fit the cover and oil seal over the crankshaft nose and into position.
If access permits, use special tool T000T0675 to protect the lip seal during fitment.
Torque tighten fixings to 10 - 11 Nm (7 - 8 lbf.ft) .
3. Refit remaining parts in reverse order to disassembly.
Apply anti-sieze compound to the timing pulley bore and the threads on the housing fasteners.
4. Re-install timing belt and set correct tension with the aid of a Burroughs gauge.
Torque tighten 'V' pulley bolt to 79 - 81 Nm . (58 - 60 lbf.ft).
