Skoda Workshop Service and Repair Manuals

Installing, set the timing l  Camshafts interlocked with the camshaft fixer/locators -T30094 (3458)-. l  Crankshaft locked into place by fixing screw -T30052 (3242)-. l  The camshaft sprockets loosened.   Note t  Also when carrying out repairs which necessitate taking the timing belt only off the camshaft sprockets, it is then necessary to set up the timing as follows. t  When rotating the camshaft, the crankshaft must not be positioned at TDC for any one cylinder. Risk of damaging valves and piston crowns. t  The camshaft fixer/locators -T30094 (3458)- must not be used as a counterholder.

–  First lay the timing belt on the crankshaft timing belt sprocket, the right camshaft sprocket and then on the tensioning pulley and the guide pulley as well as the water pump. –  Lay the timing belt on the left camshaft sprocket and fit it onto the camshaft. –  Screw in both camshaft sprockets until they can just still be turned and do not tilt.

–  Release the tensioning device 8 mm using the Allen key -arrow- and pull out the rig pin -T40011- for the hydraulic tensioner.

–  Tension the timing belt by turning in the -direction of the arrow- to 15 Nm using a torque wrench.

–  Tighten camshaft sprockets. Counterhold with -MP1-216 (3036)-, tightening torque 75 Nm.   Note The camshaft fixer/locators -T30094 (3458)- must not be used as a counterholder.

–  Screw the holder for the viscous fan on tightly: 1 -  45 Nm 2 -  10 Nm 3 -  22 Nm 4 -  10 Nm

–  Lock injection pump gear with rig pin -3359-.

–  Mount the drive wheel for the injection pump -1- in the middle position in the oblong holes. –  Tighten up the screws -arrows- handtight (the drive wheel on the camshaft sprocket should still be turnable). –  Lay the timing belt on the injection pump. Ensure that the marked direction of running is observed.

–  Tighten the timing belt. To do this turn the Allen key in an anti-clockwise direction -arrow- until the markings -1- cover each other. Finally tighten up the fixing nut using the special tool -3078-. t  Tightening torque: 36 Nm   Note The pointers -1- are designed blunt at the end depending on the model. –  Tighten the screws on the camshaft sprocket. t  Tightening torque: 22 Nm –  Remove the locking pin -3359-. –  Remove the camshaft fixer/locators -T30094 (3458)- from both cylinder heads. –  Remove the fixing screw -T30052 (3242)-. –  Turn crankshaft two turns in the direction of running of the engine until the crankshaft is again on TDC.

–  To act as a check screw the fixing screw -T30052 (3242)- back into the bore hole on the cylinder block.

–  Check the positions of the camshaft -T30094 (3458)- with the camshaft fixer/locators.   Note Repeat the adjustment procedure if the camshaft fixer/locators are not insertable. –  Remove the camshaft fixer/locators -T30094 (3458)- from both cylinder heads. –  Remove the fixing screw -T30052 (3242)-.

–  Check the tension of the timing belt for the injection pump. t  Markings -1- and -2- must stand opposite to each other.

–  Install the vibration dampener of the injection pump sprocket (screws -1-). t  Tightening torque: 22 Nm

–  Install the vibration damper. Take note of the interlocking lug -arrow- on the timing belt pulley. –  Screw in the plug of the TDC marking using a new O-ring into the cylinder block. –  Mount the vacuum pump onto the left cylinder head.

–  Mount the cap on the right cylinder head.   Note Always replace the cap. Further installation occurs in reverse order, while paying attention to the following: –  Install the V-ribbed belt → Chapter. –  Install the lock carrier → Body Work; Rep. Gr.50. –  Check the injection begin point dynamically and adjust → Vehicle diagnosis, testing and information system VAS 5051. Carry out with the VAS 5051 in the function “Targeted fault finding”, proceed with: 01-self-diagnosable systems / diesel direct injection and preheating system EDC 15M / function / ... .
