Removal and installation the crankshaft cover from the gearbox side (Skoda Octavia 5E)

Pressing out the cover with the driving rotor

The gearbox is removed. Remove the flywheel.

Note: For better understanding, the procedure is shown with the engine removed.

Remove the intermediate plate from the rear cover of the crankshaft and the centering bushings "arrows". Rotate the crankshaft by the toothed pulley mounting bolt, set the crankshaft to the "TDC" position. Remove the oil pan. Remove the engine speed sensor "G28".



Remove bolts -1...6- securing the crankshaft cover.

Note: The cover is pressed off the crankshaft together with the timing rotor.

To press out, screw 3 M6x35 "arrows" screws into the crankshaft cover, alternately tightening each one by no more than 1/2 turn. Remove the cover with the timing rotor.

Pressing in the cover with the driving rotor

Note: The crankshaft cover with PTFE lip seal is supplied with a support ring for the working edge. Do not remove this ring before installation, as it will act as a mandrel during installation. After removing the cover with the timing rotor from the packaging, do not remove the rotor from the cover and do not rotate it relative to the cover. The correct installation position of the timing rotor is ensured by the lock of the "T10134" mounting device. The cover, lip seal and timing rotor form a single unit and should only be replaced as an assembly. The "T10134" mounting device is brought to the installation position relative to the crankshaft by means of a guide pin, which is inserted into the crankshaft hole.

Construction of the mounting device "T10134"

A. Lead screw flat


B. Hex nut
C. Body
D. Retainer
E. Hexagon socket head cap screw
F. Guide pin for diesel engines (black pen)
G. Guide pin for gasoline engines (red pen)
A. Installing the crankshaft cover with the timing rotor on the "T10134" device

Unscrew the hex nut "B" almost to the flats "A" of the lead screw shank. Clamp the mounting device "T10134" in a vice in the area of the clamping surface "A" of the lead screw. Pressing on the housing "C", move it down so that it rests against the hex nut "B" "arrow". The inner part and the housing of the device must be at the same level.



Remove the safety lock "arrow" from the new crankshaft cover.

Note: Do not remove or turn the timing rotor from the cover.

The locking hole "A" on the timing rotor "C" should be opposite the mark "B" on the crankshaft cover. Place the cover on a clean flat surface with the front (outer) side down.





Press the support ring "A" down "arrow" so that it rests against a flat surface.



Information published on the website (SkodaBook)

The top edge of the timing rotor and the front edge of the cover must be at the same level as the "arrow".



Place the cover with the front side on the "T10134" device so that the locking pin "B" enters the hole "A" of the timing rotor. The cover must lie flat on the mounting device.





While continuously pressing the cover and support ring "B" against the surface of the "T10134" fixture, tighten the two knurled head screws "A" so that the locking pin cannot slip out of the hole in the timing rotor. Only two knurled head screws are used - the upper and right ones, the left knurled head screw does not fit the threads on the crankshaft cover. When installing the crankshaft cover, the timing rotor must remain fixed in the mounting fixture at all times.

B. Installing the "T10134" device with a cover on the crankshaft flange

The crankshaft flange must be degreased. The engine is set to "TDC". Unscrew the hex nut "B" to the end of the lead screw. Press the lead screw of the "T10134" device in the "direction of the arrow" so that the hex nut "B" rests against the housing "A".





Align the flat side of the housing with the mating plane of the cylinder block on the oil pan side. Fasten the mounting device "T10134" to the crankshaft flange, for this, screw in the bolts with an internal hexagon "A" by approximately 5 thread turns.



Screw 2 M7 x 35 mm screws into the cylinder block -pos. A-, which will act as guides for the crankshaft cover.

C. Screwing the mounting device "T10134" to the crankshaft flange

Move the housing "C" by hand in the direction of the "arrow" until the support ring "B" rests against the crankshaft flange "A".

Warning! Risk of mixing up parts. Never insert the dowel pin for petrol engines (red handle) "F" into the threaded hole of the crankshaft.

Insert the dowel pin for the diesel engine (black head) "D" into the hole in the crankshaft, this ensures the final installation of the timing rotor. Tighten both Allen bolts of the mounting device by hand. Screw the Allen nut "E" onto the lead screw by hand until it fits against the body of the device "C".

D. Pressing the timing rotor onto the crankshaft flange using the mounting device "T10134"

Tighten the hex nut of the T10134 tool to 35 Nm. After tightening the hex nut to 35 Nm, there should be a small gap between the cylinder block and the flange.

E. Checking the mounting position of the timing rotor on the crankshaft

Unscrew the hex nut "E" to the end of the lead screw. Unscrew the bolts "A" from the cylinder block. Unscrew the knurled head screws "B" from the crankshaft cover, Unscrew the hexagon socket head cap screws. Remove the mounting device "T10134" from the crankshaft flange by unscrewing the hexagon socket head cap screws from the crankshaft flange. Remove the device "T10134", Remove the retaining ring.



Install the depth gauge "VAS 6082" on the crankshaft flange.



Measure the protrusion "A" of the crankshaft flange relative to the timing rotor "B". Nominal value: dimension "a" = 0.5 mm. If dimension "a" is too small, the timing rotor must be pressed in. If the specified value is reached, proceed with further installation.

F. Additional pressing of the master rotor

Secure the mounting device "T10134" "pos. A" to the crankshaft flange, tightening the Allen bolts by hand. Move the device toward the crankshaft cover by hand.



Screw the hex nut "E" onto the lead screw by hand until it touches the body of the device "C". Tighten the hex nut of the device "T10134" to a torque of 40 Nm. Check again for the correct position of the timing rotor on the crankshaft. If the dimension "a" is still too small, tighten the hex nut of the device "T10134" to a torque of 45 Nm. Check again for the correct position of the timing rotor on the crankshaft.

Assembly

Installation in reverse order. Install the oil pan. Install the intermediate plate. Install the flywheel.
