Removing bearing cover for intermediate shaft
NOTICE
Danger of timing chain jumping out of position
- Risk of engine damage
-> Never turn the engine at the crankshaft without a chain tensioner.
-> Never turn the crankshaft against the direction of rotation.
-> Always counter the sprockets when performing assembly work on them.
-> Make sure that nobody starts the engine or pushes the vehicle while in gear when the chain tensioner is removed. To prevent this, stick a warning note on the steering wheel or ignition lock.
Information
- For checking with the adjusting gauge, the timing adjustment must be correct.
Information
- To make it easier to remove the bearing cover, spray the sealing surface with anti-rust agent.
Information
- Remove bearing cover using special tool puller 9673. If this is not available, lever the bearing cover out carefully with two screwdrivers so as not to damage the sealing surfaces. Turning several times to the left and right loosens the bearing cover.
- After removing the bearing cover, do not press the threaded bolts of the intermediate shaft.
Bearing cover
Bearing cover with sealing ring
1. Lever out two green closure caps on pulley side of cylinder bank 1 - 3.
2. Turn the engine at the hexagon-head bolt (a/f 24) of the crankshaft belt pulley clockwise to overlapping TDC of cylinder bank 1 and fix it with special tool fixing pins 9595/1.
Fixing pulley
3. To check the camshaft adjustment, insert adjusting gauge 9686 for camshaft into the camshaft slots (pulley side) (inscription on gauge and small circular cut-outs point towards cylinder head cover). If the gauge cannot be inserted, rotate the crankshaft a further 360° and secure it again.
Cam slot position at overlapping TDC of cylinder 1
4. Unscrew two M6 x 12 hexagon-head bolts on the coolant pipe mount (Tiptronic) at cylinder side 1 - 3.
5. Remove primary chain tensioner (hexagon socket a/f 32).
Primary chain tensioner
6. Remove chain tensioner, cylinder bank 1 - 3 (hexagon socket a/f 32).
Chain tensioner, cylinders 1 - 3
7. Unscrew M8 hexagon collar nut on the housing of the intermediate shaft with special tool socket wrench 9110, while at the same time countering the slotted threaded pin on the intermediate shaft with a screwdriver.
Collar nut for bearing cover
8. Unscrew the three M6 x 20 hexagon-head bolts (coated) on the intermediate-shaft flange. Replace coated screws during installation and clean threaded bores.
9. Position special tool puller 9673 at the housing grooves and secure by turning the locking lever anti-clockwise.

10. Pull the slide hammer on the puller a number of times against the stop nuts while countering the tool at the same time with the other hand.
Removing bearing cover
11. If the puller is not available, lever the bearing cover out carefully using two screwdrivers (or angle screwdrivers), for example. Move the bearing cover frequently to the left and right to make the levering easier. Do not damage the sealing surfaces.

Installing bearing cover for intermediate shaft
Information
- Clean working area of bore for bearing cover and crankcase thoroughly using acetone or solvent naphtha.
Information
- Replace bearing cover or sealing ring for bearing cover -> 152355 Replacing sealing ring for intermediate shaft 15235550 Replacing sealing ring for bearing cover for intermediate shaft.
1. Before installing the new bearing cover, check the fitted bore (axial attachment surface, bore chamfers) on the crankcase for sharp edges and burrs. They should be removed with an oilstone or a polishing cloth. Remove any existing residue and clean the bore with a clean cloth soaked in solvent naphtha or acetone.
2. Grease fitted bore in crankcase and new bearing cover (with new sealing ring) with special grease Optimoly MP3 (available from Porsche Parts Service) and place bearing cover in position.
Information
- Replace collar nut M8 x 1 and coated M6 screws for bearing cover.
3. Position three new, coated M6 x 20 screws on the crankcase and pull in the bearing cover by screwing in the screws uniformly. Tighten screws => Tightening torque: 7.5 ftlb..
4. Position new M8 x 1 collar nut on the threaded pin of the intermediate shaft. Then tighten the nut using special tool socket wrench 9110. At the same time, counter with a screwdriver in the slotted threaded pin of the intermediate shaft. => Tightening torque: 9 ftlb.+0.5 ftlb.

5. Insert primary chain tensioner with new aluminium sealing ring (hexagon a/f 32) and tighten to the specified torque. => Tightening torque: 59 ftlb.
Primary chain tensioner
6. Insert chain tensioner for cylinder 1 - 3 with new aluminium sealing ring (hexagon a/f 32) and tighten to the specified torque. => Tightening torque: 59 ftlb.
Chain tensioner, cylinders 1 - 3
7. Fasten coolant pipes on cylinder side 1 - 3 with two M6 x 12 hexagon-head bolts. => Tightening torque: 7.5 ftlb.
8. Fit two new closure caps on cylinder head cover.
9. Pull fixing pin out of the crankshaft belt pulley.
