Note t
| Renew self-locking nuts and bolts when performing assembly work. |
t
| Renew bolts which are tightened to a specified angle as well as oil seals, gaskets and O-rings. |
t
| Hose connections and hoses for charge air system must be free of oil and grease before assembly. |
t
| To ensure that the charge air hoses can be properly secured at their connections, spray rust remover onto the worm thread of used hose clips before installing. |
t
| Fit all cable ties in the original positions when installing. |
Vehicles with manual gearbox: |
–
| When fitting a new clutch plate together with a used pressure plate (self-adjusting clutch), the adjuster ring in the pressure plate has to be reset by turning it back as far as it will go. If this is not done, the pressure plate will operate with reduced clamping force, causing clutch slip → Rep. Gr.30. |
Note t
| If the clutch plate is not being replaced, it is not necessary to reset the adjuster ring. |
t
| New SAC pressure plates are already pre-set accordingly, and do not have to be reset. |
–
| Clean input shaft splines and (in the case of used clutch plates) the hub splines. Remove corrosion and apply only a very thin coating of grease for clutch plate splines -G 000 100- to the splines. Do not lubricate guide sleeve. |
–
| Check that the clutch plate is properly centralised (only necessary if you have carried out other work on the clutch). |
–
| Check clutch release bearing for wear and make sure that plastic ring is securely seated; renew clutch release bearing if necessary → Rep. Gr.30. |
–
| A needle bearing must be fitted in the crankshaft on vehicles with manual gearbox; install needle bearing if not already fitted → Chapter. |
Vehicles with multitronic gearbox: |
–
| Clean input shaft splines and splines of damper unit on flywheel; remove corrosion and apply only a very thin coating of grease for clutch plate splines -G 000 100- to the splines. Remove any excess grease. |
–
| Check whether dowel sleeves for centring the engine/gearbox assembly are fitted in the cylinder block; install dowel sleeves if necessary. |
