Installing the rear crankshaft oil seal
Note: Replace the rear crankshaft oil seal with a new one after each removal.
Caution: To ensure proper sealing, contact surfaces must be clean, dry and free of grease (avoid any fingerprints).

4. Install the cover (10) with the nut (11) (with the thread (12) of the nut facing out) of the crankshaft oil seal installation tool (Mot.1585).
5. Tighten the nut of the device so that the cover rests against the cylinder block.
6. Loosen the nut and remove the cover, protective element and guide from the crankshaft.
