- Under the collar of the two screwdrivers inserted in the places indicated by arrows in Fig. 93, and gently press it on the cylinder; - Cuff if necessary can be removed with a screwdriver at the same time without causing damage to the holder; - Thoroughly clean contact surfaces on the cover and the cylinder block; - Insert new seal into the holder, if it has been removed from it. The sealing lip of the new ring is displaced by 3 mm, so it will not work on the flange of the crankshaft to the same point as the old ring. The space between the sealing lip and the dust should be completed about 1 g of grease; - The sealing surface of the lid to put sealant and attach it to the cylinder block so that the alignment pins entered into the holes provided for them. Gently tap the top of the lid to make it denser lay. On HUNDRED company Mercedes-Benz used for this purpose a special clamping tool; - Tighten the two bottom screws, then the rest of 10 N ?� m; - Continue the work carried out in the reverse order of removal.
