Installation
24. Installation is carried out in the reverse order of removal. Install the drive chain so that the marks made earlier are aligned with the marks on the camshaft pulleys (arrows) (see figure 2.9 b). Replace the camshaft pulley mounting bolts. Lubricate the guide lever pin 21 and insert it into the cylinder block until it stops. When installing cover 28, lift the drive chain up so that no loop is formed between the crankshaft pulley and the chain. Lubricate the sealing surfaces with sealant. Make sure that no sealant gets into the oil hole 29 of the drive chain tensioner (see figure 2.9 g). Replace seal 27.
