Fig. 3.3–64. Using the 2085 puller to remove the camshaft seal ring
To remove the sealing ring, use the 2085 puller (see Fig. 3.3–64). Unscrew the inner part of the puller six turns from the outer part of the puller and firmly fix both parts.
Place the puller on the camshaft and press firmly into the sealing ring. Unlock both parts of the puller and remove the sealing ring by rotating the inner part of the puller. Remove the sealing ring from the puller.
Clean the sealing ring installation area.
Lubricate the sealing lip and outer surface of the new O-ring with engine oil before installing it in place.

Install the intake camshaft in place so that tool 3458 can be installed into the end of the shaft (Fig. 3.3–67).
Fig. 3.3–68. Location and numbering of camshaft bearing caps
Install bearing caps 1 and 5 and secure them with bolts (Fig. 3.3–68).
Position the exhaust camshaft so that tool 3458 can be installed into the end of the shaft.
Install bearing caps 0 and 4 and secure them with bolts (see Fig. 3.3–68).
Recheck the position of the rocker arms and hydraulic lifters.
Clean the mating surfaces on the cylinder head and camshaft outer caps.
