Generously lubricate the camshaft with oil in the bearing areas. Install the camshafts in their seats and turn them several times. Install the shafts so that both cams of the first cylinder on the two shafts are facing upwards.
Fig. 435. Individual elements of the camshaft: 1 - camshaft; 2 - camshaft bearing cap; 3 - washer; 4 - nut, 20 Nm; 5 - rear bearing cover; 6 - camshaft gear wheel; 7 - washer; 8 - bolt, 45 Nm
Using Fig. 435, put on bearing caps No.1, 3 and 5 and hand-tighten the nuts. Since the bearing caps are offset, check to see if they are seated correctly. To do this, using Fig. 406, determine if the caps have been put on correctly.
Tighten the nuts of the installed bearing caps alternately and crosswise in several passes to a tightening torque of 20 N·m. Make sure that the surface of the caps is located opposite the surface of the cylinder head.
Put on caps No.2 and No.4 and tighten the nuts. Tighten the nuts alternately and crosswise in several passes to a tightening torque of 20 N·m.
Take the camshaft seal and see which side the spring is on. The side with the spring should be facing inward. Lubricate the sealing surface (the rolling surface of the camshaft should also be lubricated). A pipe of the appropriate diameter can be used to install a new seal. The pipe must fully match the size of the outer part of the seal.

Push the seal straight in and tap it until its outer surface is completely in. The seal can also be installed in the manner shown in Fig. 439.
Install the camshaft timing gear onto the camshaft (don't forget about the wedge) and tighten the bolt with the washer. Keeping the camshaft stationary (for example, using an old toothed drive belt) and tighten the bolt to a torque of 80 Nm.
Perform the remaining work in the reverse order of the removal process.
