Assembly and disassembly of timing belt and oil dipstick
Before disassembling the timing belt . Turn the camshaft gear and fit timing pin 8430.123 into its housing on the support
( see figure 20 ) so that it coincides with the hole that can be found on the shaft ( the pin must rest against the boss surface).
Loosen the belt tensioner and clamp it up high as shown, remove the timing belt (Fig. 21÷22) and the oil dipstick (Fig. 23) by
removing the 3 coupling screws.
Loosen the timing pulley fastening bolt so that it can turn freely on the shaft.
Drive shaft clamping
Disassemble the clutch, then fit clamping hub 5900.217 (together with component
8430.124) on the drive shaft and refer to the key for the clutch assembly (Fig. 25).
Tighten the hub using the washer and the nut with a 120 ÷ 140 Nm torque (Fig. 26).
Then fit timing pin 8430.124 and screw it onto the hub so that it coincides with the
hole on the clutch housing pan (Fig. 27).
