If a marking indicator is not supplied, sharpen an M6x50 and screw it into the hole for the marking indicator. igure 2 Mar ing indicator made of M50 bolt 4. Lubricate the transfer gears' plain bearings with oil. Install the transfer gears together with bea ring washers and hub. IMPO TNT! Check that the part numbers on the transfer gears, hubs and thrust washers face out ard and that the bearing washers face according to their marking ("Front"/"Rear" referring to engine's direction).

Check that the marking for TD on the camshaft stands between the markings on the camshaft's bearing cap and the flywheel at "0". NOTE! Rotate the flywheel in the engine's rotational direction. 8. Install the camshaft gear without vibration damper. Use spacer sleeves and two bolts. Install a mm 02 in drill bit in the hole on the cylinder head between the adjustable transfer gear and the camshaft gear. Check that the markings on the camshaft gear are on both sides of the drill bit.

Check that the line between the centre on the drill bit and the centre on the camshaft gear ends up between the markings on the camshaft gear. NOTE! Check the gear flank clearance according to the next step to prevent engine failures.

Check that the feele r gauges move against the same resistance when they are moved back and forth between the gear teeth. igure 10. Tighten the adjustable transfer gear according to step 1 Tightening torques cylinder block and then check that both feeler gauges move against the same resistance. Remove the feeler gauges. 11. Check the gear flank clearance between the adjustable transfer gear and the lower transfer gear by placing a dial gauge on the adjustable transfer gear. Hold the lower transfer gear at the same time as the adjustable tra nsfer gear is rotated back and forth.

Check that the gear flank clearance is within tolerance according to Transmission, general specifications .
