Timing case

To remove Operation 6-13
Note: Do not rotate the crankshaft when the idler gear is removed. If the crankshaft is rotated, top dead centre
(TDC) will have to be set on number 1 cylinder, see Operation 8-1.
1 Remove the alternator together with its mounting bracket and front support plate.
2 Remove the timing case cover, see Operation 6-1.
3 Rotate the crankshaft until the marked teeth of the crankshaft gear, the camshaft gear and the fuel pump
gear are all aligned with the idler gear. The marked teeth of the idler gear will not necessarily be aligned with
the marked teeth of the other gears because of the different speed of rotation of the idler gear.
4 Remove the gear for the fuel injection pump, see Operation 6-6 or Operation 6-8.
5 Remove the fuel injection pump, see Operation 11-14, Operation 11-16 or Operation 11-20.
6 Remove the idler gear, see Operation 6-4.
7 Remove the camshaft gear, see Operation 6-10.
8 Drain the lubricating oil and remove the sump, see Operation 10-4 or Operation 10-6.
9 Remove the 14 setscrews that retain the timing case to the cylinder block. Note the position of the setscrews
and any washers, to ensure a correct assembly later.
10 Remove the timing case and the joint, do not allow the idler gear hub to fall.
11 Release the two setscrews (A1) and remove the bridge piece (A2).
