Remove Timing Gears And Plate
start by:a) remove timing gear coverb) remove fuel injection pump and governor drive 1. Remove four bolts (2), plate (3) and idler gear (1).2. Use tooling (A) to remove camshaft gear (4).
Do not turn the crankshaft with camshaft gear removed. Damage can be caused to pistons and valves or both.

Heat camshaft gear (2) to a maximum temperature of 600°F (315°C) and install it on the camshaft. 5. Use tooling (A) and install the bearing in the idler gear. Install the bearing to a depth of .06 .02 in. (1.5 0.5 mm) below the rear face of the idler gear.6. Install idler gear, plate and bolts. Be sure No. 1 cylinder is at top center on compression stroke. Install idler gear so the "V" mark (4) on idler gear is in alignment with "V" mark on crankshaft gear. The "K" marks (3) of camshaft gear can be seen at outer edges of idler gear.end by:a) install fuel injection pump and governor driveb) install timing gear cover
