Typical example
Use Tooling (F) to measure the backlash for gear (5), gear (6), gear (7) and gear (8). Refer to Specifications, "Gear Group (Front)" for more information.
Lubricate each gear with clean lubricating engine oil.
If necessary, use Tooling (A) to rotate the crankshaft so that number one piston is at top dead center on the compression stroke. Refer to System Operation, Testing and Adjusting, "Finding Top Center Position for No.1 Piston" for the correct procedure. If necessary, use Tooling (D) in order to lock the crankshaft so that number one piston is at top dead center on the compression stroke.
Remove Tooling (D).
Failure to ensure that the crankshaft is positioned at 60 degrees after top dead center will result in interference between the pistons and the valves. Interference between the pistons and the valves will result in damage to the engine.
Use Tooling (A) to rotate the crankshaft in a clockwise direction and position the crankshaft at 60 degrees after top dead center.
