Paccar MX-13 – Setting Engine to TDC

1. Use the special tool (1903018) to turn the crankshaft counterclockwise as seen from the distribution side.
This corresponds to the direction of rotation of the engine.

2. Position cylinders 1 and 6 at top dead center (TDC marking on vibration damper).
– Do not use valve setting marks 1/6 for this procedure.
– The TDC mark can also be read on the flywheel.
Repeat this procedure for cylinders 2/5 and 3/4, each time rotating the vibration damper 120 degrees (310 mm [12.2 in]).
– By turning the crankshaft 120° (310 mm [12.2 in]) clockwise as seen from the vibration damper side, cylinders 2 and 5 are in TDC position.
– By turning the crankshaft another 120° clockwise (310 mm [12.2 in]), cylinders 3 and 4 are in TDC position.
There is no marking on the vibration damper for the TDC position of cylinders 2/5 and 3/4.
