2106744 Genuine Paccar Camshaft Gear

The 2106744 camshaft gear is manufactured to Paccar factory specifications for transferring rotational motion and maintaining engine valve timing.

• Circular toothed construction allows the gear to engage with the applicable MX-13 timing-system components.
• Rotational input from the crankshaft is transferred through the timing system to drive the camshaft.
• Synchronized gear movement keeps camshaft position correctly referenced to crankshaft position.
• Controlled camshaft rotation determines when the intake valves operate during each engine cycle.
• Exhaust valve movement follows the same timed relationship established by the camshaft gear.
• Within the four-stroke cycle, the camshaft completes one revolution for every two crankshaft revolutions.
• Correct timing alignment prevents the operating errors that can allow piston and valve movement to interfere.
