Key Features and Benefits

  • Premium material construction — high-strength steel that resists scoring, surface fatigue, and deflection
  • Precision machined — critical surfaces finished to tight tolerances for smooth rocker arm travel and stable valve operation
  • Improved durability under load — engineered for the heavy-load demands of C15, C16, and 3406E applications
  • Available as a single shaft or as a set of three
  • Backed by PDI's commitment to quality

Premium replacement rocker shaft engineered to restore valve train stability in CAT C15, C16, and 3406E engines. Ideal for rebuilds showing wear, scoring, or rocker movement. A worn shaft affects valve timing, valve lift consistency, rocker arm stability, and oiling efficiency long before it fully fails — installing a new shaft during a rebuild puts the valve train back on a smooth, correctly machined surface.

Please note: This rocker shaft is offered as a single shaft or as a set of three. Select the correct option at checkout for your application.

Common Wear Indicators — Check During Teardown

  • Scoring and groove wear where the rocker arms ride
  • Flat spots or uneven wear on the contact areas
  • Discoloration or heat spotting (blue, dark, or burnt areas)
  • Excessive side-to-side rocker movement
  • Oil starvation marks — dry patches or rough texture

If any of these conditions are present, the rocker shaft should be replaced to restore proper valve operation.
