Gear Train and Engine Timing For Detroit Diesel 60 Series Engines (11.1L, 12.7L, 14L)

The gear train of the Detroit Diesel Series 60 engine is a crucial system that synchronizes the movement of vital components. Its primary function is to transfer power from the crankshaft to other essential systems, such as the camshaft, fuel pump, and oil pump, ensuring precise timing for valve operation and fuel injection. The compact gear train design offers enhanced durability and efficient lubrication, contributing to the engine’s overall reliability and performance. Proper alignment and gear lash adjustment are critical for maintaining optimal performance and avoiding premature wear or failure.

Compact Gear Train Overview

The compact gear train is located at the front of the engine and operates within a fully enclosed housing. This design provides protection from contaminants and ensures the gears are continuously lubricated by oil splash. The gear train comprises the following components:

  • Crankshaft Timing Gear: Drives the bull gear and oil pump drive gear directly.
  • Bull Gear: Transfers motion from the crankshaft gear to the camshaft gear, air compressor, and accessory gears.
  • Camshaft Drive Gear: Controls the camshaft, which in turn operates the engine’s intake and exhaust valves, as well as the fuel injectors.
  • Idler Gear: Acts as an intermediary between the crankshaft gear and the camshaft gear, ensuring proper timing.
  • Oil Pump Drive Gear: Ensures the circulation of oil for lubrication and cooling.

Timing Mark Alignments

Accurate alignment of timing marks on the gear train is essential for proper engine operation. Misalignment can result in performance issues, including poor combustion, loss of power, or engine damage.

Steps for Aligning Timing Marks

  1. Initial Positioning:
    • Rotate the crankshaft using a ratchet or breaker bar until the timing marks on the crankshaft gear and bull gear align.
    • Ensure the camshaft timing mark aligns with the corresponding mark on the bull gear.
  2. Idler Gear Positioning:
    • Confirm the idler gear’s timing marks correspond with the timing marks on the crankshaft and camshaft gears.
    • Use a straightedge to verify that all marks are correctly aligned.
  3. Visual Verification:
    • Double-check the alignment of all marks. Use a flashlight to ensure marks are visible and clearly matched.
    • Rotate the crankshaft through two complete revolutions and verify that all marks realign perfectly.

Adjusting Gear Lash

Gear lash refers to the small clearance between mating gear teeth. Proper gear lash is vital for reducing noise, ensuring efficient operation, and preventing excessive wear or overheating. The acceptable gear lash range for the Detroit Diesel Series 60 engine is 0.051–0.229 mm (0.002–0.009 in.).

Importance of Gear Lash

  • Excessive Gear Lash: Causes increased vibration, gear noise, and potential damage to gear teeth.
  • Insufficient Gear Lash: Leads to overheating, accelerated wear, and binding of the gear train.

Measuring Gear Lash

  1. Prepare for Measurement:
    • Install a magnetic base dial indicator near the gear housing.
    • Position the indicator tip on the face of a gear tooth to detect movement.
  2. Measure Lash:
    • Hold the driven gear stationary and gently rock the driving gear back and forth.
    • Record the total movement displayed on the dial indicator.
  3. Check Multiple Positions:
    • Rotate the crankshaft to measure lash at four positions, spaced 90 degrees apart, for consistency.

Adjusting Gear Lash

  1. Shim Adjustment:
    • Add or remove shims between the gear housing and the engine block to modify the gear lash.
    • Adding shims increases lash, while removing shims decreases it.
  2. Recheck Measurements:
    • After adjustments, re-measure the lash to ensure it falls within the specified range of 0.051–0.229 mm (0.002–0.009 in.).
  3. Final Verification:
    • Rotate the crankshaft to ensure smooth operation and consistent gear movement without binding or excessive play.
