Blog Article


The starter motor for the 1958 Allis Chalmers Model D 226 motor grader is a robust mechanical component designed to initiate engine operation in heavy-duty construction equipment. The Model D 226, equipped with a 226 cubic-inch (3.7L) inline-six gasoline engine, requires a durable starter capable of withstanding the vibrations and demands of industrial use.

Design and Industrial Specifications


The starter motor for the 1958 Allis Chalmers Model D 226 features:

 

  • High-Torque DC Motor: Engineered to crank the large-displacement inline-six engine, operating on a 6-volt electrical system (common in 1950s machinery).

  • Mechanical Solenoid: A heavy-duty solenoid integrated into the starter housing, engaging the drive gear with the engine’s flywheel when triggered by the ignition switch.

  • Cast Iron Construction: Rugged housing and steel gears to withstand continuous use in construction environments, with minimal maintenance requirements.

  • Flywheel Compatibility: Designed for the 226 motor’s 13-tooth pinion gear and 154-tooth flywheel, ensuring precise meshing during startup.


Placement and Installation


On the 1958 Model D 226 motor grader:

 

  1. Location: The starter is mounted on the lower starboard side of the engine block, adjacent to the flywheel housing, accessible via the equipment’s engine compartment.

  2. Wiring:

    • Connect the positive battery cable to the solenoid’s main terminal (marked “B” or “BAT”).

    • Attach the ignition switch wire to the solenoid’s control terminal (marked “S” or “IGN”).



  3. Mounting: Secured with two heavy-duty bolts, torquing to Allis Chalmers’ specifications (typically 40–45 ft-lbs) to ensure alignment with the flywheel.


Maintenance and Industrial Use Considerations



  • Routine Inspections:

    • Clean grease and debris from the starter housing to prevent overheating.

    • Check for loose electrical connections or corrosion on 6-volt battery terminals, using a wire brush and dielectric grease.



  • Vibration Resistance: Regularly tighten mounting bolts to counteract loosening from heavy equipment operation.

  • Brush Maintenance: For starters with serviceable brushes, inspect wear and replace if below 1/4-inch length to maintain electrical conductivity.


Troubleshooting Common Issues



  1. No Crank, 6-Volt System:

    • Verify battery charge (6V systems require strict voltage maintenance).

    • Check for broken wires or faulty ignition switch, common in vintage equipment.



  2. Grinding Noise:

    • Worn pinion or flywheel teeth; inspect gears for damage and replace as needed.

    • Misalignment due to loose mounting bolts; retighten to specification.



  3. Solenoid Chatter:

    • Weak battery or corroded connections; clean terminals or replace the battery.

    • Faulty solenoid contacts, requiring replacement of the solenoid or starter assembly.
