🔧 Maintenance

Oil Change Interval:

Typically every 1,000-1,500 miles or annually. Refer to manual for specific recommendations.

Tune Up Interval:

Regular checks of ignition timing, carburetor adjustment, and chain tension recommended every 3,000-5,000 miles or annually.

Engine Oil Type:

Viscosity varies based on ambient temperature. Typically SAE 50 or 20W-50. Harley-Davidson recommends specific formulations.

Engine Oil Capacity:

Approx. 3 quarts (2.8 liters) for dry fill, varies with oil filter change.

Transmission Oil Type:

Harley-Davidson recommended primary lubricant or equivalent.

Transmission Oil Capacity:

Approx. 1 pint (0.47 liters).

Ironhead Tendencies:

Oil leaks are common due to aging seals and gaskets. Ignition system can be finicky. Carburetor adjustments are frequent requirements. Kick-start can be challenging for some riders.

Carburetor Idiosyncrasies:

Linkert and Marvel Schebler carburetors require precise adjustment and can be sensitive to atmospheric changes.

Brake Performance:

Drum brakes of this era offer less stopping power compared to modern disc brakes and require regular adjustment and inspection.
