🔧 Maintenance

Oil Change:

Every 2,000-3,000 miles or annually, whichever comes first. Refer to manual for precise intervals.

Filter Replacement:

Oil filter should be replaced with each oil change. Specific part numbers for oil filters (e.g., Harley-Davidson 63796-77 or equivalent aftermarket).

Spark Plug Replacement:

Every 6,000-10,000 miles or as needed. Recommended plugs may include Champion, Bosch, or NGK equivalents (refer to manual for exact part numbers).

Chain Adjustment:

Check chain slack every 1,000 miles and adjust as necessary to approximately 0.5-1.0 inch of play.

Ignition Timing Check:

Check and adjust ignition timing every 5,000-10,000 miles or if performance issues arise.

Engine Oil:

Consult manual for specific viscosity grade. Modern recommendations often include SAE 20W-50 motorcycle-specific oil with adequate ZDDP for flat-tappet camshafts. Examples: Valvoline VR1, Brad Penn Penn Grade 1.

Transmission Oil:

Consult manual. Harley-Davidson Formula+ or a quality 80W-90 gear oil with GL-4 rating is often suitable. Avoid GL-5 as it can damage synchronizers if present (though this era might not have them).

Primary Chain Case Oil:

Typically shares oil with the transmission and engine in some configurations. Refer to manual for lubrication path. If separate, refer to manual for specifications.

Brake Fluid:

DOT 3 or DOT 4 brake fluid for hydraulic systems. Check manual for specific type and flush interval.

Shifter Pawl Wear:

The 4-speed transmission's shifter pawl mechanism can wear over time, leading to missed shifts or difficulty engaging gears.

Carburetor Leaks:

Linkert carburetors, while reliable, can develop fuel leaks if not properly maintained or if worn gaskets are not replaced.

Oil Leaks:

Common in vintage motorcycles due to aging seals and gaskets. Regular inspection and gasket replacement are crucial.

Electrical System Aging:

Wiring harnesses can degrade, and components like generators, regulators, and ignition coils may require attention or replacement due to age.

Pushrod Tube Seals:

Pushrod tube seals are a common source of oil leaks on Shovelhead engines.
