Frequently Asked Questions

What are the main Harley-Davidson engine models discussed in the video?

The video covers the evolution of Harley-Davidson engines, detailing the Knucklehead (1936-1947), Panhead (1948-1965), Shovelhead (generator 1966-1969 and alternator 1970-on), and the Evolution (1984-on) models.

How are transmission issues like not engaging third gear typically resolved?

Transmission problems such as failure to engage third gear are often caused by a bent shifter fork, which is made of mild steel. Inspection and straightening or replacement of the fork are common repair methods.

What specialized repair is shown for transmission race issues?

When the steel race in a transmission case moves, a specialized repair involves cutting out the old race and installing a new insert, as welding steel directly to aluminum is not a viable solution.

What are the recommended packing procedures for shipping Harley-Davidson engine components for rebuild?

Cylinders and heads should be packed separately in cardboard boxes within a larger box. The lower end should be placed in a plastic milk crate with cardboard and rags to secure the flywheel during shipping.

What quality components are used in the engine rebuilds?

Rebuilt Harley engines feature new hand bearings, pin bearings, Timken bearings, and 54-tur roller bearings. They also use high-quality three-hole crank pins from manufacturers like Gyms Machining or Eastern Motorcycle Parts.
