Which is better forged or nodular iron crankshafts?
Forged cranks are generally preferred for performance work, but for most street engines the use of a forged crank is purely a luxury. Nodular iron is a very stable material that provides good service in any street or bracketracing engine. It has the ability to flex under load and withstand considerably more punishment than you might expect.
How does the nitriding of a crankshaft take place?
This process involves the absorption of nitrogen into the steel. Prior to nitriding, the crankshaft is machined, stress relieved, and tempered. Nitriding takes place in a heated container where the crankshaft is exposed to ammonia and nitrogen gas. Nitrides are formed as the gas reacts with the carbon on the surface of the steel.
How does the Hiko nose threadlift system work?
Hiko nose threadlift works by a two-pronged mechanism. Firstly, the threads mechanically prop up the nose tissues wherever they are placed. Secondly, the threads contain little barbs along their length. As the nose threads dissolve, the threads will stimulate natural collagen production by your own tissues.
How are the journals of a crankshaft ground?
The journal and fillet shapes are finalized during the grinding process. Main journals are ground with the crankshaft centerline positioned concentrically. Rod journals are ground with the crankshaft centerline mounted eccentrically, placing the centerline of the rod journals in a centered axis.
How big is the crankshaft nose on a Ford engine?
The crankshaft nose needs to be cut down to the standard 1.375-inch FE diameter, the flywheel mounting surface is shortened by about .060 inch, and the counterweights need to be cut down before balancing is possible.
How do you put a seal on a crankshaft?
Twist the seal and slide it over the crankshaft with the felt side toward the flange. (If the seal does not incorporate a felt, just place the seal on the shaft with its recessed side toward the rear). Bring the ends of the seal back together. Wrap the spring around the crankshaft in the seal areas.

How big of a bolt do I need to install a crank?
Install right crank onto right side of spindle. Thread in bolt to spindle. Self-extracting models align tooth and groove of spindle and crank when installing. Tighten bolt fully to manufacturer’s specifications. The bolt may need 34 Nm to 50 Nm (300 to 450 inch-pounds) depending upon brand.
