New Fits Yamaha Banshee 350 Replacement Crank Shaft Crankshaft Welded Trued 1987-2013

The internal combustion engine's crankshaft is the engine's backbone. The crankshaft is in charge of keeping the engine running smoothly and turning linear motion into rotational motion. To provide a longer service life, crankshafts should have extremely high fatigue strength and wear resistance. The crankshaft is subjected to a lot of cyclical loading. When choosing materials for crankshafts and camshafts, a high coefficient of thermal expansion can be an issue. Materials such as ductile iron, forged steel, and titanium are frequently used to make shafts. * RAPTOR 660 * RAPTOR 700 * BANSHEE * BLASTER 200 * YFZ450 Product Photos Product description This is a crankshaft for a Fits Yamaha Banshee, any year, 1987-2006.

• The piston goes up and down in a Compatible with Linear reciprocating Compatible with Action as the crank revolves. Rotational motion is converted to Compatible with Linear motion using a crank and piston arrangement. Depending on the orientation of the guide, the Compatible with Linear motion can be vertical or horizontal (or in another direction).
• Compatible with Cast Iron or cast steel crankshafts are used in the majority of OEM crankshafts. The fundamental shape of the crank is created by pouring molten metal into a sand casting, which is then machined to precise tolerances.
• THE CAUSE OF BROKEN CRANKSHAFTS IS RARELY MATERIAL FATIGUE BROUGHT ABOUT BY EXTENDED USE. Mechanical overload of the crankshaft due to aberrant combustion, water hammers, and other factors are far more common causes of damaged crankshafts. Engine jams owing to a damaged gearbox, loose counterweights, etc.
• Signs of a bad crankshaft: - A forging or casting flaw - Insufficient lubrication - Bearing wear - Loose bearing main caps - Distorted bearing bores - Improper bearing clearance - Bearing failure
