Crankshaft Kit: Reinforced Crankshaft, Woodruff Key, Crankcase Gasket, R.Crankcase Gasket, Die-Hard Alpha Cam Chain
Description
■Details
This reinforced crankshaft is ideal for the SP Takegawa 88cc / SCUT 106cc big bore engines that use a stock crankshaft.
41.4mm stock stroke specification.
X-shaped connecting rods
Forging material is machined, and an X-shaped cross section is adopted.It is lightweight and strong enough, and its buckling stress diffusion and torsional rigidity are greatly improved.
Surface shot finish.
Strengthening the Journal Department
A special bearing with a larger inner diameter is used for the crankshaft journal bearing.As a result, the shaft diameter of the journal section, where the stress on the crankshaft is concentrated, can be increased from 20mm to 22mm to increase the strength of the shaft.
Increased crank pin size
The crank pin of the large end part is enlarged from stock Φ23.1 to Φ25.1 to increase the strength of the large end part.
Die Hard Alpha Cam Chain
Solid bushings are used: This is a high-precision solid bushing chain with excellent wear resistance, employing a highly rigid solid bushing with a seamless and smooth surface and excellent roundness.The wear life is 1.8 to 4 times longer than that of the standard product, a revolutionary improvement in performance.
