High Quality Industrial Factory Stainless Steel in Brasilia
Stainless steels generally contain between 10-20%chromium as the main alloying element and are valued for high corrosionresistance. With over 11% chromium, steel is about 200 times moreresistant to corrosion than mild steel. These steels can be divided into three groups based on their crystalline structure: Austenitic: Austenitic steels are non-magnetic and non heat-treatable, andgenerally contain 18% chromium, 8% nickel and less than 0.8% carbon. Austenitic steels form the largest po...

Stainless steels generally contain between 10-20%
chromium as the main alloying element and are valued for high corrosion
resistance. With over 11% chromium, steel is about 200 times more
resistant to corrosion than mild steel. These steels can be divided into
three groups based on their crystalline structure:
Austenitic steels are non-magnetic and non heat-treatable, and
generally contain 18% chromium, 8% nickel and less than 0.8% carbon. Austenitic steels
form the largest portion of the global stainless steel market and are
often used in food processing equipment, kitchen utensils and piping.
Ferritic: Ferritic steels contain trace amounts of nickel, 12-17% chromium, less than 0.1% carbon, along with other alloying elements, such as molybdenum, aluminum or titanium. These magnetic steels cannot be hardened with heat treatment, but can be strengthened by cold working.
Martensitic steels contain 11-17% chromium, less than 0.4% nickel and
up to 1.2% carbon. These magnetic and heat-treatable steels are used in
knives, cutting tools, as well as dental and surgical equipment.
Today we are going hands on with a front Driveshaft made by Niche Industries. This will fit all Grizzly 660′s from 2003-2008. If your old shaft has failed, then like thousands of other riders you’re here because you are looking for a solid replacement.
This shaft sits in between the engine and front differential, Its connected with 2 couplers and is used to transfer power from the engine to the front differential.
When Yamaha originally designed the shaft-and-coupler system on the Grizzly 660 they didn’t account for the volume of dirt and grit that can make its way in-between the coupler and shaft. Typically this happens when you’re mudding, but it can also happen from riding in sand or loose dirt. The breakdown begins when the small pieces of sand make there way in between the splines of the coupler and shaft, after time they begin to break down the splines and eventually the coupler and shaft start slipping which leads to loss of power to the front differential.
Niche wasn’t able to stop grit and sand from doing its thing but they did make some improvements over the stock shaft. The original shaft was made of forged steel and Yamaha used induction heat-treatment on the surface in order to harden the steel (for those of you wondering what induction is, its just a fancy term for using electromagentic current to harden a surface) the problem is induction only provides effective hardness to the very surface of the metal, however once the sand has breached the surface it can essesntially cut through the rest of the metal like butter.
Niche made improvements, starting with a forged 4340 chromemoly bar, the same material used to make Niche High-Strength Axles. Unlike the original Yamaha, the shaft and joint are chemically hardened before receiving induction heat treatment, this additional Chemical hardening process means that it will last longer when exposed to the same conditions as the original.
If you are due to replace your shaft, you may also want to consider replacing both couplers at the same time, since your current ones are likely pretty warn out. Niche couplers use the same materials and undergo the same hardening process as its drive shafts. For optimal performance, pair your new driveshaft with a set of new couplers.
Partdiscounter sells more 660 parts than just about every other online retailer for a reason, we provide a quality products at an affordable prices and we deliver to you fast.
As with all Partdiscounter products, these shafts are in stock and ready to ship right away. We are happy to offer 2nd day delivery on nearly everything we sell. If you need it faster, we’ve also got you covered with next day rates starting at less than $5.00.
