Take my advice: Don\u2019t save money by attaching industrial ANSI 50-gauge chains to your 520 or 530 motorcycle dental tray!<\/h2>\n\n\n\n

While both the 50-gauge and 520 chains have a 5\/8-inch pitch and a 1\/4-inch inner width, making them look identical in size, they harbor a killer pit: the 50-gauge chain\u2019s rollers (10.16mm) are smaller than the standard motorcycle 520 rollers (10.29mm). That small difference can quickly chew your expensive tooth tray into \u201cserrations\u201d. Also, for those of you struggling with whether to use 530 or 630 chains when renovating your old car, let me be frank: the 630 is long outdated. Replacing your vintage 70s high-displacement locomotive from a 630 to a modern 530 chain will not only lose nearly two pounds of rotating mass, but will also significantly increase its tensile strength.<\/p>\n\n\n\n

Mixing industrial hardware into a high-speed motorcycle transmission system is not an option without accurate caliper data. Let\u2019s break and tear below, how these mismatched size chains can ruin your car step by step.<\/p>\n\n\n\n

RPS Iron Law Of Compatibility<\/h2>\n\n\n\n

Many technicians who know a little bit of fur look at the standard pitch table and find that the numbers match, so they think the chains can be exchanged freely. But the real experts look at \u201cRPS Triangle \u201d\u2014\u2014roller (Roller), pitch (Pitch), side clearance (Side-clearance), one of the three is indispensable. The pitch only tells the distance between the two pins; the roller diameter determines whether the chain can fit perfectly on the bottom of the disc teeth; and the side clearance determines whether the chain plate will scrape against the engine box at high speeds. If just one of these three points doesn\u2019t match, your drivetrain will eventually fail.<\/p>\n\n\n\n

520 Vs. 50 Chain: 0.13mm Deadly Trap<\/h2>\n\n\n\n

If you hard-fit a No. 50 agricultural machinery chain onto a 520 motorcycle disc, the disc will absolutely wear out quickly and irreversibly. Both chains have a 5\/8-inch (15.875 mm) pitch and a 1\/4-inch (6.35 mm) inside width. What is the fatal difference? Roller diameter! The ANSI No. 50 chain has 0.400-inch (10.16 mm) rollers, while the 520 motorcycle chain has 0.405-inch (10.29 mm) rollers.<\/p>\n\n\n\n

Don\u2019t underestimate this measly 0.13mm, it\u2019s enough to ruin the entire set of transmissions. The 10.16mm rollers on a 50-gauge chain are too small and will sink too deep into the teeth of a 520-tooth disc, with the force-bearing surfaces completely wrong. Normally, the force of acceleration should be evenly distributed across the arc of the tooth, but now because the rollers are small, the huge pulling force is concentrated at a tiny point of force. This local stress will pull and deform the teeth of the tooth disk into barb shape within a few hundred kilometers. In order to save the 20 or 30 yuan to buy a tractor chain, I ended up paying thousands of yuan to replace the front and rear discs, which was definitely not worth the loss.<\/p>\n\n\n\n

530 Vs. 50-Gauge Chain: The Size Doesn\u2019t Match At All<\/h2>\n\n\n\n

You want to attach a regular 50 industrial chain to a 530\u2019s dental tray? Physically impossible. Some newbie pictures are cheap and want to do this, but the inner width is not allowed at all. The width between the inner and outer plates of a 530 chain is 3\/8 inch (9.53 mm), while the inner width of a 50-gauge chain is only 1\/4 inch (6.35 mm).<\/p>\n\n\n\n

If you force the No. 50 chain onto the 530 disc, the chain plate will hit both sides of the disc teeth directly, and the rollers will not touch the tooth roots at all. You can\u2019t even drive a kilometer in this state. While industrial chains do have widened versions \u2014\u2014like the 50-2 (double-row chain) or some agricultural specialty wide chains, to accurately match the 3\/8-inch inner width and 10.29mm rollers of the 530 teething pan, you still have to be honest and buy a dedicated motorcycle chain.<\/p>\n\n\n\n

530 And 630 Chains: The Only Way To Renovate An Old Car<\/h2>\n\n\n\n

Classic large-displacement motorcycles from the 1970s and 1980s (such as the Kawasaki KZ1000 or Suzuki GS1000) came with big, bulky 630 chains. The reason was simple: metallurgical technology at the time was not good, and if we wanted to withstand 90 horsepower, we had to rely on stacking and thickening. The 630 chain reached an exaggerated pitch of 3\/4 inch (19.05 mm), while the current 530 chain has a pitch of 5\/8 inch (15.875 mm).<\/p>\n\n\n\n

Downgrading (or rather upgrading) the 630 drive to a 530 configuration is a must for modern vintage car refurbishment players. Today\u2019s tensile steel and X-seal technology can easily withstand a modern 530 chain with a tensile force of more than 10,000 pounds, which is the strength that has long pressed the original 630 to the ground and rubbed it.<\/p>\n\n\n\n

Throw away the 630 and lose 1.5 to 2 pounds of rotating mass directly from the drivetrain. This substantial \u201clightening\u201d can immediately improve the acceleration response of the rear wheels, reduce the gyroscopic effect and make bending and dumping faster, while also greatly reducing the wear of the transmission output bearings. Moreover, if you want to buy a 630 chain now, you can only choose those expensive and unpopular brands; after switching to 530, there are hundreds of cost-effective and high-performance chains on the market to choose from.<\/p>\n\n\n\n
