#35 chain is the most common type of chain used on mopeds, mini bikes, and full size go karts. #35 chain has a 3/8″ center to center spacing between each link pin, a 3/16″ spacing between inner plates, and is approximately 3/8″ wide.
What size is a mini bike chain?
What Size Chain Should I Buy ? Most go kart chains and mini bike chains have the chain size stamped directly on the chain links. #35, 40, 41, 420 and 50 chain are used on American Go Karts and Mini Bikes. An 11 or 12 tooth clutch sprocket usually indicates the use of 35 chain.
How do I know what mini bike chain I have?
Go-kart chain numbers take the first letter from the pitch. And the last 1 or 2 digits from the roller width. For example a 420 chain has a pitch of 4/8-inches and a 520 chain has a pitch of 5/8-inches. To start measuring your chain size you need to start at the sprocket.
What kind of chain is on the Coleman mini bike?
The 42-link 420 chain for the Coleman CT200U Trail and CT200U-EX mini bikes is the shorter of these bikes’ two chains. Note: This is sometimes called a 21-link chain in some literature. Our current chain count includes both outer AND inner link plates!
What does a 420 chain mean?
This is the distance between the pins. The second and third digits combine for roller width, with a decimal point inserted between the second and third digits. For example, a 420 chain has a pitch of 4/8″ = 1/2″ (12.70mm) and a roller width of 2.0/8″ = 1/4″ (6.35mm).
How do I know what type of chain I have?
How to Tell What Size Chain You Have
The distance from the center of one pin to the center of the next pin, also known as the “pitch” of the roller chain.The diameter and width of the roller.Plate thickness, determined by measuring the plates from one flat side to another.
Is 40 chain the same as 420?
Difference between 420 chain and 40 chain
Both 420 and 40 chains have the same tensile strength and pitch, the only major difference is the width between the inner plates of #40 is larger than #420 by 1/16″.
What is a #25 chain?
#25 roller chain is a 1/4″ pitch ANSI Standard roller chain designed for light-duty or space confined applications. It’s the smallest size roller chain on the ANSI spectrum of roller chains but offers ample performance, strength, and durability for its small form factor.
How long should a mini bike chain be?
Here’s our rule of thumb for chain length: 3′ of chain for a Go-Kart. 5′ of chain for a Mini-Bike. 10′ for anything stretched.
What chain size do I have?
To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.
How do I know what size chain I need?
To determine the pitch (chain size), you’ll need to measure the distance between any three consecutive rivets, then divide the result by 2. The rivets are the small, round pegs/studs that hold the chain segments together. Measure from the first to the third, then divide that number in half to get your chain pitch.
How do I find my chain number?
Chain Dimensions
Chain types are identified by number; ie. a number 40 chain. The rightmost digit is 0 for chain of the standard dimensions; 1 for lightweight chain; and 5 for rollerless bushing chain. The digits to the left indicate the pitch of the chain in eighths of an inch.
What size chain does a Coleman mini bike use?
Front Jackshaft Size #420 Chain for Coleman CT200U CT200U-EX BT200X Mini Bike, 2 Pack.
What size chain is on a Coleman 100cc mini bike?
This is a 140 link #35 size chain with a number of recreational applications. Using 70 outer links and 70 inner links (140 total), this chain can be a perfect replacement for a broken or missing one on a Coleman CT100U Trail mini bikie.
What is a #40 chain?
#40 roller chain is a 1/2″ pitch ANSI B29. 1 industrial duty roller chain that is manufactured with precision components and high-strength carbon steel alloys. Being made to ANSI dimensional standards means that this chain directly interlaces with other brands and interlaces.
What does 520 mean on a chain?
(3) The size of a chain is designated by a three-digit number (520, for example). The distance from the center of one pin to the center of the next is called pitch. Pitch is represented by the first digit, which is 4, 5 or 6.
Which is bigger 420 or 428 chain?
WHOAAA, 420 and 428 chains are the same pitch (the 4 means 4/8″ which is of course 1/2″). They will be the same length, the width is greater on the 428.
