How to Tighten the Chain

1. Measure the Slack in Your Chain. Check the factory recommended slack in your user manual (usually 1-1.5 inches) Have somebody sit on the ATV to simulate the tension the chain normally sees.
2. Tighten Your ATV Chain. Loosen, but don’t remove the bolts on the bearing carrier at the rear of your machine.

Why does my four wheeler chain keep falling off?

Re: chain keeps coming off Check for a play in your swing arm pivot bearings (where the swing arm bolts to the frame). If the bearings are worn out and it makes a big play and that the chain is loose, your chain will come off. You can also put a banshee chain slider on your swing arm to help prevent this.

How tight should a ATV chain be?

Stack three fingers on top of one another and place them behind the chain slider. With the chain draped across the top of your index finger, it should be taut overall. Anything looser or tighter calls for adjustment.

What is a 420 chain?

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).

What’s the difference between 420 and 428 chain?

The primary difference between 420 and 428 is the pitch of the links. A 130 link 428 chain will be longer (and generally speaking, heavier-duty) than a 130 link 420 chain.

How do I know if my chain is 420?

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.

Will a 420 sprocket fit a 40 chain?

They are the same pitch (1/2″) but 420 is narrower used primarily on the thin, lightweight kart sprockets. 40 chain will run on a 420 sprocket but I think it will have way too much side to side play.

Will a 420 chain fit a 40 sprocket?

#420 will fit on #41 sprockets, its just a little bit heavier duty with a larger pin. the 40 chain will fit on a 41 sprocket and the 41 chain will fit on a 40 sprocket but only if you shave the edges down a bit because a 40 sprocket is wider.

What does a 40 chain mean?

The chain in use on modern bicycles has a 1⁄2 inch (12.7 mm) pitch, which is the distance from one pin center to another, ANSI standard #40, where the 4 in “#40” indicates the pitch of the chain in eighths of an inch; and is standard 606 (metric) #8, where the 8 indicates the pitch in sixteenths of an inch.

Will a 40 chain fit a 35 sprocket?

No. A #40 chain is 1/2″ between the pins and 5/16″ inside width. A #35 is 3/8″ between the pins and 3/16″ inside width. There is no way it will work.
