Roller Chain Information


A chain consists of steel pins that are rubbing inside of "steel tubes". These are commonly called rollers, but it is obvious they do not roll. They just rub back and forth at very high speeds, under considerable load, pressure and heat.

Squirting oil or even chain lube directly on these rollers does very little good unless the lubricant is given time to penetrate between each pin and the corresponding tube. The lube must go along the side links on each side of the chain, then allow 8 to 10 minutes for penetration and evaporation before starting the engine to ensure the centrifugal force will not sling it all away.

The clutch sprocket and the main drive sprocket should be perfectly aligned so they don't rub against the side links. Rubbing wears the teeth down rapidly and ABSORBS HORSEPOWER.

All chains stretch over time so when the chain starts coming off because it's too loose, move the engine forward or backward to take up the slack in the stretched chain. There does come a time when the chain is just too used up and needs to be replaced.

Chain Adjustment for Centrifugal Clutch Karts


Chain

First, remove any guards covering the drive components.

Then loosen - but do not remove, the four engine mounting bolts (1). Use an open end wrench and a socket wrench, most likely a 9/16. Slide the engine until you take up the slop in the chain.

Slide the engine as nessessary to obtain a 1/4" to 3/8" of chain flex.

Be sure the clutch sprocket (2) and the drive wheel sprocket (3) are perfectly aligned.

Securely tighten the four engine bolts. Re-check the chain tension.

Replace the guards covering the drive components. Install new guards, if damaged.

Do NOT over tighten the chain, it will wear down the sprocket teeth in record time!

For best chain life, lubricate with a graphite type lubricant such as a spray-on type that evaporates leaving graphite on the chain.

Using motor oil will do but may cause dirt particles to stick to the chain resulting in abrasion. Motor oil is widely used but graphite type lubrication is superior.

Chain Replacement

Removal

Remove the guards covering the drive components.

Rotate the drive wheel to place the master link (3) in an accessible position between the two sprockets.

Slide the retaining clip (1) of the master link (3) until the reliefs are centered over the link pins. Remove the clip and side plate (2).

Slide the master link out and remove the chain.

Installation

Install new chain.

Slide the pin portion of the master link (3) in to each end of the chain to be connected.

Slide the side plate (2) portion of the master link on to the pins.

Slide the retaining clip (1) on to the pins until the clip snaps securely in to place.

Caution

The master link should be installed with the open end of the retaining clip (1) facing away from the direction of rotation (4).
