High Speed Gear

Installation instructions for high speed gear:

gear plastic cover removedRemove Plastic Cover, bar & chain

gear clip offRemove “C” clip (be careful not to lose it)

gear newRemove old gear & replace with new High Speed Gear

gear new with washerPlace Fender Washer on gear & replace “C” clip (again be careful not to lose it)

Be sure to align “C” clip to the recesses in the shaft.

Mark off a 1/4″ on your bar (shown here in red)

Grind off that 1/4″

(use either a bench grinder or a “hummer” wheel on a die grinder)

Hummer wheel (1/4″ shaft) available at hardware stores

gear plastic cover modIf you have an E140, cut away some of the orange plastic on the inside of the cover that goes over the gear. (otherwise the chain will rub)

An E-14 will not need modifying

Replace the plastic cover

You will probably need to add 1 tooth to your 3/8″ chain.

We carry a chain for a 14″ bar that has an extra tooth.

Run chain a little tighter than usual to prevent it from coming off the sprocket at high speed.
