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.
