TO REMOVE FANSHAFT DRIVING CHAIN
To remove the fanshaft driving chain the camshaft chain must first be
removed. (See page 57.)

chain and remove the seat pin and rocker pin.
Remove the fanshaft driving chain.
TO REPLACE FANSHAFT DRIVING CHAIN
Place the chain on the fanshaft and camshaft driving sprockets with the
arrows, which are stamped on the outside links, pointing in the direction in
which the chain is to run. If the chain is so placed on the sprockets that it
runs in the opposite direction, it will very quickly destroy itself.
Bring the ends of the chain together, preferably on the larger sprocket.
Insert pins and rivet. (See under "Directions for Riveting Engine Chains,"
page 59.)
It is unnecessary when installing a fanshaft driving chain to pay any attention
to the relative positions of the sprockets upon which the chain operates,
but the ignition must be re-timed after both chains have been replaced. (See
under "To Time Ignition," page 67.) * w.-iofl^/ «**#^3
