Figure 41—Rear Drive Chain and Connecting Link
(3) Pull on lower half of chain, guiding upper part while it rotates around countershaft sprocket, until removed. If a new rear chain is to be installed, one end can be linked to the upper half end of old chain and can be pulled onto countershaft sprocket as old chain is removed.
b. Install. When installing a new rear chain and/or countershaft sprocket, it may be necessary to set rear wheel ahead in order to get chain on (par. [60]).
(1) Start end of chain over countershaft sprocket teeth, using starter crank to turn sprocket. After chain end has reached front half of sprocket, it will be necessary to guide end under sprocket and out of sprocket cover. Center chain so that ends engage rear sprocket teeth, back of the axle.
(2) Install connecting link, side plate and spring clip. See that open end of spring clip is to the rear with regard to chain travel (like the end of an arrow). If original spring clip is bent or damaged, use a new one.
(3) Adjust rear chain (par. [60]).
(4) Check rear brake adjustment (par. [96]).
