Chain Maintenance
Figure 16 Figure 17
The XTR uses a number 25 drive chain to supply power to the rear wheel. (Fig. 16)
Extreme caution should be used when servicing the drive chain. Service or maintenance to the chain should
ONLY be performed when power to the electric motor has been disconnected from the battery.
The chain should be lubricated at regular intervals. Applying a commercially available chain lube, such as WHITE
LIGHTNING, after every re-charge of the batteries is ideal. Follow the directions provided by the chain lube
manufacturer. (Fig. 17)
Figure 18
To adjust the chain tension, begin by checking the slack in the
upper drive chain run midway between the sprockets (see
figure 18). Drive chain slack should be adjusted to allow ½” of
vertical movement by hand. If the chain is slack in only certain
areas, then some links are kinked and binding. This can
frequently be eliminated with lubrication.
Wear on sprockets is illustrated in Fig.19. If sprocket teeth
show signs of hooking, or wearing on the teeth, they should
be replaced.
A worn sprocket will quickly damage a new chain and vice-
versa. Chains and sprockets should be replaced as a set.
