Fig. 17. Adjusting the chain
5. ADJUSTING THE CHAIN
Slacken the rear wheel spindle, i.e. the spindle securing nut on the L.
H. side and the chainwheel sleeve nut on the R. H. side (slightly tap the
spindle as well as the sleeve nut). Then slacken the chain tensioning front
lock nuts and tighten evenly the rear adjuster nuts. Never use force when
tightening these nuts so as to avoid damaging their threads. Having
adjusted the chain tension, retighten the tensioning locknuts properly
then the sleeve nut and finally the spindle securing nut.
Make sure that the wheels are in line. Adjust the rear brake as well,
for having moved the rear wheel the brake might be slightly in constant
operation, and check the stop switch. Check the chain tension every 1600
km, (1000 miles). Remove the chaincase lid and depress the chain. The
free movement should not exceed 2 cm. (3/4 in.) with the machine
laden.
