and drive belt width adjustment crank.

Important – Before removing chain, mark
both front and rear sprockets/chain with
chalk or paint to be sure sprockets/chain
when re-assembled, will be in same position
as before disassembly. Figure 5-6A and B.
Do not rotate sprockets once chain is
removed. (This would result in the right and
left drive assemblies not being parallel.)
