then replace when all surfaces are worn.

screw each month.

left; (b) Slip the old belt from the pulleys and install
the new one; (c) Slide the drive motor to the right
to tighten the belt so there is very little deection of
the belt; (d) When correct belt tension is acheived,
tighten the screws.
