Chapter 7 - Adjustments
GEARBOX DRIVE CHAINS (Fig. 19)
Adjust the gearbox drive chains to deflect 1/4″ to 3/8″
(6.4 mm to 9.5 mm) with 5 lbs. (22 N) force at the
mid-span of the chain. Adjust the chains by moving the
idler blocks. DO NOT OVERTIGHTEN THE
CHAINS.
Before tightening the worm gearbox drive chain, do the
following:
