Turn adjustment bolt on back on gear box
base until proper belt tension is attained.
Square up gear box base parallel to frame by
moving L.H. end (gear box end) to required
position.
Tighten all capscrews.
Make sure gear box base is square on frame
and not set on an angle when adjusting belt tension.
Readjust and tighten idler sprocket on drive
chain.

Check tension by depressing belt at mid span of
jackshaft and clutch pulleys with 3.8-5.2 lbs. of force.
Belt should deflect .23 in. If deflection is incorrect,
proceed to next step. If correct, continue operation.
To adjust belt tension:
Remove (4) capscrews, washers and nuts
securing upper shroud to frame (Fig. 34).
If belt has too much slack, loosen idler pulley
nut, press forward on idler pulley until desired
tension is obtained and retighten idler pulley nut.
If belt is too tight, loosen idler pulley nut, pull
rearward on idler pulley until desired tension is
obtained and retighten idler pulley nut.

Check tension by pressing side of chain at mid
span of upper and lower drive sprockets with 10 lbs. of
force. Chain should deflect .10 in. in each direction
from center (.20 total deflection from side to side). If
deflection is incorrect, proceed to next step. If correct,
continue operation.
