4.
Check the alignment of the Sheaves by placing a Straightedge flat against
the front face of the PTO Sheave
(Figure 32).
5.
Check the gap from the Straightedge to the Belt near the Flywheel Sheave
and near the PTO Sheave. If the gap is the same then no adjustment is
needed. If the gap is not the same then adjustment is necessary, correct the
alignment as follows:
a)
Use a 1/8" Allen Wrench to loosen the Bushing Set Screw
(Figure
33).
b)
Use a 7/16" Wrench to remove the three Sheave Bushing Bolts.
NOTE:
Place a block of wood into the PTO Sheave Spokes to help hold the belt to
loosening the Sheave Bolts.
c)
Reinstall the three Bolts in the Threaded Holes adjacent to the
Holes that the Bolts where removed from.
d)
Slowly tighten the Bolts evenly and alternately (1/4 to 1/2 turn)
until the Bushing releases from the Flywheel Shaft.
e)
When the Sheave is loose, remove the three Bolts and reinsert
them into the original Retaining Bolt holes.
f)
Move the Sheave Bushing in or out on the Flywheel Shaft as
needed to take up the difference that you measured for the gaps
between the Straightedge and Belt.
NOTE:
Prior to retightening the Bushing Retaining Bolts, The un-tightened Sheave
will need to be approximately 1/8" past the original straightedge to allow
for compression of the Bushing during the tightening process.
g)
Slowly tighten the Bushing Retaining Bolts evenly and alternately
(1/4 to 1/2 turn).
h)
Recheck the alignment after tightening the Bolts, and then
retighten the Bushing Set Screw.
NOTE:
Make sure that the Belt or Sheave is not hitting the Frame.
NOTE:
The belt on your DR 3-POINT HITCH CHIPPER is tensioned with a spring-
loaded idler arm and pulley that is set at the factory. As the Belt stretches
from use, the Belt tension may need to be adjusted.
6.
Reinstall the Belt Guard.
