Replacing the Belts
For Puller Model 3-20 (continued)
4 Remove the belt from the puller. Check the rollers and pulleys for buildup,
especially inside grooves. Clean if necessary.
5 Reverse the process to install the new belt.
Make sure ribs inside the belt fit
properly into grooves. Keep tension
on front and back sides of the belt
as even as possible while tightening
the belt tension. Turn each rod 5 to
10 revolutions, then switch to the
other side.
6 Adjust belt tension and belt gap. See Installation Section, entitled Adjusting
the Belt Tension and Setting the Belt Gap.
7 Reinstall the upper and lower belt guards.
