Hub/Blade Installation
1. Align the center slot of 260-3060 Blade Lock Plate with the 5/8” bolt holding the hub on. be sure that the
6 holes on the hub are fully visible. If they are not visible, tighten the 5/8” center bolt until they are.
2.
With the hub properly seated on the overhung load adapter’s tapered shaft and the carbide teeth attached
to the saw blade (
260-0550
), check the center hole of the saw blade for fitment on the hub (reference
Illustration 6-2
). The fit between the two needs to be tight but not “force on” tight. Die grinding the
center hole of the blade will be required if binding occurs; if possible, only use flapper wheel to do this
grinding. Confirm the fit between blade and hub, then set blade on hub. Install the blade onto the hub, line
all 6 holes up with the hub and blade, install and tighten
ONE
1/2”x 1.5” grade 8 bolt.
3. Line up a slot on the
260-3060 Blade Lock Plate
over the 1/2” bolt head and 5/8” bolt head. the blade
lock plate should sit flat against the blade bar. if the lock plate does not sit flat, tighten the 1/2” bolt until
both slots line up and the lock plate sits flat against the bar.
4. Install the second 1/2”x 1.5” grade 8 bolt in the opposite
round
hole to hold the blade lock plate in place.
5. Align
260-0650
(Wear Plate, Bottom, 4 bolt) so that all 4 holes are aligned and the wear plate sits flat
against the
260-3060 Blade Lock Plate
.
6. Install four 1/2”x 2” grade 8 bolts with blue Loctite and torque to
80 ft/lbs.
