·DB· Wing
Lagging has been designed to fit the standard Turn Clean™, XT-reme™
and Heavy Duty wing type pulleys. Tough 65 durometer - SBR (styrene butadiene)
rubber hot vulcanized to a formed heavy gauge metal channel makes
·DB· ready to extend the life of a Turn Clean™ wing pulley
in even the most abrasive applications. ·DB· will not only supply
added life to your pulleys, it will reduce belt wear and can be simply and
economically replaced in the field.
Installation and Replacement Procedures 1. Remove the
Worn Rubber Lagging All tac welds between the replaceable lagging and
the contact bar are broken using a hand chisel or hand grinder.
2.
Clean Remaining Weld from Sides of Contact Bar Using a hand grinder or
chisel, clean all remaining weld from the sides of the existing contact bar.
Remove any rust, dirt, or scale buildup from the sides and top of the contact
bar.
3. Install new Replaceable ·DB· Lagging Insert
Install replacement ·DB· lagging section to contact bar.
Starting at end of contact bar tac weld per welding instructions at slotted
areas.
NOTE: It is
extremely important that the contact bar to lagging section fit-up as tight as
possible to eliminate added stress to the tac welds. A good practice to follow
is to tac weld the replaceable lagging to the contact bar first on the side
towards the direction of rotation, thus ensuring a tight fit in the high
stressed area.
4. Installation when Face Width is Greater than 32.00". Face widths greater than 32.00" will require the addition of a partial
section of the replaceable lagging to be “butted” up against the
32.00" section. Partial Sections less than 6.00" should be discarded. Since the
number and location of the notches in the replacement channel varies, a notch
will need to be cut in the channel, 1.00" in from the end of the partial
section.
