4.1 MAINTAINING THE POWER DRAWBAR
Read the following sections to understand how to maintain the
Power Drawbar:
l "Examine Air Pressure" (below)
l "Lubricate the Power Drawbar" (below)
l "Examine Wear Items" (below)
4.1.1 Examine Air Pressure
Appropriate air supply helps with smooth actuation, and prevents
premature component failure. Examine the air to the Power
Drawbar for the following:
l Make sure that it's between 90 psi and 120 psi.
l Make sure that it's been lubricated with common air tool oil.
4.1.2 Lubricate the Power Drawbar
Every 5000 cycles (or six months — whichever comes first),
use Anti-Seize to lubricate the following parts on the Power
Drawbar:
o
Contact surfaces between spring washers
o
Eccentric pivot mount
o
Top of the drawbar (below the drawbar flange and the
spring washers)
4.1.3 Examine Wear Items
Examine the following wear items regularly:
o
Spring Washers. Inspect all spring washers once a month
for cracks. If they're damaged, replace them immediately
with the following item:
o
Power Drawbar Spring Washer (PN 31319)
o
Tormach Tooling System® (TTS®) Collet and Drawbar.
Using the Power Drawbar may cause these items to wear
faster than with a manual drawbar. Inspect them
regularly, and immediately replace any damaged items
with the following:
o
R8 Drawbar (PN 38793)
o
Power Drawbar Alignment Bushing (PN 31330)
o
Tormach Tooling System® (TTS®) Adapter Collet: R8
(PN 35356)
o
Power Drawbar Cylinder Rebuild Kit (PN 32093)
