Power Drawbar Maintenance - 770M/1100M

Maintenance

Examine Air Pressure

Appropriate air supply helps with smooth actuation, and prevents premature component failure.

• Examine the air to the Power Drawbar to make sure that it's:

  • Between 90 psi and 120 psi (620 kPa to 825 kPa)

  • Been lubricated with common air tool oil

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:

  • Contact surfaces between spring washers

  • Eccentric pivot mount

  • Top of the drawbar (below the drawbar flange and the spring washers)

Examine Wear Items

• Regularly examine the following wear items:

  • Spring Washers Inspect all spring washers once a month for cracks. If they're damaged, immediately replace them with Power Drawbar Spring Washer (PN 31319) .

  • 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:

    • Drawbar, R8, PCNC 1100, Power Drawbar (PN 31320)

    • Power Drawbar Alignment Bushing (PN 31330)

    • Tormach Tooling System (TTS) Adapter Collet: R8 (PN 50568)

    • Power Drawbar Cylinder Rebuild Kit (PN 32093)
