Pull Studs

Two quick questions:

What torque do you use to install pull studs on CAT40 tooling? Do you install dry or possibly mild lock tight?

Are CT40 and CAT40 holders the same?

Thanks

Yes CT40 and CAT40 are the same. Here is a link and copy of pull stud torque and lok-tite guidelines. If you want to go that route. I just assemble dry and never had an issue.

We do not recommend any anti seize or lubricant during assembly, light oil is fine. Medium strength lock tight may be used only if carefully applied after first thread in tool holder and do not apply lock tight to the retention knob. This is to ensure lock tight is located towards the strongest area of the tool holder and will not be able to bulge tool holder taper if it should happen to expand. Use sparingly.

Here are the following pull stud / retention knob torque specs

BT30 pull stud / retention knob torque specs 25-35 ft lbs

CAT40 or BT40 pull stud / retention knob torque specs 45-55 ft lbs

CAT50 or BT50 pull stud / retention knob torque specs 75-90 ft lbs

Pull stud / retention knob torque should be checked as part of your scheduled maintenance program.
