How can you identify a Callies crankshaft?
Please provide our technical department with the 5 or 6 digit serial number and they can help you identify your crankshaft. Since 2000, Callies has an electronic record of all Callies crankshafts produced. *Callies is not responsible if the dimensions of the questioned crankshaft have been changed since its production date, i.e. pin and main journal sizes.
What is a Callies “Stealth” Crankshaft?
We often hear the word Stealth used to identify a Callies crankshaft. This is understandable, since the very first days of Callies Performance Products the word Stealth has been present in both our big and small block Chevy forgings. In the early years of Callies, the word Stealth gave our product a trade name. It was also strategically placed to allow Tech. Inspectors an easy way to identify the crankshaft’s source and if it were billet in origin.
Callies Performance Products began manufacturing crankshafts for the performance market over 25 years ago. By today’s standards CNC machining in the mid 1980’s was very fundamental. Significant advancements in CNC programming software, computer memory and processing speeds have given us capabilities that had been unthinkable during those early years. These continually advancing capabilities and the never ending quest for product improvement have brought us today to the point of a fully machined crankshaft. For the most part there are no (As Forged) surfaces left on our current crankshafts.
To this day, our forgings have the word Stealth formed into the #1 pin arm just as they have for the past 25 years. The Callies Stealth crank lives on, but in today’s highly refined condition the original trade name is no longer visible.
Your crankshaft regardless of age can easily be identified by the Serial Number stamped into the face of the number one counterweight. Callies maintains a complete process history for every crankshaft produced over the last fourteen years. We can easily validate the authenticity of any crankshaft produced in our facility. Call us anytime to verify that your component is a genuine Callies Crankshaft.
What is the proper procedure for installing stud kits?
1. Make sure threads in crankshaft are clean and are good threads.
2. Lightly coat the end of the stud going into the crank with “NEVER-SEEZ” (note: “Never-Seez” is the only material to be used!)
3. Install stud with 15 ft./lbs. of torque. DO NOT use any Loctite type products.
4. Install damper and accessories.
5. Install .300″ thick washer. Make sure the surface the washer is going against is parallel.
6. Lightly coat threaded area where the nut goes and coat the bearing surface of the nut with “NEVER-SEEZ.”
7. Install nut using 75 ft./lbs. of torque. (except CPPI-013F use 65 ft./lbs. of torque)
