Chapter 6: Fastening Instructions
Three-Step Fastening
Three-step fastening will be used primarily for joints that have a requirement to synchronize
with another spindle during the incremental stages of the rundown to crush/compre
gasket or grommet or for special joint conditioning (valve cover, oil pan, or body assembly, for
example).
1. Angle control commences at SNUG TORQUE. All angle values are referenced from this point.
2. Once SPEED CHANGE TORQUE is reached or FREERUN REVO
switch from FREERUN SPEED to SLOWDOWN SPEED and continue to fasten to 1ST
TORQUE/ANGLE.
3. The system will fasten to the 1ST TORQUE/ANGLE value during the specified 1ST TIME. 1ST
TORQUE/ANGLE must be reached within the 1ST
4. Upon reaching 1ST TORQUE/ANGLE, 1ST TIME ends and FINAL TIME begins. 1ST
TORQUE/ANGLE is the shift point to TORQUE SPEED
mencing the next step.
(See 4.13
5. The system will fasten to CROSSOVER TORQUE/ANGLE, synchronize with other spindles
and then fasten to STANDARD ANGLE using TORQUE SPEED during FINAL TIME.
STANDARD ANGLE must be reached within the FINAL TIME limits or a reject will occur.
NOTE: When performing multiple step Angle control fastening, the rotation Angle
should be performed as one continuous operation. There should be no intermediate
stop / synchronization points once Snug Torque has been sensed and rotation angle is
being controlled. Under special conditions multiple steps can be performed using i
termediate Torque or Angle stop/synchronization points.
