CARRIER-PLANET 3K2049 - Caterpillar

When the tap is used to make threads in a hole that goes all the way through the component, make sure the end of the tap does not go all the way through the component. If the first full thread goes all the way through the hole, there will not be any taper to hold the Taperlock stud in the correct position.
Taperlock studs must be tightened to a specific torque. The torque specifications for most Taperlock studs used by Caterpillar are shown in the chart.
During installation, 9S3263 Thread Locking Compound can be used to help prevent loss of torque on the stud. The 9S3263 Thread Locking Compound is also to be used to seal Taperlock studs in which the hole is open to a compartment which contains fluids.
