Hot Alignment Check for Open-Drive Machines
Alignment of compressor with heat exchangers, gear, and driver may be affected by the
operating temperatures of the various components. When all machine components have
reached operating temperature (after running near full load for 4 to 8 hours), make a hot
alignment check.
With the proper equipment and procedure, hot check can be made with either assembled or
disassembled couplings. The procedures are detailed in the Maintenance section.
A clamping tool, Part No. TS-170, is available for checking alignment without disassembling
the couplings. Check with your local Carrier representative.
Doweling for Open-Drive Machines
The size, quantity, and location of dowels vary considerably with type and arrangement of
gear and drive. Check your job data for specific doweling instructions. Typical doweling
practices are described in the Maintenance section.
Never operate compressor or drive with coupling guards removed. Serious injury
can result from contact with rotating equipment.
