Carlyle Compressor Reciprocating Compressor 06DR0130

Warning: This procedure requires trained personnel with PPE!

Is the application high compression ratio?

If the application is not high compression ratio, stop the procedure

Are new fiber gaskets installed?

If new fiber gaskets are not installed, stop the procedure

Does the compressor have metal core gaskets?

If the compressor has metal core gaskets, stop the procedure

Enter the current hold-down torque of the gear cap screws

Did the gear cap screws maintain the required hold-down torque after 24 hours?

Warning: This procedure requires trained personnel with PPE!

Enter the part number for replacement

Select the type of refrigeration application

Is the high side oil safety switch connection included in the package?

Sign off on the pump and bearing replacement

Warning: This inspection requires trained personnel with PPE!

After 2 to 4 hours of operation, inspect compressor oil for discoloration and/or acidity.

Does the oil show signs of contamination?

If oil shows signs of contamination, replace oil and filter-driers and clean the suction strainer.

NOTE: When testing for moisture and acidity, be sure the test kit used is appropriate for the refrigerant (CFC, HCFC, or HFC) and the oil (mineral, alkylbenzene, or POE) in the system.

Select the type of refrigerant used

Carrier’s Total Test Kit is accurate for CFC and HCFC air-conditioning applications. If used with POE oils, Total Test Kit will indicate acid, but is not an accurate indicator of moisture.

Sign off on the motor inspection

Warning: This maintenance check requires trained personnel with PPE!

Oil pressure tap in the bearing head assembly present?

Oil pump assembly contained in the pump end bearing head aluminum casting?

Pump end main bearing is a machined part of the casting?

Upload a photo of the bearing head cover plate after removing four (4) cap screws

Upload a photo of the oil feed guide vane and spring after removal

Upload a photo of the end of the crankshaft after removing two (2) drive segment cap screws

Drive segment cap screws removed before the bearing head removal?

REMOVE, INSPECT AND REPLACE CYLINDER HEAD AND VALVE PLATE ASSEMBLY

Observe suction and discharge pressure equalization.

If valves are leaking or a gasket is blown, the pressure will equalize rapidly.

Maximum allowable discharge pressure drop is 3 psi per minute after initial drop of 10 to 15 psi in first half minute.

New reed valves may require 24 to 48 hour run-in time to seat completely.

A compressor bank (head) with a blown gasket can also usually be detected by touch since the head temperature will normally be much hotter than a bank with good gaskets.

If there is an indication of loss of capacity and discharge valves are functioning properly, remove valve plate assembly and inspect suction valves.

NOTE: This test procedure is not applicable to compressors equipped with pressure actuated unloader valves due to rapid pressure equalization rate. Inspect suction and discharge valves by disassembling valve plate.
