Carlyle Compressor Reciprocating Compressor 06DM3130

Warning: This procedure requires trained personnel with PPE!

Is the compressor with metal core gaskets?

If the compressor is with metal core gaskets, stop the procedure

Did the cylinder head and fiber valve plate gaskets develop a set?

Enter the discharge gas temperature

Did the gear cap screws lose hold-down torque?

Retorque all gear cap screws 24 hours after new fiber gaskets are installed

REMOVE, INSPECT AND REPLACE CYLINDER HEAD AND VALVE PLATE ASSEMBLY

To test for leaking discharge valves or blown cylinder head or valve plate gaskets:

2. 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.

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

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?

Warning: This procedure requires trained personnel with PPE!

Does the oil pump require replacement?

Does the pump end bearing require replacement?

Select the type of refrigeration application

Enter the part number for 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.
