400 VMC series compressor Operation and service manual
VILTER MANUFACTURING CORPORATION VILTER Multicylinder Compressor OPERATING INSTRUCTION MANUAL 400 SERIES COMPRESSORS READ CAREFULLY BEFORE INSTALLING AND STARTING YOUR COMPRESSOR. The entire manual should be reviewed before attempting to install, service or repair the compressor. A refrigeration compressor is a positive displacement machine. It is designed to pump superheated vapor. The compressor must not be subjected to liquid carry over.
Vilter Stop/Check-Valve General Information AUTO In the “Auto Position”, the stop valve is operating as a check valve, allowing flow in the directions of the arrows. To set the valve to the automatic position, fully close the valve, and turn the stem out as indicated by the chart below. CLOSED In the manually “Closed Postion”, the stop check is operating as a convientional stop valve, not allowing flow in either direction.
Verify the location of Spring and note the direction of the Vilter name Installation: The new design will apply only to the 2” thru 4” stop valves. Retrofitting a field installation will require replacing the bonnet assembly. The bonnet must be installed with the spring towards the bottom (see illustrations above). The drill fixture is designed so that the hole for the spring will always be drilled on the opposite side from the cast in Vilter name on the bonnet.
Master Catalog Pressure Controls Section Product/Technical Bulletin Issue Date 125 P P28 0498 P28 and P128 Series Lube Oil Controls with Built-in Time Delay Relay The P28 and P128 Series Lube Oil Controls provide dependable and economical oil pressure cut-out for pressure-lubricated refrigeration compressors. The field-adjustable pressure differential of these controls provides compressor operation according to the manufacturer’s specifications.
I ntroduction ! Dimensions WARNING: Personal injury hazard. All P28 and P128 controls are designed as lubrication protection controls. Failure of the P28 or P128 could allow the refrigeration compressor to be damaged in a way that may not be apparent upon visual inspection. Follow proper procedures and the compressor manufacturer’s instructions, as well as any warning signs on or around the equipment, when discharging and disassembling the compressor. Environmental damage hazard.
Example: Net oil pressure (oil pump pressure minus crankcase pressure) required to the bearings is 9 psi (62 kPa). The control scale setting should be 9 psi (62 kPa). The switch differential is 5 psi (34 kPa). Upon initial start of the compressor, the time delay relay energizes. If the net oil pressure does not build up to 14 psi (97 kPa), or the scale setting (9 psi) plus the switch differential (5 psi), during the time delay, the control breaks the circuit to the compressor.
See Figures 3 through 10 for typical wiring diagrams or refer to the compressor manufacturer’s specifications. When a P28 or P128 is installed on a 440 or 550 VAC system, use an external step-down transformer to provide either 120 or 240V to the pilot and time delay relay circuits. The transformer must be of sufficient volt ampere capacity to operate the motor starter and the time delay relay. Table 1 presents the power requirements for the P28 or P128 time delay relay.

OPERATION WARRANTY HCK4 check valves are normally closed valves. As inlet pressure increases, it overcomes the closing spring force. As the seat disc is pushed back and away from the seat cartridge, flow through the valve occurs. The valve will remain open until the inlet pressure drops below the closing spring force or there is a flow reversal, at which time the seat disc will close against the seat cartridge, preventing reverse flow.
SECTION A1 WOOD’S SURE-GRIP QD BUSHINGS TM • Provide a True Clamp Fit • Are Easy to Install and Remove • Permit Four-Way Mounting A1–1
SURE-GRIP BUSHING FEATURES Sure-Grip® “Quick Detachable” bushings are easy to install and remove. They are split through flange and taper to provide a true clamp on the shaft that is the equivalent of a shrink fit. All sizes except JA and QT have a setscrew over the key to help 6-hole drilling (most sizes) makes installation and removal quick and easy. Precise taper (3/4 in. per ft. on diameter) provides proper wedging action.
SURE-GRIP BUSHING DIMENSIONS Sure-Grip bushings are designed to transmit the rated torque capacity listed in the table below when the cap screws are tightened as indicated. The bushings are stocked in all popular bore sizes, including metric bores, within the bore range for a particular bushing.

VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor 5. Drive Installation (cont’d) assembly. As the anti-seize is trapped when the parts are tightened, it will create a sliding layer between the parts. The parts are not free to move independent of each other while the unit is in operation, creating fretting corrosion. This results in excessive wear of the drive components and the possibility of the parts welding themselves together. The compressor, motor and base should be level.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor 6. amount of deflection should be 19/64” (7.54 mm) and the tension required to achieve it should be between 12 to 18 lbs. Drive Alignment (cont’d) Vertical angular misalignment results when the motor and compressor shafts are in the same vertical plane, but not in the same horizontal plane. A straight edge is held against the compressor pulley face. The distance from the straight edge to the motor sheave at the top and bottom is compared.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor A straight edge is positioned across the sheave and flywheel to use as a reference to measure the deflection of the belts. Inspect the compressor coupling bore and crankshaft to make sure they are clean and free of burrs. Apply anti-seize to shaft and coupling bore. Place the key on the shaft and slip on the coupling. Install the bolt (and washer, if required), and tighten.

Replace ring set carefully with a new one every time a piston is removed. With eyebolt removed, place the piston into its hole in the frame.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor VII. OIL PRESSURE ADJUSTMENT ASSEMBLY A. Disassembly The oil pressure adjustment assembly is located in the front bearing housing. It consists of a spring loaded ball positioned in a machined seat in the top of the front bearing housing. An adjusting screw turned in and out changes the amount of oil bypass, thus changing the oil pressure. Remove the cap. A packing tool is required to remove the gland nut (Vilter Part No. A33781A).

PREPARATION FOR INTERNAL SERVICING NOTE: Before proceeding, refer to Paragraph I, “General Service Instructions”. A. Removal A. Handhole Cover Removal To remove the oil pump assembly, first remove the filter tank and adapter from the rear housing. Be prepared for a small amount of oil to drain from adapter.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor heater wiring and heater cover, add oil to crankcase and turn on power to the heater to preheat the oil for operation of compressor. XI. CRANKSHAFT SEAL NOTE: Before proceeding, refer to Paragraph I, “General Service Instructions”. A. Oil Seal Leakage In refrigeration compressors, a slight amount of oil leakage past the crankshaft seal is normal and desirable. A few drops per minute is reasonable. This leakage performs two important functions.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor 2. A. Disassembly After the cylinder covers, valves and handhole cover have been removed, the first step in removing the piston and rod assembly is to remove the Palnut® locknuts on the rod bearing bolts. Then, remove the plain nuts and slide the bearing cap off of the nuts. The Palnut locknut is not used with this type of locknut. Handle the bearing cap carefully to avoid damage to the bearing half insert.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor B. Reassembly (cont’d) The easiest way to replace the rings on the piston is to wrap a thin piece of shim stock around the pistons and slide the ring over this. Do not force the rings when sliding them onto the shim stock. The rings are brittle and may snap. A tool is also available to aid in the installation of the rings. Both compression and oil rings are marked to indicate the top of the ring.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor FIGURE 12.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor B. Reassembly (cont’d) Connecting rod bolts are secured with one plain steel nut and one spring steel locknut (commonly referred to as a “Palnut”). The plain nut tightening torque should be listed in Table 2, 3 or 4 (depending upon compressor model). The torque wrenches should be set to the high side of the tightening torque range.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor B. Installation Of Liners B. Lift Rings For Unloading There are two styles of unloading lift ring assemblies. 1. 440 Lift Ring Assembly Rotate the lift to align the notches with the pins. The springs will follow. The lift ring will then drop to the bottom of the liner. Note the position of each lift pin. They will have to be returned to that position for reassembly. Push the lift pins up and out of the top of the liner to remove them.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor A. General Removing the crankshaft from the compressor is basically the same for all units, regardless of size. Because of a center bearing on all 12 and 16 cylinder compressors and the radius the 8 cylinder throws on the crankshaft, an extra step must be taken. A crankshaft may be removed from either end of the compressor. It is, however, easier to take the crankshaft out of the drive end of the frame.
VILTER MANUFACTURING CORPORATION VILTER MultiCylinder Compressor bearing housing together. The bearing inserts are snapped into place and can readily be removed by pushing them out by hand. Clean the bearing housing thoroughly before installing new inserts. Snap the inserts into place. Lubricate the bottom half with refrigeration oil, and position it on the crankshaft. Do the same to the upper half, and locate it using the dowel pins provided.
