Ariel Heavy Duty Balanced Opposed Compressor JGP/2

Warning: Ensure all power to the Unit is shut off and the Tank is drained of air pressure before servicing the Air Compressor.

Insist on Genuine parts and kits when maintaining your Compressor Unit and Pump.

Hot alignment check at coupling within 30 minutes performed?

Fastener torque on gas nozzle flange, valve cap, cylinder head, compressor rod; packing flange and, if applicable, crosshead guide to frame bolting checked?

Bearing temperatures and crankcase visual inspection performed?

Lubricator block cycle time checked?

Check crosshead pin to crosshead pin bore and connecting rod bushing bore by removing crosshead pins.

Check for excessive wear in the auxiliary end drive chain tightener.

Check for excessive ring groove wear in pistons.

Drain and replace lubricator box oil.

Change oil filter or when oil filter differential pressure exceeds the filter change value.

Clean sintered element in the small oil filter supplied on the force feed lubrication system or every time main oil filter is changed.

Clean strainer when oil is changed.

Open frame when oil is changed and visually inspect for foreign material.

Check fluid level in torsional vibration damper (if applicable). Take fluid sample for viscosity testing.

Re-tighten hold down stud-nuts to proper torque values.

Realign if necessary to hold coupling hub face and rim hot alignment within 0.005 inch (0.13 mm) TIR.

Safety First! Ensure the compressor is shut down and the gas system is vented before starting.

Fastener torque on gas nozzle flanges, valve caps, cylinder heads and compressor rod packing flanges checked and confirmed?

Fasteners that turn at the first month check, should be re-checked after the second month or 1300 hours. If loosening persists, consult your packager or Ariel to help determine the cause and recommend the correction.

Safety shutdown functions checked and confirmed?

Upload the frame oil sample analysis report

If the oil analysis results indicate, change oil. If an oil analysis indicates lead, tin or copper particles in the oil, check main, connecting rod and crankshaft-thrust bearing clearances.

Bearing clearances checked and within limits?

Sign off on the compressor maintenance

Check main, connecting rod, and crankshaft-thrust bearing clearances with a pry bar and dial indicator.

Check crosshead guide clearance with feelers.

Inspect valves for broken plates and loose center bolts.

Inspect cylinder bores for damage or wear.

Inspect piston rods for damage and excessive wear.

Rebuild cylinder packing cases.

Check and re-calibrate all temperature and pressure gauges.

Check and record compressor rod run out.
