FOR MODELS: JGZ AND JGU SECTION 6 - MAINTENANCE INTERVALS & TROUBLE SHOOTING sis. See the Ariel Packager’s Standards or Technical Manual Lube Section for a listing of what an oil analysis should provide. 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. If bearing clearances are outside of the limits, replace the affected bearings. See the Ariel Technical Manual for instructions and clearance tolerances. Every 6 Months or 4000 Hours (plus Daily/Monthly) 1. Drain and replace lubricator box oil. 2. Change oil filter or when oil filter differential pressure exceeds the filter change value, see filter information plate on the top cover or Ariel Technical Manual, Lube Section for value. 3. Change oil. A more frequent oil change interval may be required if operating in an extremely dirty environment or if the oil supplier recommends it or if an oil analysis dictates it. A less frequent oil change interval may be allowed if the oil is replenished on a regular basis due to force feed lubricator usage. 4. Clean sintered element in the small oil filter supplied on the force feed lubrication system or every time main oil filter is changed. 5. Clean strainer when oil is changed. 6. Open frame when oil is changed and visually inspect for foreign material. Disassembly is not recommended unless a reason for it is found. 7. Check fluid level in torsional vibration damper (if applicable). Take fluid sample for viscosity testing. 8. Re-tighten hold down stud-nuts to proper torque values. Inspect for frame twist or bending to be sure the main bearing bores are in alignment. Check frame top cover mounting surface flatness tolerance and/or soft foot (reference Ariel document ER-82 or Technical Manual Section 2). For soft foot check, more than 0.002 inch (0.05 mm) pull down requires re-shimming. 9. Realign if necessary to hold coupling hub face and rim hot alignment within 0.005 inch (0.13 mm) TIR, except for hub O.D. >17 in. (>43 cm) angular face limit is increased to 0°1’ (0.0167°). 10. Check cylinders for the proper lubrication rates. Reference Ariel Technical Manual, Lube Section for a practical indication using the paper test method. Yearly or 8000 Hours (plus Daily/Monthly/6 Months) 1. Check main, connecting rod, and crankshaft-thrust bearing clearances with a pry bar and dial indicator. See the Ariel Technical Manual for instructions and clearance tolerances. Any time bearing clearances are outside the limits, replace the affected bearings. Disassembly to check clearances is not recommended. Disassembly should be performed if the pry bar check indicates excessive clearance. 2. Check crosshead guide clearance with feelers and if outside the limits listed in the Ariel Technical Manual, Clearances Table, replace the affected parts. 3. Inspect valves for broken plates and loose center bolts, replace broken parts and tighten center bolts. Reference Ariel Technical Manual, Fastener Torque 7/09 PAGE 6 - 3
FOR MODELS: JGZ AND JGU SECTION 6 - MAINTENANCE INTERVALS & TROUBLE SHOOTING Tightening Values or Toolbox Torque Chart, ER-63. 4. Inspect cylinder bores for damage or wear. If the cylinder bore surface is blemished or gouged, efficiency can be affected and/or rapid ring wear can result, or is more than 0.001 inch per inch of cylinder bore diameter (0.001 mm/mm) out of round or tapered, the cylinder body should be replaced or the bore restored. Contact Ariel for re-boring and bore restoration guidelines. 5. Inspect piston ring end gap. Replace rings that are outside the maximum limit listed in the Ariel Technical Manual, Clearance Tables. 6. Inspect piston rods for damage and excessive wear. If gouged or scratched, replace the rod. If the rod is more than 0.005 inch (0.13 mm) under size, out of round more than 0.001 inch (0.03 mm), or tapered more than 0.002 inch (0.05 mm) replace the rod. 7. Rebuild cylinder packing cases. 8. Check and re-calibrate all temperature and pressure gauges. 9. Check and record compressor rod run out. 10. Grease VVCP stem threads at grease fitting, with 2 to 3 pumps of multi-purpose grease using a standard hand pump grease gun. 11. Clean crankcase breather filter. 12. Adjust drive chains. 13. Pressure test distribution blocks. 14. Check gas nozzle flange, valve cap, cylinder heads, compressor rod packing, crosshead pin through bolt, crosshead guide to frame, crosshead guide to cylinder, cylinder mounting flange to forged steel cylinder, distance piece to cylinder, distance piece to crosshead guide and tandem cylinder to cylinder fastener torque. 15. If the compressor is equipped with crankcase over-pressure relief valves, inspect and exercise valves to the manufacturer’s recommendations. Every 2 Years or 16,000 Hours (plus Daily/Monthly/6 Months/ Yearly) 1. Check auxiliary end chain drive for sprocket teeth undercutting and chain for excessive stretching. 2. Rebuild oil wiper cases. Every 4 Years or 32,000 Hours (plus Daily/Monthly/6 Months/1 & 2 Years) 1. Check crosshead pin to crosshead pin bore and connecting rod bushing bore by removing crosshead pins. 2. Check for excessive wear in the auxiliary end drive chain tightener. 3. Check for excessive ring groove wear in pistons. PAGE 6 - 4 7/09
