Engine

1.1 Coolant level: Insure level to base of fill neck, check "services required" if you add more than a half gallon
1.2 Engine oil level: Insure oil level is at full mark on the dip stick. Replace at 300hrs. Or when ever contamination is present.
1.3 Hydraulic oil level: Fill tank to appropriate level. Drain any condensation before filling.
1.4 Air intake piping: no unplugged holes, loose or missing clamps, & no visible leaks.
1.5 Cooling fan belt condition & tension: Inspect for cracks, frays, & excessive stretch or wear. Replace if needed.
1.6 Radiator: no leaks, no fin contamination to cause air flow restriction, steam clean as requires, shroud intact and mounting bolts tight.
1.7 Oil & Fuel filter condition: Replace at 300 hrs or when rusted, leaking, dented, or bad fuel is present.
1.8 Fuel, Air,& Hyd. Tank condition: Inspect all for rust, dents, cracks, leaks, vents, caps, and valve defects.
1.9 Air, Fuel, Hyd. Hoses: Inspect all hoses for damage, wear, leaking, excessive rust, or cracks. Replace as needed.
1.10 Diesel level: Insure there in not < than 1/2 of a tank. Drain any condensation.
1.11 Engine oil pressure: Not less than 15 psi with engine at idle, not less than 50 psi with engine running full throttle.
1.12 Gauges & Indicators: Must work from zero to full gauge range within limits of system being measured.
1.13 Hyd Quick couplings: Check for leaks, excessive corrosion, non-standard size/style will require repair or replacement and retest.
1.14 Air compressor @ full charge: 115-125 psi, must hold post SD for minimum of 30 minutes with valves open, not > than 10% loss allowed.
1.15 Air intake filter: Indicator should be below 20 in. Vacuum with engine running at full throttle, replace filter if indicator is in red area or if 25 in. Or more of vacuum is measured with engine running at full throttle, retest after replacing filter.
1.16 Coolant temperature: OEM spc of 200 deg. Operating temperature.
1.17 Check for exhaust leaks: Check for any leaks and /or defects. Repair or replace if needed
1.18 Fuel/Oil/Coolant Leaks: Observe very closely all hoses, piping, couplings, pump, and radiator for visible leaks of principle engine liquids, none are to be allowed.
1.19 Air compressor mounting: Bolts tightened to OEM specs.
1.20 Fan hub: No bearing deflection allowed, check for deflection with belt tension release, replace worn bearings, and grease with no more than 3 shots.
1.21 Guards and covers: Radiator, drive shafts intact, in place properly fastened, inspected for structural integrity.
1.22 Exhaust brackets/guards: Inspect for rips, tears, loose or missing bindings or blankets must be replaced.
1.23 Air Intake Vacuum restrictor: Indicator should be reset to 0 vacuum with engine off, replace defective vacuum indicator, and recheck vacuum after replacing indicator.
1.24 Fuel pressure: 50-60 psi @secondary filter. Check while engine is running at full throttle.
1.25 Throttle operation: Idle to full rev functionality via twist type air assist control valve.
1.26 Engine kill system: "normal" kill button when depressed must immediately shut off fuel air supply killing engine the engine completely.
1.27 Engine kill system: "Emergency" kill button when depressed must immediately shut off air supply and killing the engine completely.
1.28 Post job engine hours
