TM 5-3810-207-20/TO 36C23-3-37-12ItemBefore starting engineParagraph11Crane winterization equipment-radiator shutter, batteries, heater control panel, cabheater, thermostat, defroster, windshield wiper, motor, cab insulation, heater fuelpumps, lines, and filters, coolant pump, coolant heater safety relief valve, coolantheater, space and coolant heater igniters, coils, and relays, battery box, thermostatcontrol, and heater piping. Inspect these items for wear, leaks, damage, breaks,missing parts, and operation.Start engine12With engine running at normal operating temperature, listen for unusual noises; inspectcylinder head, manifold, exhaust pipe, muffler, and gaskets for leaks. Check governorlinkage for excessive wear and proper operation under varied loads. Check engineclutch for proper operation. Inspect fuel and oil lines, hydraulic system, and fuel andoil filters for leaks. Check all gages, instruments, and controls for proper readings andoperation. Normal gage readings are:Crane:Ammeter ...............................................................+0-60 ampCoolant temperature..............................................180°F. (Fahrenheit)Oil pressure...........................................................40-50 psiCarrier:Oil pressure warning light ......................................Out, with engine runningCoolant temperature..............................................160-180°F.Air pressure...........................................................80-105 psiOil pressure...........................................................40-50 psiCoolant temperature warning light .........................Out, with engine at normaltemperatureBattery generator indicator ....................................In green areaOperational test13Engine-during the operational test, notice in particular if the engine has normal power,proper acceleration in varied speed ranges, tendency to stall. Listen for any unusualnoises when engine is under load. Look for excessive black or blue smoke fromexhaust.14Carrier transmission, differentials, transfer case, clutch, and brakes. Check for clutchbraking effect, vibration, and clutch engagement. All forward and reverse speedranges. Notice If all shifts are smooth and without vibration or unusual noises. Checksteering mechanism, operating controls, and brakes for proper operation andadjustment.15Check carrier instruments, gages, switches, horn, and lights. Notice if lights are correctlyaimed and securely mounted.16Crane master clutch, swing clutch, hoist clutch, boom hoist clutch, crowd and retractclutches, and brakes. Check for proper engagement, and operation. Notice if clutcheschatter or vibrate excessively. Check brakes under load for proper operation andadjustment. With crane machinery operating listen for unusual noises in the hoist,crowd, jack, and swing shafts. Listen for unusual noises in the power transfer case andchain drives.After-operational test17Temperatures-carrier transmission, differentials, transfer case, clutch housing, craneclutch housing, power transfer case, bearing housings. Immediately after operationaltest, inspect these components for excessive heat. An overheated housing indicatesinternal maladjustment, damage, or inadequate lubrication.18Leaks-engine oil, fuel, water, hydraulic system, transmission, differentials, transfercases, grease seals, and gaskets. Inspect the equipment for fuel, coolant, lubricant,hydraulic fluid leaks from seals, gaskets, lines, hose connections, radiator, fuel tanks,or other sources.19Check identification plates, paint, and marking for condition and secure mounting.20Service and lubricate in accordance with LO 5-3810-207-20.19
