EngineDisassembly and Assembly9.To avoid back injury, use a hoist when liftingcomponents which weigh 50 lb. (23 kg) or more. Makesure all chains, hooks, slings, etc., are In good conditionand are in the correct capacity. Be sure hooks arepositioned correctly. Lifting eyes are not to be sideloaded during a lifting operation.10. To avoid burns, be alert for hot parts on machineswhich have Just been stopped and hot fluids In lines,tubes and compartments.11. Be careful when removing cover plates. Graduallyback off the last two bolts or nuts located at oppositeends of the cover or device and pry cover loose to relieveany spring or other pressure, before removing themcompletely.12. Be careful when removing filler caps, breathers andplugs on the machines. Hold a rag over the cap or plugto prevent being sprayed or splashed by liquids underpressure. The danger is even greater if the machine hasjust been stopped because fluids can be hot.13. Use only the recommended tools which are listed fora specific procedure. Be sure the tools are In goodcondition and that you fully understand how to use thembefore performing any service work. Failure to use thelisted tools can cause damage to components or seriouspersonal injury or death.14. Reinstall all fasteners with same part number. Donot use a lesser quality fastener if replacements arenecessary.15. Repairs which require welding should be performedonly with the benefit of the appropriate referenceinformation and by personnel adequately trained andknowledgeable in welding procedures. Make referenceto "Techniques of Structural Repair Course" formnumber JEG03719. Determine type of metal beingwelded and select correct welding procedure andelectrodes, rods or wire to provide a weld metal strengthequivalent at least to that of parent metal.16. Do not damage wiring during removal operations.Reinstall the wiring so it is not damaged nor will it bedamaged in operation by contacting sharp corners, or byrubbing against some object or hot surface. Do notconnect wiring to a line containing fluid.17. Be sure all protective devices including guards andshields are properly installed and functioning correctlybefore starting a repair If a guard or shield must beremoved to perform the repair work, use extra caution.18. Always use lift arm supports to keep bucket armsraised and bucket tilted down when maintenance orrepair work is performed which requires the bucket in theraised position.19. Loose or damaged fuel, lubricant and hydraulic lines,tubes and hoses can cause fires. Do not bend or strikehigh pressure lines or install ones which have been bentor damaged. Inspect lines, tubes and hoses carefully.Do not check for leaks with your hands. Pin hole (verysmall) leaks can result in a high velocity oil stream thatwill be Invisible close to the hose. This oil can penetratethe skin and cause personal injury. Use cardboard orpaper to locate pin hole leaks.20. Tighten connections to the correct torque. Makesure that all heat shields, clamps and guards areinstalled correctly to avoid excessive heat, vibration orrubbing against other parts during operation. Shieldsthat protect against oil spray onto hot exhaustcomponents in event of a line, tube or seal failure mustbe installed correctly.
