As a break down mechanic:
I do major component change out, such as engines, torque converters, transmissions, differential assembly, wheel stations, hoist cylinders, suspension cylinders, hydraulic control blocks, tracks frames, down rollers idler segments, telescopic seals, track guard and tracks change out, pumps, cylinder head gasket, bucket pins, bearings. In doing major component change outs, this is the procedure used:
- Safety machine must be parked on level ground with parking break engaged, all wheels chocked hydraulic pressures released.
- Machine must be jacked for certain repairs removing of wheel station, working on a frame.
- Remove components that are in the way of actual component needed to be removed (for instance, radiator get to the engine) to get access to be component.
- Remove all hydraulic hoses attached to the component, remove cables harnesses if attached.
- Slack mounting belts and suspend the component before finally removing mounting belts, remove the faulty component.
- Clean the mounting surface, fix new seals, fix new component with crane or lifting gear, Put mounting belts in place, torque the mounting belts to manufacture specification, fix back all cable harness and fix back all hoses and pipes with new seals.
Field service troubleshooting:
- Consult machine operator to know what happened when the breakdown occurred.
- If it appears to be an engine problem, first step is to check engine oil, coolant and fuel levels, if ok, then check electrical system using ET (Electronic Technician) to diagnose the problem, when problem is detected, do rectification works according to manufacturer specifications.
