My responsibility is to attend to field breakdowns on the following equipment CATERPILLAR RIGID DUMP TRUCKS 785C, 777D, 777E and 777F Water trucks DOZERS – D375A, D475A, D9R and D10R ARTICULATED DUMP TRUCKS Volvo A40G and A40F water trucks and fuel Bowsers and finding lasting solutions to the following engine problems such as -diesel engine loss of power -engine or exhaust brake failure -engine fuel starvation -diesel engine low boost pressure -engine boost or intake air high temperature -engine low oil pressure and high temperatures -engine radiator fan overspeed -engine pressurized cooling system -engine overcooling and overheating heat transfer fluid -engine crankcase pressure -To make sure water trucks moulted spray systems is working up to standard if not adjusting hydraulic pressure, changing of electric switches and replacement of defective hydraulic pumps, hydraulic motors and stalker pumps same applies to fuel bowsers. It\’s only that fuel Browsers uses vane fuel pumps in place of stalker pumps -Problems of spring force activated piston applied and hydraulic pressure released park brake not releasing and holding on it\’s own -Hydraulic oil pressure applied and retract spring action(pulled) piston released service brake problems of not holding on Cat trucks 785C,777D,777E and 777F -Replacing defective relays valves,air flow control valves,compressors,governors, scavenge pumps,brake chambers and slack adjusters -On Volvo ADT\’s-air pressure released and spring applied park brake problems and hydraulic pressure applied and retract spring action(pulled) piston released service brake problems -Replacing defective compressors, solenoids valves,brake calipers,brake pads and brake boosters -Problems caused by defective heat exchangers of mixing heat transfer fluid with intake air and oils such as engine oil, transmission and hydraulic oil respectively -Blue, black and white engine exhaust color problems -Replacing defective intake air and oil coolers

Responded quickly to equipment breakdowns such as diesel motor problems -engine overheating -engine fuel starvation -diesel engines loss of power – engine boost or intake air high temperatures -engine brake failure -engine sensors malfunction -worn and brocken engine component parts – Blue, black and white engine exhaust color problems -Replacing defective aftercooler heat exchangers affecting combustion on Cat trucks 785C,777D and 777E -Replacing V8 and V12 cracked separate cylinder heads, worn sleeves, gaskets, oil and water seals to avoid engine hydrolock -Replacing defective engine, hydraulic and transmission oil coolers -Testing and adjusting air brake system -Major component change out such as engines, torque converters, transmission, differential and final drives following the correct standard procedure -Stripping and replacing worn brake discs and spacer plates for wet brake disc assembly -Stripping and replacing worn final drives dual cone seals to prevent brake cooling oil bypass into diff oil -Replacing defective torque converters, lockup clutches and solenoids -Replacing worn gear hoist pumps, scavenge gear type brake pumps and transmission gear type pumps -Reseal steering cylinders, hoist cylinders and hydro- pneumatic cylinders -Oil and Nitrogen charging of hydro- pneumatic cylinders -Replacing worn diff flange seals to prevent diff oil leaks -Promblems concerning -Drivetrain components failure -Hydraulic steering system failure -Upshift and downshift transmission failure -Braking system failure both wet and dry systems. -Hydraulic hoist system failure -Hydro- pneumatic cylinder failure. -Hydraulic system failure

Repaired Bomag, Bell, Caterpillar and Volvo Road construction machinery

Contributed to Zambia National Service during Lt gen Atony Yeta as ZNS commandant. ZNS is one of the Zambian defence forces in the ministry of Defence.
