KOMATSU GD650 MOTOR GRADER REPAIR PROCESS

Komatsu GD650 Motor grader repair process The extensive Delta repair process incorporates a thorough evaluation involving more than 300 tests and inspections. Critical torques, clearances and pressure settings are measured, adjusted if necessary and recorded. Thanks to the Delta repair process, we are able to provide a reliable machine which looks like new at a fraction of the cost of buying new. WARRANTY

Protect your investment! Please ask for Delta warranty options. Below you find a snapshot of the inspections and repairs that are carried out: Delta repair process comprises: • Physical inspection • Technical inspection/repairs; • Engine • Cooling system • Transmission/Power train • Hydraulic system • Electrical system • Frame and body • Operator station • Tyres • Performance testing • Sandblast/Painting • Delivery • Options • Parts availability Physical inspection: This vital first step is a thorough inspection of the machine which enables us to make a cost estimate for repair. A comprehensive evaluation determines the specific needs of the machine. After the inspection, we thoroughly clean the machine and meticulously remove all exterior dirt and grime using a high pressure, warm water jet.

Engine: - Compression of each cylinder is tested to ensure it meets the manufacturer’s specifications, if the compression test does not meet these specifications, we overhaul the engine. - Fuel injectors are tested; if they do not meet the manufacturer’s specifications, they are replaced with new fuel injectors. (this is a non-electronic engine!) - Turbocharger is checked and measured; if the measurements do not meet the manufacturer’s specifications, the turbocharger is replaced with a new one. - Exhaust manifold is checked; if it shows any malfunction, it is replaced with a new one. - Engine oil pressure is checked to ensure it meets the manufacturer’s specifications. - Drive belts are checked and replaced if necessary.

Transmission/Power train: - Torque converter pressures are measured; if measurements do not meet the manufacturer’s specifications, we replace or overhaul the torque convertor. - Transmission pressures are measured; if measurements do not meet the manufacturer’s specifications, we replace or overhaul the transmission.

Hydraulic system: - Hydraulic pump pressures are measured; if the pressures do not meet the manufacturer’s specifications, we replace or overhaul the hydraulic pump. - All hydraulic cylinders are checked; if a cylinder shows extensive damage, it is replaced by a new cylinder. - All seals of the hydraulic cylinders are checked; if any seals leak, they are replaced with new one. - All hydraulic hoses are checked; if any hose leaks, it is replaced with a new one.

Tyres: - All tyres must have at least 70% tread profile remaining or they will be replaced with new ones.

Performance Testing: Quality Control is integral to our repair process. Rigorous operational testing is conducted after all repairs to ensure field performance. The tests routinely performed include throttle response, stall speed rpm, transmission response, hydraulic and pilot relief valve pressures and other general functional test such as steering- and brake performance. Instrumentand operational tests are also conducted to ensure field performance levels match those achieved in the shop.

Sandblast/Painting: Once the machine has been thoroughly tested, it receives a top quality paint job. After a complete 2-coat paint job in our own professional paint facility, new identity graphics are applied to ensure the grader looks new.

Delivery: A professional Delta pre-delivery inspection is carried out by our technical staff before shipment to customers to safeguard the job-ready status of our machines. All Komatsu motor graders supplied by Delta include parts, workshop and operators manuals.
