WHAT WE DO

Services Built for South African Businesses

Diesel Engine Overhaul and Engine Rebuilds

We fully remanufacture diesel engines back to original specification. We work across a wide range of brands including John Deere 4045 and 6068, Cummins 6BT and QSL9, Caterpillar 3054C, C4.4, C11, C15 and C18, Mitsubishi, ISUZU, JCB, Deutz, Weichai, Doosan, and Tata. Every rebuild includes reconditioned injectors, turbochargers, and diesel pumps. All engines are Dyno Tested before leaving our workshop. Contact us to discuss your engine rebuild.

Hydraulic Component Repairs

When your heavy plant loses hydraulic power, productivity stops. Our team diagnoses and repairs hydraulic systems on excavators, TLBs, dozers, front loaders, and other heavy machinery. We restore full pressure, flow, and cycle performance so your machine works the way it should. We serve clients across Gauteng including Johannesburg, Pretoria, and surrounding areas. WhatsApp us on 074 5783 032 to get your hydraulics assessed.

Turbocharger and Injector Pump Reconditioning

A worn turbocharger or faulty injector pump costs you fuel, power, and time. We recondition turbochargers and diesel injection pumps to restore the fuel efficiency, power output, and emission compliance your engine needs. This service is included in every full engine overhaul we perform, and also available as a standalone repair. If your machine is smoking, losing power, or struggling to start, get in touch with CMKT Engineering and Projects today.

Field Breakdown Response

When a machine goes down on site, you cannot always tow it to a workshop. CMKT Engineering and Projects dispatches directly to your location to diagnose and repair the machine in the field. We cover construction sites, mining operations, and roadworks across Gauteng and surrounding areas. Getting your machine back to work quickly is our priority. Call or WhatsApp us on 074 5783 032 and we will get to you as fast as possible.

Fleet and Machinery Servicing

Keeping your fleet on a proper service schedule prevents expensive failures and unplanned downtime. We carry out scheduled servicing for plant, construction equipment, and commercial vehicles, keeping everything within manufacturer service intervals. Whether you run two machines or twenty, CMKT Engineering and Projects can set up a servicing plan that works around your operations. Contact us to arrange a fleet servicing schedule across Gauteng.

Engine Dynamometer Testing

After every engine rebuild we carry out full Dyno Testing to verify power output, torque, oil pressure, operating temperature, and emission compliance. This means you get an engine back that has been proven to perform before it goes back into your machine. No guesswork, no surprises on site. Engine Dynamometer Testing is standard practice at CMKT Engineering and Projects. Ask us about our rebuild and test process when you get in touch.

Transmission Repairs

Gearbox and transmission failures on heavy plant and commercial vehicles can bring your operations to a standstill. Our team diagnoses and repairs transmission systems across a range of heavy machines and vehicles. We identify the root cause, carry out the repair, and get the machine back to full working condition. If your machine is slipping, not selecting gears, or making unusual noises, contact CMKT Engineering and Projects in Gauteng for a proper assessment.

Machine Work and Engineering Machining

Precision machining is at the core of a proper engine rebuild. We carry out engineering machining on cylinder heads, engine blocks, crankshafts, and connecting rods to exact tolerances. This work ensures rebuilt engines perform the way they should and last the way they should. CMKT Engineering and Projects has the equipment and skill to machine components that other workshops would simply replace. Talk to us about your machining requirements across Gauteng.

Plant Hire with Free Loan Guarantee

We hire out TLBs, excavators, dozers, bobcats, 10 cubic tipper trucks, 10 ton rollers, crushers, front loaders, and water trucks across Gauteng. Short term, long term, and custom rental plans are available with on site delivery.

Real Results. Real People.

“

Our Cummins QSL9 on a SANY excavator seized up mid-project and we were looking at serious downtime. CMKT stripped it, rebuilt it, and had it back to us Dyno Tested within the timeframe they promised. The machine has been running strong ever since. These guys know what they are doing and they do not waste your time.

What impressed me most was that they offered us a replacement TLB from their own fleet while ours was being repaired. No other workshop I have dealt with does that. They finished on time so we did not even need to test the free hire guarantee — but just knowing it was there took the pressure off completely

We needed a 10 ton roller and a tipper truck for a roadworks contract on short notice. CMKT had both available, delivered on time, and the equipment was in good working condition. The rental terms were straightforward and the communication was excellent throughout. We will definitely use them again for our next project.
