We only play a small part in it all in the overhaul of the power units but the end result sometimes makes us stop and stare; hats off to everyone involved. What magnificent machines.

Firstly, I'd like to say a massive thank you to the team for working the bank holiday to keep things moving forward. These lads regularly go above and beyond for the sheer love of the job, and it's truly appreciated.

So, the big-end blocks have been stressed and measured to check for correct stretch, locking nutted and tabbed, awaiting the shims and conrods to join them.

The camshaft has been stripped, had the lobes cleaned, polished, and qualified, ready for the new shaft. The cambox has had a good clean and is awaiting the shaft and its new bearings.

Kaz has been machining the pistons, recording the new measurements ready for the final build.

We had some liners that needed freshening up; these were qualified, plateau honed, cleaned, and coated.

The RK280 heads that needed deep cleaning have also been completed, but we are still cycling the ones that needed the valve pockets and sealing faces machined.

The 275 heads have had all new plugs and seals, the valve pockets measured, and the valve seats measured and ground.

We also got the liners and sealing rings in the 275 to.

Feel free to give us a like share and follow

Small update from the week just gone:

It's been a tip-top week for us, returning to 44004 Great Gable for the Peak Locomotive Company to carry out an injector change. This took a little longer than anticipated when an injector hold-down stud snapped and required a V-coil. Once this was sorted, we ran it up. It was nice to hear her fire into life, and she sounds amazing. Hats off to the team at Peak Locomotive Company; they truly do put their hearts and souls into maintaining and keeping these old girls running.

The Mirrlees 275:
The big-end blocks have had their final checks and have been fitted (hand tight) to the power unit. We will stress these up Monday. The camshaft is in the process of being polished and having the bearing journals checked. The last of the pipework and also the electrical conduit is being cleaned and prepped for paint.

We overhaul any diesel/gas engine with vast knowledge of English Electric, Ruston, Mirrlees, Paxman, Sulzer, and M.A.N. Our workshop facilities have five overhead cranes, chemical cleaning baths, crank/camshaft baths, shot blasters, and lathes, etc.

We have strong connections to obtain and supply parts and information within the diesel industry.

We can major overhaul and hold around seven power units at a time (Ruston 270 RK size) and aim to turn around one power unit in approximately four to six months, depending on its state on arrival. Our capacity is dependent on ongoing workload but can be ramped up depending on the size of the contract.

We also overhaul any component, i.e., cylinder heads, cylinder liners, oil pumps, water pumps, crankshafts, camshafts, overspeeds, etc. We partner with other trusted companies for crankshaft grinding and modification, specialist machine work, and processes, i.e., metallurgy work. We can custom-make and approve oddity parts that are no longer available.

We can also provide consulting and solutions for overhaul/maintenance programs, emissions, fuel, and oil consumption, as well as fault failure investigation and reports on findings. We also work with other companies to help them with design, test, and overhaul procedures, etc.

As well as workshop overhauls, we can offer site support and repair work if required.
