The best processes for engine work

The best processes for engine work

One of our company values is continuous improvement and we’ve recently taken on a new member of the team to improve on one specific area that I think is relevant for any operator. Two weeks ago, John started with us on a STEP placement to review and develop our engineering Standard Operating Procedures (SOPs). Having been trading for 32 years, we already have plenty of experience on how we look after critical engines, so why do we feel the need...

Turbocharger Damage

Turbocharger Damage

We have two ABB VTC 254-13 turbochargers being overhauled in our workshop and they both offer a stark reminder of what could be going on, unseen, in many operational turbos. I haven’t got information on the history of these turbochargers, but they’ve been sent to us as part of an engine overhaul and I thought it was worth sharing what we found: • Considerable damage to the compressor wheel blades.

It was obvious there was a problem when we removed the injectors for a borescope inspection on these Mirrlees Blackstone engines and found a pool of coolant on top of the piston. Looking into the cause, we found the injector tube had cracked, and the...

Engine vibration damage

One of our client’s Deutz DFP6 1013 C20 fire pumps failed the other day, and our engineer Andy has been looking into the root cause.And what he’s found is a great example of how much damage can be caused even on low hours engines and how it can be prevented.The engine arrived at Bartech after excessive movement was found on the crankshaft, and an assessment was needed to see if the engine could be repaired, or if a replacement was...
