Injector tube supersession

Recently we were completing the health check and maintenance routine on one of four back-up generators and found the result of problems caused because a much-needed upgrade hadn’t been carried out. 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...

Caterpillar crankshaft damage to threads and bolts

Caterpillar crankshaft damage to threads and bolts

We’re supporting a client who is overhauling 4 Caterpillar 3512 generator sets at the moment, and we got the email below from them this morning… There is a translation error in that this is an issue with the crankshaft and not camshaft, but this is where the beauty of photographs can help! Our advice was to helicoil the damaged threads (which is a recognised process by the OEM), though there are certain considerations in carrying out this...

Cummins KTA50 emergency generator performance and parts supply

Cummins KTA50 emergency generator performance and parts supply

An offshore client contacted us last week as they were experiencing issues with their Cummins KTA50 emergency generator performance. Once the engine was up to running speed and the running light illuminated, the engine kept accelerating. Shortly after this, the vent flaps tripped and the engine rapidly slowed down to below idle before stopping completely – all within 30 seconds. After a few conversations to gain all the information surrounding...

MTU genset issues and record keeping

MTU genset issues and record keeping

Last week one of our MTU trained engineers, Matt, headed out with his laptop, complete with DiaSys diagnostic software. He was tasked with looking at a couple of MTU 20V4000G62 generator sets, which were having various problems with alarms, hunting and synchronisation. Once Matt got onsite, he started to look at the hunting and synchronisation issues on the first set by connecting up the laptop to see what information there was from the MDEC....

Deutz generator with dangerous oil pressure caused by cold weather

Deutz generator with dangerous oil pressure caused by cold weather

This week we had a stark reminder of the importance of making sure your engine oil is kept at the right temperature. We’d completed the overhaul of a Deutz driven generator package and prepared the unit for the first test run. And during that first test run, there was a problem. As part of the preparations, the oil heaters were left on for 8 hours, but when the engine started, it only registered around 20 Psi pressure, so was shut down within...

Mirrlees ELS12 generator set drop in oil pressure

Mirrlees ELS12 generator set drop in oil pressure

Last week we were called to the site of a Mirrlees ELS12 generator set, and there’s no prizes for guessing what the issue seemed to be. Once Cris arrived on site and went about looking into the reported problem, he found there was no issue with the engine’s oil pressure. Instead, there was a problem with the feedback of information to the panel. For this setup, the engines rely on Amot switches as part of the warning system As he...
