Magnetic Pickup Probe Issue

Magnetic Pickup Probe Issue

Our engineers were on-site recently, carrying out a top-end overhaul on an emergency generator engine when they came across an issue that is often overlooked. But if left unchecked, it can drastically impair your engine’s performance. As part of the works, our team inspected the magnetic speed pickup… You can see from the picture below that the flywheel magnetic pick-up was covered in a 1mm depth of black dirt. The dirt on the probe was...

Excessive Engine Backlash

We’ve just started supporting a new marine operator, and the other day they were getting some concerning noises following the overhaul of their Caterpillar 3406 engine by another firm. As it turned out, a fundamental setting had been missed.

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 needed....

Excessive engine wear

Excessive engine wear

Our engineers are currently doing some servicing and rectification work on an MTU 396 engine, and I thought it was worth sharing some feedback from them. Whilst carrying out the inspection of the top end of the engine, they’ve come across the common problem of excessive wearing, which is a result of ineffective lubrication. I won’t go into detail about the important role lubricating oil plays in your engine; I’ve got no doubt you are well aware...
