Governor issue limiting power

Governor issue limiting power

No doubt you’re familiar with the function of the governor on your engines. And you might also be aware of what can happen when a governor has been incorrectly set up – we were certainly reminded of it the other day. We had a Deutz BF6M1013 engine on test after a rebuild, where it was producing 230hp, instead of the required 279hp. The engine had been built from a donor unit after the original engine suffered a broken crankshaft along with the...

Black Smoke & High Temperatures

Black Smoke & High Temperatures

We had a request for technical support onboard a major shipping company’s vessel this week. The Fleet Superintendent got in touch with us to report that one of their MAK 8M20 engines started experiencing high exhaust temperatures and producing black exhaust smoke. As well as logging temperatures and pressures, they had already completed some of their own investigations, including: • Check Scavenge Air Cooler – Found to be very dirty. The client...

Cylinder Identification

Cylinder Identification

During a recent job, we realised that the cylinders on the engine had been misidentified. It reminded me of a much more serious problem we’ve seen before, which you can see in the picture below. All this was as a result of the A-bank pistons being fitted in the B-bank and vice versa. Not only is it critical to return the pistons to the correct bank of the engine, but when it comes to communicating, resolving and recording engine information, it...

Unsalvageable Cat 3408 Engine

Unsalvageable Cat 3408 Engine

We’ve recently received two sets of critical CAT 3408 engine spares from an operator. Their previous service company advised them that they were either unsalvageable or out of spec & would require repairing – at an eye-watering high cost. Before taking this costly step, the operator decided to send the parts to us to inspect for a second opinion. The parts arrived at Bartech completely stripped & on multiple pallets. A lot of the parts...

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

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. Once on the vessel, we checked the backlash of the timing gears and found them to be out of tolerance, and the result was this damage to the teeth on the gears: The engine arrived in our workshop, where we...
