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...

Dropped Valve Seats

Dropped Valve Seats

During the overhaul of a generator package, we came across an issue that could’ve been costly to our client. As standard, we removed & dismantled the cylinder heads, including the valve seats. However, the process for the seat removal (to heat each head to 220°C, then remove the valve seat & install the new one before the head can cool) doesn’t allow time to measure the valve seat bores. With aluminium heads, the new seats...

Emergency Generator Offline

Emergency Generator Offline

A couple of weeks ago, we were asked to survey some Blackstone engines. The engines are an emergency power system, so they’re absolutely vital for the site’s safety system.  All three engines had various issues, but there was a familiar one which had gone unnoticed and came to light as soon as we started engine 1. As soon as the engine turned over, fluid started leaking from the top of it. We stopped it straight away, and checked the fluid,...

Caterpillar 3512 Cracked bedframe

Caterpillar 3512 Cracked bedframe

Our engineer, Matt, has just returned after supporting an operator in the Caspian Sea with the overhaul of their Caterpillar 3512 generators. Whilst working with some local engineers who had begun dismantling the engine, they showed him something they had found which required urgent attention. This is something we have come across many times before and seems to be a recurring issue, though with different causes, different damage and...

Engine overhaul changes

Engine overhaul changes

We’re currently overhauling a complete generator set in our workshop. It’s one of four identical sets owned by the operator, and like a lot of operators, they usually operate under a service exchange programme, where one engine is replaced with another after a specified period of time. This time though, they’ve thought differently about the work scope to reduce the costs and disruption. As a complete package, we are responsible for the overhaul...
