Precision Balancing Its All in the Detail!

Just 0.002 grams (2 milligrams) per balancing plane!

That's the incredibly fine indicated correction mass we're achieving on this turbocharger rotor assembly using our soft-bearing balancing machine.

But results like this don't happen by chance. They're the result of meticulous preparation, precision checks and attention to the smallest details long before the rotor reaches the balancer.

The real work starts long before the balancing process begins.

Before balancing, every rotor assembly is mounted in a dedicated jig fixture where runout is checked against our specified tolerances.

If the runout is outside our tolerance, the assembly is stripped back down and the components are carefully inspected to identify the cause.

Particular attention is given to locknut mating surfaces, collars, spacers, shaft shoulders and other mating faces. Even the smallest burr, contamination or surface imperfection can affect how components seat together and influence the final balance result.

Only once the assembly meets our runout requirements does it progress to the balancing machine.

And it's not just about achieving a low reading on the machine it's about achieving a result that's accurate, consistent and repeatable.

When you're dealing with turbocharger components operating at extremely high rotational speeds, the smallest details really do matter.

Precision balancing doesn't start at the balancing machine. It starts with the preparation.

A common issue we see with BorgWarner S300SX/S300SX-E turbochargers is exhaust leakage from the turbine outlet fl**ge.

These turbochargers use a Marmon style outlet, which relies on accurately matched flared surfaces to create the seal. When the mating fl**ge is welded to the downpipe, heat distortion can prevent the surfaces from seating correctly, resulting in an exhaust leak.

To provide a more reliable solution, we setup and machine the back of the turbine housing to accept a standard V-band fl**ge with a locating spigot. This positively locates the downpipe, eliminates the original leak path and provides a much more consistent sealing surface.

In for repair is this BorgWarner B03G turbo, fitted to a Mercedes-AMG A45.

The turbo had developed excessive end float, causing the compressor wheel to damage the compressor cover. Rather than throwing the cover away, we machined out the damaged area and built it back up with aluminium weld.

Next, it will go back into the lathe so we can re machine the profile and restore the correct compressor wheel clearances.

A bit of specialised repair work to save a component that might otherwise have been binned

Check out what we found inside this Komatsu turbo that came in with lack of power funnily enough

This JCB came to us with boost-related fault codes. Once we stripped the turbo, we found severe corrosion inside the turbine housing.

This is usually caused by moisture from condensation during long periods of inactivity or short running, or water entering through the exhaust. Less commonly, coolant entering the exhaust can also be responsible.

The corrosion can restrict or seize the turbo’s variable vanes, preventing it from controlling boost correctly and causing underboost or overboost codes.

The fault code tells you where to look the strip-down shows what’s really going on!

A couple of Nissan VG30 turbochargers in the workshop for a freshen up and performance upgrade.

These factory turbochargers feature ceramic turbine wheels, similar to the RB series turbos. For their time, they were an advanced design, combining lightweight ceramic turbines with a ball-bearing centre section to deliver excellent response.

Unfortunately, the ceramic turbine wheels are also well known for failing, particularly on modified engines or after years of service.

For many years we've been upgrading these units by machining a Garrett CHRA into the original housings. This retains around 95% bolt-in compatibility while significantly improving durability and reliability.

Only a couple of minor modifications to the oil feed system are required due to converting them back over to journal bearing

It only needed new seal. If only it was that easy 🤔

Not always.

This bearing housing has a bearing bore that runs true, but the piston ring bore is 0.06 mm out of alignment with the bearing bore.

Because the shaft runs in the bearing bore, the piston ring bore must be concentric with it. Simply replacing the seal ring without measuring won't correct the problem.

The correct repair is either replace the bearing housing with a new one, or grind the ring area seal oversize which will true this to the bearing bore.

Anyone can replace parts. A proper rebuild starts with measurement.
