Picture of broken gearbox Picture of repaired gearbox casing

We received the above gearbox which was damaged in an accident. TIG welding was used to repair the aluminium bell housing. We re-aligned the mating surfaces and machined to factory specs.


Damaged Ferrari gearbox before repair Welding repair to Ferrari aluminium gearbox

The above gearbox came out of a Ferrari that was damaged by loose internal components. We repaired the damaged internal oil passages, structural damage, and made new side shaft bearing housings, which are not shown above. TIG welding was used to repair the aluminium components.

We carried out the simple welding repair above to repair damage caused by road debris. Aesthetics were not important to the owner in order to keep costs down.


Cracked aluminium gearbox before repair Welding repair to cracked aluminium gearbox

A disintegrating flywheel caused the above damage. You can see the multiple gouges in the bell housing's surface. We repaired the above damage with aluminium TIG welding.


Broken mounting on aluminium truck gearbox Welding repair to aluminium truck gearbox

Excessive vibrations caused by a sand road damaged the Mercedes truck gearbox above. We did not use the broken piece in the repair process. Instead, we built up the entire broken mounting with aluminium TIG welding, and then machined back to specifications.


Cracked aluminium gearbox Welding repair to cracked gearbox

Accident damage caused the cracks in the above aluminium gearbox. We repaired with the usual TIG welding process, and the result was a usable gearbox.


Galled aluminium gearbox thrust bearing guide Galled aluminium gearbox thrust bearing guide repaired

We repaired the above damaged thrust bearing guide using unconventional methods. Machining the worn guide down to accept an aluminium sleeve was the first step. The sleeve was custom turned for this application, resulting in another usable gearbox.

As with the example before this, we repaired the above damaged thrust bearing guide using the same unconventional methods. Machining the worn guide down to accept an aluminium sleeve was the first step. The sleeve was custom turned for this application, resulting in another usable gearbox.


Audi gearbox mounting lugs ripped off in accident Welding repair to  Audi gearbox mounting lugs

An accident damaged the above Audi gearbox, resulting in the mounting lugs being broken off. We built up the broken lugs with aluminium TIG welding, and hand machined back to the original shape. We welded the holes back into the lugs when repair welding.
