Similar to the engine block or cylinder head, there is damage in the area of gearbox repair that makes it impossible to use the classic car. Broken out areas, damaged bearing seats or sealing surfaces are just a few of countless examples.
How can we help?
With decades of experience and craftsmanship in laser precision welding, we can get just about any damage repaired. The advantages: Despite very fine, filigree seams, we guarantee you a durable and resilient gear repair through the right choice of filler metal and extremely precisely adjusted welding parameters – without any heat distortion at all.
Furthermore, we are specialists in welding cast iron, aluminium and aluminium-magnesium alloys. Thanks to a specially developed method, we are also able to carry out this special gearbox repair absolutely permanently and without cracks.
Crack in gearbox housing
Particularly in a certain model of vintage Porsche, a crack often occurs in the gearbox housing.
The challenge: welding the aluminium-magnesium alloy that is present here.
In our classic car workshop, we have developed our own process in laser welding technology that allows us to address precisely these controversial conditions in magnesium welding.
For 20 years now, we have been pleased to use this method to achieve 100% bonding and flawless X-ray samples.
We were able to successfully save more than 70 Porsche gearboxes (and also several cylinders) with this procedure.
Crack and hole in the gearbox housing
We localised the crack and hole under the microscope, ground them out and then rebuilt them. The use of lasers for aluminium welding virtually eliminates heat distortion during the gearbox repair. Bearings, gearbox output shafts and all linkages fit exactly in their position again.

Broken out bracket
The vintage motorbike had a crack in the gearbox cover and a broken-off bracket.
The crack is resealed by laser and the broken bracket can also be welded on again.
By the way: Broken parts in the carburettor of vintage motorbikes are also part of our repair services.
