Let’s talk some more about Quality……
So what are the Gears in a Holinger Gearbox made from? Whilst we don’t give it a fancy name we made up, the steel we use is made specifically for us, to our spec, in Germany. We have to order it sometimes 1 year in advance. You can see some that we have stored in the factory currently. Why do we do this? Cleanliness is part of the answer. In our modern world we’re finding it harder and harder to get things made or supplied to the level we used to take for granted. Raw materials are a great example of that……
How then do we know what we’re getting? We check it ourselves of course. Each bar is coded and a sample cut from it. We then prepare this sample and check it microscopically, which allows us to judge its cleanliness. If it’s considered “dirty”, then we reject it. We’ve been doing this for well over a decade.
We also keep track of which bar our Gears were made from, so even if we see an old gear from 10 years ago, we’re able to track it back to the material sample we still have on site.
So we know what we’re making our products from: The steel that is commercially available these days is often far dirtier than we’d expect and therefore making highly stressed motor racing components from it, comes with enormous risk. We don’t do that, so you know the parts you buy from us are made to the same standard each time. This enables proper, repeatable, service-life expectations.
Isn’t this critical in Motor-Racing? We believe it is, so continually make this huge investment in quality from the start. Our raw material price is much higher than elsewhere (double or more), we have to order it, pay for it and store it for perhaps a year or more before we use it.
These days there are many companies making Race-Car Gearboxes. Unfortunately many of our competitors don’t go to the lengths we do, to ensure that even the raw materials they use are up to standard. They source steel from questionable places, which is often “dirty” and full of microscopic inclusions that can cause premature component failure. The big problem here is that if this were consistent, perhaps you could work with it. But when you get 2000KMS from one gear, then 300KM from the replacement one, how do you manage that? Usually this requires a maintenance schedule which is time consuming, resource consuming and therefore costly! If you don’t keep this constant maintenance up the end result could be a sudden, unexpected failure. What happens in a Gearbox when 1 of the 5, 6 or 7 pairs of gears fails? Well they usually take their friends with them. So 1 gear failing prematurely can then equal the cost of 6 premature failures in a single blow.
This is where less expensive gearboxes can become very expensive, very quickly. As it was suggested to us in our last post about quality, Holinger Gearboxes are very cost-effective over their life-time. Yes the purchase price is higher than many other options, BUT, if a gearbox that cost half what ours cost has an unexpected catastrophic failure, can you then afford to fix it? After that can you then afford to fix it again the next time? We often hear from customers “I should have bought one of yours the first time”. This is after they have spent more than the cost of a Holinger Gearbox purchasing an inferior brand, and then had to fix it after it failed multiple times.
There is no such thing as a cheap race car gearbox. Even the cheapest option is not cheap. So think hard about what you’re handing your hard earned money over for. Visually flashy parts made from cheap, inferior materials are not going to make you happy in the long run!
