The wear-prone drive pin and the entire balancer shaft module are eliminated. The oil pump is once again driven directly by the crankshaft — via a robust chain and a larger high-performance oil pump. The long-term solution since 2015.
We all know this scenario only too well, and it brings real frustration: many manufacturers seem to design their products with a built-in weak point. It's an open secret that certain components are engineered so their service life is artificially limited — for exactly as long as suits the manufacturer. Often these specific parts are either expensive or simply unavailable. A strategy aimed at pushing customers toward repeat purchases.
Of course, it is not our intention to jump to conclusions or attribute unjustified motives to manufacturers. Our observations are based on first-hand impressions, backed up by what we consider an unusually high failure rate for these products.
This is especially striking with certain engines, where the suspicion of planned obsolescence is reinforced not only by numerous reports online, but also by our direct customer contact spanning more than a decade. Our experience and the exchanges we've had with our customers have shown us that this is more than just a handful of isolated incidents.
With this conversion, you remove the balancer shaft module problems for good. Continuous oil pressure is restored and significantly improved by a high-performance oil pump.
Let us clarify upfront that the drive pin driving the oil pump, while the biggest problem, is not the only one.
The balancer shaft module is driven by the crankshaft and in turn drives the oil pump. It's well known that oil pressure is critical to engine longevity. Oil pressure that is too low leads to increased wear. Our reinforced drive pin is a good, cost-effective solution, but it doesn't offer absolute certainty.
The problem already starts at the crankshaft, which carries either a sprocket or a spur gear. This drives the balancer shaft module via a chain or an idler gear. The first balancer shaft then drives the second balancer shaft via two further spur gears. The second balancer shaft finally drives the oil pump via a far too small drive pin (hexagonal).
So there is a whole series of components sitting between the crankshaft and the oil pump. Traditionally, oil pumps in a combustion engine are driven directly by the crankshaft. Our conversion system restores exactly this simple, proven principle to your vehicle.
Another advantage is that the far-too-small oil pump is also replaced with a larger one in the process. The original oil pump is positioned so unfavorably on the balancer shaft module that there's no room for a technical upsize. The manufacturer tries to compensate for the low delivery volume of the very small oil pump with a higher rotational speed. Our experience shows that this causes problems. Engines that are typically somewhat worn due to their mileage need more oil than new engines. This can lead to insufficient lubrication in the engine and turbocharger — and a repair then quickly becomes very expensive.
Our reinforced drive pin is a cost-effective solution for one major problem. But if you want to be on the safe side, you're better off replacing the entire balancer shaft module with a directly driven high-performance oil pump through a conversion.
Our products are designed digitally on computer using CAD technology and have to prove themselves in practice over a long period.
Besides the practical tests, it's also the customers who carry out this conversion on their vehicle who contribute valuable long-term experience. We maintain a lively exchange with our customers. Many of them get in touch with us on their own initiative after many years to share their experience.
We feel truly honored by the positive feedback from our customers, and it reinforces our approach. Every single testimonial underscores the effectiveness of our method. The feedback shows that our solution has so far been the most effective way to permanently fix the balancer shaft module problems. No other method can compete in this respect.
Of course, if the balancer shaft module, the oil pump, the spur gear drive, etc. fail, a repair is also possible. But such a repair often leaves behind:
On top of that, a repair is often so expensive that it doesn't make economic sense. The labor time for a repair is also a significant cost factor. We therefore recommend carefully considering whether the cost of that labor wouldn't be better invested in a permanent solution.
