Differential shims for many classic Volvo
04.10.2024
There are many parts in a car that are so inconspicuous that hardly anyone notices their existence. Usually only when they are needed. As in this case, they don't even have to be broken:
When overhauling a rear axle, a lot has to be adjusted. From bearing preloads and tooth flank play to the contact pattern or wheel bearing play, this is done on the Dana-Spicer axles of the classic Volvo using shims. These shims are available in three to four different thicknesses depending on the size, the thinnest is usually around 0.08 mm thick. This enables precise adjustment, which is the most time-consuming part of such an overhaul.
High precision during an axle overhaul is decisive for noise development and service life. If, for example, the input shaft with the bevel gear had play instead of the required preload, this would lead to massive damage in a very short time, and it would also be impossible to adjust the tooth flank clearance.
We have had these adjusting washers in our product range for some time now, both individually and as a set. Unfortunately, it happens from time to time that individual sizes are no longer available from the vehicle manufacturer or its suppliers. We now produce these ourselves, such as the sizes listed below for the outer differential bearings.
The washers are located under the outer bearing of the differential and are used to adjust the tooth flank clearance and the contact pattern. They also provide the preload with which the differential is firmly “clamped” by the axle. In the cover picture, you can see the adjustable placeholders on the right-hand side, which can be used to determine the thickness of the necessary shims.
We know only too well from our own experience that a howling rear axle can thoroughly spoil the fun of the Amazon, P1800 or Hump.
That's why the adjustment shims are now available in our store under the numbers listed below for the greatest possible precision when making adjustments.
