Factory Rotor Re-Balancing
Although Mazda factory rotating assemblies are balanced fairly accurately when produced,REC has perfected methods to increase accuracy and performance. One area of the rotating assembly which we have learned can be improved is the rotor itself. The rotor rebalancing is a procedure performed on just the rotor using a series of corrections and adjustments by removing material from certain areas of the rotor. This procedure is referred to as balancing the rotor on its own axis. With a specially designed custom arbour, and the use of our high end machine, we can determine where material needs to be removed accurate to half a gram.
The rotors which become candidates for rebalancing would be units which have been machined or altered in any way, rotors which has been lightened, clearanced or had 3 mm slots milled into the apex's, are all good examples for units which should be rebalanced. When mixed and matched parts from different years and models are used it is always a good idea to perform this procedure. We recommend re-balancing factory, already balanced, rotors when building a performance or high-end engine which will be used for racing.
Re-balancing unmodified factory rotors, clearance rotors or rotors which have had apex modifications is one of the more straightforward applications for re-balancing the rotor on its own axis. In these circumstances we see limited or very little corrections to be made. Notwithstanding, this is still a very relevant and important procedure to complete. Rebalancing rotors which have undergone extensive modifications such as removing material to make the rotors the same weight or lightening rotor such as the CNC lightening which we offer, require more extensive work to accurately be re-balanced.
It is also recommended that once the rotors are balanced on their own axis, that the counterweight corrections and balancing of the entire rotating assembly becomes absolutely necessary.
