Stationary Gear Grooving
In 1993, upon Mazda's release of the third generation RX7, there were several changes made to the quality and strength of the 13B engine. One of the modifications released at this time was the use of a multi-orifice main bearing in conjunction with a grooved stationary gear. The function of the groove with in the gear is to channel oil all the way around the underside of the bearing. When under pressure, the oil will flow evenly through the multi-orifice bearing. Pre ‘93 engines were equipped with standard gears and one central oiling orifice. REC can transform your existing gears to accept a special "3 window bearing." And thus with in this modification, we will machine the groove into your stationary gear to allow for proper operation.
