Next, we re-inspect the front 4-pinion planetary assembles – measuring clearances and making sure everything is within our own rigid specifications before installing it and inserting the output shaft. No matter how hard you beat on it, THIS SHELL DOES NOT BREAK! The GFX Shell is able to withstand the rigors of the street, the strip, or the mud whichever is your pleasure. We then replace the sun shell with a new heavy duty unit The GFX Shell, which far exceeds the factory component. Simply put, these planetary assemblies with good lube DO NOT EASILY FAIL even in the most demanding environments. When you see one of these with a damaged rear planetary, it will almost always be accompanied by the blue-black signs of excessive heat. Their failure is almost exclusively due to a lack of lubrication. In fact, contrary to common opinion, the rear planetary assembly in these transmissions is not, in any way, weak by design. This is a huge improvement and virtually eliminates one of the most common points of failure for this type of transmission.

This allows oil to escape from between the bearing and the gear it rests against, feeding additional lube to the planetary gears. Next, the sun gear is inspected and modified to improve lubrication to the rear 4-pinion planetary assembly. In addition, dual bushings are installed in the rear sun gear to handle the extra weight of the beast sun shell. At this time the center support and sprag (one way roller) are installed after being inspected for stress cracks and damage. The rear 4-pinion planetary assembly and bearings are meticulously inspected, then assembled into the case along with heavy duty reverse friction and steel plates. The seals in the case are then replaced and assembly begins. The case is specially prepared and a coating of and heavy duty, heat resistant, oil based enamel is baked on, creating a hard and durable glossy finish. The case and hard parts are cleaned thoroughly and re-inspected for cracks, wear, or other damage before we begin.
