Set the ring and pinion shaft - is one of those jobs that even the most experienced 4x4 builders are coming up with questions. Probably no other work done in a 4x4 that has more mystical setting gears. Why work has the reputation it has? Is it worth it? Can even the first timer get decent results at home? The answers, in order, are: "You will understand by the end of this article", "class" and "Yes, yes you can."There are four main reasons that the work is on that very short list of tasks most of us like to avoid: Toolbox. There are a number of specialized tools necessary to do the job, most of which are not commonly found in the store at home. The good news is that some of them can be avoided by not having and the others are interesting tools you should have and have been meaning to get anyway! Weather. There are several interrelated adjustments to be made, each one affects the other, so that time and patience are needed as a "juggle" the adjustments to arrive at the best solution. Can not one thing in isolation and move to the next - as you change backlash, so that changes the pinion depth, adjust the depth of the pinion bearing preload and alter and so on. However, taking the time to do it right yourself is very rewarding. Precision. "Close" is definitely not good enough at tuning gear. There are exacting specifications and tolerances of minutes to meet - and with good reason. The ring and pinion gears are where all the power of 
your motor is energized 90 ° - from the longitudinal axis of the crank-shaft to the lateral axis of the axle shafts. If you do, put tremendous pressure on the differential carrier gear teeth. In order to resist theseen destroying other nearby parts.There is plenty of material in this paper - background for specific instructions step by step with photos attached. At first glance it may seem a little intimidating in itself. Actually it is not, but to help keep things clear in your mind - I'll start with this graph that describes the basic steps for creating cogs. Keep it handy and refer to it often as you read well and soon to be an expert in arts.Quick Steps Ref:- Assemble all tools and parts in clean work space - Remove, clean and inspect all parts - Make settings bearings, if necessary - Measure and label new wedges - Calculate shim stacks from - Install the ring gear shims and bearings from configuration - September backlash - Set the depth of the pinion and pinion bearing preload - Check the contact pattern and adjust as needed - Backlash Re-check and contact pattern - September carrier preload - Installation of new races and bearings - Final check of the game, the contact that both the ring and pinion are shaped cut the bottom cone. Spiral teeth of the ring and pinion have different spiral angles - creating a rolling or sliding contact, as they fit. This sliding contact begins gradually at one end of the tooth and proceeds smoothly to the other end. The contact also overlap, which means contact the next tooth contact begins before the previous tooth over. This overlapping, sliding contact reduces noise and vibration and prevents load dangerously concentrated near each end of the tooth. In order to achieve this sliding / overlapping contact without jamming, the curvature of the ring gear teeth must be different from the curvature of the pinion gear teeth. One can see in Figure 5 that the pedal sprocket teeth curve more than the teeth of the ring gear. Due to this asymmetrical curvature, in order to achieve an equal amount of drive in both directions (imagine how strange it would be if you were more forward than backward through the same number of revolutions of the drive shaft) of each of the teeth, both on the ring and pinion have uneven pressure angles. You can see an example of this by looking at the base (or root) of the ring gear teeth in Figure 5 - Announcement of how an angle of almost 90 ° and the other near 45 °. The result is that the ring gear teeth have a concave side and a side slightly convex. What does all this fancy engineering, is that in order to get the gears are smooth, strong, and quiet you need to set them up with great precision. Eg Mounts must be sufficiently rigid to minimize deflection of the gears under load, so that no tooth localized pressure rises too high and cause tooth breakage. This means axle housings must be true and square, carrying plugs must match, and carriers must be strong. The gears should be kept in proper alignment by a wide range of operating speeds and loads. This requires roller bearings in good condition and with good pre-load. Contact prong (mesh) should be carefully controlled so that the contact stress of the tooth out and not localized, otherwise damage to the teeth surface, broken teeth, and the result noisy operation. This means using only matched ring and pinion sets and accurately set backlash and pinion depth. Suitable lubricant to be used to withstand the high shear forces encountered between teeth lubricants as mesh. This means that the use of nominal hypoid gear oil suitable and establishing sufficient slack in the gears mounted to allow space for a sufficient lubricating film on the gear teeth. If the teeth fit closely (sufficient clearance), the oil can be squeezed between the teeth or trapped in the roots of the teeth that cause excessive heat and load the tooth.In short - there's a darn good reason creative work has the reputation gear is made and that professionals are paid good money to do well, but with a little patience and the right knowledge you can do a good job yourself.Note: There are many different types and styles automotive axle gear. Some have a removable central sections (Toyota, Ford 9 inches), some rings used for adjusting the preload bearing support (14 pin) and some supplements use (Dana), some folding separator used to adjust preload pinion support (Dana 35), some use solid wedges (Dana 70) and still others use one or the other, depending on the specific model (Dana 60). As such, it is possible that I cover every single detailed procedure for each type of shaft. The procedures and photos of this article developed during configuration of the gears in the Dana 60 front axle. However, the theory, naming conventions, and the order of basic steps and detailed procedures, such as reading the contact pattern of the teeth, apply to any axis
