Acceptable wear patterns are shown on the right. Adjusted by moving the ring gear inward or outward fro m the pinion gear by shimming the carrier. Put away those cumbersome gear ratio charts. Challenger GT: On a Challenger GT you will find that there is an active transfer case that sends power to the front axle. A-4209-AR Service Replacement gears were 3.78:1 ratio. 41 teeth on ring gear. Now, turn the pinion yoke through enough revolutions to rotate the ring gear one full turn, applying some drag to the ring gear/carrier by hand. This assumes no other changes such as tire or wheel size, engine changes or transmission changes. Using the original shim measurement for the initial tests are always good - you need a baseline.

Divide the number of teeth on the spur gear (100) by the number of teeth on the pinion gear (15). This calculator is designed to give the potential speed values of a vehicle, based on the RPM of the engine, the ring gear and pinion gear ration, the final transmission gear ration (usually 1.00) and the tire diameter, ground to top of tire as mounted. This is due in part to the deeper bell housing and longer pinion shaft. A simple and 100% accurate way to find a ratio is by physically counting the number of teeth on the ring gear and teeth on the pinion gear. Once the pinion gear is installed, position ring gear and carrier into housing to check backlash. Our experts will help you find the correct ring and pinion set for your particular application.

Rear-End Type. To do this, notice the depth of the ring gear tooth - dimension "A" and "B".

Available In Ratios From 3.89 Thru 6.20. 2-Cut Face Hobbed Ring and Pinion Contact Pattern Summary. Check for worn bearings and replace as necessary. If a ring gear spacer is to be used, also check it for surface imperfections. This is adjusted by shims and/or a crush sleeve. Drivetrain / Ring Gears / Final Drive and Carefully note the contact pattern that shows up on the teeth where the substance used has been wiped off. Thus, a 4.10 ring and pinion will be stronger than a 5.29 ring and pinion. add t to end of part# for all timken bearing kits. As the ratio is numerically increased for a given size ring gear, the pinion must get smaller and is therefore weaker. On a Face Hobbed or 2-Cut Gear as backlash decreases, the pattern shifts toward the Root on both drive and coast sides. Description: US Gear Ring and Pinion # 07-910543HD | Ford 10" PRO Dual Bolt Pattern | 5.43 Ratio MADE IN THE USA!

Save yourself the headache and let us figure out your ring-and-pinion gear ratio! STEP 1: With pinion removed, place differential case (ring gear removed) with differential bearings and differential bearing cups in rear axle housing. Load the ring gear and run a full contact pattern check. This means that with the same size ring gear, a Divide the ring gear teeth number by the number of teeth on the pinion. The ideal pattern is seen in the top two examples on the right. 41 teeth on ring gear. 41 teeth on ring gear. Tire Size 2. Use this gear ratio calculator to see what ring & pinion gear ratio will be right for you after a tire size change. gear ratio = ( * diameter of input gear)/ ( * output gear)gear ratio = (diameter of input gear)/ (diameter of output gear)gear ratio = (radius of input gear)/ (radius of output gear) 1. ring & pinion kit: ring & pinion ring & pinion master kit: ring & pinion and differential master bearing kit. Ring & Pinion Identification. 9310 Alloy Steel. There are two basic types of conditions that will produce ring and pinion noise. Transmission Ratio 3.

Example. You should be able to find your gear ratio listed on the axle tag, however, if that has gone missing, you can simply count the number of teeth on each gear and divide the number of ring gear teeth by the number of pinion gear teeth.

Divide the ring gear teeth number by the number of teeth on the pinion. In some applications, you might choose to go with lower gears than usual. The gear ratios can remain as is for most of the other adaptions. Possible Cause #3: Incorrect backlash can lead to damaged gear teeth. The 091 is also quite a bit longer. Begin by setting proper pinion bearing preload, total turning preload, and ring gear backlash. The following are typical ring gear patterns. 1979-1995 Hilux/4Runner. Improper gear spacing will lead to wear and damage to your gear set. Ring/ Pinion tooth depth variations can result from a ring gear that is cocked on its mounting surface. With the pinion gear and differential in place, rear-end marking compound in place, and with the bearings only snug (just tight enough to eliminate any play), check the pinion depth by way of the contact pattern that can be found by the rotation of the pinion against the ring gear. You can, too.

Richmond Gear is the leading manufacturer of professional quality, high performance ring and pinion sets. Backlash The distance between the mating surfaces of the ring and pinion gears. Ford 9 inch Gears. The second type of ring and pinion noise pertains to the mesh pattern of the gear pattern. For example, a 3.73 gear ratio requires 3.73 driveshaft rotations to turn your tires once around. Ford improved tooth contact of the Ford 9 inch gears by locating its pinion gear lower on the ring gear. For the finest in quality and affordability, USA Standard differentials, axles, driveshafts, and ring and pinion after-market parts are better than OEM Replacement. Two GearsStart with a two-gear train. To be able to determine a gear ratio, you must have at least two gears engaged with each other this is called a Count the number of teeth on the drive gear. One simple way to find the gear ratio between two interlocking gears is to compare the number of teeth (the Count the number of teeth on the driven gear. More items Enter the number of teeth for the following gears. There are slight errors in the overall ratios on the chart with a few of the spur gear sets. Ideally, a gear ratio should be selected that will let the engine rev just slightly over the specific RPM where maximum horsepower is made. Anyway, you need to measure the bearing race diameter first, divide it in half and record this number.
