How is the pinion depth of a ring adjusted?
How is the pinion depth of a ring adjusted?
1. Pinion Depth ± The distance from the face of the pinion gear to the centerline of the ring gear. This is adjusted by adding or subtracting shims to the inner pinion bearing. 2. Pinion Bearing Preload -The preloa d applied to the pinion bearings when the pinion nut is tightened. This is adjusted by shims and/or a crush sleeve. 3.
How to install a new ring and pinion?
1. Clean the new ring and pinion gear set to remove any protective coating and /or packing material. 2. After cleaning, dry all parts with an air supply , making sure to not spin the bearings with compressed air (USE EYE PROTECTION). 3. Inspect the tooth areas of both gears for any small chips that may have occurred during shipping.
What’s the proper ring and pinion gear pattern?
Ring and Pinion Gear Pattern is one of the most valuable tools for determining if a differential is properly set up. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns.
How does the pinion gear depth affect the bearing?
The pinion gear depth refers to the distance the pinion gear extends into the carrier. Pinion depth affects where the pinion gear teeth meshes with the ring gear teeth. Pinion gear depth is commonly adjusted by varying shim thickness on the pinion gear and bearing assembly.
Can you set up ring and pinion gears?
Sure, setting up ring and pinion gears can seem challenging, but it really is simple enough that anyone can do it—If they’re willing to pay attention to proper procedures.
When to adjust backlash for ring and pinion?
If the backlash is too wide, adjust the carrier toward the pinion. When adjusting the backlash, a rule of thumb is 10 thousandths of carrier shim adjustment will result in around 7 thou of backlash adjustment. Rock the carrier back and forth until little to no free play is evident.
How is the pinion depth of a ring adjustable?
Pinion depth is adjustable by adding or subtracting shim thickness. Stay +/-.002 of the pinion dimension, (see Figure ‘A’ and ‘B’). 11. Once pinion depth is achieved using a new crush collar or preload shim pack set pinion bearing preload to 15 inch-pounds rotating torque with used bearings, and 25 inch pounds with new bearings.
How to tell the difference between ring and pinion?
This can be checked by dividing ring gear tooth count by the pinion tooth count. e.g. (Ring gear tooth count 35 T, pinion gear Tooth count 10 T, 35 divided by 10 = 3.50:1. 3. Many differential cases have many thousands of miles of service.
