This high-performance gear set is made in the U.S.A. and undergoes a unique treatment known as Isotropic Superfinishing (ISF ). The ISF Process produces not only an outstanding highly-polished look, it also generates a non-directional low Ra surface (the measurement of surface finish, or smoothness, of a part). Produced with mass finishing equipment in conjunction with chemical accelerants, the ISF Process is non-hazardous and environmentally friendly. 3

Strange Engineering primarily manufactures its own products, but is very selective when choosing to partner with other companies that enhance its products and brand. We have had a long lasting relationship with US Gear and I can unequivocally state that the people at US Gear get it. They are not manufacturing the least expensive gear set to get the sale. They are manufacturing a quality US made gear set that is strong, efficient and quiet not easy to do. More importantly, US Gear is extremely dedicated to continuously improving and investing in making its product better. I believe what really separates a performance company from the rest of the field is a constant obsession with being proud of what you produce today knowing that tomorrow you will evolve and make it better.

Coast side of Gear Face Milling Face Hobbing Condition Face Milling Face Hobbing Action Required A Optimal Contact Pattern is concentrated in the center of the drive gear tooth. No action required. B High Contact Pattern is concentrated at the crown of the crown of the drive gear tooth. Move the pinion deeper in towards the differential carrier (add pinion shim). C Low Contact Pattern is concentrated in the root of the drive gear tooth. Move the pinion out, away from the differential carrier (subtract pinion shim). Heel Contact Pattern is concentrated off the heel end of the drive gear tooth. Move the ring gear closer to the pinion (decrease backlash) while maintaining minimum backlash. Toe Contact Pattern is concentrated off the toe end of the drive gear tooth. Move the ring gear away from the pinion (increase backlash) while maintaining minimum backlash. 22

23 Installation Instructions U.S. Gear Street & Competition Ring & Pinion Sets 1. Remove the old gear set and thoroughly clean both the ring gear carrier and rear end housing with solvent. After cleaning, air-dry all parts. 2. Examine the ring gear mounting surface for nicks or burrs which might prevent a flush mounting of the newly installed ring gear. Ring/Pinion tooth depth variations can result from a ring gear that is cocked on its mounting surface. If a ring gear spacer is to be used, also check it for surface imperfections. Nicks or burrs can be removed by using block-backed grit paper or a small file. Following material removal, rewash in solvent and air dry. Mount ring gear. Loctite ring gear bolts and torque to factory specifications. 3. All U.S. Gear gears have been lapped in sets and should never be mixed with another ring gear or pinion. Check to see serial numbers are the same on the ring gear and pinion. 4. Each U.S. Gear gear set is pre-run and marked on the pinion face with its proper depth setting called the Checking Distance. This dimension is from the face of the pinion to the axle centerline. A setting tool must be used to measure the checking distance. Pinion depth is adjusted by adding or subtracting shim thickness. Stay +/-.002 of the pinion dimension. 5. Once the pinion depth is achieved, install a new crush collar (preload shim pack for Dana s) and seal. Then loctite the pinion nut and tighten to 15 inch-pounds rotating torque with used bearings or 25 inch-pounds with new bearings (we recommend use of new bearings on new builds). 6. With the pinion gear installed, position ring gear and carrier into housing to check backlash. Our are developed to be run at.008" to.012" backlash for street gear sets and.006" to.008" backlash for competition gear sets. 7. Adjustments for backlash are done by spanner rings in the housing or shim packs behind the carrier bearing cups (GM) or cones (Dana). Always be sure carrier bearings are pre-loaded. The carrier should not fall out of the housing, but should have to be tapped in during final installation. Replace bearing caps and torque to factory specifications. 8. You are now ready to verify the tooth contact pattern. A gear marking compound should be used. Paint gear teeth with compound in several spots and rotate ring gear several revolutions. A tooth contact pattern will appear and should be similar to the pattern shown in Illustration A. If the pattern is not in the approximate position shown, reset pinion depth and backlash to correct pattern. Pinion shims usually must be moved in.003 of an inch increments to notice a pattern change. If a pattern is heavy toe subtract shims, (See Illustration C). If a pattern is heavy heel add shims, (See Illustration B). NOTE: Reverse this procedure for 8" and 9" Ford. 9. Fill the case with the required amount of EP85-90 gear lube, and maintain the proper level at all times. Proper maintenance is a must to protect you and the gear set. Break In Procedure A new ring and pinion installed with new bearing following will initially generate higher than normal operating temperatures. It is advisable to use whichever of the break in procedures matches your application. STREET APPLICATIONS: 1) With car still on jack stands and rear-end filled with proper amount of lube, run in forward and reverse approximately 2 to 3 minutes. *** 2) Drive vehicle approximately 10 miles at normal operating speeds. Accelerate and decelerate several times conservatively, then let cool for one hour. COMPETITION APPLICATIONS: 1) Repeat step one above. *** 2) Run several laps at slow to medium speeds; let cool. 3) Run several hot laps; let cool. FOR DRAG RACING 1) Repeat step one above. *** 2) Pull to line.
