VERIFY RATIO BEFOREASSEMBLY STEP 1 . Remove the gears to be replaced and thoroughly clean both the gear carrier and housing with solvent to remove any gear/bearing residue, which could lead to abrasive failure of the new gear set. After cleaning, dry- wipe (or air-dry) all disassembled parts, housings, and covers. STEP 2. Examine the ring gear mounting surface for nicks or burrs which might prevent total landing 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 similar surface imperfections, dressing these with block backed pieces of grit paper or a small file. Following material removal (from ANY part of the assembly), bathe the pieces in the solvent and wipe or air-dry. NOTE: Spacers not normally recommended STEP 3. Study the illustrations provided with these instructions. Familiarize yourself with the terms “backlash”and “pinion depth” (sometimes called checking distance). Each set of gears is a matched pair which has been prerun on a gear test machine. Consequently, the pair should never be mixed with other rings or pinions, Also, since all gear sets have been run-checked, specific settings are supplied with each ring/pinion pair. These specifications vary from set to set. Backlash settings are marked on the outside diameter face of the ring gear as follows (see illustration A): Ref: BL.008, which means a backlash figure of .008 inch at the closest point. Pinion depth settings (or checking distance) are marked on the face of the pinion gear as follows (see illustration B): Ref: CD 2.799, which means distance of 2.799 inches from centerline of the ring gear to pinion face. Dimensional variations for backlash SHOULD NOT EXCEED .004″variation. Example: If backlash is .008, the backlash — including maximum variation — should be .008-.012. 1 Illustration B Location of checking distance (pinion depth) & serial no. on pinion Location of backlash dimension & gear serial no. on ring gear Illustration A STEP 4. When installing the pinion gear you must check its depth in the housing as per the pinion depth dimension. Add or subtract pinion depth shims to arrive at the checking distance etched on the surface of the pinion face. (See illustration C.). Refer to Helpful Hints & Additions to Richmond Gear Installation Instructions on pages 3 and 4. STEP 5. Using a mew crush collar or preload shim pack, set the pinion rotating torque to 10-15 (used bearings) 20-25 (new bearings) inch pounds. For oval track applications when not using a cooling pump, set at 16- 17 inch pounds on new bearings and 10 inch pounds maximum on used bearings. STEP 6. After correct installation of the pinion gear, position the ring gear and check for backlash. Mount a magnetic-base dial indicator on the axle housing in such a way that the indicator plunger will be moving in a line that is tangent to rotation of the ring gear. This will provide you with a backlash reading which should conform to the figure etched on the side of the ring gear. Again, maintain a tolerance of .004 variation. Example: If backlash is .008, the backlash – including maximum variation – should be .008-.012. (Backlash is always measured in 3 or more places equally spaced around in the ring gear.) Note: For oval track racing set BL at approximately .012-.014 inches. STEP 7. Compensation for variations in this setting can be made by side-adjustment of the ring gear. Adjusting rings or side-shim packs can be changed to bring the backlash and rotating torque figures into tolerance. (Use same torque on gear bearings as on pinion bearings.) You are now ready to check the tooth contact pattern to assure that no accidental departures from the factory- marked specifications have been made. Apply a thin coat of RICHMOND GEAR compound (“Part # 55-0001- 1″) on gear teeth for best results. Tooth contact patterns should comply with those shown on next page. (Note rounded or bullet nose shape at heel end of pattern on Gear drive sides). See page 4 for patterns and additional installation hints

46RE AUTOMATIC TRANSMISSION DIAGNOSIS AND TESTING – ROAD TESTING Before road testing, be sure the fluid level and control cable adjustments have been checked and adjusted if necessary. Verify that diagnostic trouble codes have been resolved.Observe engine performance during the road test. A poorly tuned engine will not allow accurate analysis of transmission operation. Operate the transmission in all gear ranges. Check for shift variations and engine flare, which indicates slippage. Note if shifts are harsh, spongy, delayed, early, or if part throttle downshifts are sensitive. Slippage indicated by engine flare, usually means clutch , band or overrunning clutch problems. If the condition is advanced, an overhaul will be necessary to restore normal operation. A slipping clutch or band can often be determined by comparing which internal units are applied in the various gear ranges. The Clutch and Band Application chart provides a basis for analyzing road test results. Note that the rear clutch is applied in all forward ranges (D, 2, 1). The transmission overrunning clutch is applied in first gear (D, 2 and 1 ranges) only. The rear band is applied in 1 and R range only. Note that the overdrive clutch is applied only in fourth gear and the overdrive direct clutch and overrunning clutch are applied in all ranges except fourth gear. For example: If slippage occurs in first gear in D and 2 range but not in 1 range, the transmission overrunning clutch is faulty. Similarly, if slippage occurs in any two forward gears, the rear clutch is slipping. Applying the same method of analysis, note that the front and rear clutches are applied simultaneously only in D range third and fourth gear . If the transmission slips in third gear, either the front clutch or the rear clutch is slipping. If the transmission slips in fourth gear but not in third gear, the overdrive clutch is slipping. By selecting another gear, which does not use these clutches, the slipping unit can be determined. For example, if the transmission also slips in Reverse, the front clutch is slipping. If the transmission does not slip in Reverse, the rear clutch is slipping. If slippage occurs during the 3-4 shift or only in fourth gear , the overdrive clutch is slipping. Similarly, if the direct clutch were to fail, the transmission would lose both reverse gear and overrun braking in 2 position (manual second gear). If the transmission will not shift to fourth gear , the control switch, overdrive solenoid or related wiring may also be the problem cause.
