To find the final driven pinion gear shim thickness “B”, use the following formula. Final driven pinion gear shim thickness h – ( e f + g ) e = a numeral (usually a decimal number) on the final gear case either added to or sub- tracted from “71.6”. f = a numeral (usually a decimal number) on the outside of the final driven pinion gear either added to or subtracted from “51.0”. g = a numeral (usually a decimal number) on the outside of the final driven pinion gear either added to or subtracted from “24.0”. h = 49.8 Example:
1) If “–03” is stamped on the final gear case, e = 71.6 – 0.03 = 71.57 2) If “–12” is stamped on the outside of the final driven pinion gear, f = 51.0 – 0.12 = 50.88 3) If “–05” is stamped on the outside of the final driven pinion gear, g = 24.0 – 0.05 = 23.95 4) h = 49.8 5) Therefore, shim thickness “B” is 5.16 “B” = 49.8 – (71.57 – 50.88 + 23.95) = 5.16 1 2 h e f 7 - 32 REAR CONSTANT VELOCITY JOINTS AND FINAL DRIVE GEAR DRIV DRIV
