4. INSPECT SPRING FREE LENGTH Measure the free length of the spring. Limit: 31.3 mm (1.232 in.) SELECT ADJUSTING SHIM 1. MEASURE RH CASE Measure the RH case as shown in the figure. "A" = Case dimension. 2. MEASURE SIDE GEAR, THRUST WASHER AND CLUTCH PLATE (a) Assemble the side gear, thrust washers and clutch plates on the side gear. HINT: Do not assemble the adjusting shims. (b) Using SST to press down the thrust washers and clutch plates with about 10 kg (22 lb) of pressure, measure dimension "B". SST 09726-35010 Total shim thickness C: "C" = "A" - "B" - 16.15 mm (0.6358 in.) (c) Referring to the section table on the next page select the proper adjusting shims. HINT: The thrust washer attached to the outside of the side gear is marked from A to M according to thickness. This part is used only during assembly at the factory and therefore is neither a supply part, nor does it have a part number. During repair, install the selected adjusting shim (marked A through E) between the outermost thrust washer and case.
