Fig. 24: Measuring Output Shaft Bearing Preload
Courtesy of FORD MOTOR CO. 3. Unthread gauge tool until output shaft bearings are seated and no play exists. Install Torque Adapter (T87C77000-E) over splined end of output shaft. Using INCH lb. torque wrench, rotate output shaft while unthreading gauge tool. Unthread gauge tool until 4.42-7.97 4. Using feeler gauge, measure gap of gauge tool. Select correct thrust shim(s) that match measured gauge tool gap. Shims are available from in thicknesses of .004" (.10 mm) to .007" (.18 mm) in .02 mm increments. One shim is available in thickness of .019" (.50 mm). 5. Disassemble output bearing and idler support from converter housing. Remove gauge set and spacers. Install selected shim(s) in output bearing and idler support. DO NOT exceed 7 shims. Remove bearing race from gauge tool and install race in support. Reassemble TORQUE SPECIFICATIONS . 6. Install Torque Adapter (T87C77000-E) over splined end of output shaft. Using INCH lb. torque wrench, rotate output shaft to confirm correct bearing preload. Turning torque should be .26-7.96 INCH lbs. (.03-.9 N.m). If turning torque is not within specification, repeat 7. Once correct output shaft bearing preload is obtained, remove output bearing and idler gear support. Replace idler gear shaft seal on idler gear shaft. Install idler gear into converter housing. Install output gear and bearing support. Ensure alignment groove in idler gear 8. Install new idler gear shaft roll pin. Install output gear and bearing support bolts and tighten bolts to specification. See TORQUE SPECIFICATIONS . DIFFERENTIAL BEARING PRELOAD ADJUSTMENT 1. Install differential assembly into converter housing. Position differential side bearing race in recessed end of Gauge Tool (T87C- 770002DJ). Place gauge tool on differential. See Fig. 25 . 2. Ensure gauge tool is completely threaded together so that no gap is present. Position spacer collars and assemble case halves using supplied bolts and washers of tool set. See Fig. 25 . Tighten bolts to 22-34 ft. lbs. (292D46 N.m). |
