2. Fasten a 3/8 in. diameter rod 3 in. (76.2 mm) long to the torque converter input shaft with a 1J9778 Hose Clamp. Install a 7H1948 Snug onto the rod. Assemble a 7H1942 Indicator (with a 7H1940 Universal Attachment), and 7H1945 Holding Rod into the 7H1948 Snug.3. Put the universal attachment on the outside diameter of the engine output flange. Rotate the indicator until it stops on "0". Turn the torque converter input shaft 360°. Record the indicator measurement at each 90° of rotation.4. The total indicator reading through 360° of rotation must not be more than .080 in. (2.03 mm). To make the alignment correct, loosen the engine rear bolts and move the engine from side to side. If the alignment up and down is not correct, install or remove shims under the engine rear supports. 5. Remove the universal attachment. Put the face of the 7H1942 Indicator rod against the engine flange between the bolt holes and outside diameter of the flange. Turn the indicator to "0".6. Turn the torque converter input shaft 360°. Make a record of the indicator measurement at each 90° of rotation. The total indicator reading through 360° of rotation must not be more than .026 in. (0.66 mm). To make the alignment correct, loosen the engine front support bolts and move the front of the engine side to side.7. Check the vertical and horizontal alignment again. When the alignment is correct, tighten the engine mount bolts: Front support bolts ... 400 40 lb.ft.(540 55 N m)Rear support bolts ... 400 40 lb.ft.(540 55 N m) If the alignment is off by a large amount, inspect for the cause. If the frame is bent, it can be straightened. If the engine front support is badly worn, a replacement is needed.Torque for the bolts that hold the engine rear support brackets to the side of the main frame ... 225 25 lb.ft.(300 35 N m)
