BRACKET 2800454 - Caterpillar

1. Remove the bolts, joints and torque converter flange.2. Fasten a 3/8 in. (9.5 mm) 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). The alignment can be made correct by loosening the engine rear bolts and moving 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. If the holes for the support bolts have become larger because of wear, dowels should be installed after the engine has been fastened down. [See Step (8)].6. 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".7. Turn the torque converter input shaft 360°. Record 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). The alignment can be made correct by loosening the engine front support bolts and moving the front of the engine side to side.8. Check the vertical and horizontal alignment again. When the alignment is correct, tighten the engine mount bolts:Make reference to ENGINE MOUNTING BOLTS for the correct torque for the bolts that hold the engine to the frame. 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.
