WASHER 7H3951 - Caterpillar

(1) Remove the muffler, precleaner and hood. Remove enough coolant from the radiator to permit removal of the radiator upper hose and the heat indicator tube. (2) Install bolts in holes (1) to hold plate (2) in position on the radiator guard. Make a .10" (2.5) square groove weld followed by a .19" (4.8) fillet weld all around plate edges (A). Remove the bolts from the plates. (3) Use the bolts to put bracket (3) in position on plates (2). Install tube (4) on brackets (3). Use a .10" (2.5) square groove weld followed by a .25" (6.3) fillet weld around the bracket edges to fasten the brackets to the plates. Remove tube (4). Put a .10" (2.5) square groove weld followed by a .19" (4.8) fillet weld on the inner side of the bracket. Remove the bolts from the brackets. Install tube (4). (4) Fill the ends of tube (4) with grease. Put a seal on each yoke (5) and install the yokes in the tube. Install pins (6) in the tube to hold the yokes in place. Install gasket and covers to hold the pins in place. On the right side only, install brackets (7) over the cover. Install the grease fittings. (5) Put pins (8) in the position shown and make a .19" (4.8) bevel groove weld followed by a .31" (7.8) fillet weld to fasten the pins to the radiator guard. (6) Install tubes (9) and (10) on manifold (11). Install the manifold on tube (4). Use clips (12) to hold the tubes on brackets (7). Using flanges and seals, connect tubes (9) and (10) to hoses (13). (7) Remove tube assemblies (14) from the lift cylinders. Install caps (15) and install the cylinders to the yokes. Install tube assemblies (14). Fasten the cylinders to pins (8) with links (16) as shown. Install the grease fittings. (8) Install four hoses (17) as shown using seals, flanges, lockwashers and bolts.Assembly Of Blade
Remove all paint and dirt from the bearing surfaces. Install push arms (1) with retainers (2), caps (3), bolts (4) and 8J9180 Shims as necessary at location (A) to permit free movement of the push arms. (See bolt tightening procedure, last page.) If the machine is equipped with a tilt cylinder, install brace (5) on the left push arm only with 8J9180 Shims as necessary at location (B) to permit free movement of the brace. Tighten brace (5) mounting bolts to a torque of 640 80 lb. ft. (870 109 N m). (2) Install the bearing in strut (6); install retainer (7), bolts and washers. Push the end of strut (8) through the bearing into strut (6). Connect struts (6) and (8) to the push arms with pins (9) and cotter pins. Install link (10), screws (11) and braces (12). Keep both dimensions (A) the same during any adjustment. Adjust braces (12) until the distance between the center of the push arm trunnion bearings is 116.24" (2952.5).Blade Tilt Cylinder
