Engine Disassembly and Assembly Pistons And Connecting Rods 6. Put 6V3029 Spacer (11) in the base plate. Put the connecting rod on the base plate of tooling (B). 7. Put the connecting rod piston pin bearing end in the center of the port assembly of tooling (B). Install pin (6) in the center of the bore for the connecting rod bearing. 8. Install 6V2049 Adapter (9). Put the hole in the adapter in alignment with the hole in the base plate of tooling (B). 9. Install clamp bar (10) and clamp pin (7). NOTE : The old bearing is pushed out by tooling (B) as the new bearing is installed. 10. Put 5P8645 Pusher Adapter (8) in position as shown with the taper side down. The piston pin bearing joint must be in alignment with the hole in adapter (9) and the base plate of tooling (B). 11. Put pusher (4) on adapter (8). 12. Use tooling (B) to push the new piston pin bearing (5) into the connecting rod until adapter (8) of tooling (B) makes full contact with the connecting rod surface. 13. Remove the connecting rod and the old piston pin bearing from tooling (B). 14. Check the piston pin bearing bore diameter after the bearing is installed. The correct dimension is 43. 210 + 0. 008 mm (1. 7012 + . 0003 in. ). The maximum permissible clearance between the bearing and piston pin (worn) must not be more than 0. 08 mm (. 003 in. ).

Install connecting rod (4) in the piston with the bearing tab groove (slot) (1) on the same side as the cutout (depression) (3) on the head of the piston. 2. Install piston pin (2) and retaining rings (5) in the piston. 3. When old pistons are to be used, clean the piston grooves with an acceptable piston groove cleaning tool. 90
