Put 6V3029Spacer (11) in the base plate. Put the connect-ing rod on the base plate of tooling (B).Put the connecting rod piston pin bearing end inthe center of the port assembly of tooling (B).Install pin (6) in the center of the bore for theconnecting rod bearings.Install 6V2049 Adapter (9). Put the hole in theadapter in alignment with the hole in the baseplate of tooling (B).Install clamp bar (10) and clamp pin (7).Install new piston pin bearing (5) on adapter(9).NOTE: The old bearing is pushed out by tooling (B)as the new bearing is installed.10.11.12.13.14.Put 5P8645 Adapter (8) in position as shownwith the taper side down. The piston pin bear-ing joint must be in alignment with the hole inadapter (9) and the base plate of tooling (B).Put pusher (4) on adapter (8).Use tooling (B) to push the new piston pinbearing into the connecting rod until adapter(8) of tooling (B) makes full contact with theconnecting rod surface.Remove the connecting rod and the old pistonbearing from tooling (B).Check the piston pin bearing bore diameterafter the bearing is installed. The correct di-mension is 43.210 ± 0.008 mm (1.7012 ±.0003 in.).5-133
