ALTERNATOR GP-CHARGING 2942029 - Caterpillar

Start By:a. remove spacer platesb. remove piston cooling jets The front end of the engine is opposite the flywheel end. The No. 1 cylinder is the front right cylinder, and the No. 2 cylinder is the front left cylinder. Put identification marks on each piston by cylinder number. Also mark each piston as to its respective position to the front of the cylinder block. This is done if the piston assembly is to be removed from the rod assembly.1. Remove the cover from the front right side of the flywheel housing, and use tool (A) to turn the flywheel until all four bolts in the bearing caps can be removed.2. Put identification marks on each rod assembly as to its cylinder number. The rods are to be marked at location (X) and the rod cap at location (Y). These marks are on the same sides as the bearing tab slots. 3. Remove bolts (1) and bearing cap (2) from the connecting rod.
Typical Example4. Push the piston up until the piston rings are clear of the cylinder liner. Remove pistons (3) and the connecting rods. 5. Use tool (B), and remove the rings that hold piston pin (4) in position. Remove pin (4), and remove piston (3) from connecting rod (5).6. Remove the bearings from the bearing cap and connecting rod (5). 7. Remove the piston skirt from the crown assembly.
Typical Example8. Use tool (C) to remove piston rings (6) from piston (3).9. Clean the piston ring grooves on the piston with an acceptable ring groove tool. See Guideline For Reusable Parts - Procedure To Clean And Inspect 3500 Series Engine Pistons, Form No. SEBF8059-01, for complete details concerning cleaning pistons.10. See, Use Of Piston Pin Bearing Removal And Installation Tools, Special Instructions, Form No. SMHS7295-02, for more information about removal and installation of piston pin bearings.11. Heat the connecting rod in an oven to a temperature of 175° to 260° C (347° to 500° F). Never use a direct flame to heat the connecting rod. 12. Put 6V3043 Spacer (14) in the base plate. Put the connecting rod on the base plate of tooling (D).13. Put the connecting rod piston pin bearing end in the center of the port assembly of tooling (D). Install pin (9) in the center of the bore for the connecting rod bearing.14. Install 5P8649 Adapter (12). Put the hole in the adapter in alignment with the hole in the base plate of tooling (D).15. Install clamp bar (13) and clamp pin (10). The old bearing is pushed out by tooling (D) as the new bearing is installed.16. Put 6V3042 Pusher Adapter (11) in position as shown with the taper side down. The piston pin bearing joint must be in alignment with the hole in adapter (12) and the base plate of tooling (D).17. Put pusher (7) on adapter (11).18. Use tooling (D) to push the new piston pin bearing (8) into the connecting rod until adapter (11) of tooling (D) makes full contact
