PUMP GP-GEAR 2794699 - Caterpillar

The procedure that follows is not to be used on cylinder heads, fuel system housings, inlet and exhaust manifolds or hydraulic system components.
To start, put a mark on the area in which the plug will be used. Use a center punch to make a small hole in the castings to start the drill. Drill and tap the hole to the correct size for the pipe plug to be used. Put 6V1541 Quick Cure Primer on both the threads of the pipe plug and the tapped hole. Put 9S3265 Retaining Compound on the threads of the pipe plug. Install the pipe plug and tighten it to the correct torque. See Illustration 1.
The pipe plug must be long enough to be above the front and back surfaces of the casting wall to make sure of the correct thread engagement. Grind the top of the pipe plug even with the casting surface. See Illustration 2. Put paint on the ground surface.
