Looking for rear bleeder location for a 420E cat backhoe.

If you are referring to the air purge screws they are on top of the rear axle on each side of the differential. If I have uploaded this correctly, it is a cross section of your axle. Item 7 is the brake piston. The air purge screw should be on the top side of the axle housing, one on each side.
