Installation Instructions

In order to make sufficient space for the larger aftercooler, a cast rib must be removed. This support can be removed by a variety of methods. One method is described here:

On the 3608 engine, drill a series of holes in the cast rib that is between cylinder 6 and cylinder 7. On the 3606 engine, drill a series of holes in the cast rib between cylinder 4 and cylinder 5. These holes will make the cutting easier when you are cutting through the casting. Refer to Illustration 3.

Use a hacksaw in order to cut through the drilled holes.

Use a grinder in order to smooth the cut that was made by the hacksaw.

Ensure that all of the metal filings are removed from the air plenum.

Install the 7E-3100 Treated Water Aftercooler Group . Use Illustration 2 as a reference. Use Table 1 as a guide in ordering the required parts. Some of the items from the previous aftercooler can be reused.
