KIT-SEAL 3260502 - Caterpillar

Removal Procedure
Start By:
Remove the aftercooler. Refer to Disassembly and Assembly, "Aftercooler - Remove and Install".
Remove the air inlet manifold. Refer to Disassembly and Assembly, "Air Inlet Manifold - Remove and Install".
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: It is possible to remove the exhaust manifolds without removing the air inlet manifold first. However, the procedure is more difficult. The aftercooler must be removed before the exhaust manifolds are removed.
