Disassembly Procedure
Start By:
Remove the fuel injection pumps. Refer to Disassembly and Assembly, "Fuel Injection Pump - Remove".
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
When the fuel injection pumps are disassembled, handle the parts carefully. Do not damage the surfaces of the plungers, the barrels and the bonnets. Any scratches will cause leakage inside the fuel injection pump. The plunger and the barrel for each pump are made as a set. Do not intermix the plunger of one pump in the barrel of another pump. If one part is worn, install a completely new plunger and barrel assembly. Be careful when placing the plunger into the bore of the barrel.
