2004 Ford E-250 Camshaft Parts Questions & Experts Answers

• Q: How to service and repair the camshaft on 2004 Ford E-250?

  A: Service and repair operations for the camshaft begin with timing chain removal followed by preventing rotation of crankshaft or camshaft during cylinder head installation because this prevents severe valve and piston damage. The service procedure begins with removing the roller followers of the camshaft. Service managers must remove the bolt then extract the sprocket of the Romeo platform engine (4.6L). Maintaining the original positions of the camshaft bearing caps requires you to note down their positions before removing the bolts and bearing caps together with the camshaft. The camshaft bearing caps must be cleaned and inspected while specifically checking that one cap has an essential oil flow restricting groove without foreign materials inside it. When working with the Windsor engine (SAL) you must implement bearing cap handling and evaluation steps in the same manner. Installations should eliminate the use of metal scrapers or abrasive tools on sealing surfaces since valve cover mating surfaces must be cleaned with silicone gasket remover and metal surface prep using a plastic scraping tool to remove old sealant. Clean engine oil should be used to lubricate the camshaft journals as well as bearing caps before the original positions are used for installation; bolts should be loosely installed before final tightening according to the specified sequence. You must tighten the bolt securing the camshaft sprocket on Romeo engines in two stages according to the instructions which specify torque to 40 Nm (30 ft. lbs.) followed by an additional 90-degree turn. The Windsor engine installation of camshaft and bearing caps needs to be performed a second time. You should install the camshaft roller followers followed by the timing chains as your last step.
