For those of you that have not come across or had the privilege of working on the Ford 4.0L SOHC cam engine you are about to get a baptism in its proliferation in the timing components used. Now before you go off and wonder why I am even trying to tell you about these, know this there are none available in the aftermarket (or at least not that I was able to find). You can buy tensioners, guides and chains but gears are not available from the aftermarket and as you see the proliferation you will understand why. So you will either have to purchase them new from Ford or you are going to reclaim those that are not worn or damaged.

The following instructions begin after the timing cover and old timing set have been removed.
Installing the timing set and degreeing the camshaft will be easier if you loosen the rocker arms so that the camshaft can turn freely. You should be able to turn the camshaft by hand. Make sure that the engine mounting surfaces and your new timing set have been thoroughly cleaned with a good solvent. If you are using a timing set with three keyways, select the appropriate keyway for your camshaft timing specifications. COMP Cams ® recommends the standard timing position for most applications. This position uses the round or “O” timing and keyway marks. Standard Timing Location: This is the same as original O.E.M. setting. Use keyway and crankshaft gear tooth marked “O”.

Following these procedures will guide you in correctly indexing the distributor assembly and initially setting the ignition timing advance.
1: The first step in this procedure is to insure that the #1 piston is brought to the top dead center (TDC) firing position. The firing position is TDC between the piston’s upward compression stroke and the subsequent downward power stroke. To achieve # 1 TDC firing position, perform either one of the following tasks.

Camshaft timing belt must be replaced if cylinder head is to be removed or if drive gears, tensioner or coolant pump are to be replaced. Camshaft timing belts must be stored and handled with care. Always store a camshaft timing belt on its edge with a bend radius greater than 2.0″ (50 mm). DO NOT use a camshaft timing belt that has been twisted or bent double, as this will damage reinforcing fibers. DO NOT use a camshaft timing belt if debris other than belt dust is found in timing belt covers. DO NOT use a camshaft timing belt if partial engine seizure has occurred. DO NOT reuse a camshaft timing belt if mileage exceeds 45,000 miles. DO NOT use an oil or coolant contaminated timing belt (cause of contamination must be rectified).
