Rocker Arm: Installation

WARNING: This page is about a different car, the 2008 Ford Pickup, 2008 Ford F550 Super Duty, 2008 Ford F450 Super Duty, and 2008 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE: To prevent engine damage, keep the push rods in the order in which they were removed. Install all push rods back in their original positions.
    NOTE: Install the copper ends of the push rods up.
  1. Apply clean engine oil to each end of the push rods and insert them into their respective positions.
    2. NOTE: Coat the end of each valve stem with clean engine oil.
  2. Install the valve bridges.
    3. NOTE: Apply clean engine oil to the top center of each valve bridge and rocker arm ball socket.
  3. Install the rocker arm assemblies and the bolts in the following sequence.
    1. Position the crankshaft with the No. 1 and No. 4 cylinders at approximately Top Dead Center (TDC) by observing the damper dowel pin and clocking it to the 10:30 position (as viewed from the front of the engine).
    2. Determine which cylinder is actually in the firing position by observing the push rods for the No. 3 intake and No. 8 intake valves.
    3. If the No. 3 intake push rod shows cam lift, this is the No. 1 firing position. Tighten only fulcrum plates No. 1, 2, 7, 8 per Substeps 4 through 6. If the No. 8 intake push rod shows cam lift, this is the No. 4 firing position. Tighten only fulcrum plates No. 3, 4, 5, 6 per Substeps 4 through 6.
    4. Partially run down both M10 bolts until they contact the fulcrum plate.
    5. Fully run down and tighten the inboard (upper) bolt.
      • Tighten to 61 Nm (45 lb-ft).
    6. Fully run down and tighten the outboard (lower) bolt.
      • Tighten to 61 Nm (45 lb-ft).
    7. Rotate the crankshaft one revolution to position it at the alternate cylinder TDC (dowel again at 10:30 position).
    8. Identify the remaining group of fulcrum plates per substep 3 and tighten per Substeps 4 through 6.
    9. Verify that the pivot foot is centered on the valve bridge.
  4. Install the fuel rail.
