Rocker Arm and Shaft Disassembly/Reassembly

Note. Identify parts as they are removed so they can be reinstalled in their original locations. Inspect the rocker arm shaft and rocker arms (see ROCKER ARM AND SHAFT INSPECTION ). If reused, the rocker arms must be installed in their original locations. When removing, or installing the rocker arm assembly, do not remove the camshaft holder bolts. The bolts will keep the holders and rocker arms on the shaft. Bundle the rocker arms with rubber bands to keep them together as a set, and remove the bands after the rocker arms have been installed. Prior to reassembling, clean all the parts in solvent, dry them, and apply new engine oil to all the contact points. When replacing the intake rocker arm assembly, remove the fastening hardware from the new intake rocker arm assembly.

  1. Inspect the valve stem-to-guide clearance (see «VALVE STEM-TO-GUIDE CLEARANCE INSPECTION»(/acura/rdx/i-2009-2012/remont/mechanical/#cylinder-head) ).
  2. As illustrated, use a commercially available air-impact valve guide driver (A) modified to fit the diameter of the valve guides. In most cases, the same procedure can be done using the valve guide driver and a conventional hammer.
  3. Select the proper replacement guides, and chill them in the freezer section of a refrigerator for about an hour.
  4. Use a hot plate or oven to evenly heat the cylinder head to 300°F (150°C). Monitor the temperature with a cooking thermometer. Do not get the head hotter than 300°F (150°C); excessive heat may loosen the valve seats.
  5. Working from the camshaft side, use the valve guide driver and an air hammer to drive the guide about 2 mm (0.08 in) towards the combustion chamber. This will knock off some of the carbon and make removal easier. Hold the air hammer directly in line with the valve guide to prevent damaging the driver. Wear safety goggles or a face shield.
  6. Turn the head over, and drive the guide out toward the camshaft side of the head.
  7. If a valve guide still will not move, drill it out with an 8 mm (5/16 in) drill bit, then try again. NOTE: Drill guides only in extreme cases; you could damage the cylinder head if the guide breaks.
  8. Remove the new guide(s) from the freezer, one at a time, as you need them.
  9. Apply a thin coat of new engine oil to the outside of the new valve guide. Install the guide from the camshaft side of the head; use the 5.5 mm valve guide driver to drive the guide to the specified installed height (A) of the guide (B). If you have all 16 guides to do, you may have to reheat the head. Valve Guide Installed Height Intake: 15.2-16.2 mm (0.598-0.638 in) Exhaust: 15.5-16.5 mm (0.610-0.650 in)
  10. Coat both valve guide reamer and the valve guide with cutting oil.
  11. Rotate the reamer clockwise the full length of the valve guide bore.
  12. Continue to rotate the reamer clockwise while removing it from the bore.
  13. Thoroughly wash the guide in detergent and water to remove any cutting residue.
  14. Check the valve stem-to-guide clearances with a valve (see «VALVE STEM-TO-GUIDE CLEARANCE INSPECTION»(/acura/rdx/i-2009-2012/remont/mechanical/#cylinder-head) ). Verify that a valve slides into the intake and exhaust valve guides without sticking.
  15. Inspect the valve seating. If necessary renew the valve seat using a valve seat cutter (see «VALVE SEAT RECONDITIONING»(/acura/rdx/i-2009-2012/remont/mechanical/#cylinder-head) ).

If the valve guides are worn, replace them (see «VALVE GUIDE REPLACEMENT»(/acura/rdx/i-2009-2012/remont/mechanical/#cylinder-head__valve-guide-replacement) ) before cutting the valve seats.
  2. Renew the valve seats in the cylinder head using a valve seat cutter.
  3. Carefully cut a 45° seat, removing only enough material to ensure a smooth and concentric seat.
  4. Bevel the upper and lower edges at the angles shown in the illustration. Check the width of the seat and adjust accordingly.
  5. Make one more very light passes with the 45° cutter to remove any possible burrs caused by the other cutters. Valve Seat Width Standard (New): 1.25-1.55 mm (0.0492-0.0610 in) Service Limit: 2.00 mm (0.0787 in)
  6. After resurfacing the seat, inspect for even valve seating. Apply Prussian Blue compound (A) to the valve face. Insert the valve in its original location in the head, then lift it and snap it closed against the seat several times.
  7. The actual valve seating surface (B), as shown by the blue compound, should be centered on the seat. If it is too high (closer to the valve stem), you must make a second cut with the 67.5° cutter to move it down, then one more cut with the 45° cutter to restore seat width. If it is too low (close to the valve edge), you must make a second cut with the 35° cutter (intake side) or the 30° cutter (exhaust side) to move it up, then make one more cut with the 45° cutter to restore seat width. NOTE: The final cut should always be made with the 45° cutter.
  8. Insert the intake and exhaust valves in the head, and measure valve stem installed height (A). Intake Valve Stem Installed Height Standard (New): 44.0-44.5 mm (1.732-1.752 in) Service Limit: 44.7 mm (1.760 in) Exhaust Valve Stem Installed Height Standard (New): 44.1-44.6 mm (1.736-1.756 in) Service Limit: 44.8 mm (1.764 in)
  9. If the valve stem installed height is over the service limit, replace the valve and recheck. If it is still over the service limit, replace the cylinder head; the valve seat in the head is too deep.
