Note:It is critical during installation to ensure the bearing rearcap and cylinder head alignment is correct and the mating surfacesare flush.

Ensure that all sealing material has been removed from thecomponents, and the sealing surfaces are clean and free ofcontamination prior to applying the sealer.Install and align the rear cap within 20-minutesof applying the sealer.

Note:Apply the sealer to all locations centrally locating the beadon the rail.

Run bead to 5.0-mm, dimension a, as shown.Where the cap ends on the perimeter rail, extend beadapproximately 4.0-mm beyond edge of cap.Run bead, dimension c, 32-mm from the edge of thecylinder head as shown.Run beads, dimension b, 20-mm from edge ofcylinder head as shown.Apply a 2.5-mm bead of sealer to the cylinder headat the number 6 intake camshaft rear cap mating surface. Refer toAdhesives, Fluids, Lubricants, and Sealers.Install the number 6 intake camshaft rear cap.Tighten the cap bolts evenly to5-Y (44 lbin).Tighten the cap bolts evenly to10-Y (89 lbin).Back the cap bolts out 120-degrees.Tighten the cap bolts evenly a final pass to10-Y(89-lb-in).
