STEP 1: Preparation
• Inspect the entire surface of the studs for damage. See Fig.5
• Minor scratches are okay in the body of the stud.
• The threaded portion of the studs must not have deformities that stud
would cause binding between the cases or head bolts.
• Set aside and cover.
STEP 2: Inspect the oil filter o-ring sealing surface
• Sealing surface should be smooth and flat.
• If necessary clean thoroughly, set aside and cover. See Fig.6 for Engine “A”
• Inspect both threads for any burrs or dents on oil filter adapter No.1486-
1835.
STEP 3: Base Gasket Surface Preparation
• Clean base gasket surface (case deck) with a clean lint free cloth
and (denatured alcohol/isopropyl alcohol)
• Make certain the cylinder seating surfaces of the cases are
smooth, clean and dry. See Fig. 9.
• Confirm the eight stud holes in the cases are empty, clean and dry.
STEP 4: Stud Installation: See Fig.7 & Fig. 8.
Note: These studs are not designed to be an interference fit, however there
may be slight drag on some studs as they are installed into the case.
• Each stud is installed with two (2) small drops of Loctite 620 on the first
four (4) threads, and (2) small drops in each cylinder stud case hole.
