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.8 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.

first four (4) threads, and (2) small drops in each cylinder stud case
hole.
