STEP 4: Breather - Installation
• Obtain:
• The breather assembly.
• Two bolts No.4400. (all have lock patches)
• Install the breather baffle assembly into the support plate. See Fig. 6, page 6
• Fit the breather cover with the two bolts.
• Torque the bolts, in two stages, to 120-156 in-lbs.
• Repeat this procedure for the second cylinder.
• Pour approximately one ounce of clean 20W50 H-D engine oil over the roller-end of each
rocker arm.
Note: Be careful to keep the oil off the gasket surface.
STEP 5: Top Cover - Installation See Fig. 6 & 7
• Obtain:
• A top rocker cover (Chrome) No.1208-1318.
• A top rocker cover gasket No.17386-99.
• Six chrome rocker cover bolts (three short three long) and six chrome washers.
• Make sure the gasket sealing surfaces are clean, smooth and dry.
• Place the gasket in position on the lower rocker cover.
• Place the top rocker cover in position over the gasket.
• Apply a drop of blue LOCTITE #243 to the first few threads of the 3 long bolts (1286-1367)
and 3 short bolts (1286-1352).
• Thread three short bolts with one flat washer (1286-1397) through the left side of the top
cover and into the lower cover.
• Thread the remaining three longer bolts, including the washers, into the right side of the top
cover and into the lower cover.
• Snug the two short bolts while holding the top rocker cover in alignment with the lower
rocker cover.
• Torque the bolts to 9 -12 ft-lbs (108 - 144 in-lbs, 12.2 - 16.3 Nm) See Fig. 7
• Torque in two stages, the first being about half the final torque.
• Follow the torque sequence shown in the illustration.
• Repeat these steps to install the second rocker cover.
