scrape surfaces, as this could result in leakage. Install breather mounting studs into crankcase if removed during
disassembly.
2. Install breather chamber gasket as shown. Assemble and install breather assembly components as illustrated.
Make sure filter does not extend above top surface and all parts are properly aligned.
3. Install M5 nuts onto studs, then torque using sequence shown to 12.4 N·m (110 in. lb.).
4. Lightly oil lower end of breather hose and install into hole in breather assembly. Cover should be situated between
2 raised rings of hose.
