Outlet stub-breather
Crankcase outlet breather stub, part number 70-9335 (also E9335), for venting crankcase pressure.
This is the outlet breather stub that fits into the crankcase, part number 70-9335, also listed under the older E9335 designation. It's the fitting the crankcase breather pipe connects to, letting built-up pressure and oil mist vent off the engine as it runs. Being on the crankcase itself, it's a small but important piece for keeping the bottom end venting correctly.

The catalog places this in the crankcase figure, appearing across a few rows in the 1970-1971 span of our records. If yours has gone missing, cracked, or is leaking at the joint, this is the stub to replace.
As with most small alloy fittings on the crankcase, check the condition of the surrounding threads and the breather pipe connection before ordering, and give us a call if you're not sure this is the exact stub your engine needs.
