Rocker oil pipe
Rocker oil feed pipe, PN 71-3550, carries oil up to the rocker box on the top end.
This is the rocker oil feed pipe, part number 71-3550. It carries oil up to the rocker box so the rocker arms and valve gear get lubricated while the engine runs. It shows up in the catalog under the FRAME, OIL AND BREATHER PIPES, and OIL FILTER AND OIL FEED PIPES figures, which tells you it ties into the main oil feed circuit rather than being a standalone fitting.

The catalog appearances for this number run from 1974 to 1985, so it's associated with the later unit-construction twins in that stretch of production. If you're not sure whether this is the right pipe for your engine, bring in your old one or give us a call before you order, since there are a few variations of rocker feed pipe out there and they aren't all interchangeable at a glance.
It's a simple part but an important one — a cracked or leaking rocker feed pipe means the top end isn't getting the oil it needs, so it's worth a look any time you're in that area of the engine doing valve or rocker box work.
