PUSHROD TUBE,48-55 650 DR
Pushrod tube with internal oil drain for the pre-unit 650 twin cylinder block, shows up under PN 70-1505 or the earlier E1505 reference.
This is a pushrod tube for the pre-unit 650 twin, the type that carries an internal oil drain rather than external return pipes. It sits in the cylinder block and head area, sheltering the pushrods that run between the tappets and the rocker gear while giving oil a path back down to the crankcase.

The catalog lists it as PN 70-1505, with the older reference E1505 turning up on earlier documentation for the same part. It shows up in the CYLINDER BLOCK AND HEAD figure for the 6T.
If you're rebuilding a top end on one of these engines, check the condition of the sealing surfaces at each end of the tube along with the seals themselves, since a worn tube or bad seal here is a common source of oil weeping down the outside of the cylinder. The catalog record doesn't spell out further fitment detail beyond what's noted above, so confirm against your engine before ordering.
