UNION,BREATHER T140
Breather union for the T140, connecting the crankcase breather pipe into the frame/oil-breather pipe routing.
This is the breather union off the T140, the small fitting that connects the crankcase breather pipe into the rest of the frame and oil/breather pipe run. It shows up in the parts books under FRAME, OIL AND BREATHER PIPES, and AIR CLEANER AND SIDE PANELS, so it sits where the breather routing threads through the frame area and back toward the air cleaner side.

It's a simple connector piece, but breather routing matters on these engines since it's how crankcase pressure gets vented off. If yours is cracked, corroded, or missing, oil will find its way out somewhere you don't want it to.
Our catalog record ties this one to the T140 line across model years from 1979 into 1985. If you're working on something outside that span, give us a call and we'll confirm before you order.
