Repair: Rear steel hydraulic line above PTO BX

[B737]

This fitting started dripping today while I was out helping a friend. I only noticed because I started seeing drips on his driveway. Had I been in the yard I would have never seen it until it got worse. After the job, I noticed the compression fitting was already tight. Tightening it only made it drip faster. Did a quick google search, this appears to be a common failure on BX, a few threads popped up on TbN.

When I removed the line I could see the steel hose was split at the flair. I think Kubota makes a replacement hose for this that is superseded by a rubber one. I had my local hose shop make me up a rubber one and it seems to be doing ok. I'll know more after some seat time.

yup I replaced lots of those metal pipes they always crack. there is significant vibration in the pipe from pressurized oil passing thru it which causes it to crack. It will crack again if it's replaced with another metal pipe. Needs to be a hose assembly not a pipe. IIRC all the new ones are hose and not pipes.
