New Holland tc40
During a snow storm I developed a leak on a hard line for the loader control. Can these lines be replaced with regular hydro lines or do they have to be a hard line? Any info is greatly appreciated Also if anyone has a part # for that line

NH Part Number 86573710... for TC40 & TC40D Hydraulic Tank Line for Two-Spool Remote Control Valve

They are available but pricey... link...
Partspring - Messicks has them also

Just confirm it is #23 in the diagram you are looking to replace but all the lines are in that diagram

My choice would be a replacement steel line... less likely to catch / snag on something & no rubbing issues.... But... You can use a hose just make sure it is sized properly & pressure rated correctly... may need a 45 or 90 degree fitting on the tractor end to make sure there is clearance & it doesn't rub...

I had a leak like that near one of my fittings and I tightened the fitting and it stopped. I assume you already tried that.
