3/4 Hydraulic line pressure

[racerboy832]

I am replacing a blown 3/4 hydraulic line that is the main feed from the pump on the front of the motor to the controls for both the backhoe and loader on a John Deere 450. The line is 72" A premade line is approx $35 and the local shop wants $105. The local shop says theirs is 3100psi working pressure. The online ones say 2250psi working pressure but Burst 9000 PSI. I could be wrong but I thought most of the reliefs are set around 2k. This hose is a MF er to get back off. Any insight on if the premade one from Northern or Surplus will be ok?

Assuming that this is a 450 trackloader (like http://www.deere.com/en_US/docs/construction/non_current_products/crawler_dozers/450C.pdf), Deere lists the relief valves as being set to 2250PSI. The hose you are seeing online which is rated at 2250 is probably 100R2AT (2 wire). The hose that the shop is making is probably 100R12 hose (4 wire).
Try DiscountHydraulicHose.com they will make a custom hose for you, it looks like they would charge $66ish for the parts. I don't know if they charge to crimp the ends on the hose or not.

I believe they charge $10 for crimp plus shipping. Basically I am better off just going to the local place and have it in 15 min. Thanks for finding that spec sheet link thou.
