JD300B hose from Hydraulic filter to Transmission Help?

Axl2011 · Jul 30, 2019

Where could I find this hose, or what could i use? I can not seem to find low pressure hydraulic lines and I do not want to leave my system drained for days.

Thanks!

I guess that would be true. Lol I live in East Liverpool, Ohio (I will go update now)

Try NAPA or your local JD dealer.

I went to NAPA the guy was unsure about if the hose would handle hydraulic fluid.. The dealer I originally went to said they don't have hoses, So I am calling around again today. If no luck I will order from the site above.

My main concern is that I am unsure if leaving the system without fluid for days would cause harm or not?

Likely not.. as long as you don't start it up and try to run it (figure you know that already).

Yeah. I did end up finding a place nearby that does make them so I am going there to get one! Thank you for that site also!!

May be a stupid question but are you to bleed air out of hydraulic lines? The backhoe still moves kind of slow after changing filters and the milky hydraulic fluid to fresh fluid.

Thanks again!

Air in hyd hoses/cylinders will bleed out when cylinders are cycled through normal operation. I suggest to check stand-by pressure which should be 2250 psi.

How would I check stand-by pressure? Sorry if I sound stupid. New to all this and learning. I appreciate all the help from everyone!
