Hydraulic hose bulge

[CutTheHolesOut]

Got this old backhoe last year for pennies. First thing I did was new filter and fresh transdraulic fluid. Probably put on 20 hours last year and an hour this week. Today I just needed to dig a small hole to plant a tree. I was able to finish the hole, pack it up and put the tractor back in its home before I realized this huge bulge. What’s going on here? It amazes me that I was able to finish digging the hole.

Probably dont want to be in the way of that when it lets go.

Wow, it grew a kidney! Cycle the levers (engine off of course) and that should shrink back down. You have to relieve the pressure anyway before you take it apart. Good thing it didn't let go.

Easy fix: new hose. Shops all over, that can make a new one. Have them reuse the ends.

I wouldn’t reuse those. Small ends aren’t that expensive and those are pretty roached anyway.

I'm with 4570Man. NEW hose and NEW ends. You might want to take the old ends with you. So they get the correct new ones.

Wow quite a goiter. If that was mine and keeping with the small investment theme I’d probably pick up a pre made hose assembly at Blains, TSC or similar farm store. That is if that’s just a NPT thread going directly into cylinder port which it appears to be. Other end would have to be npt also. Get the assembly with swivel at one end for easy install.
(MxMS).

What’s going on here?

The inner core has sprung a leak, and the oil is getting between it and the outer layer. New hose time.

Definitely time to replace that hose. On a hoe that old, I would also check the other hoses for signs of deterioration as well.

Thanks for the replies. Gonna head to TS this week and see if I can’t find something to throw on there. Probably due for a fluid change anyways so I’m not too upset about it, especially being that she didn’t bust her guts all over the only pair of pants I have without holes in them.

I'm in agreement with replacing the whole package: hose and fittings. I'd also start looking at the other hoses and maybe replace one or two each year as a precaution.
