753 Backhoe hydraulic question

[toolgarage]

Morning all!

I have a 4400 gasser/753 backhoe with leaking backhoe hydraulic hoses that need replacement. Machine is 100 miles north, and I'm trying to determine which crowsfoot wrenches I need to buy to get the hoses off the hoe.

I have the manual but NADA mention of wrench sizes. Any help would be greatly appreciated.

Thanks!

If you want to be 99% sure you are covered, I would say every size from 9/16'' to 1-5/16'', same sizes in open end wrenches. Who knows what fittings and adapters might have been installed over the years.

Been awhile but I think 1 1/16 and 1 1/8. As far as crows foot, get on amazon and look at 60 degree open end
wrenches. You'll be glad you did. Good Luck.

1-1/4'' for certain for the numerous #12 JIC fittings. And as already stated, some angle head wrenches are almost a must.
