450C with 75 loader hydraulic hoses

[B Town]

I recently blew out a hose on the boom cylinder on the 75 loader. I replaced all 12 hoses as they appeared original with similar cycles/time and wear. This project has been well over due, outer covers have been cracked and peeling off for a great while(I have owned this machine for 16 yrs). I thought I would list the hoses, maybe someone could use this info in a pinch.

All 12 hoses are 3/4” 2-wire hoses.
All the hoses have one end with o-ring fitting and the other end is a compression fitting.
None of my hose ends are swivel fittings.

The boom up and boom down cylinder hoses are all the same. There are 4 hoses (2 left and 2 right). Part # AT31964. 3/4” X 21”(from thread end to thread end, over all length).

The bucket has 4 hoses per side(8 total Left and Right). The 4 hoses (2 left and 2 right) closest to the bucket are Part # AT31955. 3/4” X 28 3/4 “ (from thread end to thread end).
The 4 hoses for the bucket closest to the tractor come up out of the loader mount. The bucket dump circuit hose is the longer. Part # AT31969 3/4 X 24 1/4” (from thread end to thread end) . Loader will take 2 (one left and one right).
The bucket roll-in circuit hoses are the shorter ones. Part # AT31968 3/4 X 22” (from thread end to thread end). Again, 2 total (one left and one right).

Do your own diligence, the above is how my crawler was plumbed.

Best regards,
Bruce

Those swivel ends are worth every penny. I usually keep my old hoses and in a pinch use them or reuse them on a smaller project like a wood splitter.

Also those ends can be reused by grinding off the compression ring and pulling the fitting out of the hose. I use a cutting wheel on my 4 1/2" grinder...works great! Those fittings out last the hoses many times over. A lot of times the end of the hose gets damaged and the fitting can simply be reused on the same hose by cutting the end off.

Thanks for sharing
