Good Evening,

Curl cylinder on my L1720 loader is leaking occassionally. I found a repair kit from Aztec hydraulics.
One is for the complete cylinder part number 70050-01026
The other is the part number for OEM seal rebuild kit (which is NLA from Kubota) 70050-01139.

Has anyone had any experience ordering cylinder seal kits from Aztec and how was the quality/fit.

Thanks,
Tyler

Ended up bringing it to a hydraulic shop that says they will be able to source and install the seals/rings.
Will update with total cost.
Having both bucket cylinders rebuilt as well as the 4 rubber hoses to those cylinders as they are old and rough shape.
