Advise on replacing L3301 HST oil cooler line (inlet)

[tcpkubota]

I have a small leak on the oil cooler line on my L3301 tractor. the leak appears to be coming from around the hose clamp directly behind the power steering shaft . I tightened the clamp but that did not stop the small drip leak. I know I will need to remove the battery to access the lines going to the cooler. Any advice on how best to change the line. Do I need to change both? Are there any "tricks" or helpful advice to get this job taken care of?? Many thanks for any advice.

FWIW. one oil cooler line on my L3901 leaked right out of the box. Tightening the clamp fixed it. Removing the battery to access it was trivial.

Oil cooler hose leaks seem to he a common issue in those models.
