That left clean nut you see has worked itself loose a couple times in the last year. I'd take a wrench and hammer and tighten it back up. How tight should that nut be?
On the plus side, this is the only leak this machine has ever had.

That's funny blew same hose have the same leak now. Tightened 3 times. Still works it's way loose. I am guessing it needs to be tighter than we got it.

I'm wondering if worn engine mounts is causing everything to shake around more, hence shaking the hoses?

Not good.. u stand a better than average chance in damaging the connectors..
They might seal w orings on the banjo bolt, copper gaskets between the connectors OR the connector itself is the seal..
U should probably see if u can find the proper TORQUE.. (in a rebuild manual)
Good luck.

It's not that it just leaks, the nut it's loose. Like you can turn with your finger. Tighten it and it doesn't leak.

Looks like there is suppose to be a oring.
Like I said, it don't leak if it's tight. It's just that the nut works loose.

Every Takeuchi here gets that leak...my TL150s on the drive pump outputs and TB180FR & TB53FR machines on the main pump outputs.

Since it is a BSPP port, it is important that one not use a SAE/ BOSS/ STOR Oring. There is a difference.

Tightening w/o replacing the O-ring will result in fitting loosening within a shorter period of time.

Is the dealer the only option for that oring?
