hydraulic power loss after detent change

I just changed out my detent assembly on my float valve (LA352). In the process I took off one of the hydraulic hoses directly near the detent. About 4 oz of fluid came out. I reattached the hose and might have attached it too tight as it twisted a bit towards the end. I then tested out the loader and the bucket no longer lifts the tractor off the ground and its starting to smell hydraulic fluid. No leaks. I'm wondering if one of the following is the problem:
1. Need to bleed air out of line?
2. Need to loosen that single hose as being too tight could cause a restriction?
3. My detent assembly isn't on 100%?
4. Wheel bearing grease has contaminated hydraulics?

Tractor is 2003 B2410 with LA352. Replaced with new detent kit from Kubota. Used wheel bearing grease on assembly.

Wolfman you are indeed correct. The rig is back to operating like it should, that is, can't keep the front wheels on the ground! Granted its working, but I still think I got something mixed up. The assembly kit has a sleeve in which the ball bearings ride in. On my old one, rusted up, the ring on that sleeve was towards the loader side. The Kubota diagram also shows the ring on that sleeve towards the loader side. Under this ring is a step. When it wasn't working properly, the ring was as Kubota diagram shows (towards loader). After I read you post I decided to simply swap the sleeve such that the ring is towards the valve. This worked. Any thoughts why my old one and this Kubota diagram shows that ring facing towards the loader side? The parts are identical. Maybe I have the spring upside down and its just compensating? Thanks so much!

BTW, the hydraulic fluid smell was my paranoia combined with a 90-degree day. But when I did have that ring pointed toward the loader side the loader was constantly wanting to go up, in addition to the loss of power in the downward position.
Thanks again
