I was re-attaching my H180 loader today and could not get the single point connector to connect. I pulled the connector lever down hard but it wouldn't connect easily as it has always done. So, I put my foot on it to get more force and it finally connected :bigthumb:. Everything was aligned at the time I did this - I suspected the hydraulic fluid had expanded and high pressure was causing the problem.

Once I started the tractor, hydraulic fluid began leaking from the connector. I stopped the tractor and disconnected the single point connector - see pictures below. On one of the connectors I could see a blue piece of plastic on both the tractor side and loader side (you can see this in the photos if you look closely).

Does anyone know what might be wrong with this? I couldn't find the single point in the John Deere catalog - I was hoping I just need an o-ring.

Unfortunately I think your charting new territory. Here is the parts breakdown as shown in JDParts but it does not get down to that level. The FASTER site does not show much either.

If you go to JDparts; 640 Farm Loader PC2361 > 50 Hydraulic Hoses and Lines > Multi-Coupler ST406803. There is a complete breakdown of all the parts for couplers halves. I would post the drawing, but I can't figure out how since parts changed to Parts Advisor :banghead:

May you know how Kenny :flag_of_truce: :dunno::dunno:

My secret link, don't share it! I hope it works for you. With the new PA, you have to take screenshots and post them as pictures, a real PITA for sure and not as helpful.

I know you have a big tractor but is this normal for the single point?

I don't think I ever would have done that. Could you relieve the pressure by pushing or tapping the male ends?

Just wondering since I have no experience with a tractor or loader of that size.

I have never had an issue with the one point like I did the day this happened. When I first pulled the lever down, I met strong resistance. So I pulled the tractor closer to the loader to make sure I had plenty of slack in the hoses for perfect alignment, but I still couldn't pull the lever down. I used my foot gently, it went down fairly easy that way.

I suspected that I might have built pressure in one of the loader lines, but jeez who wants to bleed 4 lines? Next time I feel this resistance, I WILL BLEED THE LINES. Live and learn.

On surfing the FASTER Couplings website, it seems that some of the couplers are designed to be connected under pressure. So, I am not sure that hydraulic lock was my problem. I am currently waiting for a response from one of their representatives as to which coupler/parts I need.

I think JD uses the non connect under pressure 2P series male coupler. The 3P series is the connect under pressure series.
I think the replacement male coupler in 3P series would be KIT3FNP3811/38S
