Ok so there is a hydraulic hard line fro the filter going into the block. It is leaking right where it goes to the block. Bolt seems right but the leak is pretty steady drip. What is the fix? And this is the second time I’ve had this issue. Anyone aware of a guard that can be added to protect this attachment. Seems pretty vulnerable

I think that is a very poor design, just look at the bend in the flat part. Maybe it should have a bend but how much?

Poor design and difficult to replace.

I assume that there is an o-ring behind the plate and the tube may go through the plate and then through the o-ring and into a hole. You can try to make another piece that is trying to apply pressure on the plate near the tube with a u-shape to fit around the tube.

Before that I would suggest you get the tube out and clean the hole in the tractor and the tube. Flatten the plate if possible but don’t stress the tube doing that. Then apply the oring onto the tube and apply a non hardening sealant like Hylomar and reassemble the joint. Then try to support the tube and joint to the tractor so that there is less movement between the tube and case where the hole is in the tractor.

Thank you. So looks like I will be pulling this off today and I’m sure I’m going to find out but this sounds like the only thing keeping this sealed is an o ring? And any shifting of this line causes a leak. It is the second time iv had the first sauce. First I had repaired at dealer. This coupling is right on the belly of the tractor is there any way or like a skid plate that can be added. Something made to protect this weak spot.

Thank you Are you aware of a skid plate or something similar to protect this area. This is a very poor spot for such a weak conection

i do not know of any skid plates for this area on your tractor ?. i have a b2100, and it too has lines in odd places under it. perhaps you could drill and tap some holes in the main frame on the sides, wrap you some metal around and over the bottom, in other words, make a home made skid plate. yes..an o-ring is the only thing keeping this tube sealed, been there, done that a few times putting my b2100 back together..lol.

If you post some wider angle views, there are lots of talented guys on here that can offer good suggestions on how to build one.

If that were mine, I would follow suggestions as posted. Then make up another hold down bracket that would go around the tube and fasten with the same bolt, on top of the original bracket. May need a longer bolt? Something like a distributor hold down clamp of the old days….😀

BXpanded makes belly armor. I am not sure how far forward you need to cover to cover this, but it is worth a look.
