It would be nice to post some pics of the issue (even if we wouldn't be able to make out the cracks in the picture). I suggest using a pointer to indicate the area that cracked. I have found that if it happened to yours, it can and might happen to all.
One thing you might want to watch (this is kind of how you personally operate your machine), is how much idle time you give to your tractor. The 2 cyl Deutz has certain RPM ranges that vibrate and those ranges will vibrate different parts of your tractor. If for example, you set your throttle to extreme low and then leave the tractor to go get a coffee or a tool, parts of the tractor (like your hydraulic filter) could be shaking away the whole time. Just think about it. I added a tail pipe to my 1430 to direct exh to the rear, and if I hit a certain RPMs, it shakes a lot, I bump it up a few and smooth as asphalt.

Now I will have to check mine for cracks but both of the PT1850's have this problem. If it was a hairline crack on mine, I would expect the leak to get worse as I tighten unless the crack is just within the seal area. Kudos for finding the crack.

The leak would not be in hose connections etc if the leak is reduced by tightening the filter.

Congrats! And TU for posting. I have yet to change my filter and I am dreading it for the reason u have brought up and my lack of knowledge about proper bleeding procedures.
I have contacted PT for workshops on proper service/maintenance/issues troubleshooting several times but I am not getting anywhere with that. This forum is the way. Haha

I wouldn't let the filter change worry ya. This thing here that happened to me was just a freak thing. When I first bought this back in 2016, someone told me to tighten it up a full turn after it was snug, so I done it. Well, when it come time remove the filter, I couldn't get it off. It took me and two other men to get the thing off. We had to poke a bar the hole way through it, because the filter was so crushed from trying to get it off with the filter wrench. Anyway, I think that is what caused this thing to crack.

Yeah, that true. Every time I re-tightened the filter there was no difference in the bubbles coming out, so I knew that the filter wasn't the problem.

Yeah, I know what your saying about the rattling at low idle. As soon as the idle is bumped up a little the rattle goes away. Have you tied any of your hoses from moving around too much?

Here is a picture where the crack is. You can the litte red dot of Permatex Thread Locker.

Can't open your attachment pics for some reason.

I look at my hoses every once in a while. Not looking forward to high hours and my first oil leak. I wonder when that will be? If you ever read the write up from back in 2002 from (I think it was) Foxcon where is 1845 burnt up, now PT covers the positive battery cable inside a hyd hose and the fuel line to the pump and chafe hose in certain spots. I guess it wasn't worth covering the entire fuel hose, and the little pieces tend to move up and down the hose, so.....

Yeah, I know the battery cable your talking about. I noticed early on how it shook around allot, so I attached it to the hydraulic hose that goes to the the filter housing, which is right beside it. The other hose that I wire tied was the fuel hose with the gray braided cloth. It was actually bouncing around right at the tip of the engine mount bolt, in which over a few years of that it wore some of that cloth braiding off. So, I'm glad I caught that! The wire that goes to the right head light, which runs through the back/top of the FEL Control Valve I gave yet found a good way of protecting that wire. The wire gets touched/moved by the wobble assembly right at the top of the control valve. I'm not sure what went wrong with the picture. Here, I'll try it again.

For me, it is the control wire for the starter solenoid - have repaired that 3 times. The wire eventually breaks in two at the connector due to vibrations. I added extra strain relief to spread out the forces. We will see if that works any better.
