BX 23 Relief Valve location

[srossman]

Ok, so I've been following another thread in increasing the relief valve pressure on my BX 23 and I've tested it and found that my pressure is down a bit. I've searched and searched for the location to put in a few shims to increase the pressure and I can't find it. Can anyone give a very detailed location or have a picture of where to adjust the pressure on my BX 23.

Thanks,
Scot

Here is a couple of pages if I can get them attached

Thanks Tommmu, That is exactly what I was looking for. Now if it will just warm up a little bit, I can get out there work on the tractor. 27 degrees is a little to cold to be fiddling with this stuff outside.

Yea I need it to warm up too I "tried" to get to my cabin last weekend and slid off the road on the ice and did over $6000.00 in damage to it.
come on spring!

My BX23 has a bit over 300 hours now, and seems to have lost some of it's grunt. I am collecting the pieces to test the releif pressure myself. The location information is great, but what is the correct releif pressure for this tractor?

Be careful what you wish for. I boosted my BX24 and yes it has more power but it will make it more noisy and it appears my abrupt stop in reverse got way worse.

I think the correct pressure is somewhere around 1850 PSI. I boosted mine to about 1900 -1950 when it was all done. The documents that Tommu provided were dead on. Once I had them in hand it was a couple of hours and the job was done.

Wow- that is important info need to know! The reverse can get worse with bumped up power. . Now I gotta figure if this is worth it or should I get into swapping out shims as needed? If all I am doing is mowing, what happens if I lower the power from the way it is now, will the reverse become softer ?

The two circuits are not related other than the same fluid is used.

Shimming the system rellief will have no bearing at all on the hydro - must be one of those perceived differences.

The hydro reaction is due to no dampening of the hydro linkage as was found on earlier machines.

I don't think the reverse and the pressure boost on the hydraulic is is related.

They have same fluid and sump but different pumps and circuits completely.

I guess Yankee Clipper is a faster typer than I am.
