<font color="blue"> Have any of you been flushing out the gauge/hose assembly before you use it with fresh hydraulic fluid? </font>
I didn't.

Spencer, I still have the guage and asked Mosey ( in the goodbye BH 246, Hello 7308 thread) to PM me with his address and I will ship it to him. Bill C

Boy,that gauge is making the rounds, has anyone tracked where it has been and what the different readings where? Once finished with its trip, a tally reporting the various findings might prove interesting..............seems like lots of variance with the settings on this tractor.

Things that make ya go hmmmmm.

I sent my address to Bill via PM. I'll post the results here when I get done. Thanks!

Bill, no hurry. I won't get a chance to use it for at least a week anyway. Plus, I want to do some more "pre-testing" before I make any adjustments (if I even do make any adjustments) so I can see what effects any adjustments have on the performance.

The guage is on it's way to Mosey in Indiana. Bill C

I got the gauge yesterday.

I did some testing of the FEL before hooking up the gauge. I tried to lift the front wheels off the ground with the bucket fully curled back and using only the lift arms and the front wheels stayed on the ground, but it did take the "squat" out of the tires, so it lifted the front end some. But, the lift arm cylinders were fully bottomed out. I was on a level concrete floor and had the tractor in neutral and the brakes were not locked. I tried it at just above idle and at 2600 RPM and it didn't make any difference. Next, I used the bucket cylinders and rolled the bucket down (dumped) and it easily lifted the front tires way up off the ground. I raised the bucket with the lift arms (so the front wheels were back on the ground) and left the bucket in the dump position, then lowed the lift arms again. With the tractor running at 2600 RPM, it would lift the front wheels off the ground a few inches, but would not bottom out the lift arm cylinders.

I haven't checked the pressure yet, but hope to get to it this weekend.

Spence,

I noticed that fluid is visible inside the gauge dial, it that the way it's supposed to be?

How do I go about flushing out the gauge and what is the purpose of doing that?

Also, is it best to only hook it up to the female quick coupler coming off of the tractor rather than putting it in line? If I understand correctly, then I don't need to put a load on the FEL if I don't have the gauge in line, just hook it up to the green circuit and move the control lever forward - is that right?

Here's a quick summary of the readings so far. As you can see, the factory settings vary a lot!

Yep, I went into this blind, that's why I don't have a 'before' measurement.

Danny, fluid is visible inside the gauge because it is a high-quality glycerin filled gauge. The glycerin prevents the needle from vibrating so you get a clearer reading. I use a gauge like this on my pressure-increasing-pump for my reverse osmosis water filter.
