Suggestions for hydraulic gauge (for diagnostic purposes) I think at/under 400 psi

[Richard]

I don't know first things about them (nice brand, trash brand...)

Have an International 1066 that has a MCV valve on it. I want to test some of the pressures on it.

Any brands to go towards and stay away from??

The IH should be standard size threads. I also have a JCB backhoe that has (I"m told) "British" metric....so if the gauge would do both, all the better.

Just about any glycerine filled gauge you will find will have 1/4 NPT male threads. You will need a high pressure hose to adapt from that to something like -4 JIC female then adapters to fit whatever you are testing. Consider a hose up to 6 longer or more so that you may observe the gauge from the operators seat of the machine. You will need a gauge that reads in the 0-1000 psi range for low pressure testing (MCV circuits) and another in the range of 0-5000 psi for hydraulic function circuits. Gauge brand is not critical.

I thought I read somewhere that the PSI numbers should be under 400 therefore, my interpretation was a lower PSI reading would be better (higher resolution)

??

 

[RickB]

Your choice. The next time you need a lower pressure gauge the spec might be closer to 500 and your safety margin disappears. A 500 psi gauge would work on the IH.

Edit: ASTM standards suggest observed values should fall between 25% and 75% of the gauge range. A 1000 psi, 500 psi or 600 psi gauge should perform satisfactorily to measure MCV pressure. Lube pressure would require a lower pressure gauge to measure accurately.

Um, my system bypass valve is set at 2,100 PSI (or there about on my MF at pump body) .. I would think a 400 psi system probably does not have much work ability....

This would indicate you pressures are more then 400PSI

It is regulated circuit pressure for clutch packs.

Ok... Did not know that...

Not knowing much about this, I'm suspecting I was getting this confused with the other.

So, to help my ignorance.... have any brand suggestions? (prefer to stay away from China if that's possible anymore)

I can’t advise you on that because every time I have bought gauges I’ve bought on price and have yet to be disappointed. Spend as much or as little as you feel comfortable with.

I try and get a gauge where it will read in the middle for my anticipated reading. If I expect to see 500psi I would want a 1000psi gauge. As RickB said they are most accurate in the middle 25% -75% of their range.
