W&R Long 3rd Function Valve Sticking

[oldnslo]

What is the flow rating of the WR Long valve or make and model number? Reason for asking is the “Tandem center” spool (P to T, A & B blocked) on D03 valves is one of the lower flow rated spools. I looked at Rexroth 4WE6 G- spool and 12 GPM was failure point. Eaton - Vickers DG4V 3 8C spool was also 12 GPM failure point. The standard performance DG4V 3S failure point was 6 GPM @ 1200 PSI and dropped to 2.5 GPM @ 2500 PSI.

I’m not to sure but I’ll check into that this evening

Thanks for the info. I got my tractor used at 200 hours and it was doing this, so I don’t know how new it was when it started messing up. Does any of your tractors have a backhoe attachment?

Yes, my MX5800 has a BH92 hoe. It's not related to the 3rd function valve problem though since it also occurs on the L6060 without a hoe.

Both my tractors have the 12 GPM W&R Long valves. The sticking problem happens on both valves.

I still think that you should contact WR Long directly. If anyone knows about your issue, they should.

Ok. U took the words out of mouth. lol. I forgot to check the flow of the valve I have on my tractor as the other fellow stated. Should get to it tommorow. Thanks again
