A little fun tonight for the Power Trac crowd....

I was searching Google for something tonight and one of the hits was this:

[SIZE=-1]MossRoad responds. Yikey yikes! MossRoad. Blackwell responds. That is a fitting in the high pressure oil shuttle. The damage is caused by the ball shuttling ...[/SIZE]

O.K., so I am not known for being very helpful

and Blackwell stepped up to the plate

. Without doing a search, anyone remember what this snippet of a post was from?

First one with the answer wins... nothing of course!

Just for fun. No search engines or TBN searches allowed. Honor system. All that stuff.

Ready, set, GO!

It was the Sedgewood discussion of the shuttle valve that was beaten into oblivion. The travel (tram) circuit.

I didn't look or search! Just a quickly failing memory

Here's a link to that post that was made a tad over two years ago.

BTW....never did find out what RPS stands for???

Also, does anyone know of an "off-the-shelf" shuttle valve that could serve as a replacement for this if (and when) the OEM fails? So-far so-good with my machine.

Does your last sentence imply that you check the fittings for wear now and then? Which reminds me, it's about time I checked mine again

If I had known the shuttle valve was a maintenance item I could have caught its failure sooner and a simple fitting replacement would have fixed it. But then I didn't even know what a shuttle valve WAS or that I had or that it needs checking for wear (Power-Trac, are you listening?)!!

Since PT's shuttle valve is integral with the RPS block it may be easier to just replace a fitting now and then than it would be to find and plumb in an off-the-shelf shuttle valve.

Rip,..... I notice that you did not get an answer to either of your questions, both of which are very plain questions.
I wish you lots of luck, I'll keep watch to see if you do get answers. I think I would like to know the same information.

Hydraulics Supply has this shuttle valve for about $16.00

Could you explain what RPS means, and what it does.

I have no idea what RPS means. And your guess is as good as mine about what all goes on in there. Aside from that danged shuttle valve function I've managed to cross paths with ( http://www.coxontool.com/index.php/PowerTrac/ShuttleBall ) it looks like there's a couple or three pressure relief valves, the PTO solenoid, and several internal passageways directing fluid here and there. I do know from my unhappy shuttle valve experience that when it isn't working right there is a loss of draft control and wheel motor torque. As you tram back and forth the shuttle valve supplies a constant flow of oil to the draft control and brake tender alternately from the left and right side of the tram pump (the ball slams back and forth between the fittings acting as a check valve in whichever line is not pressurized at the moment).
