Most Useful Minor Additions to Tractor

[mkr7734]

Hey Kev, tell us that those aren't regular pipe elbows and steel nipples we see in the top photo of your remote hydraulic valve?
I ask because it looks like that what they are... Sorry if you know better, and I am wrong.

Varmint, and DocDryden, glad you called me out on this,,, Nice blow up of the picture,,BTW how did you do that? Can't say if your wrong or not but,
Right, most are schedule 80, some are not just 40. At 2,150 PSI relief and help from my co-workers I worked with for 9 years in Caterpillar engineering on the what will and won't work I took their advice, never had a leak or a blowout. Yeah and I used NPT fittings to. Now if it had 5,000 PSI like the machines I always worked with I would be worried. We did the math. So why worry?? I ain't selling the product. Would be better with steel fittings and O ring boss face fittings but why? Cost would be 300% more for what?? This works.
Over kill is over kill. Heck the cylinders can only handle 2500 PSI anyway, hoses 3,000 PSI. Why have fittings that can take 5,000 PSI??? So you build to what you use. Bet a bunch of arm chair experts will jump me for this one.
I will be the first to know if something blows. :banghead: BTW I have been using this since 2010 with no problems and I have had more Hydraulic oil baths than most. Those years in the test cell could be wicked..I spent 36 years working on Caterpillar machines built in Aurora IL. So I think I have a clue. :thumbsup:

Here is something to look at. Burst pressure is only on relief max pressure. Working pressure is just moving the cylinders. Here is what you can do with schedule 40. Everything is in 1/2" on my system with all hoses at 3/8". Check it out and then make up your mind. Scroll down to see schedule 80. Schedule 40 will work on most compact utility tractor applications.

Wrought Steel Pipe - Bursting Pressures

I am not to worried.

I'm not an expert at anything, I don't know if your right or wrong. Just know what I've read here on TBN about pipe fittings. You'r right about saving some $$$. I just bought a small fitting that cost me $12. If I went with steel pipe it would cost about 89 cents

It's a nice neat plumbing job and I agree with you on the pipe & fittings.

Schedule 80 pipe is rated for 1750PSI working pressure. Yes, you can probbaly get away with it but its not recommended.
Have you put a pressure gauge on the inlet to the valve to see what pressure it normally runs at?
Personally, with the price of fittings from Amazon or Surplus Center (Surplus Center) I don't see any reason to risk using fittings with a working pressure that is lower than the system relief pressure.
Our L3830 will push over 2000PSI when its cold, you bring the engine up to 1500RPM and try to move something.

Here's one of my most useful mods I'm working on. Kubota Grand L cab mirrors on a kubota l3901. Will help a lot with not having cars sneak up on me while box blading my road.

Not trying to argue but going to share my thoughts. I haven't had many problems with pipe so far. Running it on my old Allis chalmers wd45 from 1/4-1/2 fittings so far so good. But I could shut all hydraulic power off if I wanted to cause I got it running from the original valve because of special fittings on the valve. But I'm sure I don't put as much run time and work the hydraulic system as much as you guys

It is to get more dump without sacrificing curl.

Is it OEM, or an add-on?

I am wondering if I could add them to our loader for the same reason, and whether it would work on it...

Aaron,
Did you read anything I posted?? ,,,14,000 PSI burst pressure. ,,On the chart???? If I had deep pockets maybe I would agree. JMHO. You guys are everywhere. Cold or hot relief PSI is relief PSI. Your L3830 or anything else does not change the Physics of anything. BTW running the cylinder in and out is nothing when I checked it the limit is hitting max relief pressure. But you know that.

I think all anyone has to do is read the chart. Even if you think my 36 years of working in the field is BS
I am not going to just throw money away because someone with limited knowledge wants me to spend on something I don't need to.
We are falling way off the OP question here. Have a good night.

And it would work! :thumbsup:
