jubilee issues

[jonesnjones]

sorry about the confusion gents; my issue was the unloading valve wasn't free. I honed it out and made some adjustments with the linkage. I'm not sure exactly what the crank driven pump is that's on it. all I know is I pulled it off an 800 ford. it has worked since I put it on and is finally working now. I still have to have about 10 lbs. on the drawbar for to keep it from creeping up but I can live with that. in case u are still wondering I have it plumbed directly from the pump to the port. nothin in between. may not be oem but it's working good now. thanks for your time. I will try to get some pics of it if you would like.

from the pump to the port? what port? there are dozens of ports on the tractor??

a picture would help.. or a detailed description of where the pump is sucking oil from and pushing it to..

reason I mention this is I don't hear of a relief valve in the crank driven system.. the relief for the side mount engine pump is inthe base of the center casting.. and there's no access to that unless the pressure port has been t'd at the manifold somehow.. or the side pump completely eliminated and an adapter plate made to feed/return the oil from the front pump.

without a relief.. it's a problem waiting to happen as soon as that unloader REALLY sticks one day.. and the engine is still turning, thus crank pump making oil.. and nowhere for it to go.. = split hoses, cracked castings.. etc.. etc..

it is sucking from the tractor and pushing back into the tractor...

no but really i wont to see how that thing is hooked up i might wont to try it in the future

my only real guess is that he is using the hyd drain port as the suction for the pump, and then plumbing the output into the side of the center housing just ABOVE and beyond the relief valve that is inthe base of the center housing.. where it then feeds the top cover along with the oil from the oem pump. in this fashion the unloader is having to deal with alot of extra oil capacity.. since it was designed for 2.85gpm. plus there is no relief in the aux pump circuit, as the relief is inline with the piping thru the trans and into the center section directly. that scares me. no relief is BAAAAAD!

i agree with u 100 percent i would think the front pump would do some serious damage over time from the high valve it puts out. i was thinking they might have cut the tubes that connected the oem pump the the trans and spliced it there some how. but i would like to see a picture. i know i have only seen one done like this and it was an 8n and worked about 5 mins tops and stuff started coming apart inside the lift top. and would this be dangerous i wouldn't wont to sit on top of all this contrapasin if a plug comes out some where it will hurt

yep.. I have seen that.. the oem pump gone, then a dummy plate bolted to the flange where the oem pump would connect.. this plate then has a suction and pressure fitting of choice welded or brazed, etc.. to it.. then you just hookup however.. IE.. JIC.. pipe swivel.. etc.. etc.

if he is doing it like that at least there is a relief in the system.. however same problem exists.. relief is designed for a 2.85gpm system as well.. at full relief, if the pump is way high volume you can still have issues.

hopefully it's a lower volume pump.. say 6-8 gpm, then there is a restrictor orifice inline, and it us using a dummy plate to feed the oem pump connection, in leiu of the oem pump. that's the only safe way I'm seeing it, unless it was as mentioned before AND has a relief inthe system he is not telling us about.

that's why i want to see a pic.

sure hope he doesn't grenade that jube. their hyds are different than the 55+ 00 series and parts are getting harder to find every day.. plus.. all that is just a few inches away from where some important parts are setting.. like legs, but.. 'the boys'.. and none of them are replaceable should a high pressure hyd leak forcefully occure due to an underengineered hyd kludge that 'works'.. would hate to see the guy get hurt.. oil injected under the skin is bad news, and high pressure oil at a few inches can cut like a blade and lay flesh open easilly.

i seen a man have some oil on his hand and blowed it of with a air house and it forced some under the skin on the tip of his finger where he had a little cut they ended up having to cut of his finger because it got a real bad infection

yep.. that's why i like to check for leaks on pressurize dlines with a piece of cardboard... way safer!
