Plumbing a loader on a Yanmar 276D

[smokinmad]

Looking for some pics of how your 276's loader is plumbed. I got my J.D. model 75 loader mounted on my Yanmar 276. Looking for advise on doing the hydraulic plumbing....

Thanks

what type of loader valve will you use, joy stick, 2 lever, open center, Will it have PB ?.
If you are using open center, there are a couple ways. You can cut the HP line, route it to the inlet of loader valve out of loader valve back into HP to 3 pt.

You can use an OC valve with PB, cut HP line route it to your inlet on the valve. outlet to sump. use PB on valve to operate the 3 pt

See page 270-05-7 in your manual for hookup points.

Have a Yanmar ym186d . Just completed the plumbing for my Yanmar 650 loader as per the manual . But the issue is the 3 pt hitch now comes up way to fast . Is the something I can do to fix ?

No idea how you plumbed it.Was it by the loader manual? Thinking you had a block back at the three point control to tie into.

Thinking you had a block back at the three point control to tie into.

Yes. The US Yanmars come with a divider block just before the hydraulic line goes into the 3-point assembly. The default is fluid comes in one side of the block and out the other side, straight through as if there were no block. If a loader is added, an internal plug in that block is moved to send fluid out one port to the loader then the fluid comes back in the other port and onward to the 3-point. (With this series arrangement, the loader's control has to be plumbed to pass the full volume of fluid at all times except when lifting/curling the loader).

I put a photo in this recent thread showing the block on YM240. My YM186D is similar except the block is bolted to the side of the transmission so the porting isn't as obvious as YM240 but it works the same. I expect YM276D has this later style.

I don't see how plumbing a loader this way could affect the 3-point lift speed.

My tractor is the YM 186D . And the block is mounted on the side and the 1/4 " plug you are referring to is located in the PBY port on the block . And the PBY hose is connected to the PBY port on the control valve . And this PBY port has the PBY fitting installed that the hose connects too .Based on what you are explaining it would suggest I am not getting the full fluid circulation . This explains why I was able to confirm there is definitely to much pressure at the 3 point hitch .Could not see your photo .
thx

I'll repost it here.

Still confused about your plumbing. If you are using power beyond on your loader valve then you also need to have a tank return hose from the loader valve dumping back into your transmission unobstructed.

Power beyond on a loader valve requires 7 hoses. Inlet, PB, Tank return, and 4 cylinder hoses.

Yes you are correct , I have 7 hoses . And the 3 pt hitch did not work untill I hooked the PBY hose up
