New (to me) YM240D

[clemsonfor]

I will have to check the pics I had e uploaded here. I may have posted one on here? I will have to check. I think it was an old non smart phone that I took the pic with. I will look to see what I have uploaded. If not I bet I have one somewhere on a computer?

@California-

I hope you're still reading this thread. I was re-reading the posts in this and my earlier thread for info and things I need to work on when I get back home to where that new (to me) Yanmar is sitting. In post 95 of my other thread you said the loader on my tractor looks to be an original factory Yanmar loader. Is it just the green paint that makes you say that? Any idea where I could find specs for the loader? I'm really after the cylinder info, capacities, etc. I know that leaky one needs replacing. I talked to a place today that said they'd redo one for about $200. I'm game for trying to fix it myself or buy new ones at that price. I'm trying to figure out anything I can about it (including dimensions for the front where it attaches to the bucket, though I can measure that when I get home).

I'm really leaning toward your early suggestion of getting the loader to work off the front pump. I'm not sure if the pump works but I'm going to dig into that this weekend and see if I can't use the reservoir mounted on the side (and already plumbed to that front pump) and the front pump to have a dedicated hydraulic system for the loader. I'd like to be sure I size components correctly, in the event that front pump if it doesn't actually work and I decide to replace it. Some specs on the loader would be really helpful.

Hope you've had a productive week without me pestering you (and other forum members) with constant questions.

Thanks,

There is a reason that auxially front pump is no longer powering the loader. Maybe just broken shear pin or couplers or it could be its busted? Who knows. But someone just didnt go out of their way to disconnect it and tap into the tractor 3pt hadraulics just for a fun weekend project. I would do other things first. Get the bucket like you want get the valves working, rebuild the 3ot hrdraulics, repack the loader cyls and anything else that pops up. Then figure what it would take to get the aux front pump going.

No sense in doing it now. If everything is right on the loader now it will pick up what you need it to. May not be as fast but should be just as strong.

I guessed a model # for that loader but was mistaken. (I cited the loader that's on my YM186D). So took down that post. Here's the corrected version.

I don't mind answering questions but I don't know anything re your loader - I'm pretty sure it's original OEM, made in US or Canada and sold by Yanmar-US dealers as genuine Yanmar like the rototlllers, backhoes, etc they also sold. Look at the set of photos of the clean green YM240D from a CL ad. Same loader, no?

As for specs on your loader, I don't know where you find documentation. I would determine its cylinder size then research similar current loaders - Koyker etc.

I would use the existing hydraulics until it is set up nice, then consider switching. You may not need more lift speed.

Here are the photos of the clean YM240D. I thought your loader looked to be this model.

Just looking at your pictures I want to think maybe that front pto only powered a grapple or some front end attachment. Don't those quick connects toward the front on the loader go back to a control valve coming off the loader fluid reservoir?

Just a little rambling for what it is worth. "IF" the electric clutch is what is missing off the front pto it would first be very expensive if available at all. Next, if you hooked it up direct I am just wondering what kind of drag that would put on the starter having to turn the pump while starting. Might not be a factor, just rambling, just something to ponder.

"IF" you have a seal dealer or good hydraulic shop willing to help you could take your cylinder apart, take it to them and let them supply you with necessary components. I took one of my cylinders apart and took it to a local Crown products dealer and watched a lady install the seal in it. They have a special little tool for installing those wiper seals. Not saying it can't be done without the tool but she made it look easy. She made me remove the old one I guess for liability purposes so she wouldn't chance scratching it.

You're absolutely right about the front PTO no longer powering the pump. There's some kind of coupler missing between the shaft coming forward from the engine and the shaft on the pump.


However, I believe the loader was always connected to the tractor hydraulic pump. I think these two other pumps (the front one in the photos and the big rear-PTO were connected for some other reason- presumably the post pounder and maybe a hydraulic tilt for the pounder. Or maybe a big spinning broom, with a hydraulic adjust for that?

I haven't been able to identify what exactly fits between the pump and the front PTO shaft. I've been told it's something like a 'lovejoy' coupler or shear-able union. That sounds like what you'd want there-something that would shear if the pump bound up. I may have to remove the pump and take it somewhere to get that figured out.

As you and California have both suggested- get it working better as is, before redoing everything. I'm on board with that and I'll start with that leaky cylinder tomorrow. However, I haven't located a hydraulic shop very close to home so if I end up taking a cylinder 45 minutes away to get seals I'll probably take this pump with me to see what they can tell me about the coupler and possibly, the state of the pump itself.

I agree. It looks very similar even down to the yellow sticker on the boom. I'll have to hunt very carefully for a stamp or id plate on my loader at home but maybe it's moot. Finding specs online for this is probably more time consuming and less productive than fixing what I've got. But when the tractor is 3 hours away, and the internet is at my fingertips, I can't help myself. :laughing: That'll change tomorrow when I'm home again.

Don't those quick connects toward the front on the loader go back to a control valve coming off the loader fluid reservoir?

The plumbing is an absolute mess. The quick connect lines you see where plumbed into a valve that worked with the rear PTO pump. The two lines coming off the front pump go to/from the reservoir mounted on the loader frame. Strangely there is no valve for it and the lines basically go in a circle. It could well be they used that front pump until it broke, then just put a bigger unit on the rear because it was cheapear/easier.

Just a little rambling for what it is worth. "IF" the electric clutch is what is missing off the front pto it would first be very expensive if available at all. Next, if you hooked it up direct I am just wondering what kind of drag that would put on the starter having to turn the pump while starting. Might not be a factor, just rambling, just something to ponder.

I looked at the cost of pumps similar to this one and they aren't terribly expensive (I believe under $150) but hadn't thought about a clutch there. The loader is PRETTY slow at the moment which is why I'm interested in getting the front pump to work, but if an electric clutch is needed that might put an end to it- both availability and cost. You're point about drag on the starter if it were constantly connected is something I hadn't considered. However if that hydraulic system wasn't being asked to do anything when starting the tractor would that do anything to reduce the drag? I guess not. The pump would always be providing flow and pressure regardless of any valve being actuated and THAT'S what would cause the drag.

Certainly something to think about.

Go to Dl601-9. Sort of looks like what was there. MF Hard to Find Parts

That does look pretty close, though it looks rigid. Do you think that would provide shear protection? I am interested in getting the front pump going but not at expense of damaging other components....
