My Yanmar 2620

[wmcelwee]

Hey everyone, I'm new to the forum and new to tractor ownership. I purchased a 2620, looks like crap (all the lights busted off, paint faded and cracked) but runs well and everything mechanical is sound.

I haven't found a lot of info on the 2620 but I've ordered the appropriate books from Hoye.

I do have some questions:

What's the max capacity for the front loader? What about the 3-point?

Do any of you folks have experience with a root grapple on a YM? I'm planning on purchasing a 48" grapple soon in order to clear out a warehouse full to the brim with scrap wood and junk.

Has anyone used a 60" loader bucket on a tractor this size?

TIA for any answers,

wmcelwee

Check out this thread on the loader. It " might" give you a little information

Welcome. I can't answer any of your loader or backhoe questions since I don't have them. As far as capacity there are charts around, I am not sure where they are. I would just buy a five gallon bucket. It will holdbat least 4 gallons and maybe five.

My ym240 (same as a YM2000, 20 pto hp) has a bucket 5 ft wide but not real deep. I don't recall I've ever scooped a load - gravel or anything - that I couldn't lift easily. But this is wide enough that it doesn't dig easily into hard ground.

Just guessing but for a 2620 I would say a 5 ft bucket if it will always carry maximum-weight loads such as mucking out a stable or taking gravel in for a septic system contractor. Or digging in the earth. For the rubbish you described, a 6 ft wouldn't be stressed but that larger bucket will take more room to maneuver, so it depends on your long term mix of applications.

Fredricks don't even list having a 2620. They show to have a 2610. If this is close to your tractor, it shows koyker 140 or 150 loader.

What loader do you have ?

I have a 3110D and all I have is a 5ft bucket. Some times, (with full bucket) It's all the Koyker loader wants

I don't have a dedicated grapple . I have a thumb which bolts to the bucket

You do not mention the loader brand that is on the tractor, nor where it gets the hydraulic fluid from. All will play a part in what the loader will lift as will how far in front of the pivot pins the load is located.
The amount of hydro pressure generated by the pump is the biggest factor in what your loader will lift after the loader specs. Flow rate once min required is met will mostly result in speed of operation.
There are lots of issues related to your loader questions and you provided only that you have a loader.
One caution that was kind of address by another person is size of your bucket has many possible effects, some include—-wider requires more space to move about. A wider bucket is often a deeper bucket and that may be an issue.
Also the closer to max weight you make your loader work, the more you keep everything close to its upper limits of operation, the more likely you are to find any weak spots in the mechanical process. Such as worn metal and rubber hydraulic lines, valves, pump, cylinders, and the list goes on.
It is your machine, use it as you wish, but there are reasons why we have machines that range in hp from low 10’s to 100’s

The loader on it almost seems like it came from the factory with it, but I don't believe they were ever produced that way. It's painted red, same as the tractor, and there are no descriptive markings or stickers on it anywhere. At any rate I've got a lot more to read and learn.

Thank you all for your replies thus far.

Post a picture of it. People will tell you what it is or if it's home made. These guys know what the loaders are o. These things.

I think the Yanmar-Japan loaders had curved arms in that era. Does this one?

No, it has straight/angular arms like a koyker. I did actually find a sticker on it, saying it is from 'Apple Implement MFG'. Here is the only pic I have of it at the moment:

But now we have bigger problems. When I bought it, it started and ran fine for the first few days of use. Since then it has become harder to start and hasn't run well at all. This issue has progressed and quickly gotten worse. Now, if I can get it to start (which takes many attempts).....sometimes it will run for a few minutes then die, without starting again until it rests a bit....but other times it will run well enough to drive it about ten feet....but without enough power to even pull itself up on the trailer so I can take it to the shop I purchased it from (they have a good reputation and I'm not concerned about them just putting a bandaid on it and sending me on my way).

It also idles high, around 1500, which I'm sure is just an idle screw problem.

While starting/trying to start it puts out white smoke, which I believe is unburned fuel?? Then once it fires up theres a small amount of black smoke, then it clears up. It will smoke again when turning the throttle up.

There doesn't appear to be any fuel leaking around the injectors.

Ideas? Major concerns?

I don't follow all of the Tractors and Loader and their capacity, but my Mahindra Max28, has a factory spec of approximately 1400 lbs. of lift on the FEL and I have trouble picking up some loads but when it comes to dirt, stone, or other loose materials, I find the FEL Bucket is not deep enough.
I have considered a used and/or new larger FEL Bucket but price is restrictive, and I am not sure what other changes may be needed.

I have started collecting some 1/4" Steel Plate from the local recycling yard, I am looking for 4 to 6 inches of width and in 60 inch lengths.
With these pieces of scrap steel, I will be adding approximately 4 to 6 inch to both sides of the FEL Bucket and approximately 6 to 8 inches on the top edge to reduce over spills.
I am not trying to increase the capacity, although I think it will allow for a better fill, I am more interested in stopping the spill overs.

So where am I going, maybe the OEM sized Bucket is the right size as long as you can add some more height to the sides and top edge !

A slight increase to the FEL pressure can off set the increased weight of both the added steel and the added fill in the bucket.

AND the price of the steel and the welding will be less than the a new larger FEL Bucket.

Just thinking out loud, sometimes too far outside of the box... LoL, hope it helps !

p.s. Have you added a fuel system cleaner ?

Have you used any starting fluid on it? Could be running on less than 3 cylinders. If you can get it running long enough to loosen the injector line slightly at the injector you can probably find out which cylinder or cylinders is not firing. Also see if you are getting fuel to that cylinder.

Could be the little sticker on your loader belongs to this company. They might not have manufactured it but rather just sold it. Inventory | Apple Farm Service Inc.

Yea I looked up that company, probably the case.

No, never used any starter fluid.....and the running on two cylinders thing sounds about right. I'll look into the injectors tomorrow.

Koyker Loader made in U.S.A

Also change your fuel filter, it sounds like water is is getting into the pump ect.

Thanks for the Koyker info.

Tomorrow I plan to check all fuel lines, filters, injectors, etc., starting at the tank and work my way to the injectors. Hopefully I can cure it before I have to take it to the shop and spend money I don't have.

 

[wmcelwee]

Well it turns out the fuel tank was stopped up. Took a pipe cleaner to the "drain" and bled the lines, running like a champ now.

However the alternator isn't charging the battery........unsure if I knocked something loose or it just crapped out.

Any help would be very appreciated, TIA.

If it was working prior to your checking out the fuel system, I suggest checking to be sure all electrical connection are solidly in place. These tractors are tight quarters to work on. Reaching under the tank may well have caused an already loose connection from vibration to lose contact.
Also if you checked injectors same process with the dyno.
2 places I would check first are the dyno and the regulator located on the firewall.

 

[wmcelwee]

Can anyone help me identify which model Koyker loader I have? Or should I contact them directly?

 

[kenmac]

hard to say, 140,or 150. Those folks at Koyker aren't a real friendly bunch to speak with.
They may assist you and they may not. Depends on what day and time you call
