Loader Un-findable Part Need your help

[lfrie]

Gentlemen, I am looking for parts to repair my Jinma 224 (Hercules 2224) tractors hydraulic pumps. It has the ty290x engine (two-cylinder diesel) but uses an unusual twin pump hydraulic system setup. One pump operates the power steering (upper pump) and the other the FEL and rear lift (lower pump). I have attached a diagram and parts list of my system and pictures of the failed parts.

Basically what happened is a bearing went during operation and took out the gears. No problem all i need to do is replace the gears right? Wrong!! While the gear/shaft/pump driver is readily available the gear (with bore) is not available ANYWHERE. Phil at Circle G has tried as have many others to find the gear and no one seems to recognize the setup.

I have looked into having the gear made but at $2800 it does not make since. Has anyone seen this setup before? Do you know where I might find this gear? I know I can reroute the hydraulics and convert it to a single pump setup but i would like to keep it as designed.

I have listed the part numbers involved and description of what I need.

Idle Gear Jinma Part # TY290X.02.184 (the gear I am looking for)
This gear is a Left Helical gear with 24 teeth, a keyed ID estimated at about 15/16th , OD estimated at 2 5/8th (2.61?, thickness of 5/8th (.62?

Hydraulic Pump Gear Jinma Part # TY290X.02.121-1
This integrated gear-shaft mates to the gear i need and is a Right Helical gear with 24 teeth, similar dimensions to the idle gear listed above​

Any Suggestions would be greatly appreciated.

Tractor background:
2000 Hercules 2224 (private labeled Jinma 224)
232 hours
Purchased from a little old man that only drove it on Sundays (but left it outside its entire life).
Even with the hydraulic issues I think it was worth the $900.00 price (but i may be proven wrong)

Well, I think the problem is that you're trying to buy Jinma parts for a Benye/Rhino. Try Farm Boys in Tennessee. If they encounter the same "unfindable" issue, I'd say the most reasonable alternative is to simply buy the conventional TY-290 drive gear assembly. Then reconfigure your pumps in series. That is, right now you've got pump-drive-pump. The conventional config is drive-pump-pump. Only problem I could foresee is if that puts pump #2 too close to the starter motor wiring.

Are you sure that is not a Jinma Greg? You would know better than me but it sure looks like a older Jinma with side steering to me. Granted, I have not seen many 224, only 254 and up.

$900 was a steal. The loader is worth twice that alone.

You are not going to find this gear, unless you can find a cannablized TY290 engine.I have 3-4 new TY290 Engines in the crate but all were set up for the single pump.I have the dual pump pump driver but not the gear you need.

The TY290 engine was made at a prision in China which has long been closed down, you are going to have to convert this to a single pump system

Now there's a cool piece of trivia !. Are you recommending single pump because of starter motor interference? I kinda suspected the two cylinder might not have sufficient front to rear clearance for a pair of pumps in series.

I am planning to convert to a single pump if I can't find the gear. I thought I could swap the E310 pump in place of the E306 and run all hydraulics from the E310. i have a diverter valve and just need hoses routed. Shouldn't that work?

Hercules 2224 with Farm King 95 loader, also marketed as Rhino 224 with Allied 95 loader. Tractor by Benye, loader by Buhler. Since it was purchased used in Oregon, I suspect it may originally have been sold by Rhino/Mark Leonard (now TytanInternational) up in Washington State

Boy, they all look so close. The good, drivers station, ect look just like my Jinma 284.

You could, or you may want to upgrade the pump to a CBN-E314L pump,reroute some hoses to the diverter valve.While the tractor may be a Hercules the TY290X engine is the same as the one used in the Jinma Tractors,and many others

If you're going to go to a single pump system, I'd certainly recommend doing as Tommy suggests and upgrading to the CBN-E314L pump. It will have about 40% more flow than the 310 pump and Chinese tractors are known for being a bit shy on hydraulic flow in most cases. You'll find that your loader will operate much more smoothly and even be capable of compound moves with a higher flow pump. I planning to upgrade the hydraulic pump on my 304 Jinma to a CBN-E320L in the future for just this reason.

Greg,

Thanks for the feedback but everything I have on this tractor points to Jinma. I am the second owner and have all the paper work that came with the tractor (operators manual, Parts Manual) and it says Jinma. I am unable to find a Benye/Rhino parts manual for reference. Do you know of a sure way to tell? I contacted the Rhino guys out of TN and the think it is a Jinma as well.

I thought it was a great deal, until I started looking for a simple gear.

 

[greg_g]

Unless somebody jokingly attached Hercules 2224 decals to the thing, it's a Benye. But as Chris intimated, sometimes its hard to tell simply from outward appearances - especially down there in the 18-28hp size range. As far as the manuals, I don't doubt the original MY2000 year manuals got lost along the way. You'd be amazed at how many folks buy used Chinese tractors, then come here for help cuz they didn't get manuals with them. A previous owner could have erringly picked them up on eBay.

That said, you might contact Tytan up in Kalona for a 2nd opinion

I think my tractor could be a Rhino/Benye. I have found ONE picture (2005 Not Listed 2224-4 at Agri-Service Inc., Twin Falls, ID on Farm Equipment Center: Used farm tractors, farm machinery, and implements) of a 2005 Rhino 2224 for sale in Idaho. If you look at the right side you will see that it uses the same hydraulic setup as my Tractor.

Where do I find Parts, correct Manuals, Dead tractors (for parts)...

 

[greg_g]

There may be others, but there's not reason not to start with the already mentioned Farm Boys or Tytan.

Has it been established that the engine is a Jaing Dong TY 295?
If this is indeed the case then it is possible that the TY 290 and TY 395 share the same accessory drive housing which allows two hydraulic pumps to be mounted on it, one in back adjacent to the starter and one in front adjacent to the radiator. Would this be something worth investigating further?

The engine is a two cylinder TY290. I have attached a picture of the only other tractor I have found with the same setup as mine. It is a 2004 Rhino. Notice the pumps are offset. This is because of a clearance issue with the alternator. If anyone knows where i can find a setup like this in a salvage yard let me know. Tom at farm boys is working on it as well. I have already stumped Phil at Circle G (which is HARD to do).

The fact that it is a two cylinder engine is irrelevant in this case. In this picture I see the main hydraulic pump is mounted offset to clear the starter. The other pump is mounted in front. Do you have the second pump mounted in front? I believe there might be another place on the left front of the engine where you can mount a pump.

Pretty sure that's already occupied by the injection pump
