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.
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)
