Need Release Gear

[Jw5875]

I need a release gear for a 5 ton hydraulic floor jack, this is the concave one that is on the valve on the jack (12 Tooth).
Any ideas etc. to find one?

Thanks,

Just saying it's a 5 ton jack tells me that it is a chinese made jack, not an "older repairable" USA one...Pix??.

Finding parts for these is not easy, is the gear stripped from over-tightening (probably from internal creep-down)??.....If so, then time to buy new jack
