Jinma 284 - rear axle gear

[oviv]

Hi,
I recently done maintenance on my Jinma 284 tractor and I change the gear oil in front axle and transmission.
My question is : do I have to change oil in rear axle gear or it is done within the transmission oil maintenance? The drain plug for transmission is under the tractor towards speed shifter, but I am not sure if this tractor model has a drain plug just for the rear axle gear... Any input on that topic?
Thank you in advance for your help.
Al

The mid-connect box, the transmission, and the rear differential all share the same gear oil. That said, each box has it's own drain. But you only put gear oil into one place on the top. That feeds both the tranny and the rear diff, and is supposed to feed the mid-connect. But that last part doesn't always work as advertised. Many remove the mid-connect cover plate the next day to top up what didn't pass forward from the tranny. Others have actually drilled and tapped for their own fill plug/dipsticks.

I did just this. Drilled a hole and tapped it then used a plug with a piece id 1/8" rod welded to it as a dip stick.
