Ben,Not sure if we are communicating, so let’s try again. I have the Jinma 284 with a JW03 Chinese backhoe.
A is the PTO shaft that is not used for this backhoe.
B is the 4-bolt cover which covers a slotted shaft for the Auxiliary PTO.
C is the CBN-E3 pump which attached in place of the 4-bolt cover and into the slotted shaft.

Ben,
If it helps you, here is a picture of the back of my Jinma284.
The darker rectangle plate with 4 bolts directly the covered PTO shaft is the cover for access to the auxiliary PTO connection that Bob Rooks mentioned. My JW03 backhoe connected here rather than on the PTO shaft and I believe that most of the Chinese backhoes did.

Tin,
Are you really telling me that in order to send a simple PM to another member on this 'new' site, it is necessary to go through the “social network” garbage?

Steve,
I'd be interested in the schematic, etc – but I no longer know how to PM you since this site has changed.

Here is a picture of the swing
spool assembly on my JW03 backhoe if that helps you.RonJ

The first thing that I would do is to install a pressure gauge between the pump and the FEL valve to see what is going on.

I would recomment the Ansung BH760.
I recently put a BH660 on my Jinma 284 and can't say enough about it.

Guess that I am confused by these last 2 posts.
If you can add a section to the Backhoe control valve to work the thumb, why use Power Beyond capability?
