Posthole Digger Danuser Model 8300-1 & 8300-2 motors

[fisherridge]

I bought what was thought to be a Danuser model 8300-1 hydraulic post hole digger from a tractor dealer. The 8300-1 is for hydraulic flow rates of 5-10 gpm.
After I got it home I was inspecting it and found the serial number tag that identified it as a model 8300-2 that is for hydraulic flow rates of 10-20 gpm. My machine only has a flow rate of 8.7 gpm.
Because it was old stock, I got it at about half price. And since the only difference between the two models is the motor, I want to keep the digger and just change out the motor.
Danuser will not tell me what the Char-Lynn product number is for the 8300-1.
The product number for this 8300-2 is 104 1005 006.
Anybody have a Danuser 8300-1? Could you please take a moment and look at the end of the motor and tell me what the product number is.
thanks

Thanks, ddaacc.
Don't go to any trouble, I'm in no big rush.

Fisherridge, Attached are a couple of photos of the motor. As I understand it, if you swap down, you will get more speed but less torque. If this is what you want, might you be interested in a swap? my unit has deilled in 16 fence posts since it was brand new but my soil is rocky and the torque is of interest to me.

Sorry, this is the one without the flash.

ddaacc,
Thanks for the information.
I may be interested in a trade.
I knew my unit was old stock when I got it but I didn't know exactly how old.
The dealer just said he had had it for a while.
It turns out that it left the Danuser factory in 1993.
The code on the motor indicates that it was manufactured in late 1992.
So I need to hook it up first and see if it even works.
I'll definitely let you know.

Thanks again,
fisherridge
