Wood splitter hydraulic adjustment

[Bucksaw]

 

 Is anyone familiar with adjusting this hydraulic control on my splitter?
The pump is mounted inside the tank and driven by a belt/pulley.

Look up who made valve and the number then Google it .

What are you trying to adjust?

No numbers visible and it is probably 40 years old. 
Trying to increase pressure/force.

Well im not seeing a relief valve in that picture.  I might be wrong byt think your picture is of tge backcap covering the automatic retract kickout valving.  I wont be surprised if the relief valve you are after is integrated inside the pump.  I dont know what the standard was that long ago.


For safety you ought to have a pressure gauge and not turn it up beyond tge hose rating.  Fluid injections often end in amputation.

This is a Williams belt driven internal pump that we have on our ox bow sweet corn harvester.The Re͏l͏ief valves are inside the reservoir on the pump .
I am not sure this is what you have but it could be similar

Very likely a Williams pump or something similar. I'll take it out this winter. Thanks for the help.
