PC1800 Front Shovel (1/12)

[DADSGARAGE]

Did some more "high tech" testing of the hydraulics....turns out it does work but not as planned...lol...the open center valve is not the best for running more than one function at a time, live and learn, need to convert it to a closed center which will mean the PRV will be bypassing all the time when the controls are in neutral instead of free flow back to tank when using an open center valve.

Started testing with 20 lbs and then added another 20lbs to see what it would do with the 40 lbs....the extra weight made little to no change in cycle times or pressure

After running it with the 40lbs I noticed the 1/4" threaded rod was bending under the load, so went back to using only 20lbs for the "wire and wood" testing...lol

The motor and belt drive seems to work well, using a small adjustable pulley on the pump so the RPM of the pump can be changed a bit while using the same input RPM of the motor
