Can anyone tell me what the pressure at the pump "ought" to be? The manual gives no help.
The cylinder is (I believe) the original furrowing cylinder for this machine--its externals and internals match perfectly the parts blow up I have. Does that type of ram even have an air hole to bleed in air somewhere? I can"t see where... I understand the concept on a 2way ram that's modified for single action, but I thought with this thing, fluid comes in and pushes the ram out, when the ram returns it displaces the fluid back out the line... so there really isn't an internal place for air to fill and bleed from. Is that wrong? These little G"s are the only 1 way hydraulics I"ve ever worked on, and it"s never been an issue. Does anyone know where such a hole ought to be? I suppose if I had plugged it, or some piece of crud is in there, it could be the culprit here.
There is no oil leaking out the packing. I thought maybe just the stiction of the new, tight packing would put it over the edge so it can"t lift, but if I manually lift up the furrowing bar to help it out (with the lever in the lift/up position), it can"t even hold it up there. Makes me wonder about the air hole issue. So:
1. Where is the air bleed on the OEM rear cylinder? 2. What should pump pressure be?

The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
