I really need to get to a Western Dealer and pick-up a mechanic's manual but, 'till then I thought maybe someone here could help me out. There are several adjustments on the Western solenoid controlled unit that I need some help with. #1 There appears to be an adjustable plug/valve on the top of the actual hydro pump itself (in the resevoir). Is this the pressure relief valve? If so, what will tightening or losening do? #2 There is a valve/adjustment on the valve body located on the same side as all of the solenoid controlled valves. There's a spring, a stopper and a ball bearing in the hole that this valve seats in. Is this the cushion valve? It seems to control the flow/pressure of fluid to the angle cylinders. Loose = less flow / tight = more flow. Right? #3 There appears to be a similar (set screw type - like the quill only bigger) valve/adjustment on the front facing of the valve body. I wasn't able to break it free yet but - what is it? The poppet check valve? If so what does it do and how do I adjust it. My whole reason for inquiry is that I'm trying to get the plow to move faster from side to side. Right now it takes about 3 seconds to go from full angle right to full angle left and about 4 seconds to do the opposite. There's a brand new electrical motor and a fairly new pump in it. Flushing the system and changing an angle cylinder really helped improve plow performance. Also, replacing an o-ring on what I think is the cushion valve and losening this seemed to work too. Any insight as to exactly what these valves are, how they affect performance and how they can be adjusted is greatly appreciated. As well, any other suggestions on how to angle faster? (or maybe this is fast enough - we only have one other western and it's brand new so it works like a charm. This unit is probably 6-7 years old). Thanks - any help is much appreciated!
