    This is the second western pro 3 spring 8 foot this season that broke in the same place. Has anyone had this happin before? It seems to me this a weak spot on these. Please give advice how to fix. I'm sure I can weld back together. Both pistons now are extended forward. How do I push them back?

    Pics are worth a thousand words.

    There has to be some slack (tolerance) in the mating parts.

    The sleeves are a notorious weakspot on the ultras. This is doubly true if you purchased it in a weakened (split, rusted, torn, etc.) and proper repairs are never made. The proper repair is to cut out the sleeve (circle as you call it) and weld on a new one. You can purchase a new pin if you need to, and fabricate the sleeve yourself if you have a welder.

    One more question. Both pistons that angle the plow are fully extended. What's the best and safest way to push them back?

    loosen up on the hoses will let the pressure out. Then just push em in,

    you mention it is a 3 spring western pro plow. western hasn't made a 3 spring pro in about 15 years. not surprising that after 15 plus years the plow would fail at the pivot point (I'm guessing when you say center pin you mean the pin the blade pivots on?). as mentioned, pics would help.

    they are easily repaired with a welder and some fabricating skills.

    If I'm going to bleed the hydraulic fluid out of the pistons do I disconnect the line at the piston or at the pump?

    Easier if you disconnect it at the pump, then you can put the hose somewhere to catch the fluid. Unless you don't care about spilling all the fluid on the ground.

    Also, if there's some contamination in the rams, you can flush by putting cleaner or ATF in a container and submerging the ram hose in it while extending that ram...the other ram will be ejecting fluid out at this time (because you are compressing it). Vice versa on the compression stroke. A few times on each ram will flush the rams if need be.

    I unhooked the pistons and the plow came off. Seems to me a lot of weight to put on that one bolt .

    The weight isn't really on the bolt but that's where it pivots and wears out.
