    I would venture to say tip to tip should be four inches

    You want some play, how much slop do you have?
    Are you sure it's not from the pivot bolt?

    From the pins in the holes.total? Might be a tad excessive. But without seeing it it's hard to say. Remember you want some movement in the pins. There not.supposed to be a press fit

    Yes I know the pins. Unless you get a video up, or really detailed pics no way to say yes or no. However if you feel it's time much then replace the pins. Do you have the grease fittings in the pivot bar?

    I would venture to say that 4 inches tip to tip won't let you get any sloppy again!! Lmao!! Sorry Pat couldn't help myself

    Old plows get sloppier with age. Better than seizing. If you are concerned you can replace the swivel bar and the pins to make it like new again. As said above its really a judgment call.

    I bought a 10 yr old county lot truck. It only had 16k miles over ten years and other than runs to the salt bin and what ever time spent applying salt, they were all plow miles. The place I picked it up was 1/2 mile from a Western dealer and since I had no clue what was acceptable, I stopped in. The owner looked everything over and pointed out a few things. He said 3-4" inches of verticle play was OK for the age, he likes to see 1-2". I am a machinist and have a full shop at my home. I'm going to make and install an Oilite bushing this summer since it seems to be getting a bit more loose. The other thing to look at is the weld around the horizontal, center bolt that joins the subframe to A frame (I'm sure my terminology is wrong). Mine needed welded. That was the only thing I had to do besides touch up some rust spots.

    Read through the thread. Great tutorial. I wish I had the patience to do step by step stuff like that. I usually think about it half way through. I've been wanting to do an 80% AR lower tutorial for a few years. While I've finished several, pics or video just haven't happened.

    On mine? The guy had me raise the plow, he put a tape on the ground at the end of the cutting edge and pushed up and down. He was measuring the vertical travel of the cutting edge.

    So did he lock the pivot bar then?

    I don't think so, all I did was what I described above. He was standing at the end of the plow. He did nothing near the center.

    I just did a quick Google. I see what you mean and he did say there was 4" of play before what is called the pivot bar moved. I didn't know what it was called until now.

    Without knowing which style of ultramount, and approx year I can't say. However how do you know it's not the center bolt on the aframe?
    There was talk about the pins awhile ago, and as was already said, you want play in them. And if the pivot bar doesn't have the grease fittings add them.

    I guess I need a nomenclature lesson. I think my issue is the main A frame bolt. My plow was bought and installed when the county bought the truck in 2006. It is a 7.5' straight plow with an Ultra Mount. I have all service records and date of in service stuff. The Job and Family Services Dept gets a grant every 10 yrs and they buy a truck and plow just for their lot. Gov efficiency at its finest.

    The lady in charge of disposal of surplus equipment was also the road Dept manager. She didn't understand why JFS didn't have the existing county trucks clear their lot. It worked out for me in this case though.
