Grader blade pivot bolt

rpneal44 · Sep 2, 2021

I need a part for my grader blade that is not available any more. (not for a long time!) it's the pivot bolt that allows it to turn or angle right-to-left. I need a bolt that is 3" - 3-1/2" long and 1-7/8" in diameter to replace it. I guess 1-3/4" dia would work. A couple of appropriate size washers and a nut would be nice too! If anyone could point me in SOME direction for this, it would be appreciated. The blade is a BushHog model 1123.

McMaster-Carr has 1.75 dia bolts.

I believe you will have trouble finding 1-7/8' diameter bolts. 1-3/4" and 2" are the standard size diameters. You can find those, as well as nuts and washers, at McMaster Carr in several grades. You may have to purchase one longer than you want and cut it off if needed.

A machine shop should be able to make what you need.

How about a 48 MM bolt (1.88), McMaster Carr has socket socket head cap screws that size.

1.889 might work, might be to tight.

Reaming the hole to 1.900 or 1.905 would be the premium option. A small engine straight hone would also work. The hardness of the cap screw would be a real asset to the pivot. Creating a grease fitting to it would also be desirable if missing now. Jim

Could you use a heavy bushing in there with a smaller bolt, so the bushing would take the abuse?? Just a thought as that's what I want to do with mine.

I would use the biggest bolt you can find that goes in and use a bushing or make a bushing to fill
the gap.
I have made bushings smaller by spinning them in a drill press with bushings and a bolt in the
chuck. Use sand paper or file.

Here is one I made last winter. I turned a piece of shaft to fit the holes, then threaded it to fit
the largest nut I could find in my junk collection. Welded a piece of plate on for a head.

Any machine shop or backyard machinist should be able to do this.

Hope the picture will load

ICloud photo. Can't make photo load. Downloaded it twice to my computer, can't find it in my files.

Can't even find ICloud downloads directory in my files.

Giving up.
