Look up Sierra Park 730A web page. Most manuals including parts are listed. I'd guess the same parts are used on multiple models. That web page has been a great help for me. If no luck call Elvaan Equipment Solutions (formerly Jade). They have some new people and are pretty helpful.

I found there’s some aftermarket parts out there but unknown if cracked like this one was so got busy with cleaner and grinder and my hougen.

Just gotta cut the pin to proper height and cut a snap ring groove

Getting it close now. I hope this cold roll is tough enough.

I kind of doubt it would be anything special. To me it looks like graders are made with heavy thick components, nothing special except the moldboard which is 1050. If it doesn't work out you could make a pin from a hard chrome bar like a cylinder rod or even 1040 steel.

I've never seen that sheer off . It's mostly the other end that will break

I had the plate that you're working on break out around that stud on a series 4. I was able to weld it back up and its been holding since. Amazing the forces that get applied to various areas of these machines form time to time.

I was just thinking about Blue-Fox and here you are I drove past your yard a couple times last week. That was a cold son-of-a-gun on the K-Pen.

Never realized you two were near each other.

About a 5 hour winter drive from the MatSu, over Turnagain pass.

Yeah broke that SOB stud again. One on left was OE - guessing Chromoloy because my Hot Roll piece flexed a lot more before it failed. So here we are!!

This machine is a G970 with the 990 16’ tall tall mold board and I think that since the 990 has these mounted in double shear that’s what I’m fixing to do.

It was a hard winter. Besides that, how much other stuff broke this season?

When picking a new material for the pin and welding rod, look at the charpy impact numbers.

7018-1 has better low temp. impact values than standard 7018. I think the minimum requirement for 7018-1 is 20ft./lbs. at -40*. Std. 7018 is 20ft./lbs. at -20F. Something like 8018(C3) with 1% nickel would be a good choice as well with min. 20ft./lbs. at -40*.
