Need help finding scarifer wedges.

I have a 1954 CAT-12 grader and I'm short a few scarifer wedges. The part number off the wedge is 1D3537. This part number crosses to a Tee looking piece that is non-compatible. Obviously CAT changed the design, but why recycle the part number and apply it to a non-compatible/different part? Does anyone know if the old style wedges can still be purchased? There's a casting seam on them. Presumably cast steel (they don't break when you smack them hard with a hammer)? It would be tedious to machine these from bar-stock (my last resort option). These wedges are old. They fit the Cat12 and also the previous CAT Auto Patrol Graders. Please help?

would that be a 8t serial number?

Yes. My machine is an 8T serial number. But the scarifier assembly I purchased came off a CAT 112.

Of the old info rolling around in my head seem to me they changed the shanks to ones that had notches in them that the new wedge you got fits that was in the 70s I think finding a new one is going to be tuff maybe check for parting out machines

At least you can still by aftermarket/replacement shanks & teeth, but apparently no wedges. . . . .

When I purchased my CAT12, the scarifier assembly was missing. I recently got one off a CAT112, which is the lighter-duty version of the CAT-12 (with the D315 engine). The scarifier came with a few extra scarifer shanks. One was broken in half, and two others were bent. I was a bit surprised by this. I assumed the machine would stall before bending/breaking a scarifer shank. Another individual recently told me to keep my front window open when grading - so I don't smack my face hooking a large rock.

Yes and watch your wrists I can remember a guy was trying to adj. alot of play out of the circle He had me running machine levers were beating my wrists so bad I started using my foot bad plan it shook my foot off and thru the window it went

Frozen ground, going too fast big rocks. Been there done that. Rear mount is better for the heavy work

We live in a neighborhood of 5-acre lots. We've got about 4.5 miles of private roads to maintain. We spend about 6 grand per year paying a guy with a small finishing grader to fix our roads. He has no scarifier, and his machine is too light to cut/fix the crown on the road. I think it's a 12,000 pound machine? He basically uses his grader as a rake to spread out crushed-rock deliveries from dump trucks. He also recuts the drainage on the sides of the roads in the most irritating way - he narrows the road a bit every time - pushing good rock into the woods. Our roads are crushed-bassalt rock (1-1/4" minus). I'm hoping the CAT12 will be able to handle this level of work. Our roads are well-established. There shouldn't be any big rocks to hit with scarifer (fingers crossed). I just need to loosen up the surface when needed to fix the crown. We have very bad pothole problems where the road is flat - people constantly filling potholes with their private tractors & backhoes. Half our road dues is spent on crappy grading service, and the rest on purchasing crushed rock. Our road association bylaws prohibit paying anyone living in the neighborhood to do road work (keeps things honest). The best we can do is compensate people for their fuel whenever private machinery is used. Thus I'm basically fixing our roads for free.

There is a member on here with a YouTube page graderman 140m. He may have tips in his videos. He does county road maintenance. All I csn tell you is that filling potholes never works, they alway come back. That is where your scarifier would be handy. Dampness is your friend. No standing water but maybe an early morning shower. Use the grader wheels to compact the material when you are done grading
