Welding Heat Treated Cast Steel Gear

My thoughts were if you weld and machine for living you would know how to fix it ((20 years ago I could take this to any welder/ machine shop and never be turned away)). I know it would be a welded up gear with no guarantee but heck you think someone who does this all day would have a better shot at making it stick than a guy who does other things with his hands.

Seems now a days nobody wants to fix things, just replace components. When was the last time someone trouble shooted a repair before just replacing parts?

I guess I am old school , I try to fix it if I can and save people some money. The gear is obsolete and finding older internal uncommon tractor parts is getting hard. This part was in JD A,60,and 620/630 and most of the guys I deal with did not have it or it was damaged.

So what are the choices dont repair, weld it or charge more than the tractors worth?

I've been doing this for 35 years, and there has been some hard lessons learned along the way. For the reasons others have stated, I wouldn't try this repair for a customer, unless he fully accepted the risk of a failure that might destroy other gears, shafts, the transmission case, etc. And, believe me, we resurrect all kinds of iron that by rights should go to the recycler. I would find it hard to believe that a gear for that tractor can't be found. They made a ton of those tractors. Have you asked over at Yesterdays Tractors? I'd be surprised if they can't steer you to one.

If it is cast steel, I've seen gears built up with weld then the tooth shape recut. If it is spiral cut this is alot harder to do but can be done. There are places that make custom gears though, especially if it just has a plain bore, ie no big body.

Found a gear that is compltete, maybe I will buy a tig welder and make an oven and add another shingle to hang under the sign. Who knows another ten years everyone will have to fabricate the parts for the old stuff or fix the broken parts

Sir: Still wondering what model Deere this is for and what is the part #? I offered to find you a gear. No way you can repair it or make one cheaper than buying used. Used Two Cylinder Deere gears are not expensive, there are tons of them being scraped. Which gear is it?

I have already purchased a third (times a charm) replacement gear that was usable, it is part number A3810R The shiny/glare is the broken teeth/portions the other gear is rusted up but intact

This is what it goes in JD 60, pictures from last spring after I got it running and before it was stickered up and final painted. I plowed, mowed, disked, cultivated/hilled all last summer and towards the end of the season I would hear a howl for a brief second when it was under power, this spring I took my youngest for a ride and it was more noticeable. The tractor has a two piece upper transmission shaft with a light weight bearing that was starting to become worn out.
