Not something you were ever planning on working hard, more of a toy, yes? Then yah, I think doing the easy(ish) stuff and calling it good sounds reasonable.

It's more of a toy..yes..it will never do any serious work that will rely on reliability to speak of.....it's not worth a new gear. If can come up with a inexpensive way to help it I will..
I'm thinking of finding shaft size bearings and making od collars to fit or steel rings with a bronze bushing. Either way won't cost much just time and make it little bit better

I suppose if you were still worried you could braze the worst pits and chips in the teeth...

I don't think the brazing material would withstand the pressure of the gear contact,even for recreational use.The teeth are probably induction hardened(or flame hardened back then)if you heat them to braze or weld you will change the temper.I've been down this repair road with old equipment and it's never easy to try to fix it on a budget.I had a noisy 1952 forklift transmission once,spent $400 on the LAST gearset available in America to try to repair it right-only to have just as much noise from it when I completed the repair.Frustrating.We have a lot of talented folks here at MBN with lots of experience;If you need advice not covered here at MBN,try the HeavyEquipmentForums.com -its free.

-Good ol Bob Nichols from Ontario(RIP-Mar'16)(Alaskan pipeline Cat mechanic)told me once-'spend a little money,fix a Cat right,it'l serve you well'

So think what I'm gonna do is find bearings close machine shaft to accept ID weather it's bigger or smaller (turn down or use a pressed sleeve) and make a rings to fit the housing to accept the smaller od.

As old as this machine is, its definitely inch bearings..I'd start with a Cat parts counter man..first question,whats the model and serial number of the machine.Serial number range even? year? Crossing over to metric some bearings come close at 107.95MM od, 50.8MM bore even those are $300/ea range..jobber/dealer at $198/ea.Are there any numbers visible at all on the old bearings?

I'm hesitant on the cat dealer....they are VERY inflated here...I stopped one time for hydraulic cylinder seals,I had piston and gland with me...guy took em;measured em...got out a book..clickity click on his super confuser and said 385 dollars and be here in two days...I said no thanks polity...when on down the road to the heavy truck shop Give him what I had...walked down row of parts bins grabbed what I needed. ..clickity click on computer and said 18 dollars. ....I'm trying to restore it just forcing it to work....although parts guy very gladly found a parts breakdown an faxed it me

Martin Gear has a part number S413 which is at least 4DP and 13T, 14-1/2 deg. pressure angle (which I am assuming the Cat is, as I think the 20" deg. Stuff came out later)...but it's only 2" wide, so even assuming you could attach two together, well, you still have to have two.

I couldn't find anyone who would actually say they have one in stock or for how much, though.

Boston Gear likely makes one also, but I haven't found a part number yet. I think the 4DP gears of theirs I have found so far were 2-1/2" wide...and too many teeth.

Thanks I had hell of a time looking I could fine 14 but no 13...I'm almost 98 percent sure it is a 14.5 degree gear. I is actually 2.600 wide....found one 118 bucks. ..not terrible price

It looks like in the 4dp stuff 14-1/2 is all anyone stocks anyway, so I think it is a pretty safe bet.
