I imagine you've already scoured the CootWorld classifieds for parts, so a second option might be to try and get in touch with forum member Coop, who used to have some parts laying around.

Yes and thanks for the advise
If you are near a Boston Gear dealer a lot of what was used by mfrs may be theirs, if available. The no longer available Apex gear was.
their website does show alot of pictures of gears that look alot like yours.... good luck in finding one, j.b.
Thanks for the heads up I'll give them a try
I think you should contact forum member Whipper, he has a machine shop in Arizona and should be able to fabricate a gear for you. It may cost a bit more than something that you buy off the shelf, but he does fine work and the gear should outlast the Coot. He will no doubt need you to send him the original so he can spec it out.
get this thing going so we can ride again!!!!! The argo is missing pulling that coot out of the mud :p
Yea I hear you Castro, I'm having withdrawals to. You’d think in this day and age anything could be had but I’m jumping through hoops and not getting anywhere. I don’t understand how a transmission this heavily produced (All Coots, Eagles, Terra Jets and a number of 6wheelers) for over 30 years and NO ONE kept manufacturing or has a stock pile of this common gear and NO shop can make it so far for under $900!
BostonGear got back to me after I sent the model and drawing:
“Thank you for your drawing. Unfortunately, we do not have a standard gear that could be altered to match your requirements. We would not be able to made a custom gear for your low 1-2pc quantity. However, thank you for your opportunity and have a nice day.”
I'll try and get a hold of him Noel thanks.
Allwheel if Whipper can't help you I have a suggestion. Find a very competent welding/machine shop. With the proper technique and proper high strength filler material, it looks like that gear can be put back together (although I don't like that tooth in the keyway). Finding a new gear, or having one fabricated at a reasonable cost is ideal, but as a last resort the welding route will at least it will get you going.
Have ya tried these folks?
Replacement Parts
I tried them 1 month ago. They said they will not, and can not make any gears that could be used in any sort of vehicle, on road, off road, or sport, anything with wheels. They said it voids their insurance.Quote:

That is pretty lame. If that held true for all parts suppliers, no one would be making or selling anything, for fear it might be used in a way that might bring them into an alleged lawsuit!Quote:

I have found a good deal of 12 tooth gears with very similar dimensions (but not quite), but it seems the 13 tooth is completely non existent in anyone's line up period )-:
Still waiting to hear back from Whipper-AG I sent him a PM and an email no response as of yet.
I'm going to stay away from welding it back together. These gears are notoriously frail, if they shatter when completely fresh and in good shape I doubt any weld will hold. Not to mention the fact the weld would have to fit in the keyway somehow.
It is rather frustrating. I recall spending months trying to figure out what was wrong with my Predator 460 only to have a Predator dealer look at it and tell me he couldn't figure it out either, I bought a new one and moved on. The fact I can't just "buy" a solution (for less than a considerable portion of the machines worth) is very aggravating to say the least combined with the fact this isn't like trying to find spare parts for a Quadractor or a Pengor Penguin. This tranimssion was in mass production for decades. Somewhere a box of thousands of these gears are just collecting dust.
allwheel, i agree .... that gear is sitting somewhere in a box or on a shelf... how to track it down ? could it have been used in some other kind of machinery ,etc. also ? i wish i could suggest a place to advertise a wanted notice. keep at it though, it will appear. j.b.
did you try a co. called rushgears.com ? says they will make 1 or 100 of type needed. good luck, johnboy va.
Allwheel, maybe you have already seen this, but maybe you should just start emailing some of these folks and see if they have any spare parts.
Brendaa@nemaine
PM sent.
I can make that gear.
I'm the opposite of all the other shops,
I only make stuff for fast cars,on road, off-road.
The only vehicle I wont make parts for is a Mudd-Ox:rofl::rofl:
Whipper :spider::godzilla::scorpion::6x6burnout:
Please help allwheeldrive out, I am itching for some serious action in the mud and woods and he currently is the only one around me that I have had the pleasure to ride with. I had serious plans about using the bigfoot to tow that damn coot out of some more mud holes and im getting plain tired of waiting :p
I really appreciate all the help and suggestion guys!
I contacted Whipper, light at the end of the tunnel at last!
Got my new 1st gears on Friday. Super high quality. Figured I’d update the thread since I hate finding year old threads on other forms with no conclusions.
Pictured new vs old and installed. You can see how I have changed the design to be much more beefy. I took the risk of increasing the wall thickness of the collars (Plus adding a 2nd). I measured with shims how much room I had to work with and split the difference for a few thousands of clearance. Everything seemed to run smoothly but once I installed the roll pin the gear lost what clearance it had and meshed with the big 1st gear when in 2nd as can be seen in the zoomed in photo. I sanded some material away but it seems like it’s more a function of slop in the entire transmission that’s doing it more than anything as the same teeth and spot never rubs twice. The gears still spin easily by hand so I reassembled it and put the Coot back together. Granted in 2nd I get an audible chatter as 1st walks or clips the collar of 1st pinion (the replaced gear) when in 2nd from the lack of clearance. Everything runs nice and shifts smoothly. It’s annoying to image that inside the transmission 2 gears are clashing and making a racket but I’ll leave them be and just wait for one to wear the other until they miss or get quieter as I figure I can either remove material until they stop clashing or just wait till they do it on their own.
Any thoughts?

nice job on the new gears !! was it whipper that did make them ? what oil goes in the trans ? maybe there is a '' slick '' type additive to help the meshing. seems like they will eventually wear down like you say and the chatter will decrease. change the oil after a while and see if there are any filings. good luck, johnboy va.
If your plan is to let them self wear, stick some heavy duty magnets to the outside of the case so all the debris will stick and not be wearing other parts
Yes Whipper made these. Standard "gear oil" 90 weight I think it was whatever the Coot was spec'ed to run in the transmission. Just my plan Racerone3 I have a big neodymium magnet I used to retain the seatbelts under there now, will replace with 16 large neodymium hard drive magnets when they come in the mail.
