Pull the pins, and the inner bearing does have set screws. I have only seen one machine that actually used them though, most of the time the axle is just sitting in the bearing. The outer bearing is press fit on the axle. The sprocket tubes can get rusty and really stuck on the axle even when the pins are out. That is probably going to be your biggest obstacle. If you have a slide hammer you can attache it to the axle and put something inside so the sprocket tube isnt damaging anything and hammer away is best bet. You dont have the option but normally easiest way is to take the pins out and drive it around untile the sprockets break free.

The upper and lower body halves have the rubber body band stapled on and the halves are riveted. You dont need to take it apart though. You can pull the frame and stuff out with taking it apart. But it is a lot easier to work on stuff if you do.

Ok thanks. That helps.


The 7000 is the better atv manufacturing (baker hill)model transmission. Another plus+++ for you.

Once we get the frame out I wanted to take the body halves apart to repair the plastic. Thinking of getting a plastic welder from HF to fix it. Is ABS like fiberglass where you drill the end of the cracks before affecting repaires to prevent further cracking? Besides I dont like the exploding rivets they used. I would just use large head 3/16 rivets with back up washers like on the race car.

Im not sure if the cracks are the same but I would think so.

Maybe you should check out the Angle Iron Body Band for when you put it back together.

Can I use lawn tractor rims and tires as a cheap way to get it rolling? Seams very similar to a lawn tractor I worked on. back out to work on it.

[LarryW]

Cheap rims would be golf cart 4 lug 4" bolt circle. There easy to find used thanks to golf carts and there owners swapping for bigger aluminum wheel. The rims are also cheap new at tractor supply and such. For the tires lawnmower style would work good for a cruizer or testing if you have some laying around but it wont do well at all off road or in water of coarse. If your buying new ones might as well get some that will work good.

[birddog1148]

Well frame is out, needs all new bearings, new chain rear frame crossmember and inside rails front to back.
As far as tires, if I can get it going on used ones thats ok. Did I mention that I have an AWSOME tire grooving machine? One of the ones that is adjustable impulse style so heat is instant only when grooving.

Would this work as an outer bearing?
McMaster-Carr
If not where do I get the outers?

[LarryW]

Best bet is to use your own flanges if there good. Its hard to see what bearing style you have there are a few. Some bearing inserts are radial outside edge and the other style has internernal snap ring. Take one out and measure the inside outside and width and shop around. Jeffpswift1 found a place I havent tried yet called buffalo bearing. I have heard multiple members say how happy they where with a good quality bearing at a great price.

Partial quote from a post with Jpswift1 "Call Buffalo Bearing and tell them Jeff with the 6 wheelers sent you and they'll take good care of you. You can reach them at (716) 874-1720."

LarryW is the man when it comes to knowledge about first generation Attexes, so if you listen to his advice you won't go wrong. I believe there were 3 different axle diameters used in the first generation machines. The early 208TT had a 3/4" axle, and then some models had 7/8" axles and some had 1" axles. As Larry said, take some calipers and measure the axle diameter and let us know what you find out. I might be able to get some part numbers from the bearings that I got for my first generation Attex racer.

[birddog1148]

Axles are 1 in outer bearings have rx268 on outside of flanges.
Thanks

If you call the guys at Buffalo Bearing and give them that information, they'll certainly be able to cross reference the part numbers and hook you up with some good bearings at a good price. Ask them if you can get a tripple or at least double lip seal on those bearings as well. With tripple or double lip sealed bearings you'll have longer bearing life.

[LarryW]

My early 3/4" axles are 3/4" in inside and 7/8" outside. The 1" axles are 1" inside and 25mm outside. So make sure you measure where the bearing is and not just the shaft.

[birddog1148]

Larry, I measured where the axle goes in the bearing and sent Buffalo Bearing an email. Thanks!
