I have a Attex 400 chief I am reworking the running gear on. So far, the front axles assemblies. Bearings are worn out and sprocket is thinnning out. I have new tbsuaki ansi 50 chain for front drive. what is the hot ticket for a good quality bearing and sprocket for this aatv? Any brands or part numbers would be great. |

I'm just going by memory but I think OEM is Fafnir RA100RRB. That number should point you in the right direction. |

I was thinking of installing the flange pillow block type in lieu of the flangettes. |

I've always thought that would be a better idea, at least for the outer bearings. The flangettes never hold up well enough to allow you to grease the bearings, and a pillow block may give you more support on the axle. Let us know if you find something that will work. They make a two-bolt pillow block that will fit on the inside bearing mounting holes, but I haven't tried them.
Good Luck. |

The cast iron flange is exactly what I have in mind for the outer bearing sets. The metal flangettes seem to have dubious abilities to allow grease infill thru the grease fittings. I believe that a wide range of commercial 4 bolt flange bearings will work for this application. For the inboard bearings there is a 2 bolt model that works exactly the same as the the one shown in the image. I am going to go with relubricatable bearings on inboard and outboard. Outboard due to the water that may get into the bearing from driving and inboard because I wash my inner tub down with a pressure washer. The so called "sealed bearings" are of questionable sealing capacity in the face of several thousand psi of pressure washer. Steve |

I found a good source for these bearings. If you search the bearing catalogs you will find the p/n for bearings with specific performance ratings. All the information is there to study. I would look for a good quality bearing of normal to medium duty that can be relubed to force out all the old gunk. Stay away from the cheap ones made in China. I have ordered the 4 bolt cast iron flange bearings for all 6 outer bearings. The inner bearing may be more difficult since it probably has to fit within the frame rails. For this application, I will take the tape and see how much space I have to deal with and then order something that will fit within the frame rails. The standard aatv bearings that I have encountered have been pretty miserable in terms of quality. Steve |

I am in the process of redoing my axles in my attex 225/hustler. I have the old style square ended axles and want a bolt type sprocket/axle connection like my front axle. Mine are originally 3/4". I wanting to go to 1 1/4" but cant find cast 4 bolt flange bearings with housing small enough to fit on my frame. It is only 3" tall. I already have the steel for 1 1/4" axles but might go 1" because of the bearing problem. I would really like to find the 3" 3 bolt circle bearings that are on it in the 1" or 1 1/4". I'll attach pictures.
I have been told they only used my axles first half of first year attex was in production. They are only in middle and rear and I broke 3 out of the 4 within 2hrs of my first driving time with it. At one point I drove it back as a 3x5. The fronts are 1" and bolt type connection from axle to sprocket and havent had any problems with them.
Steve, just curious, what size are your axles?
Larry

Larry- I thought mine was low performance........ My axles are 1.0" throughout. I have the axle tubes with welded on sprockets. The axle tubes bolt on to the individual axles with a throughbolt. Be sure to use the little washers that RC sells for this purpose. Use bolts with full shoulders thru the axles/tube/washer thickness. Link-Belt catalog 3000 has specs on all of their 2 and 4 bolt cast iron bearings. Go to Rexnord.com and drill down to link-belt bearing division. They have a round 4 bolt and a square 4 bolt bearing available. They also have a confined space 2 bolt bearing for tight places. It is just like the 4 bolt units except 2 less bolts and slightly less height. I am using the slim 2 bolts for all of my inner bearings. Check the catalog for specifications to see if the 4 bolt will fit. The 4 bolt can be used on the outsides as it will not have to fit between the frame rails. If the bolt pattern is more than your allowable height, you can probably rig a flange plate so that all 4 bolts can be secured. On the other hand, you might consider using the 2 bolt in all locations. Try the Fafnir VCJT-1" and use it throughout. For axles, if you have 3/4" you are probably having all kind of trouble. There is a guy on Ebay that sells 4140 steel cut to size for axle shafts.
I have some 1.25 cold rolled max II axles that I could use, but I am going to stay with 1" and use 440 ss axles as needed. Since I formerly had the old balloon tires and am now using regular rims, I will be sawing off an inch or two from the outside dimension of the axles to provide less bending moment at the axle.
You can use a 1" 4140 or 440 shaft and pick up 3 or 4 times the strength against bending. As for sprockets, I am undecided on using weld on or using taper lock fittings. |
