center axel

[garretttpe]

I All
I am trying to remove all my axels (2000 MAX II)and all I have left is my center ones. I do not see any set screws or any other type of retainer clips on the triple sprocket assy on the axel. I was able to release the axel form the inner bearing retainer but the triple sprocket assy will not budge. the axels are not corroded.

Please can any one give me some advice on how to remove it?
Thanks
Larry

Scrape the sides clean to the axle and check for a snapring. 2000 has a chance of being a very early snapring axle. I've seen the center with a springs and the corners screwed. If not scrape hard between the sprockets for a setscrew. There's something lust not sure what holding the axles.

msa, i have a 2000 max 2 and just removed the center axle triple sprocket. mine had a top set screw then another one under that. not sure yours is the same.clean it well, sometimes they are hard to see. hope this helps. john boy va.

Hi John
I found it after cleaning it real good. it appears that some one has ground the set screw flush. and drilling it out is not going very well at the moment. If all goes well I will have it drilled or cut it out tomorrow. the #60 sprocket for the center drive wheel is AFU so I need a new assy anyway.

thanks

Dang, you sure have been fighting set screws! Reading your accounts do teach me/others what to be aware of though. Good luck on the rebuild.

[garretttpe]

Yes the set screws are kicking my but. I plan on using grade 8 bolts and safety wiring them to the sprocket and I will also use plenty of antiseize. The idea of a double set screw with the top one ground down flush with no choice but to drill them out is just plain foolish IMO.

From the factory the 1/4" setscrews were double and I've seen a lot of them fail with the tip broken off. The second design is a 5/16" dog point setscrew. You see these until the snapring design came out. If I have usable sprocket hubs I drill out threads and tap to 5/16". Whipper told me he uses dog point screws that stop flush with hubs, antiseize on them with a hose clamp over it so it won't back out. I think this is a good idea even though I rarely find a setscrew type that is reusable.

what i found out when trying to drill mine out, i wasn't going to save the sprocket so i drill a larger hole in the sprocket hub right next to the set screw. then i was able to just tap the set screw to the hole side and it came right out. trying to drill the set screw out itself is real tuff. it's very !! hard. good luck john boy va.

Thanks John!! I really like that one!

Hi All
Thanks for all the advice. I ended up using a dremel tool and a square rotary bit and it took care of the set screw issue in about 40 minutes. I did the oversize hole and tap on another sprocket the other day. Thanks to this forum everyone has a way that worked for them and I had to use all of them.

awesome advice on the 5/16 screw and clamp. I will be using that one for sure when I go back together.

WHIPPER if you see this can you please PM me I am looking for some sprockets. I sent yu a PM and have not had a response back yet.

thanks all

Also, standard length bits are a PIA to get in beside sprocket set screws. I was in heavy aircraft sheet metal for a couple years and scrounged all the foot long drill bits I could get my hands on. You can find them in the right hardware stores. They are a real lifesaver in tight areas.

LMAO, I am an aircraft mechanic and I was using the foot long #30 and #40 bits we have at work, I had to use a dremel tool with double cut carbide bits to get the center ones out.

Last axel was removed today and now to remove the frame and fire up the pressure washer. Hard part is done. I figure I have close to 8 hrs removing all the axels

Kool! Then you know the drill (HA!) play on words. We used to make some crazy homemade tools for special purpose aircraft fixes at Continental. I'm sure you know exactly what I'm talking about. Press on my friend.

thanks so much. It is very true that the wives and or girlfriends are the better half. at least that is what my wife tells me.

Yes I know what you mean I have a draw full of "special tools" I am an engine mechanic by trade, Garrett 331 engines. I have been overhauling and testing them for 28 years now.
