Sprocket Removal Max IV

[awesomedarwin]

Went for a ride on the weekend and the left rear inner bearing completely let go in the middle of nowhere resulting in the drive chain eating up the sprocket to get home.

Now I'm in the process of removing the sprockets from the axle,got the set screws out and have the axle soaking in penetrating oil.

My question is it only the set screw that holds them on? Or did I miss something before I start banging on them with a punch.

Should mention it's a 2004 Max IV

That should be it. They will often rust to the axles so it may take some leverage or strategic hammering to get the sprocket to slide on the splines.

An 04 should have just one setscrew per hole but may have two. Look down into the threaded hole ans see if you can see the axle. I find that the outboard bearing is usually rusted to axle shafts. try pulling the bearing flange loose also to get shaft to move. good luck

Well after a few days soaking in PB Blaster,then beating the sprockets with hammer and chisel, air hammer, heating with a torch I ended up just cutting the axle.
Now I need to order a few parts, does Recreative Industries ship parts outside USA or do I have to find a Canadian dealer.

They do ship internationally but I would call your local dealer too and compare prices since you are having to ship across the border. Also, you can try starting a wanted thread here on the site. You never know when someone may have what you need.

Do you think a 3 jaw puller would have helped?

[azz7772]

should a person in that case use anti-seize on the reassembly?

[awesomedarwin]

That would have definitely helped but the bearing had chewed up the axle so it would have been another challenge to slip off the sprockets.

Don't mean to hi-jack the thread, but as far as sprockets go...how bad does this look? Is it safe to run? I plan on replacing soon, just wondering if I'll be fine for a weekend worth of riding? The new sprocket was ordered from Buffalo Bearings...

The chain will stretch and wear out faster using an old sprocket causing more problems then it's worth.
