Terra Tiger keyed shafts

[simpleton7016]

Any tips for ketting the "keyed" shafts out of the TT18's? I got the rear shafts out, but the front 4 are real boogers. I did get all the clips removed....just need to get the sprockets off the axel. Once I get the center bracket out, then I can do it, but I can't seem to get enough clearance on either side to get that center mounted bracket out.

Also a tip: all the bolts through the bottom were rusted pretty tight. Rather than smash my knuckles all to heck, I just spent a half-hour with a grinder and ground all the heads off of the bolts.

Stock tip: Invest in anti-seize cuz I am going to use a lifetime worth when I put these things back together!

I think your in for a tough time with those shafts. I've been there done that so to say. Being a machinist I had to make two small hydraulic jack cylinders which were fixed to a thick plate which in turn clamped to axle shaft out near the flange (hard to describe). I then had to shim inside the body to the sprocket before I jacked. I had a couple of axles that took six tons of pressure before they submitted to my determination

If you go this route by what ever means you can expect to replace (weld) on new sprockets to the old hub as they get destroyed (think distorted) in the removal process

Soak with penetrating oil before attempting to remove....good luck, Mark

That's what I am afraid of, but thanks for the advice Mark. I just borrowed a big slide hammer and I am hoping that they will come free with some good whacks!!

Side hammer should do trick on them. One axle has to be out too remove center bracket! Also take big hammer and flat drift and hit sprocket on top of key way and around it to loosen. And we have heated sprocket also. Good Luck! Call if you have any questions.

Dang, I got your advice too late Jeff. The slide hammer worked on the front axel. Middle one was still too tough. I ended up taking a 12" piece of 3/16 flat stock and held it on the ridge near the center bracket. At a 45 degree angle, I could get some pretty serious whacks with a minisledge. After a while, it did move, and yes, once the bracket was off, I could get at the axels directly to hammer them out. I didn't even distort the axels too bad. Savable me thinks! I wish I would have thought about tapping on the keyway though....good idea.



Thanks to all for the advice
