Tore into the 990 today, got it running and took a run with it. Later didn't run and decided to start tearing it down. Brakes didn't seem to work. Is a disc back on gear case. found the nut on the pucks was not tight enough and tightened it up and think It should work. Removed the brake unit, no problem. Disc not! Didn't see a set screw or any pin to hold it on. Two big bolts behind it to remove metal parts, so used those to push on disc. A third bolt I put between case and disc near hub helped push when unscrewed. Made big Snap and started to move. Worked with oil, punches, and finally heat to get it off. My question is ......is that disc really just supposed to "float" on the shaft? It does have a key. Brake caliper would keep it on. OR, is it supposed to be pressed on? I bent it some messing around and some dings in hub from punch and not so nice now. Think I would ever find that disc new or kinda out of luck? Not sure I can straighten this one, but will see what I can do with my press maybe. NOW.....will I be driving it back on or should it just slide on the shaft after clean-up??
