They didnt say this in the manual !
Saturday night i was in the process of replacing 2nd gear in the menace and i decided to replace pinion and clutch also. After getting the pinion off and removing the .21 thunder tiger i ran into a bit of a snag. The nut that holds the clutch on the motor shaft would not come off. Keep in mind that i am a power lifter and a big ol boy and i consider myself somewhat strong. I fought and fought and finally got it loose. The problem was the lock tite that was holding that baby on. RED LOCKTITE is some serious chit and schumacher never mentioned this in the directions. I went ahead and put some back on the shaft nut after installing the new clutch and gears.
