Can't remove pinion gear

[ronnyboy]

hi there, i dont know the exact threadlock variations, but maybe it helps:

back in the day when i raced bigscale, there where some things that needed blue threadlock, just to secure but easy to unscrew again. if you didnt, your full alu car fell apart :P

We also learned never to put threadlock on a shaft, put it on the screw, screw it in and whipe all excess lube off so the shaft stays free of the goo.

near the motor and gears, blue wasnt sufficiant and we used green one. the red one was never used because of the problem you are having now.

with the green one it was only posible to get the gears off this way:

take a little torch or even a lighter will do, hold it against the shaft at the piont where the pinion is stuck till you see the metal sweat, about 40 sec.

then secure the pinion firmly so you can tap the shaft with a smal hammer. just gentle taps and if that not works, re-heat again, works everytime, but my advise is that you dont use red anymore.

if above fails than there is the option to put the shaft in the freezer (wich will shrink the shaft only minor) the next day heat up your pinion (wich will expand only just enough to take it off)

my pinion stays on perfectly with blue. and if it where so that the bugger got stuck, i just heat up my screwdriver and stick it in the screw for a few seconds. that way only the screw and its thread will heat up, instead of a big 5mm shaft witch wont heat up so easily.

hope it helps.
