Gearbox Flush

[FloydWestwood]

So im gonna change my gearbox oil, ive read all the previous threads about what oil and how to do it...but not much is mentioned about flushing the gearbox out.

i know ive crunched a few gears here and there so its pretty safe to say im gonna find a fair few shards of teeth once i drain the oil. so....

should i flush out my gearbox? if so, should i just use water/detergent/oil/spit/anything that cleans out gearboxes for people that crunch gear changes when driving ????

There is a magnet on the drain plug from memory. That should attract most of the things you don't want in there.

Just drain and re-fill, no need to use water or detergents, etc (infact DO NOT use water or detergent).

If you have the additional cash, then you can buy additional gearbox oil and flush it, then refill it with the new oil.

I have read in a thread that you can fill the box with kero, then start the car and without the clutch you push the gearstick into each gear as if you were changing gears but not so hard. Apparently that allows the synchro's to open up and cleans them, then drain it out and fill with oil.... Thinking of this as it sounds about right but not 100% sure... also cant get the drain plug out!!

thanks guys! i ended up just cleaning the mag plug. theres was so much crap on it i was a little shocked. oil was nasty too, but the change in new oil made the gearbox feel awesome, its almost as if i've done a complete overhaul. lucky!
