Right,jackobyte had the same problem with his MT.His was melting the spur gear(large). We found that the brake pad on the layshaft had disintergrated and was causing a build up of friction on the shaft thus throwing heat through the layshaft to the spur and over heating it. He has a steel pinion(small) gear so this was not affected.
If you take either one of your gears off you should be able to spin the pinion shaft (clutch bell) and the layshaft freely without any binding.If not and you are using a plastic composite gear carrier(standard on most FG's)there might have been excesive heat build to distort the carrier and make the bearing seats 'sloppy' resulting in play.If so a new carrier and bearings are in order.
Another is you don't have the correct 'mesh' on the gears.If you are a tooth out then you will have this problem and wont be able to cure it until the teeth add up. An MT has a 16T pinion and a 48T spur.
Good luck.

wot u lads mean mesh

 

[paul]

it looks like the big cog could off sliped backwards a bit and the teeth aint joining the little cogs teeth properly its all lined up thought cos ther is 2 screws that line up witht he flat piece of main pin wos cog goes on

wot u lads mean mesh

Ah,got ya now! You mean the layshaft gear and the diff gear:huh:.When someone says 'mesh' it means the way the teeth go together.If your engine is pulled too far backthe space betwee n the layshaft gear and the diff gear will become(as Super said )too tight! What you need to do now is move the engine forward a little.To do this slacken the four engine screws off and pull the motor forwards.If you get a business card and jam it beween the layshaft gear and the diff gear and push the motor towards the back of the car this will in turn serate the card and give you the proper'mesh'tighten the four screws back up and remove the card! should be ok.
To stop the engine moving in the future I have taken the engine out and put double sided tape onto the bottom of the engine mounts to stop the motor from sliding under knocks and rolls.
good luck.

hi paul. its an easy fix. losen up the motor mounts and slide the motor back till it meshes proberly. the "layshaft gear" is what is attached to the motor and the larger "ring gear" is attached to the diff. the motr mounts on the chassis have just a slight bit of play in them and couse the lay shaft gear to slide out. those need to be checked often as its common with plastic motor mounts. alloy motor mount will fix that problem

 

[paul]

ok ive done it done m8 thanks ill test it in the morning see how it goes is it possible to pull it back to much will this do out to my clutch or out ive pulled it back as much as i can cogs are perfect fit in teeth perfect now cogs whent stuf when i pulled it back to much thought ill see how it goes

Hi paul, how long has this gear lasted. I just put a new set on my mutilator and it was slightly out of line and wore alittle straight away but I've got it lined up better now it seems ok.

if the mesh isnt corect you will wear out the cog fast
