Help needed please

My FG MT's rear big gear is not meshing with the layshaft gear. I have had this problem with the same 2 gears and I am now thinking that both gears are worn and that is why it's slipping. I have another rear gear (big one) and I am wanting to know since I have a 2 speed if I can just use the 18 tooth pinion gear on the layshaft.

You can change the pinion gear with many different gears it will just mess with the total gearing. Bigger gear more speed less power. Have you tried spinning the bad gear around on the shaft and using the good side of the tooth? I had that annoying clicking on my FH when I 1st bought it due to bad gears and had to buy new ones.
Good luck.
Is it hard for you to get FG parts? I think alot of the DTX parts should match up for a quick temp fix.

I am running a 2 speed also, my gears are just barely touching. I guess I will just buy both gears and go from there.......

make sure you have alloy large and small motor mounts or it will keep happening , if problem still continues and you want a tough rear end upgrade to the alloy diff holders as well it stops the flexing on the diff as well
hope this info helps .

Thanks, do you have the part # for the dif holders that are metal. I have one of the metal motor mounts I will get the other one.

I have not had a 2 speed. Are you saying because of it you cannot get the correct mesh on the spur and diff gears? I would think you should be able to get the gears to mesh just as if you had a single speed?:blush:

the 18 tooth is too big for a replacement on the layshaft , i no longer have a Fg but i think yours is stock 14 tooth if im correct .if you bought a 15 tooth or i even think someone has put on a 16 tooth then it has more room to mesh , but from the sounds of things you might as well buy a replacenement gear and swap them together 2 new gears so they wear correctly
here the alloy diff holder part number fg#4476

Thank you everyone, I found out that the 18 tooth is to big, so I guess I am going to get 2 new gears and the alloy diff brace and motor mounts and try it again.
