hi! everybody
iam rebuilding my 13b n/a with 12a end plates. now there is a difference between 12a and 13b stationary.the 12a stationary tooth are shorter compare to the 13b.now it is ok to use the 12a instead of the 13b and the question is made because i see that the tooth from the 13b when i start to put the engine toguether are very close to the rotor bearing and as far i understand they expand under heat.so i need an advise on which one to use.thank you

 

Ur building a 13b so use the 13b statioinary gears.

 

There's a 5mm difference.

 

Just cut a few teeth off, and you'll be fine.

 

thank you

 

Just take it to a bench grinder. It just sits there, stationarilly, so it's not like it'll be out of balance when you grind the gear teeth down. I'm kidding. Don't grind your gear. Get the correct one for the width of rotors you're using.

 

i will be using the ones from a gsl-se

 

That will work great.
