4th gear mod help
 

can i use a reg. ZZMt pinion gear for the 4th gear mod, or no....

The pinion only has one set of teeth so it cannot change the drive ratio. You have to use something like a zz idler where it goes from ~18 teeth to ~6-7.

im still using the idler but for the pinion gear will zzmt work : yes i just found it will HEHEHE.

I've done a small amount of work with gearboxes and posted several tutorials on my ZZ website--www.gcrossett.com/zipzaps--which you might find helpful.
