The Seca other drive specs

No workshop manual as yet , but i'd like to know the freeplay/backlash/mesh specs on the drive , and no not the drive at the rear wheel , the other drive in the motor , "the output shaft" , it has adjusting shim spacers there and my thing has one shim but in looking and checking [all pulled apart] the mesh , it has none , and it looks like it is meshed too hard in what i see on the spiral teeth faces , so peoples can anybod help?

So , i after the factory amount of freeplay if any between those 2 gears please...
