gear boxes are not my strongest point.only ever took one apart more than 40 years ago.so buddy crashed his box and has chipped some teeth.as we have done 3 toyota conversions we had some old boxes in good shape lying around.pulled the top off to be sure they were all there.at first glance i saw what i assume is first gear ring. top shaft rear most gear. straight cut gears. no synchro.took a look..oh bugger its missing 2 teeth.opened up the second box and huh! same gear missing 2 teeth.rotate the shaft and it has 2 teeth machined off every 8 teeth.go back check the other box same thing.
so can some one enlighten me as to why they are missing 2 teeth every 8?
