I was working on a 350 GTR and i was assembling the driven gear part number 2411-9000.
But before that there is a needle bearing 09070-113 that goes on the counter shaft.
If you look at the parts book it shows 2x bearings and a spacer in the middle, on all the engines
I have looked at the needle bearing is one piece i Wonder when that part was replaced etc
I will look into this and find out why.
Thanks.
Steve.
