Wink Wear...

Hi Phil..
I agree with David..some good close up's of third gear and the cluster may tell the story better..sounds like wear on the gear faces..straight cut gears will show this wear and are more susceptible to this than angular cut gears,although all gears wear..prolonged usage of third gear would would induce wear that would only show on those gear faces..
And unfortunately the wear is can not be adjusted ,as shimming the crown and pinion to adjust for proper load clearances..
But it is measurable..put in the old bearings and reassemble the transmission..
Then turn the transmission slowly by hand and feed a length of plastigage through the teeth of third gear...record your clearances..
Then replace the bearings and do the same thing and the difference in clearances should be measurable..If there is no difference it will be the gears..
The consistency of the clearances,which will show up on the plasticgage will also tell you if a shaft is bent or a gear is warped
Enjoy..
