Lower end question

Would there be any reason to remove the small locating tab from P/N 414-40 gear shaft bearing washer? This is the washer on the outer side of the pinion shaft bearing just inside the snap ring. I found that it had been removed when I took my bottom end apart.

Re: Lower end question

Some of the replacement races that were available years ago had the hole for the tab located too far towards the gearcase in relation to the snap ring groove. This would not allow the thrust washer to sit square up against the ring, which would cause the bearing assembly to be cocked in the race and stand proud of the thrust surface on the inside of the race. The bearing assembly must sit a minimum of .010 below the flywheel thrust surface on the race. I have narrowed the tab on the washer, took a small stone with the pencil grinder to the hole to open it up, or a combo of both to make it right, but cutting the tab off is the easy way.

Re: Lower end question

This question is in reference to P/N 421-40, oil retaining bushing on the sprocket shaft. I have the later version that uses a lip seal. The service manual states that this part is a press fit in the case bushing. Which direction does it press in from? I have to change the seal in mine and would like to clean up behind it so I can get everything sealed up good. The previous builder used silicone which came loose of course.

Re: Lower end question

Never mind. I got it out. Previous builder did other stuff that caused the problem.
