I first start out sanding the rings with 200 grit to get them flat then working my way up to 600 grit. Then I put a little diff lube into each hole and a light smear on the rings.
Reassembly D-ring, Spur, D-Ring ,Wheel Hub, Slapmaster Spacer, thrust washer, nut. The slapmaster spacer rests on the bearing. I then tight lightly and beak in each side at 1/4 throttle. O this is on a 12R5 with the 10R5 b/l conversion. I do have the correct slapmaster 109. I think?
Thank you for any help

I have the exact setup you have, and mine works flawlessly and reliably. #109 is the right one (you couldn't actually build it with the wrong one.) Maybe the spacer is crushed? Is the little lip that goes on the bearing side intact? Also, how is the nyon locknut? The nylon should be quite firm. It should really hold it's setting. Beyond that, I really can't say. Check the thrust bearing itself. Are the races intact? Is the brass part with the balls intact? If all else fails, don't hesitate to contact Brian himself, he is always responsive and supportive.
