The original seal is leather made by Chicago Rawhide(CR) and the width = .879"
The replacement rubber lip seal, D9NN703BB, width = .630"
length of the original sleeve = 1.000"
lengh of replacement sleeve = 1.100"
The replacment seal casing should be pressed to contact the outer ball bearing race with garter spring facing inward... all the way to the bottom. Sleeve champher facing outward.
Hopping the replacement sleeve had sufficient length to handle two new rubber seals, but no cigar.
