National 5827 crosses over to C/R 17599
NAPA currently sources 17599 from SKF
I got 17599 oil seals from NAPA today for my 1947 Custom 2106 but the oil seal lip type is HM21 (cross section) whereas according to my 1970 Chicago Rawhide (C/R) catalog the 17599 oil seal lip type (at that time) was G10 (cross section).
The sealing lip of the original seal was nearly flush (.020" deep) with the face of the seal body. The seal lip of the modern 17599 is .224" deep from the face of the seal body.
The 1.75" dia spindle boss is only .398" tall. If you allow .100 clearance, there is only approx .070" of spindle boss available for the modern 17599 seal to engage.
I placed the seal directly on the spindle boss in its working position, flat side against the spindle. The seal barely engaged the hub.
Then I turned the seal around to find a much better fit but in this position the seal body interferes with the bearing and will not press flush with the hub. Anyone else have any thoughts on this situation?
