Reply To: Water Pump seals ?

[Tom Alexander]

Bills: In regard to SKF Speedo Sleeves, I just put on on a .625 driveshaft to cover the groove the old seal(s?) carved in it below the water pump letting water down into the pinion needle bearings and destroying them and the pinion gear and freezing the gear case. The SKF instructions say not for installation over splined or keyed shafts. Well I drove it over the splines and it went on without trouble, but when I examined the finished product I can just barely see sort of ‘flats’ on part of the seal surface, not all the way around but about a third. I am wondering if the seal will do it’s job with these there or not? Or will the seal happily run over these but maybe for not so long? Anybody have any experience with this sort of thing? Thanks Tom
