Water Pump Seal for '51 Packard 288
Posted by Larry51 On 2011/10/23 1:43:09
Hoping someone can help me figure out which is the correct seal for my '51 288 Club Sedan, (and if I maybe I can get one in Australia).
Would like to source the seal here if I can, especially after discovering that Kanter no longer supplies pump parts (- just complete exchange pumps now) and some others don't do seals on their own, just kits. I've got a new pump shaft & bearing so only need the seal now. Plus - core freight freight to US will cost a lot, and I have a press to do the work anyway.
I've pulled apart the two pumps I have and one has a different seal to the other. (One seal is incomplete - looks like it has failed, and the insides are missing, only the case remains. Plus, I don't have the shaft / bearing for that pump). So question is, which one of the two (if any) is the original seal? Did Packard do two different types of seal? I couldn't find a post on packardinfo that relates or has photos, although there is some good stuff like at
Water Pump Replacement
The manual says there is a bronze bushing on the shaft and I have one pump with the bronze bushing still on the shaft, but the seal that is with it doesn't look like the correct one. Not quite sure why the bronze bushing is needed either. There is a lip on the fan end which might deflect water so looks like it might be an added safeguard to help prevent water from getting into the bearing. 22nd and 23rd series pumps had part 5.1927: 'Slinger - Shaft, Water' which wasn't included in 24th series pumps.
An incorrect seal might be too deep and place too much force on the mating surface. One not deep enough won't seal properly, so what depth is correct is the question.
It appears the seal mates directly onto the end of the impeller, without there being any 'thrust washer' used (ceramic or otherwise).
I can post more photos and also provide measurement details if necessary.
If no luck with finding a source here, can anyone recommend a supplier in the States who will do seal only and will know the correct one?
Pump #1 with seal still intact
My second pump - seal removed - showing where seal is installed
Showing the second pump and the seal that was removed from it. Different style of seal to that in pump #1 . . .
Shaft (ex-pump #1) showing the bronze bushing with a lip, pressed onto shaft. Workshop Manual mentions this bushing.
The end of the impeller - needs dressing if the seal mates directly onto this end surface!
