Is there anyone who can tell me the difference between a 1960 water pump and a 1961, other than $55? The 1960 pump is Cardone 58-105. The 1961 pump is Cardone 58-106. Thanks in advance for your wisdom!
I'll post my own first reply. Carefully checking the CARS catalog reveals a clue. They use their own part numbering system. The 1961 w/o AC pump is listed as part number WP591. The 1959-60 ALL pump is listed as WP591EI. I think that these are really the same part. I welcome any other input.
Im not sure about the numbering, but you might want to call. The "E" might be for exchangeo No: . You might have to send your core in for rebuild
Looks to me like I have solved this one. The 1959-60 uses 58-105. The 1961 w/o AC also uses 58-105. The 1961 A/C uses 58-106, which has a shorter shaft, most likely because the A/C condenser moves the radiator closer to the engine. Thanks!
I believe the shafts are different Bob. IIRC, the non a/c one is more difficult to find, I think I ended up having mine rebuilt / exchanged through a local parts store.
I sent my water pump to Arthur Gould Rebuilders out on Long Island. As it turned out though, I never noticed before sending it that my water pump is the short nose version. There's an aluminum spacer that bolts between the water pump and the pulley. Since I work mostly at night and am half asleep while I am, this fact that the pump was the short nose version totally escaped me until I pulled it out of the box . :Brow: I wonder if anyone else has background on this. Was this a retrofit? I have seen it on a couple of other cars. Most people bolt them between the pulley and the fan, though, from what I have seen.
Can you take a picture of it ? So I could eventually replace my long nose 60 pump with a short nose 61 ? 62 + ? and a spacer ..... ?
I'll be glad to take some pics for you when I redo the water pump gasket very soon. The '61 cars with no A/C that I have seen by searching for pictures all seem to have this aluminum spacer and a short nose water pump. But as opposed to what I have seen elsewhere, my spacer was bolted between the water pump and the pulley and is hidden by the pulley. I actually like this as it makes the engine look stock, and you really can't tell without a good look that the pump is the shorty. Also, my pulley bolts are homemade. I am not sure why, as they would need to be the same length regardless of the spacer's placement, but someone simply took some threaded stock and welded nuts to lengths of the stock to make bolts. I reused them- you really can't tell when they are in place.
Obviously it makes a big difference in how it lines up with the generator and PS pulleys, so that would have to be different on the 61 as well. I would take a picture of mine, but unfortunately it's not here. Supposed to go there tomorrow, will have a look see.
*slaps head* Of course, you are right. Why did I not think of that? Geez, what a maroon. I couldn't put the spacer after the pulley if I wanted to - the pulley would never line up. The plot thickens...
The with A/C pump is the short nose pump. That one seems to be much less rare than the other for some reason. I imagine that the long nose was more prone to bearing failure.
This is my 60 long nose..... Are you saying a 61 non AC would be the identical part ? and a 61 AC or 62 would fit but with an extension between the pump and pulley ?
Bob after seeing that picture I think mine is short also, and AFAIK, the spacer is on the outside, next to the fan. I will check tomorrow for sure.
The '61 non-AC pump is supposed to be the same as the long nose '59-60. But every '61 I have seen has the shorty and a spacer.
