64 Cadillac waterpump

[1964deville]

Hey Guys,

Mine's finally ready too. New timing set, waterpump and apart from that some regular maintenance stuff like belts, hoses, filters and oil. We're ready for some nice weather 

Thank you all!

Guys,
On the issue of Harmonic Balancer removal and replacement.  You are probably aware that Cadillac seems to be the only Mfg. that uses four bolts on the damper to hold the damper pulley.  You may also note that most "universal" damper tools are set up for three bolts.
In the shop manual of all years with this feature, Cadillac references a special tool, manufactured by Kentmore for this task.  Kentmore is still in business (SPC Corporation) and they have a version still available.  Costs a couple of hundred bucks and it took about 4 months for mine to show up, but if you are going to be doing any damper removal/replacement OR on the later models where there is a crank hub behind the un-boltable damper (pulley actually),
it is the best money you will ever spend.
Regarding pulling the timing cover with a broken bolt through it without pulling the pan just remember that new or even serviceable timing covers are near non existent so a little extra time can prevent the (essentially) loss of an otherwise good engine.
Just a thought (or two)
Greg

I am faced with this same dilemma. I went looking, and my balancer puller, for some lucky reason, has 4 slots. Since I know I bought mine at some regular auto parts store, and it could not have been expensive, perhaps more can be found.

Greg,

Forgive me for nitpicking, but could you please take a look at part # J-23523-F and confirm if that is the right one. I`m not sure the right part number came up when I copied/pasted the link.

I want to be sure it`s the correct part when I gotta spend $ 340,- plus taxes plus shipping.

I will clear with Kent-Moore as well.

Sorry for bringing this very old thread back to life - I found it during my search for the tool mentioned in the shop manual where the number J-21052 is mentioned. Is J-23523-F the correct replacement tool from Kent-Moore? Can anybody confirm?

My Kent Moore catalog (1969) does not show the J-23523, but the J-21052 is shown.  I attached a clip of the listing in the catalog. 
This is a special tool for Cadillac 390, 429, and 472 engines.  As this is a 1969 catalog it does not list the later engines that it would also fit. 
Notice that the puller has four holes as does the harmonic balancer. 
The one pictured above is a generic puller and is designed to be use with two or three bolts, but not all four.  Someone mentioned that only Cadillac has four bolts on their harmonic balancer.  I have used that type of puller but it is not as good as the one I made.  If you do use the universal one be sure you use the right two holes.  When you install the puller be sure the center bolt goes directly on the center.  If it is a little off move the bolts to the other two holes and check it again.  The puller will only work if the puller is a bit off center.

Thanks Glen,
J-23523 looks very similar to J-21052 - see attached picture. I think it could work and be basically the same, but I am not sure...
