Thanks for the reply, but the description states "The LUBRIPLATE "100" Series Products are excellent water-resistant lubricants". I want to find a "water soluable" grease and I can't seem to get any info on that although many advocate using suc ha product without giving useful details such as product name and identifying numbers/letters. Can anyone out there help? Thanks. Don/WI

Thanks

There is a boss in the head that is a "stop" for the shaft. What happens is that the shaft/boss gets worn thus creating the movement you mention. An easy and reliable fix is to buy a "collar" that all the suppliers sell. About $10 if memory serves and comes with complete/easy instructions to fix the problem.

If you don't want to remove the water pump to add the steel collar to fix the shaft in place there is another temporary "Farmer fix". Buy one of those cheap Chinese plastic replacement ends for a garden hose sold at all of the big box stores. They have a two piece plastic collar that captures the garden hose around the hose end that is inserted into the hose. It is fastened together with two screws. For the $1.50 cost it should last you until you are ready to go through the work of removing everything to remove the water pump. You can even use a leather water pump cover so no one will see it.

Be sure the thrust washer is in place, or this can happen.
It doesn't take much extra end play for the thrust washer to come out of the impellor pockets and start wearing the shaft.

Thanks all for the information, suggestions and 'heads up' as to what can happen. Will probably use the cheap garden hose thingy till order out the 'collar'. I was thinking of turning one on the lathe using delrin-very durable slick plastic.

the water pump can be removed without removing the radiator if the fan is a 2 blade. You will have to unbolt the radiator rods and pull the core forward for clearance. Place some cardboard over the core to prevent poking the core with the fan nut. Place protection over the front of the core to prevent poking it with license plate nuts. The play can be reduced by building up the end of the shaft with brass, or more commonly and easily with a collar that slips over the shaft between the fan hub and the front bearing retainer. The collar is locked by a set screw to adjust the play. .010 is the desired amount

The water pump can also be removed even with a four blade fan ... without removing the radiator !! Just remove the 14 nuts holding the head down and remove them both at the same time !!!

y'know, you're right about that. LOL

this might have been answered hereinabove but it is not clear to me: how does one tell by looking if one has a leakless pump or not, and whether or not it requires lubrication. Some of us bought the pump years ago and can't remember. Some of us can't remember what happened yesterday.

Well, IMO there is not a 'textbook' answer to this because there have been several manufacturers of these. I guess to start with, if it ain't leaking and never has, in all likelihood it is already a leakless.

The front grease fitting is the one that generally needs it the worst, so a light shot of grease won't hurt it. Some seals can be displaced shooting grease into the rear fitting so my suggestion is leave it alone until there is a noise.

Also, sometimes the gland nut packing has been replaced with a seal and you can see it when you unscrew the nut. On some though, it is sealed and should not be disturbed. I guess this is one of those times when let sleeping dogs lie until they start growling, ...then add grease.

Any maintenance you do on the water pump is a good thing. A neglected part of the motor in my limited experience. Starting with lubrication, loosen the fan belt, remove it, give the fan a spin, inspect for travel forward, and back. This should tell you if you to proceed with the work of removing the pump assembly and reworking it. I believe, based on the times I have pulled a waterpump, that you need to pull the radiator first. Yeah, you will find more things to fix, but that comes with owning the car and keeping it maintained. No free lunch.

I just took my water pump off today because there was 1/4 inch of forward travel of the fan. What I found was that the impeller was not pegged to the shaft and it had moved back . Moved it back into place and drilled and pegged it. Hopefully no more problems. Mine is not a leakless pump but has not leaked a drop in 2 years!

[Dick So. Cal.]

When I check the oil, I put the drop of oil on the end of the dipstick on the waterpump shaft where it goes into the bushings. I have done this for quite a while and have never had a waterpump problem.

Try it. You'll like it! And it's free.

Yes.
With the earlier four blade fans though it's a different story.
