Model B 4 cyl water pump?
 

I see Mac's discontinued the water pump I was waiting to order. Anyone have one or a rebuild kit or a good used one? I really just need the impeller as the fins are rotted off mine, but would take about anything.

Try posting in the "Swap Meet" section.

Re: Model B 4 cyl water pump?
 

Try Renner's Corner. They are the "go to" guys for Model B parts. rennerscorner.com, (734) 428-8424

PS, I am glad you put this in the swap meet section as fourfords suggested

Thanks Charlie, they have the rebuild kits but looks like they dont include an impeller. They also offer rebuilt units for $500. I'll keep looking or give them a call to see if they have any impellers they would sell.

Re: Model B 4 cyl water pump?
 

Hey 32B,
Wow, $500 rebuilt ! There are two or three ways to go.

Re: Model B 4 cyl water pump?
 

Macs have just discontinued their new reproduction model B water pumps. I bought one a few months ago and the front taper on the shaft was a little off on its angle and after an hour or so running the front pulley came loose and would not retighten. Contacted Macs and they eventually refunded my money. Had to send them photos of the pump shaft to prove their pump was poor quality. All a big waste of time especially the removal of the Headlight condutes, grille and radiator twice so as to unmount and remove the pump. Macs service and quality has slipped of recent times and I doubt that I will buy from them any more after having fairly good service from them over many years. I think Dave Renner is you best quality option but of course fairly pricey. He can supply all the pump parts you need even though they are not all listed, try him, great to deal with. Regards, Kevin.

I may have what you need. Will look tomorrow if you email me at [email protected]. Do you need a 1932 or '33-'34?

Re: Model B 4 cyl water pump?
 

There are adaptor castings to put a 36 V/8 water pump on the B
engine. Cools much better than the B pump. Google ford B pump
adaptor. G.M.

Re: Model B 4 cyl water pump?
 

i had a 36 water pump on my A. the fan took out the pump

Re: Model B 4 cyl water pump?
 

I have heard about the fan issue. I am on my second fan and radiator due to failure. Im trying to stay original and avoid the adaptor option. At this point im either going to send mine to renners or see if anyone has one for me. Thanks everyone

Re: Model B 4 cyl water pump?
 

I have had one on my B engine for close to 30 years. Went on a lot of long
tours. Cools real good and never had a problem. I'm not sure what fan I
am using, I think it's a 4 blade. G.M.

Re: Model B 4 cyl water pump?
 

There's more to using the V8 pump than just buying the adapter. You may or may not have a better water pump, but you no longer have a fan unless you modify the V8 water pump pulley to attach a fan. That strikes me as something that would have to be done very carefully in order to avoid fan imbalance.

Re: Model B 4 cyl water pump?
 

Hey G.M.,
Curious as to how you attached a cooling fan to the V8 pump on you B engine ? Currently , there are no such adaptors made to put a fan to an early V8 pump. Kling's used to make an adaptor for such fan use to early V8 pump. He told me this year, that he hasn't made such adaptors for years now...'not enough demand' to justify making them.

I have three different alum adaptors to mix/match various pumps to application, so am aware of those. Also , have good early V8 pumps that I'd like to use....but have to have that adaptor !

Re: Model B 4 cyl water pump?
 

I don't have any information on these pictures.

Bob

Re: Model B 4 cyl water pump?
 

Hey Bob,
Thank you for those pictures :) !
Wonder if that is Kling's 'invention/equipment' on the front of V8 shaft ?
Maybe someone has one or can identify this , over on the Model A side ?
I don't know how to get these pictures over there with questions.

I have the cyclone adaptor, one of three different adaptors on the shelf. Also have the other parts shown...except that fan holder ! Doesn't look complicated, eh ? Wish I knew machining, as I know that lots of inquiries for that adaptor in the past.

Re: Model B 4 cyl water pump?
 

To help with 32B original question/search, I've got two (slightly) different rebuilt '3? pumps. Here are pictures. Can you tell which is which as to years ? How many versions were there between '32 and '34 years ??

Re: Model B 4 cyl water pump?
 

Before I went to a V8 pump I think I would add some speed equipment most of which uses a Model A water pump.

Charlie Stephens

Re: Model B 4 cyl water pump?
 

Unless you are getting into fine point judging there ae two pumps, '32 and '33-'34. The difference is the length of the shaft which allows for the radiator sloping back in '33-'34. You can usually spot the difference by looking at the spacing of the grease fittings on the left side. I can't tell for sure from your pictures.

Charlie Stephens

Re: Model B 4 cyl water pump?
 

Those are both '32s with two of the many casting variations encountered. There are even a few with Ford script on the casting and some aftermarket ones as well.

The outer ends of the grease fittings on the '33-'34 version are only about an inch apart.

Re: Model B 4 cyl water pump?
 

Hey Charlie,
Now, that's just bragging ...geeze, nice engine bay :eek: !
But, I wouldn't do that ! Well, maybe just one pic of lonely B in waiting:cool:

BTW..thanks to David and you for you id help here !

Re: Model B 4 cyl water pump?
 

That unfortunately is not my engine bay. Just a shot I took a couple of years ago at LARS because I thought it was a nice engine bay.

Charlie Stephens

Re: Model B 4 cyl water pump?
 

I'm not sure if the pulley is one of the special ones or if it's a 36 type
with the 4 threaded boss's for the fan to mount on. I'll take a look and
get a few pictures if I can. ALL 36 type impellers are not the same,
there is the truck type with a little larger impeller and the most used
type with little nubbins for impellers. Then there is Skips 36 type
impeller with large longer streamlined blades. There are flat surfaces
on front of the stock impellers that block and disturb the flow where
Skips impeller is tapered to improve the flow. Stock 36 pumps deliver
55 gallons in 5 minutes and Skips 36 pump delivers 92 gallons. This
makes a big difference in cooling. I did this conversion 30 years ago
and don't remember. I have a complete machine shop and may have
bored and keyed a stock 36 pulley to fit?? G.M.

Re: Model B 4 cyl water pump?
 

Thanks all. I am in need of a 32, but I will measure just to be sure. Looks like this thread could be helpful for people other than me so glad to see it :)

Re: Model B 4 cyl water pump?
 

Hey G.M.,
Thanks, would be nice to know !
Skip almost doubled the Ford stock output, wow. Maybe ford should have him a an engineer ! Or is this a case of tooo much is not too good ?

Re: Model B 4 cyl water pump?
 

32-B, If you run out of options I have a new 33-34 shaft with impeller pressed on that might be useful for the impeller part if it was removed and pressed on the longer 1932 shaft. Otherwise, I have always wondered if a Model A impeller could be used in place of the 32-34 impeller. Some guys will grind down the fins on the "A" to slow down the flow so maybe it could move enough water on a Model B?

Re: Model B 4 cyl water pump?
 

I got a couple pictures of the 36 water pump on my 32 B engine
this afternoon. It appears to have a plain stock 36 pulley. I thought
I used a V/8 pulley with the 4 cast boss's that hold the fan on but
that was not the case. It looks like I made an aluminum adapter/
spacer over 30 years ago and just don't remember. I'm not sure
what the 4 bladed fan is from but it runs true and is good and
tight. G.M.

Re: Model B 4 cyl water pump?
 

Wow thanks GM. That actually doesnt look that far off from orignal. Maybe I could live with that, but for now will continue to look for a 32 pump.

Re: Model B 4 cyl water pump?
 

Sacramento Vintage Ford shows a 3-bolt fixing pump at $175.00 part Number 00473-1-12 and a repair kit at $95.00
part Number 00473-1-3

Both for 32 Model B

Re: Model B 4 cyl water pump?
 

I have a water pump on the way, thanks guys.

Re: Model B 4 cyl water pump?
 

Hey G.M.,
Thanks for sharing these pictures !
I like the width of your adaptor toward the radiator.
HOW did you fasten the adaptor to the V8 shaft to keep it in place ?

Re: Model B 4 cyl water pump?
 

I don't remember, it was 30 years ago. G.M.

Re: Model B 4 cyl water pump?
 

OK. The pump that I got leaks more than I can live with. I ordered the rebuild kit from renners, he was very nice. Has anyone here rebuilt these before that can walk me through it? The instructions aren't very clear. Any special tools required? looks like most people recommend drilling and pinning the impeller? I have a press and a drill press. Any other tricks? I was a mechanic for years, just never done one of these.

Re: Model B 4 cyl water pump?
 

It's a pretty straightforward process. The attached exploded view may be helpful.

Re: Model B 4 cyl water pump?
 

Have you checked the packing??

Bob

Re: Model B 4 cyl water pump?
 

Thanks David. That should be very helpful. Bob I haven't. When I got it the bearings felt rough but thought I would give it a whirl. It def needs a rebuild and not just some packing. So stock the impeller is not pinned to the shaft? Just pressed? The rebuild kit came with a new shaft, is there an advantage to replacing it if its not tore up? Guess I'll just give her the ol take it apart to learn how to put it back together.

Re: Model B 4 cyl water pump?
 

NOS B and '33-'34 four cylinder service part impeller/shafts show up both pinned and unpinned, just like NOS V8 pump impeller/shaft assemblies.

Re: Model B 4 cyl water pump?
 

I bought a leakless pump from Macs about 8 yrs ago. Has never leaked and still going strong.

At least one feather in the cap for Macs!

Re: Model B 4 cyl water pump?
 

water pump is rebuilt. only tricky part was the measument on the bearing sleeve but the instructions were clear on that. Thanks again everyone, glad it didnt cost me $

Re: Model B 4 cyl water pump?
 

All I can brag about is that I have a good camera, the engine belongs to someone else.

I know that this is an old thread, but who is Skip?
