Re: Water pump won't fit now.
Adding an extra gasket or two may shim the pump out far enough to allow installation of the pump , without grinding .

Re: Water pump won't fit now.
The dynamics of this is that the water pump draws the water out of the block too fast and it creates a low pressure with in the block. Any water close to the boiling point, flashes into steam at the lower pressure and the steam then displaces the water in the block. Hence you have more water coming out of the water pump than is pulled in from the bottom inlet. It is the old school teaching that water boils at a lower temperature on the mountain top than the higher temperature that it boils at sea level. A pressurized radiator will very well raise the boiling point of the water in the system thereby preventing boiling over at the old lower water temperature.

Re: Water pump won't fit now.
When I finally grind and get everything to fit correctly should I use Permatex #2 or spray copper gasket sealer on or just install so it would be easier to remove if necessary?

Re: Water pump won't fit now.
I like to use Indian Head shellac on the ones I do.

Re: Water pump won't fit now.
I like Copper Coat. In the late 70's I had to remove a Model A head to do a valve job, and some fool used shellac on the head gasket. I used a puller on the head, and had the whole front of the car in the air, and the head wasn't budging. I also had to use a hammer and thin blade to keep working around the head gasket. It took hours just to get the head off.

Re: Water pump won't fit now.
Well I work on this fitting up this morning and have figured it out. Pump will not fit over studs,mounting holes are off significantly enough that it will not fit past the fine thread end of the studs. May work with bolts or drilling mounting holes much larger but they are off quite a bit. Bratton's ofcourse say that I am the first and only one to have had this issue and even though origin was Bratton's to Mac's they cannot and willnot offer a refund or replacement. I actually bought this from another Model A guy who probably had the same problem. I was getting ready to buy a pump he had one for sale,not any cheaper actually but at the time Bratton's were out of stock. I figured he was helping me and I was helping him. Oh well at least I have new parts other than the housing I can use.

Re: Water pump won't fit now.
Check your studs. Some of the new studs are noticeably larger between the fine thread and course thread, this may be the problem.

Re: Water pump won't fit now.
I like to use the fake stud bolts. It makes future repairs easier.

Re: Water pump won't fit now.
I also prefer the fake stud bolts . I would redrill the mounting holes before I would replace the pump housing .

Re: Water pump won't fit now.
I wonder if one of the studs in the head broke and someone drilled and tapped it off from the correct position.

Re: Water pump won't fit now.
But the pump that I am replacing fits,same size diameter bolt holes,same diameter boss and it fits in place.I will know for sure today as I am getting another pump from Bratton's my expense and if it doesn't fit I know I either have another problem or need another pump source. I really do believe that holes are drilled off of pump boss,probably close to 1/16" just eyeballing.

Re: Water pump won't fit now.
Oh wise one,yes Masster you are correct. The pump arrived from Bratton's and it too does not fit. It has to be that someone has broken a stud off years ago and rewelded or repositioned the threaded holes. The old pump fits and holes do not look enlarged or elongated that I can see. I do remember when I took it off it was bolted not the studs I replaced with. I had a great head but opted for the old one that was on the engine because of the Ford Script on it,sold the other head with an engine I had. So I am going to make this work somehow before I change heads I don't have 100% faith in the rest of the engine anyway. So going to get it running nd as I have been doing waiting for a good engine closeby. It seems to me more street rodders than ever are taking apart restored cars they are buying cheap. Thanks for all the help but that was a tricky one especially since the old pump fit.I think I will also get the bolts that look like studs.

Re: Water pump won't fit now.
According to the Standards and Vince's site the script head was a service
replacement after 1931. http://www.fordgarage.com/pages/ABcy...comparison.htm Bob |

Re: Water pump won't fit now.
If the head that you let go wasn't a higher compression head , I wouldn't worry too much about it .
