Front motor mounts

[V12Bill]

I recently bought a 1950 F1. The engine appears to be a passenger 8BA (the engine is painted bronze and the belts are wide. When I pulled the engine for a rebuild, I noticed that the right front motor mount had 2 rubber mounts and an extra long bolt and the left one had a single rubber mount. The mounting holes in the frame are 20" center to center and the holes in the water pumps are 21 1/8" center to center. I thought that the passenger and commercial engines had the same water pumps except for the belt width.. Could some one shed some light on this for me please.

Any chance one of the pumps is a Merc pump? The foot is higher by about 2". Could account for the width difference as well as the 2 cushion on one side. They were also wide belt like the truck pumps.

If the pump on the engine right side looks like this. It is as stated most likely a wide belt '49 Mercury pump.

OK, I took pictures and the right side is about 2 " higher than the left side, so I guess I have Mercury water pumps. Is that true of both sides? What water pumps do I need to be correct?

Ford truck pumps (like the one on the right) are the usual way of doing it and the pumps are readily available. I am running the Mercury pumps on mine because the ones on the engine were good and why spend money if you don't have to? I did this by making a simple spacer out of 2" square tube. That being said, I don't believe the Mercury pumps are currently available. If I lose a pump down the road, I'll probably have to go with a new set of truck pumps.

Speedway is one source for the correct pair of pumps.

So let me get this straight, the left side pump on a truck and a mercury are the same. I only need to get a truck right side and I am in business?

The left side pump on a US truck and Mercury are not the same. The Mercury pump is totally wrong for your application. It was something that someone did because it was most likely all that they had. Yes get the truck right side.

Sounds like a chewing gum & bailing wire fix to me. I saw a lot of that kind of Rube Goldberg fixes on old farm trucks when I was a kid. Somebody had a bad truck pump but just so happened to have a Merc pump that was still usable. Likely not the first time it ever happened.

Use it up & wear it out. Make it do or do without.

After 67 years of passing from owner to owner, things happen. As near as I can see, the passenger car engine was the only major change. I ordered a pair of truck water pumps from Summit last night. Thanks for setting me straight.
