8BA Type Water Pumps ID Car Truck or?
 

So have a standard type 8RT water pump.
And two other similar water pumps both these pumps have the spacer bracket attached to suit engine mounts.

Front casing to pulley centre: 2". wide pulley.

1: Standard Pump RHS. Water outlet to bottom of mount: 1 3/8"

unknown 8BA Type Pumps

2: LHS. Front casing to pulley centre: 2 3/4". narrow pulley
Water outlet to bottom of mount. 3 1/4" with bracket removed

3:RHS. Front casing to pulley centre: 2". narrow pulley.
Water outlet to bottom of mount. 3 1/4" with bracket removed.

Questions.
Pump 2. This pump pulley sits out 2 3/4" is this a truck pump?
Are both pumps 1 & 2 truck pumps due to height from water outlet to bottom of mount.

The pumps 2 & 3 are with an engine to be rebuilt but due to LHS pulley being 2 3/4" to pulley centre as opposed to RHS pulley centre of 2".

Would be grateful for any info. All 3 pumps are 8RT type pumps.

The only '8RT' type pump with 'U' shaped spacer bracket that comes to mind is the '49-'51 Mercury pump.

Early Merc pumps used the spacer under the mounting ear on the pump. The earliest ones were wide belt and IIRC used more of a square spacer. The later Merc's were narrow belts and used the U shaped spacer. Mac Van Pelt might be able to provide more definite info on the years of the pumps. FWIW: the Merc pumps aren't repopped.

Re: 8BA Type Water Pumps ID Car Truck or?
 

Thanks for that, so it would seem these are Merc. water pumps.
And must be different models as given measurements from casing to pulley centre vee are
2.3/4 " and 2" which is the same as to 8RT pump snout.

1950 and 1951 Mercury used narrow belt pulleys staggered like the 50-53 Ford cars, but with the high ear castings.

Not sure where I found this

Re: 8BA Type Water Pumps ID Car Truck or?
 

Hi 51, Were these pumps rebuilt by SKIP?? It looks
like the primer he uses. G.M.

Re: 8BA Type Water Pumps ID Car Truck or?
 

I have absolutely no idea, the pics. were gleaned off the internet and were represented as new pumps.

Re: 8BA Type Water Pumps ID Car Truck or?
 

Still wondering how these Merc water pumps have the high ear castings but different snout lengths. ie LHS: 2 3/4" longer one. RHS: 2" same as 8RT pumps.
Wanting to help out a guy here in NZ who has done some good for me.
Maybe to contact Mac Van Pelt as suggested.

Simple, they were designed for a Mercury passenger vehicle and not meant to fit anything else such as a Ford pickup truck.

Now maybe there may be a connection to the Canadian Mercury pickup truck, but I doubt it.

Re: 8BA Type Water Pumps ID Car Truck or?
 

FWIW Skip did 2 sets of OCM Merc pumps for me and as expected they are works of art. They do look like the photos posted but who knows for sure. Running one set on the 8ba in my '39 p/u and the other for spares but doubt I'll ever need them.

Re: 8BA Type Water Pumps ID Car Truck or?
 

The '49 MERC water pump snouts are both the same length because one belt drives the pumps and gen. and one belt drives just the fan.
The '50-'51 pass. side pump has a longer snout to accommodate the different belt configuration.

If you had a passenger side '49 Merc pump then the Merc. pumps could probably be used on a pickup using the same fan belt configuration.
Or put a drivers side pulley on the passenger side so that both pulleys are in the same plane.

Thank you so much for your supplied detailed information.
So I have a 49 and a 50-51 pump. i believe these pumps will be going on a 49 Jailbar. Info i can now pass on to the owner.
Again appreciate your assistance.

Just remember that if you use these instead of 8RT pumps, you will need a spacer to keep the engine at the same height. When I used these, I made the spacers out of 1/8" wall 2" square tubing and the worked fine.

Re: 8BA Type Water Pumps ID Car Truck or?
 

Yes Denny, these already have the spacers attached. My main coneren was to ID them and help out a guy who has helped me.
