All, Im attempting to install a 1948 59B Motor in a Stock 34 Ford Frame. Apparently I need 8RT Truck pumps to mount the engine. Does anyone have a picture of what a 8RT looks like, also a source for the pump or parts. Thanks HAMB.
8RT pumps have a flat mounting surface for the motor mount. airtex still makes these pumps, PN AW19 and AW20. they should be around $75 each.
I am not a Ford water pump authority, not do I play one on TV........but I am wondering if the 8RT pump fits the 59A engine, as the 8RT is the truck version of the 8BA 49' up p***enger car engine. Although the truck version came out first in the '48 F-1 Models. So far as I know, and I may be incorrect here, the stock 59A pumps have the same mounting "ears" as does the 8RT, utilizing the biscuit style mounting pads that set on top of the crossmember. '49 thru '51 Merc uses a similar style although the "ears" are at a different height (higher on the pump body) and are not suitable for '48 and earlier Ford/Merc ch***is'. What I don't know for sure is, what are the dimensions required for a '34 and how does that compare to the later pump mount spacing? It seems to me if an 8RT mounting ear 'works' on the '34, so should the stock 59A pumps. Having said all that, I used 8RT pumps on a '53 Merc Flathead in my '47 Ford to get the correct mount height but changed the pulleys to narrow belt style by pressing off the originals from the Merc pumps, and the new 8RT pumps and installing the mercs on the 8RT's. CAUTION..it requires a "fixture" to support the pulley inside, near the hub, or you will likely break the pulley casting when applying the pressure needed to remove the pulley from the shaft.
Well, that isn't the only way to do it. I ran a 59AB in my 34 coupe with a stock firewall and fan for years. It used standard 59AB water pumps (wide belt) and the only thing it had that you need to know about are 1.5" to 2" spacers that fit between the water pump ears and the rubber biscuit mounts that are stock. Back in the day, they made these kits -- (I'm going from memory here!) - the spacer was about a 3/8" to 1/2" strip of steel - about 1.5" wide that was bent in a 'U' with a hole drilled in each ear of the 'U' - one to pickup the bolt that goes through the rubber biscuit mount and the other that picks up the water pump ear. Here is a link to a standard style rubber biscuit kit: http://cgi.ebay.com/ebaymotors/Engi...r_Truck_Parts_Accessories?hash=item5ad4a30e15 When I got out to the garage today, I'll see if I can find the U-bend mounts (I have them someplace) - would be cool if you had a picture. Also, I'll do a brief check and see if anybody still makes/sells these kits.
Yes, these are the style adapters I have and this is also a picture of the pumps. This is the motor prior to rebuild. It came out of a 1936 Ford. I think Ill need a different pulley on the crank as well.
I thought '49 was the only year with the mounting ears parallel to the ground like the 8RT and the 59AB. I also thought '50 & '51 Merc the ears were at an an angle like the Fords but I guess I was wrong. Pic's of different styles here; thanks Mac: http://www.vanpeltsales.com/FH_web/FH_images/FH_other-pics/Flathead_37-53waterpumptypes.jpg Different Merc Mounts go here: http://www.vanpeltsales.com/FH_web/...s/Flathead_Engine_frontmounts_1949-52merc.jpg Jim
Those are standard 59AB pumps. You have exactly what you need for the setup (***uming you get some new pumps - by those I mean 59AB style). The only thing you'll need to change is the lower crank pulley - it cannot have the 'fan adapter' flange on the end of it - it will hit the stock cross-member. If you have access to a lathe, then you can cut the flange off, or just find the right single-groove, wide-belt pulley. Glad you posted back, now I don't need to go looking through cans and boxes to find them damn u-bends! Have a great day . . . you're on your way.
I have been told by my supplier in Australia that 8RT pumps are no longer made..seems strange to me..the last set I got from him were Airtex..so does anyone Know if this is true??
No to 8Rt...they are for '48-52 pickups, can be adapted but require other unneeded changes The pumps you have and want are available both new with better bearings or rebuilt old stuff...right legs and right pulley fit. You have '40 type pulley. The one you need is a bit rare, but can be duplicated by simply hacksawing off everything ahead of where the crank nut/ratchet secures it. You will likely make spacers, which can be solid or square tube bolted right to pump legs. '32-36 Ford biscuits go into stock places on frame...spacer will make a slight lateral move as well as raising. Proper height...put a rod through hand crank hole on spring securing thing and into center of the hand crank rathet on crank. That is the right height.
RetRod is correct and those B-17's kicked ****...go to speedwaymotors.com---they have what you need - new and improved 8rt's...
If you use 8rt's you will need to change all other parts on front of motor and modify the pumps as well...and even if gen pulley then clears the slanted radiator, a fan sure won't! Why would you lengthen the motor at substantial expense when you already have stuff that actually fits car and engine?? King Rollo shows the needed pumps (Ford 78 type, fits '37-48 and used on Ford replacement engines in '34's) and Airborne's pics show the original spacers and give enough info to start on fabricating a modern version.
