Replacement Sprint Radiator Fan Motor

[archigator]

My original '71 Sprint radiator fan appears to have given up the ghost. I would like to maintain the original appearance for the Sprint fan setup and would like to find a replacement motor that would have a look similar to the original. I would also like to mount the replacement fan motor to the original "stand-off" frame that attaches to the radiator side wings, which requires that the fan have three-eared mount. Has anybody done this? (Was the original fan a Smiths or Lucas fan or something else altogether?)

At any rate, any help that you could offer would be much appreciated! Thank you.

If you are unsuccessful finding a replacement, since modern motors are probably smaller, you might consider gutting your old one and fitting a modern motor inside its shell.

Just an idea though, no idea how difficult that , might be.

Gary, have you taken it apart & tried to rebuild it. I have rebuilt 2 or 3, they are very simple... normal failure seems to be dried up bearings...

I believe that back in the day they used a standard smiths heater blower motor - available from these guys:

I bought one from them for my +2 heater refurb - it fitted, worked and looked original.....

Be careful... Sprints used a larger motor (same as Plus 2 130) with a 5/16" shaft.

Gary, I assume that you have a metal blade? - rather than the earlier nylon one.

I haven't tried to prise it apart, as I thought it was sealed and not able to be rebuilt. Since there doesn't appear to be a way to access the internals, how does one go about opening it up? I have the metal fan blade. Thanks.

Should just be 2 through bolts from back to front...

[richardcox_lotus]

Yep. I disassembled mine to repaint the casing.

Just some through bolts.

I have two flush bolts with no slotted screw heads and bolts don't appear to penetrate all the way through the motor, (No nut on the opposite fan side.)

I believe that these motors are readily available in the UK midlands at however the forum rules seem to preclude my saying just where!
Unlike those shown in the link that did get past the moderator they have the correct spindle diameter.

I have not seen a motor used like that before! There must be something on the blade face of the motor, you'll have to release the motor off the bracket & remove the fan blade to see.

Here is a picture of the two types of motor & blade usually used; Euro on the left (1/4" motor shaft) & Federal Sprints / later Plus2 on the right (5/16" motor shaft):
