Wedge Heaters again
Discussion
This the plastic version, the metal part as such bolts on so it can be handed...Smiths FHB 5402/24 (212) obviously (or not) the hamster wheel fitted to the Smith's fan generically and on Leyland cars it is rotationally colour coded, but today they are all black...Phil, I need to take some more pictures with mm displayed. 
A lot of the wedges (mine included) don't actually have a fresh air intake, it's effectively a cabin recirculator.
Early Tasmins did have an orifice in the heater box (or rather the firewall mounted cover) top face that coupled to the mesh vents in the bonnet but certainly on the car I had (chassis 36) no matter how you tried to seal it, it still pulled engine bay fumes in.

...i do plan to seal it with an air filter eventually, once i have upgraded the blower motor in the interior fan, at present its like a mouse with extreme flatulence, wouldnt even blow out a birthday candle..Mark, this is why I talk about the hamster wheel...IF the motor has been changed (three screws) in the past, and they swap in the wrong directional one it simply thrashes at the air rather than pumping. It is as near as impossible to take a wheel off as you damage them, but they are now readily available to buy (they weren't). I have a few motors that I can offer in the casing to try to work out the flow, using different wheels (assuming I have both versions)...over the next few days. (It is common to see this on the Vixen/M Series cars as they get mounted in 3 different ways across the models and again, that applies to Tasmin twin fan versions). A@

Hi AdrianWould you know if the motors are available as i did a search with the numbers you supplied but nothing seem to cross reference..i was even contemplating getting mine rewound/refurbed...are you talking about the plastic hamster wheel breaking as i have seen those for sale as you say?
Cheers

Mark, my number was for the snail part. As that plastic version is a RH/LH version (metal snails are not). The Smiths motor is a FHM number... Without pulling my car apart I could not get a number related to the single fan 280DH I have. You will see that they have a decal denoting rotation. A@

The snail appears to be mounted using old school wiper motor bobbins (I presume to isolate it from the shell). A@

Thanks AdrianI might have a couple of options, car builders sell one that might work and i found some others, although i do not have any dimensions yet for either old unit or fitting..

Something will work, i have seen the motors for sale as well but splitting the unit might just be opening a can of worms..

Smith fan run bearings and they squeal then they naff to play with, I rewind motors and have never done one yet. I have just refreshed one for my turbo FHM 1203/02, the motor as such is not directional, so you simple change the +-, it's 3 screws to swap another motor with the wrong hamster IF I have one. (I have to strip down 4 TCar hubs today, so I will look tomorrow. A@... This is the steel snail from my Taimar turbo. 
Mark, here goes ...my thoughts are that on my 280DH, my single drivers side fan would be rotationally correct as a yellow hamster wheel (from the back it rotates clockwise) and pumps into the side of the box 
I have replaced my wheel with a NOS motor and broke the wheel trying to change it SO, it is rotationally correct but black. (the white wheel would pump through the snail on the opposite side twin entry box).A@
Mark, when you're looking at the picture, you can see I have broken the wheels on those two motors. I did spin up both in a snail (they are out of balance) AND that will still be an issue when a new wheel is installed, it took me ages to get the harmonics sorted by removing a clip from and old wheel from blade to blade). On the metal snail they install the ballast resistor in the air flow, on wedges they run either a ceramic ballast or a Ford blue resistor wire to control 1/2 speed. A@
