[TR] Was Smiths Heater Core Rebuilding/Now Maradyne Heaters

[Bill Brewer]

      Maradynes are aftermarket heaters designed for farm tractors or maybe a pickup truck. They almost slide straight in to where the original TR3 heater was.

     To make the Maradyne fit the TR3 better you need to disassemble it and reverse the heater core so the intake/exhaust is on the front of the heater and not the back. This way you can mount it flush against the battery box. I also cut out a notch to better clear the TR3 choke cable. Make the notch a lot bigger than you think it should be to avoid the choke cable having to bend. I used copper plumbing fittings from Lowes to reduce the fittings down to 3/8” rigid copper pipe which has a 0.5” OD to fit the TR3 heater hoses.

     I have seen Maradynes mounted to the trans tunnel, but I don’t like the look.

     I mounted my Maradyne to the back of the battery box using #10 SS sheet metal screws. I held it in place using double-sided tape while I was drilling the holes. I lined the bottom of the Maradyne even with the bottom of the battery box. You can barely see it under the dash. You can paint or upholster the heater to match your interior.

     The Maradyne seems to put out about 2 or 3 times as much heat as the original TR3 heater. Even with smooth defroster hoses I barely can get an ants fart to come out the defroster vents.

     They have two sizes of heaters. I would try to put in the bigger one (25,000 BTU) if possible.

     Good luck!

Bill;

Don't know the answer to your question but where does one get a Maradyne heater for their TR3? Do you know a part number? I've had my radiator cleaned and rebuilt but the heater core is in rough shape....

Thanks!!

     The heater core in my Triumph Renown is leaking. Does anyone know of a rebuilder for TR3-type Smiths heaters? I would go with a Maradyne heater like I have in my TR3, but it is very visible in the Renown and wouldn’t look right.

     TIA,
