[6pack] Restoration, on a budget: heater

[Richard Lindsay]

Hi Friends,

   Another project recently completed was rebuilding the TR6's heater.
Here's how it looked, partially disassembled, and just as it came out of
the car.

   Now please keep in mind, a heater is needed in South Texas only as a
windscreen defogger on 1% of our winter days. That said (written?), the
heater still got restored.
   I first lubricated then tested the blower motor. It ran just fine so I
didn't disassemble it. It did get a little paint to protect a few bare
metal spots. No pix.
   The heater core cleaned up nicely. I flushed it clean then straightened
a few heating fins that had probably been there for 44 years. I also
gentlycleaned the exterior of the inlet and exit pipes on the soft wire
wheel. Here's how it looks reinstalled in the repainted case.

   Here's another look at the heater case, freshly repainted but with the
the Smiths label carefully preserved. Trimmed Post it notes make great
masking tape for these kinds of small fragile surfaces.

   And finally, here is a look at the assembled box with pipe insulation
holding the air direction flap closed while the glue cured on a new thin
(1/16") closed cell foam seal.

   With everything assembled with paint and glues dried, the blower was
tested again at both speeds. It blew air strongly through the core and ran
quietly.
