Subject:lube rear heater assembly

Hi,

I have a rear heater to replace the one that caught fire.  I do not want
this one to catch fire.  I'm wondering what people recommend for lubing
this thing.

Here are pictures:

Short version:  I have it out of the van, pre-install.  I am going to put
lubrication on the ends of the axles that you can see in the pictures.  I
would like list input on this plan.

Here's the result of my research on this:

I found descriptions in the archives of how to take it apart (this is for
the front one, I'm guessing you could adapt or use as-is for the back):

This is more than I want to get into, unless it's my only hope.

The fan that I bought turns with little effort but it does not keep
spinning if I am not pushing on it.

In the pictures (referring to my pictures, from the imgur link above

side.

From reading the archives, I see people recommending the ZOOM spout oiler

And there were also a few recommendations for Marvel Mystery Oil:

Sounds like the ZOOM stuff is made for exactly this kind of application.

Any thoughts?

I'm also thinking of doing the Mullendore port (
http://www.thesamba.com/vw/forum/viewtopic.php?t=386923) for the front
blower.  Can't remember if I lubed it when I had it out, and more lube
won't hurt.

One thing I would like to know from those that have worked on these is
whether I should expect the fan to keep turning if I give it a push, or if
it's normal that it requires continuous force to keep it moving.  That
could at least give me some information on whether the lube is doing
anything.

I really appreciate you guys and all the wisdom you've dispensed over the
years.
