[TR] TR4 Fan Belt Replacement

[Alan Myers]

 Interesting idea, Geo, using a piece of rope! I'll have to give it a try
sometime.

There are also universal, emergency fan belts available, that you size as
needed and snap in place. But, like others, I just always kept a spare old
belt in the trunk. A rope might be handier for other things, too... such as
lashing down a piece of luggage on a rack, tying up the dog, or whatever.

I never had any clearance issues fitting the belt on my TR4. Never had to jack
up the engine or loosen the cross brace to install one, the way some others
say they've had to do. I've heard that if you have trouble mounting the belt,
it might be a sign that it's time to replace the engine mounts. But I wonder
if there was some variation in the positioning of the platforms that the
engine mounts sit on, welded onto the frame. (It might be a clue, on my car
the old air cleaners tended to rub slightly against the underside of the hood
under heavy engine torque.)

It's even easier to install a belt on it now, with a slim belt conversion
(mostly to simplify fitting an alternator) and the original fan/extension
completely replaced with a harmonic balancer and an electric fan.

Seems to be a problem unqiue to the TR4/4A.  I carry a length of
(nylon?) rope that is somewhat stretchy.  I have used it as an
emergency replacement and drove 100s of miles w/o a problem.  An added
bonus is that is can be used to just drive the water pump if the
generator grenades (what I had to do).

Just cinch it up real tight, use some boy-scout knot, then trim the
ends.  The rope I use is about 1/8 or 3/16 in diameter.
