Jim -
I almost ordered one, and thought that the new clutch - which did set coil
side down for two days before install - would be good. But it was not.
I saw an earlier thread with the debate on larger/heavier/OEM versus more
blades/lighter/less power/more air/not OEM, and seemed to recall that the
severe duty clutch was the 'best' combo for the nylon fan.
Can I assume you've had good reports from the field on these?
I've changed several clutches on our '77, and this is the first out of box
clutch failure. Our fleet mechanic said they often fail if changed in
colder weather. He recommended baking them in the oven for an hour at 200
face down before installing. I can't imagine that the rich creamy silicone
center wouldn't warm up in 3 hours of driving.
The rubber flaps in front of the condenser are good on one side, but the
whole metal filler and flap is missing on the passenger side. So I have
some fabrication and work to do.
I'll get back to this after the holiday...
