Hi All,
I have a replacement 100 amp alternator in hand and
have noticed it did not come with a pulley. I did not
expect this, but it is probably common. Naturally I
will remove the old pulley and put it on the
replacement unit. This brings me to my first question.
What is the proper torque for this pulley nut?
I have taken some quick measurements and find the shaft
diameter is 17mm, the nut that was provided is a 24mm and
is rather thin at only 8mm thick, which appers to me to be
a jam nut. I am sure that many are out there that have been
put on with an impact tool at who knows what amount of force.
I would prefer to do things right. Of course another issue
is how to lock the shaft in position while the torquing is
being done. I have looked and found that nothing that
looks suitable to securing the shaft from rotating while the
nut is torqued on, except a small internal spline in the
end of the shaft itself.
Can anyone offer torque specs for the other bolts that will
be removed and replaced in the process?
I have a Chiltons manual that covers this car and find it lacks
a lot of the details. it does have some step by step photos
showing that look like it will get me to where I can access
the alternator now in place.
Help much appreciated
