Paul,
   The ELAST belt does get re tensioned once at 6,000 miles and replaced at
36,000
The previous pulley SI Bulletin (#2747) I mentioned, replaced the pulleys
and installed a new belt.  The Upper pulley was changed from
Aluminum to Steel.  All Oilheads AFTER 09/1994 had this change
installed at production.  It was NOT a Service Action item and was
Service Information only.
