I am removing the Leece Neville alternator on the 86 with 8V92 . The alternator is mounted above the bell housing and drives off the blower . There are three bolts going through the alternator housing and spacer with cooling vents , threading into the drive housing. According to the Detroit manual the alternator should separate from the drive at the spacer . I have been unable to get it to budge there , however I can get about 3/8 inch movement between alt housing and spacer . There is white sealer between the spacer and drive housing , it's either stuck very well or I'm missing something here . I'm hoping someone out there can shed light on this or point me in the direction of a schematic . The manual that I downloaded doesn't have an illustration of the alternator mounting .
Any information very much appreciated .
Thanks,
Chris
