alternator for 89PT40

[mbulriss]

Gus,

I know it's real tight back there, but I really wouldn't think it is
so tight that you need to remove the bumper and frame end cap. I just
had to be patient and 'finesse' them a little until they slipped on
by. If needed, some real soapy water and a long dowel or blunt
screwdriver might help sliding them around the front of the pulley and
through the tight space in front of the pulley. Perhaps a hand above
holding them steady while you attack them from below might help also?

alternators today. It was not that bad. While I was down there I
decided to clean all points of contact as Mike sugested, including the
starter. I had them tested at the alternator shop and was told that
one was producing 50 amps and the other one was producing 60 amps. I
decided to replace them both with new ones by Leece-Neville 110-555JHO
160 amps. Everything was going well. I was even ahead of schedule
untill I tried to remove the belts off the engine pulley in the back.
I can't for the life of me squeeze them through the small gap between
the pulley and a plate. I can't see down there but I can feel a small
gap with my fingers. It's just not big enough to slip the belts through.

appears that I have to remove the back bumper and the back plate
that's attached to the frame. Then I will be able to see the pulley on
the engine. I'm hoping there's another way. I would really like to
put new belts back there. Suggestions appreciated.
