[C38] Alternators

Thanks for the input Tom T, as always it is appreciated.  I have seen "kits"
out there for just this project but they are very expensive.  I'll probably
wait until my Rich Uncle gets out of the Poor House to do this.  LOL  Oh the
other hand though, it does look like something I will strongly consider.
Take a look at this:

and let me and the list know your opinion please. 






Best regards,

Hello Larry and group,

I am retired from the automobile business and was a technician (mechanic) in
my earlier years.

When the serpentine belts first became popular on cars, they drove us crazy
with squealing problems.  Unlike a v-belt, a serpentine must be have perfect
alignment from all pulleys. The car makers were used to getting it close
with v-belts but close was not good enough when it came to the serpentine
belts.

We had factory recalls using shim kits to move various components of the
system so the belts would line up right correctly.  A v-belt is extremely
forgiving but not so with the serpentine.

That being said, as you know there is no comparison in efficiency using a
serpentine belt and I see your argument for a conversion to serpentine. 
There is very little horsepower waste with a serpentine belt where a v-belt
robs a lot of horsepower.

I think your idea of a conversion to serpentine would be a great benefit but
at what expense?  If there was already a kit on the market to replace the
pulleys and also shim the components for perfect alignment it may make a
good project but going it alone may be more of a project than can be
justified.  I expect you would have to fabricate the pulleys from welding
serpentine rims to the existing pulleys, etc.,  making this endeavor more of
a career than a project.  Keeping the existing pulley ratios would also
complicate the procedure.

If Kabota uses serpentine belts on their current crop of tractor engines and
the pulleys would fit your engine and components, your project just may be
feasible, but again, at what expense?  The reference it Kabota is assuming
you are using a Universal engine.  Any other engine would present the same
logistics for pulley replacement.

Anyway, that is my opinion.  I am always a fool for jumping into this type
of project but thankfully I sold my boat or I would be trying to figure out
how to make this worthwhile upgrade.  I have a simple machine shop and weld
shop but having these capabilities and equipment can be a curse.  Smarter
people than me know when to say no or they pay someone else to do the dirty
work but I was never that smart.
