Thanks Robert!
Its true and I think I found the ideal spot for where the motor could go!
Right next to the drive shaft to the rear differential. behind the
transfercase there is plenty of space on my CJ7!
The motor could be geared to the axis where the drive shaft connects this
way one would have the option to drive electrically with Transfercase or
gearbox in neutral, and one could even do electric 4WD!
Those Briggs and Straton etek motors or newer Perm(anent Magnet) 132 are
amazingly light and small at 8-15 HP.
I have to start make some spread sheets on torque from standstill, max speed
and potential range.
Of course I expect to find problems there... I know that most electric
conversions replace the motor and use the gear box to gear for torque or
speed as necessary!
This etek went for just over 300 bucks...

I think a very interesting idea, although not something I am considering
for
my Willys.
However, in a previous job I was working on using a stirling engine (close
to a hot-air engine) for use in a bus, so that explains my interest.
Disadvantage of connecting the electrical motor to either the front or
rear
axle is the added unsprung weight, and that the asymmetric weight of the
E-motor on the axle will cause the axle to rotate (leaf springs are
flexible
by the nature of the beast). And adding more weight to the axle will also
increase the tendency of the axle "to jump around the place" when the road
gets worse. For me it would be a NoNo to add any substantial weight
directly
to the axle.
But what about this? There may be another point to connect the E-motor to.
And that is the end of the transmission (of the T90). There you can
connect
an overdrive to, so an electrical motor should also be possible. The
E-motor
would always be spinning, but depending on the mode, it would act as a
generator to load the batteries, or as the engine driving the car alone or
even in combination with the gasoline engine. Extra boost! Extra
advantage:
the E-motor is not connected to the axle.
Stay in touch, very interested to hear where it will be going, and I am
sure
the Willys Gods will smile at the experiment.

?mne: [WT] Idea going round in my head... [Hybrid conversion]
Hey everybody!
I'm new to this list, just subscribed, and im happy to see how active this
group is!
With rising fuel prizes and all I have been thinking...
What if I removed the rear drive shaft and placed an electric motor there
Then I could drive on batteries for the short local hauls
and when I run down the battery I can simply lock the front hubs and
continue driving with the normal motor...
Anybody ever try that?
I have an 84 CJ7 with the 4.2l inline 6
