RE: (ET) Fw: Transmission Trouble

["Elie, Larry (L.D.)" <lelie ford com>]

E10's, even non-prototypes, are a bit different.  I have one (not yet
working) but as I 
understand it, there is no 'throttle' like there is on an E12 or E15; you
pick a speed 
and it goes.  This means there is ALREADY some tie from the gearbox to at
least the motor.  
I haven't dug into the schematic, but there is something already there.
Now, assuming 
that GE had problems with things like welded relays back in the 70's, I
would guess that 
they might have added electrically activated brakes to prevent such
occurrences.  Unfortunately, 
it is unlikely to locate the schematic for any prototype.  Bill Gunn has as
I recall several 
filing cabinets full of blueprints and schematics, but at last mention, 
they
were NOT in a 
organized state.  I suggest you give him a call-- but be prepared to make
your tractor a 
normal E10M instead.

Subject: (ET) Fw: Transmission Trouble


I finally got around to removing the transmission from the tractor
tonight and discovered that my E10 Prototype has an electrically
activated brake system that
had its wires cut for some unkown reason.
Does anyone have a description of how the electrically activated brakes
are supposed to work ?
Is there a parts list for the gearbox, rear axle or are there any
replacements available ?
I will not be taking the gearbox apart until atleast tomorrow night.
Should there be some markings on the gearbox indicating make, model,
manufacturer ???
Any words of wisdom on taking apart the transmission / rear axle ??
Thanks.

My 36 volt GE Electrak E10 Prototype decided to stop moving today.
The motor, all belts and pulleys turn, but the rear wheels refuse to
engage no matter what gear I use (reverse, low, drive-1, or drive-2).
Has anyone had this problem.
I suspect that something is wrong with the shifting mechanism in the
rear.
I am contemplating removing the entire rear axle, transmission, wheels in
one module and then investigate further.
Any words of wisdom would be appreciated.
Thanks.
