Back to my '93 Toyota/Warp 11" motor...

A clamshell motor mount looks like a quick & easy solution, but the stock
motor mounts are directly in line with the motor terminals :O Some nearby
plates would also make good mounts but they run right across the pole shoe
bolts...

Anyone see a problem with using the lifting hook holes for torque rods?
And just how beefy does the motor mount need to be?

Hello Adrian,

You can run a wide, about 5 inches wide clamp shell mounted right over the
top of the field pole mounting bolts. I welded in three rolls of curved 1/4
by 1/4 inch steel square rods under the clam shell which rises it above
these bolts. One rod on each edge and one in the middle which is position to
mess the bolt heads.

I had a steel yard cut me off a 5 inch piece of 10 gage steel tubing, which
I then cut into to clam shell pieces. I then welded on a 3/16 inch thick by
5 inch long by 1-1/4 wide flat steel straps on the ends of the clam shell,
with about a 3/4 inch space between the top and bottom flange, which is use
for bolting together using two bolts on each flange.

A Warp 11 motor is about 11-5/8 inch in diameter to the top of these bolts.
A 12 inch steel tubing is measure 12 inch OD, so it will read about 11-3/4
inch ID. When you cut it into two pieces, it may spring open a little, but
it will clamp down tight by making the edges of the clam shell flanges about
3/4 inch apart. I actually make the clamp shell tubing 1-1/4 shorter,
because when you weld on the 3/16 inch flanges, it will end up with a 3/4
gap.

I position the clam shell so it behind the front brush screen cover and dry
fit a standard GM motor mount in position in the EV to see where it would
attach on the clam shell and position near the frame. I then welded on a
3/4 in. thick, by 2 inch wide by 5 inch long steel bar on to the clam shell
that has 1/2 x 16 inch tapped bolt holes for mounting the engine mount.

You may have to design another type of plat form mounted. Some types use a
engine donut type that may work good.

Install the clam shell on the motor and bolt the engine mounts to it.
Position the motor and transmission in the vehicle to see where the bottom
platform of the engine mount was at. I then welded in a heavy 3/8 steel
plates to the frame with gusset supports for the engine mount to rest on.

Make sure the motor is level with reference to the differential, or both are
parallel to each other but not with the drive shaft. The drive shaft must
have at least a 2 degree minimum angle when the vehicle is resting on the
floor. Should not have the drive shaft parallel to the transmission of
differential, or the needle bearings in the drive shaft will not rotate and
will wear out faster.

I use a clamp on magnetic degree gage that you can get at a hardware store
to measure the degrees. If you floor is not level and if the vehicle is on
stands that is not level, that is ok. While the car is on grade before it
is jack up, measure the degree angle of the differential to the degree angle
of the bottom floor pan of the vehicle.

Then put the vehicle on stands and measure this differential reference
again. Sometimes a differential will drop down at a angle when its jack up.
Lets say it drop down 2 inches, so you know now that the differential should
be 2 inches higher. Take a straight edge with the degree meter attach to
it, to see what the differential degrees would be.

Lets say its 1 degree higher then, because the car is not setting level, so
now you make the motor 1 degree higher, so now you have the motor and
differential parallel to each other.
