| It
is now time to put the trimmed and lightened (see trimming
the motor-work history) motor plate back on the motor. |
 |
|
On
the motor's shaft there are three pieces that we need to be careful
with in our reassembling. The bearing (blue arrow) supports the
shaft and is supported by a pocket in the front cover. The threaded
backing plate (yellow arrow) keeps the bearing in position inside
the pocket. The shim (red arrow) makes sure the bearing is held
by the right tension when the backing plate is fully tightened.
The shim seems to be a different size in each motor to correct for
variations in manufacturing.

We
sever the head of a bolt and hand screw it into the backing plate.
The headless screw passes through the front motor plate and allows
us to pull the backing plate towards us while pushing the front
plate onto the motor. At the same time, we must be careful to make
sure the o-ring and water jacket seals are sitting correctly. We
dab a little blue locktite on the backing plate screws and start
them while holding the headless screw. Once they are started, we
remove the headless screw and replace it.

 |
|
The
eight torx head bolts get a little blue locktite and are screwed
in. We torque them to 18 foot/lbs in a star pattern.
|
 |
| Next
we bolt the front and rear adapter plates onto the motor. |
 |
| Putting
it all together |
|
We
lay a bed of 2 by 4's beneath where the motors will sit. We put
each motor in position and put in the front bolts (red arrows).
|
 |
|
The
front of the motor is now flush with the bottom of the frame. We
shim the rear of the motor to be flush also and then drill through
the rear adapter plate using the frame holes as guides. Two more
bolts and we can remove the 2 by 4's.

 |
|
And
the motors are in!
