Here is what I did. In deference to nickster who
probably did a great job with the 60's motor mounts, I
used the stock mounts. Doing it didn't cause a strong
odor but definitely I would do it in a well ventilated
place it may be flammable but couldn't find any
warning. Sticky? Yes, but everything washes off with
acetone (from a paint store, and that is flammable.)
Supplies I used was duct tape, propane torch, and a moto
tool with a rough sanding drum. After blowing away the
rubber with the propane torch, I cleaned as much of the
rubber as I could with some alcohol (it softens the
rubber and makes it real easy scraping). Don't worry
about leaving some because the urethane sticks to the
rubber. Now that they are in two pieces, I decided the
place frame mounting bracket at the apex of the
U-shaped piece which mounts to the engine since the weight
of the engine is in a downward motion. Anyway, you
have to be aware of the distance between the bolt
mounting holes from side to side....this is very important
because it determines how tough it is to install. If you
are a little off however, don't worry since it is
flexible, It can be spread open or squeezed together easily
to fit the bolt holes.
First the piece which
bolts to the frame must be held in place. Then I held
it sideways poured one half of it, waited till it
dried and turned it around and poured the other half.
Then shaped it with the moto tool sanding
drum.
To hold frame mount in place: Drill a small hole in
the center of the plate which attaches to the engine.
I used a long but narrow toggle bolt screw. I used
the screw to push the frame mounts up against the
apex of the u-shaped piece. Again as you tighten it
down remember the bolt holes between the mounts have
to be a certain distance.
To set up the motor
mount: Use duct tape and tape one side of the motor
mount. Use a pencil to press in the tiny gaps. If you
don't the urethane will run through. Don't worry about
not being nicely shaped. The moto tool and rough
sanding drum will shape it. You should be able to prop it
up level on its side with small pieces of wood.
Remove the hold down screw and cover the hole with duct
tape when you do the other half.
The mixture: The
urethane comes in a quart size paint can and the catalyst
comes in a bottle. You have to split the mixtures in
half since you will be pouring it half at a time. I
got two quart size sealable food container from the
market for the urethane and two tiny ones to split the
catalyst. I used my wife's food scale to split the mixtures
exactly (by weight) in half. Store one half of it
airtight. Mix the other half real good. Wait about 5 to 10
minutes before pouring to harden it a bit. If you don't
it will run like water.
Let me know if you
need anymore information. It was fun. I alraeady have
it in the car and the vibration is no greater than
the stock mounts, as I can tell. The spark plugs are
much easier to get to. I recommend everyone to replace
your crushed motor mounts.....
