ENGINE MOUNT INSTALLATION
.....
Make 4 EM2 backup plates. A full size drawing is included.
.....
Find the 4 Q2EM1 engine mount weldments. Use a AN6 bolt to stack
each Q2EM1 to one EM2. Next, drill in 4 0.190” diameter holes in each
Q2EM1/EM2 combination in the corners.
.....
Using the sketch entitled 'Engine Mount Holes', locate the four
hole locations on the firewall and drill in 0.375” diameter pilot
holes.
.....
Next, drill in the engine mounts on the firewall by taking each
Q2EM1 and using an AN6 bolt to stack the Q2EM1 to the firewall, and
then drilling the 4 0.19011 diameter holes per Q2EM1 through the
firewall. Temporarily mount the EM2 backup plate as shown using some
AN3 bolts so that the engine may be temporarily mounted on the
firewall.
PRELIMINARY ENGINE MOUNTING
.....
The purpose of this section is only to establish the size of
the cutout in the firewall to clear the magneto and starter
assemblies. Skip ahead to the section on “Magneto/Starter Box” to
understand what the final shape and size must look like. Then, open
up a hole in the firewall just large enough to clear everything.
During the next section, you will make the final hole. Once the hole
has been sized, remove the engine.
