8. Locate your motor and we will begin the mounting process, 1.125” standoffs
will work perfectly for the DA120. If you are using a different motor then plan
on needing 7.25" from the firewall to the front of the cowling, you may want
toadd 1/8" for spinner backplate to front of the cowling clearnance/spacing
for an overall distance of 7.375”.
I will focus on the DA120, this motor is 6.25” overall so I used 1.125”
standoffs to yield my desired spacing. You could use more or even less, but I
recommend about .125” of spinner backplate clearance. You will need to use
¼” allen head bolts of about 2” to 2.5” length, depending on the amount of
threads you want exposed on the inside of the firewall. I also recommend
nylon inserts nuts, with washers and red thread lock for mounting the motor.
Once you have mounted the motor, you may install your desired exhaust
system at your discretion, however I recommend following step 9 before any
exhaust is installed. See figures 14 & 15.
