One step ata atome..
I’ve done this a couple times over the 17 years I’ve been flying my 8.
Like others have said, take some pictures of how it’s routed from firewall up to governor, how the end attaches to the governor arm, bolt direction, washer placement, count threads showing…all that kind of stuff.
I then took that end off the governor and disassembled everything off the cable.
Undo all the adel clamps holding the cable housing and get it all the way oit where it’s basically pointing straight forward from the firewall. Disassemble firewall pass throughs.
In the cockpit on mine, I can see the jam nuts that lock the ends of the cables to the throttle, prop and mixture arms. I loosen the jam nut on the prop cable. Note the number of threads showing from the smooth part of the cable to the fork that goes over the are where the clevis pin goes through.
You can now use a drill attached to the inside, sliding part of the cable on the outside, and slowly unscrew the cable from the fork on the prop control arm. Just enough to get it apart from the fork.
For me, now comes the tedious part. (Where all the cussing happens) The two large nuts that lock the cable housing to the quadrant must now be removed. Tight but doable with your trusty self made, ground down, short mutilated ‘throttle cable wrench”. Here again, if you can, take pictures or count threads showing how many threads. . This should get you close when reinstalling the cable for adjustment. You then have to unscrew the lock nut closest to the quadrant. The nut will be captured because it’s over the still cable. Once you get the inside locknut loose, the forward one can be rotated usually by hand. Close quarters, but for me still easier than undoing the entire quadrant. Also for ease of installion when going back together, attach a string or safety wire to the end of the cable where it screwed into the fork to be used as a fish for pulling the new cable back inside the cockpit.
You’ll have to use all 3 hands and some salty language to unscrew the second locknut, slowly push the cable housing, feed the fish wire and holler at your helper outside who is very gently pulling on the cable housing to wiggle it out without pulling the fish wire off…… The wire will hold the jam nuts where they are needed when you do all this in reverse to put it all back together.
Reassemble in reverse, put bandaids on knuckles, pop a top and call it a day.
I’m sure there are other techniques, but this has worked for me.
