One of the questions we pondered when I first mentioned this project
to my wife was "what will the neighbors think?"
Well, we never answered that question but whatever it is - they're
probably thinking it right about now...
I started out this weekend by removing the left side gear - here
is the jackstrut mount as viewed from inside.
A view that is only possible with a digital camera (unless you have
a head that's less than 3 inches in diameter)
Here's the left gear leg from inside the gearbox. It's mounted directly to the structure - no shackle on this side
Here's the right gear leg and that pesky shackle that won't budge
Yikes! the Oleo is coming out like a big ugly turd
Inside the filthy gearbox with everything removed except that stinkin' right gear leg and shackle
Bottoms Up
After the stress management therapy of last week and careful thought
- combined with a generous outpouring of helpful
advice from the folks on the Luscombe Digest I determined that the
only way to get those frozen bolts out is to use
horrid, brutal force. So I sprung the seven bucks for a "Handy-Hack"
with some extra blades and rolled up my sleeves
A new shackle was ordered from DLAHF along with new bushings
Okay... let's start here
The non-skid wrapped around the gear leg is to prevent the hacksaw
from scratching it
It's a slow, tedious process - luckily I have a lot of patience
There's less clearance on the forward end so I have to hack in the
up direction
this requires even MORE patience
1. jack RH of airplane to relieve load on RH gear
& drop to lowest point.
2. Remove gear farings.
3. Remove the nut and washer from the bolt that
mounts the shackle in the gearbox.
4. using a screwdriver or small chisel wedge
below the shackle bolt to create a gap 1/16 between the aluminum forging
and shackle.
4.A if unable to create a space, proceed with
caution so as to NOT damage the aluminum forging.
5. use a single hacksaw blade with handle
(not a frame)to cut the mounting 3/8" bolt. (if 4A applies, cut the
shackle also.
6. after cutting the front side, repeat
the process at the rear of the shackle.
7. Lift the leg and shackle through the
upper inspection hole to remove the shackle pin.
8. Remove the gear leg and shackle seperately.
9. using a hammer- tap out the cut pieces from
the aluminum forging.
10. replace the bushing, shackle, shackle
pin and lubricate generously with watterproof grease on assembly.
Here is the lower link section that I cut out. You can see how the bolt and shackle are, for all intents and purposes, fused
Of course this means that the outer sections of the link are also
still fused to the fwd and aft bolt sections that are still in there...
It's time to get "Midevil" with this sucker
You can't really tell from this picture but that's a triple cut
bit that will tear right through just about anything on Earth
After carefully grinding through the shackle - emphasis on the word
CAREFUL - I finally get it to let go of the bolt
The bolt end is still frozen in the mount bushing however. That's
another task for another day - one thing at a time
The rest of the weekend was spent organizing the shop
With the fuselage elevated on the stand there's room to work sub-projects
underneath - pretty neat
The little Luscombe can easily be worked in a standard sized two
car garage
Ask me how I know...
A mechanical work of art
My "locker art" Don't ask why I had a 100 pound drum of MSG
What else would one do with a bunch of old Maxim issues?
The bulletin board with a decidedly Luscombe leaning format these days
I haven't abandoned the polishing. Once the gear is all out I'll
be spraying some zinc chromate and some of the overspray
will inevitably get onto the fuselage so I've stopped polishing
for now while I concentrate on the mechanical stuff
Note:
I've tried to keep the website updated weekly and so far I've done a pretty good job. There's going to be a gap of a couple of weeks now though as my brother just retired and purchased a new Maule M7-235C. I will be assisting him in the task of getting it from Florida out here to California (the long way around) over the next two weeks.
Don't worry - I'll take some pictures...
