 Posted: Mon Jun 05, 2006 4:36 am Post subject: ADjustme of Wheel Camber on a FireFly |
 |
|
FireFlyer's
Since I bent a landing gear leg I have had ample opportunity to adjust wheel
camber. The straightened leg survived another landing on a rough grass
field, but camber was lost, and a new leg had to be installed. I found that
the original leg's OD that fit into the axle assembly was turned smaller
than the new leg. When I fit the new leg, I found that I had too much
camber in that the wheel leaned out much to much at the top.
I found my axle bender pipe and this time I took some photos. If you would
like to see how I made camber adjustments, they can be seen at:

Yesterday there was a fly-in breakfast at my home airport (I22). Rolled the
FireFly out and I had a fun morning talking to all ages. It is fun to be
around people who love to fly and love airplanes.

After installing replacement (not new) gear legs and gear/axle fittings on my early Firestar, both my camber and caster are incorrect... I used the existing mounting holes not realizing that apparently the holes are drilled by the installer, not Kolb and consequently, no two Kolbs will be alike... Now I need to move the gear up further in the socket and drill new holes...
Question is, what is the criteria for aligning the gear?... If a 5-6' 5/8" rod is slid in the axle sockets so that the axles are in alignment and then the mounting holes drilled, is that sufficient?...
Thanx...

That will do ok. Stick some weight in the airplane first because
angles change with
load. I prefer to locate the imaginary centerline of the plane on the
garage floor,
about 10' in front, then align a chalk line down the tire sidewall to
the corresponding
mark ten feet out. -Then drill either the hole fixing the leg in the
airframe
-or in the axle adapter. Perfectly parallel wheels will track just
fine.

Y'all;
A simple method that I use, is to slide a piece of tubing through one axle socket out through the other axle socket. A piece of rigid wall conduit works fine.
This will align the axles to the airframe.
Drill your mounting holes.
I always set camber at 7 degrees with the weight of the aircraft on the wheels.
When you set your skinny or fat butt in the aircraft you have about 0 to 2 degrees camber.
I always use 0 degrees toe in or toe out.

On the subject of gear legs, having straightened one so far in a
neighbor's
hydraulic press; Harbor Freight has a 12 ton hydraulic pipe bender for
$70
I got one last week for the next time I may need it. It has different
size
adapters for pipe size. I figure it can easily be adapted to use as a
regular
press too, for such duties as pushing piston pins, etc.

Thanx Jack and Jim...
I used a pickup truck bed partition, the tubular affair that you twist to
tighten against the sides of the bed, fortunately for me the ends are 5/8..
