RV taildraggers tow bar modification

[Ronald Sutton]

This modification to your tail wheel allows you to insert a tow bar into the tail wheel to ground handle the aircraft anywhere. See photos here:

I like the idea!

What is the pin dia. and the remaining wall thickness on the bolt? did you replace it with some tougher bolt?

Thanks

Why not just use a longer bolt with brass bushings?

That way you can use a Cessna towbar.

This tow bar has been around since 1968. I made it for myTailwind. I used it on my first RV4 and grossed it out at 1550 pounds to check the tow bar for strengh and control on slight grades. So far this tail wheel assy has 1560 hours on N112TT and 360 hours on N12079 plus five or six other RV's I made them for.

The tow bar I made will not slip off!

Nor will this one, even at 30 mph attached to my pickup truck

Good idea!
I was thinking about a self made tow bar and came up with a similar design like Dan´s. Then I was at Aircraft Spruce and saw different towbars and thought this one could work. So no cutting, welding and painting - bought one. I made an axle out of stainless steel to replace the AN6 bolt on the tailwheel and used two AN364-624A nuts on both ends. On the towbar I installed aluminum inserts to fit the axle extensions on both ends.

Dan, what did you do to extend the tailwheel shaft ?

Didn't. It's just the standard axle bolt.

I finally took pictures of the towbar for my -9.

Here is a picture of the tail wheel with the longer bolt and bushings:


Here is the Cessna ?Delux Tow Bar? attached to the tailwheel. Note, I turned the handle 90 degrees and drilled a hole for the pin.


Here is the reason for clocking the handle 90 degrees, my ?tug?:
