Cobra jack warning

If you have a new Cobra trailer you may wish to inspect your tongue
jack. The handle is fixed to the worm stem by means of a roll pin.
If the roll pin comes out the handle falls off and the inside of the
jack, including the wheel, will fall out of the outer casing and
contact the road.

I recovered enough bits from the previous mile of roadway and added
bits from the local hardware store to get my jack working for the
contest. I'll probably have to replace the whole thing when I get
home.

I keep mine inside the trailer while on the road. Seen too many
damaged or destroyed wheels in the last 30 years of soaring to let it
happen to me.

Depending on the trailer tongue, it may be best to remove the jack/crank for
towing.
But on some older models, the hand brake machansim extends below and the
wheel can offer some protection.
They often tend to unwind when traveling.

After mine wiggled it's way down till the wheel was touching the
pavement, the tire melted and frazzled. My wife hated the original one
anyway, as she always got grease on herself when raising it, so I
replaced the entire assembly with a boat trailer tongue wheel, which
easily rotates 90 degrees for travel.

Cobra makes it so you can take it off while traveling. If you leave it on, its
your own fault, so you gets what you get, a bent rim, unrollable tire, or what
Andy got. Take it off and store it while traveling, I do. Oh, I did bend a rim
while leaving it on once, daaaaaaa never again. # 711.

I damaged the trailer jack a bunch of years ago when
it wound itself down while doing 65 mph. Since then
I just bungee it up while on the road and no problem.

I've never had a problem in 25 years of Komet and Cobra jacks (why am
I tempting fate by saying this????). I crank up the wheel with the
handle and tighten it...hard. I raise the jack post and secure that
handle...hard. It does provide some protection for the hand brake
mechanism that protrudes below the tongue on some trailers.

But that's if I do it. If I'm entrusting the task to my crew, I tell
them to just remove it and throw it in the van. Years ago my wife
tightened the retaining handle to her satisfaction but the jack
loosened and dropped. I replaced the melted wheel with a hardware
store version. According to her, the smoke from the dragging wheel
caused passing motorists, and her, to think the car was on fire.

Several people indicated the wisdom of removing the jack. All I
wanted to do was to alert people to the fact that it had a failure
mode that I had not anticipted.

I used a Minden fab trailer for over 15 years. The jack folded up in
about 2 seconds, cleared the road, and never fell down. The Cobra
trailer cost over half what I paid for my last trailer with gider
inside. I expected it to work and not to have to dismantle it before
I used it.

When I crank up the wheel, I run a short length of chain through the
wheel housing that is attached to the tow bar via a climber's quick
disconnect.
Removing the entire jack seems like an overkill.
