Replacement for a Cobra Tongue
Hi everyone,
Upon my return home from Cordele I was shocked when I saw that the tongue of the trailer had almost completely cracked off. Luckily I noticed the crack while I was hooking up the trailer to tow the glider from home to the airfield. The crack is just ahead of the hand brake mechanism. I know other people have experienced simillar problems, are there any other options apart from ordering replacement parts from Europe? Luke |

Replacement for a Cobra Tongue
Why did the tongue crack and why there? I don't wish to start the
great tongue debate again, but its my firm belief that the hand brake hits when entering or exiting gas stations and that leaves the weight of the tow vehicle pulling down on the toungue. What type tow vehicle do you have, motor-homes with long overhangs are particularly susceptible.

The only explanation that makes sense to me is what you describe, the bottom of hand brake mount bottoming out and creating stress on the tongue just ahead of the weld for the hard point. |

I'm afraid JJ's wish won't come true! Why do you and JJ think a crack is started by compressive forces? If the problem is the tow vehicle pulling down on the tongue, shouldn't we expect the crack to be on top? The placement of the crack at a weld suggests fatigue cracking caused by upward forces on the tongue. How many miles does the trailer have behind the Honda? How many miles behind what other types of vehicles? If the Honda is theonly vehicle used to tow it, and the trailer has less than, say, 40,000 miles, I'd suspect a defective tongue. Perhaps the weld was improperly done. In any case, start out by contacting the trailer manufacturer for an explanation and a recommended cure. You might even be offered a replacement at a very good price, as some manufacturers really stand behind their products. -- Eric Greenwell - Washington State, USA * Change "netto" to "net" to email me directly * Updated!

I am not pointing the finger at anyone I am simply trying to explore all options. This is a used trailer that has traveled many thousands of miles (i don't have the exact details) so some wear and tear is to be expected. Best Regards Luke |

I drive a 2000 Honda Accord, a 4 door sedan. The only explanation that makes sense to me is what you describe, the bottom of hand brake mount bottoming out and creating stress on the tongue just ahead of the weld for the hard point. In attempts to keep the tail of the trailer from dragging in every service station, etc, some use a tow hitch which is too low. This causes dragging of the tongue, which can do more damage. Agnes Spindelberger is shipping a "lift kit" to me for a 1994 trailer. It will mount between the axle and the body of the trailer to lift the lot 50mm / 2". I will then use a 2" higher trailer hitch, and the whole trailer will have greater ground clearance. Having owned another (1985) Cobra with a lift kit I found rigging from the raised trailer, still connected to the car, is not a problem. In that case the lift kit was a 2" square steel tube between axle and trailer body. The suggestion is NOT trying to resolve the problem of dragging the trailer's tail by lowering the nose. Jim |

Replacement for a Cobra Tongue
In the mean time try (i know that it is not always possible) to enter
crevaces and depressions into gas stations or other areas by going at them in a 45 degree angle or or lower from perpendicular, This will allow only one tire at a time from lowering the tongue or trailer or tail and prevent most scraping. I realize that most motor homes are very long and makes this a challenging feat. I have taught my crew to give up the .02 cents per gallon (after all whats 1.20 on 60 gallons) to go to a gas station with alittle more room for manuvering.
