"TO STRETCH OR NOT TO STRETCH " a frame the correc

Question:
Am looking at buying a car with a stretched frame. Have'nt inspected it yet or seen how it was done. I do know the stretch was done midway between the cab and sleeper aprox 30". What is the proper/ improper way to stretch a frame and what should I be keeping my eyes open for concerning possible problems?. Would also like to know the names & locations of any shops that do this type of work.
Any input would be apreciated.

Answer:

Look for high quality welds, double plated framing, and a well bolted structure. Everything needs to be in good alignment, and just as a general rule I was taught, the stretch joints should be in the most non load bearing part of the structure possible. If the joints are under the sleeper and cab, sounds like it was done competently if the quality of the work looks properly well done. My 02.

Answer:

Tnx for the imput Burky. Would rather be safe than sorry.

Answer:

Let me also point something that's real obvious. There are plenty of cars running around out there that don't have stretched frames, so with a little bit more time and effort, you may well be able to find one where this isn't a concern. Don't be afraid to expand your search outside of your home area and look further. Set your specs and if it doesn't feel right, move on to the next car.

Answer:


TNX fer the input. Been looking at various inet-trkng sites for several wks, talked as well as looked at numerous rigs nationwide. One thing I know by experience (20 plus yrs) is do the research before buying. Also Burky, how far should the add on extension overlap the factory frame?
Tnx

Answer:

I was always taught that a frame splice should be at least 3 foot long, or 18 inches on either side of the joint. Depending on the length of the stretch, if at all possible, the inner frame should be long enough to cover the entire amount of the lengthening with one piece of steel. It isn't done so much in commercial caring except when putting on big aftermarket sleepers, but stretching a frame is really common in agriculture where a tractor will be converted to a heavy duty straight grain car. But again, if you don't have to have a stretched frame, it's one less thing to worry about on a car.

Answer:

The frame on my T800 was stretched 24" between the sleeper and the drives. Single frame only. It was done at a well known shop that specailized and welds were Xrayed . Noo fish plting required.
A weld should be stronger than the metal that it's holding together.

Answer:


Excellent advice.
One thing that would concern me about welding a car frame is that so-called special high strength steel is often involved (at least that's what the warning labels on most new car frames indicate). The bottom line correct proceedure would lie in whatever advice provided by the people that actually manufactured the frame.
