First post here on this rv.
Just got a '77 TM14. It's pretty much intact, but has no suspension travel at all. It was a _very_ rough right home. I've spent a couple days searching around including here and have not found any good info on what initial angle the torsion arms were set at. It's the first thing I'm going to have to fix and I'm expecting a call back after the inspection from a big trailer repair place tomorrow.
literature lists dry weight
around 1450; the axle
is spec'd at 1650. I'm going to try to get a 1600# axle
since I don't plan to load it up too much. But that given, I still need to spec the starting angle. "Standard" for this type of axle
seems to be 20D or so (22?), although the range can be from 45D to -10D.
What concerns me is that the existing torsion arms appear to be "resting" at -22D (all the way up, compressed), but when looking at the trailer from the side the tires
in the wheel well appear to be right where I would expect them to be - if the suspension were working right. IOW, my trailer appears similar to all/any of the photos I've seen of a Surfside
. If I'm understanding the situation, a standard 22D (positive) starting angle would lift my trailer by at least 3" and probably more. Now I don't automatically have a problem with that but it would put the tires
that much lower in the wheel well and on the face of it that does not appear to be what other trailers of this type have.
Does anybody have actual info on what the starting angle for a 1600# axle on this trailer is supposed to be?
Thanks for all thoughts.
