“What ever happened to TBM?” I’ve been getting this question a lot lately. I have hesitated to tell the truth because so many millions of men around the world look up to him —but the awful truth must come out.
TBM was vanquished by work. Yes, that killer of adventure, soiler of fantasy, shroud of exploration … sheer, overloading obligation. I tried valiantly to break away for a few days of tent camping in the cooler mountain elevations of northern Arizona, and some day trips, but again and again I was restrained at my desk by 1,001 projects that all needed attention.
Well, don’t feel too badly for TBM. I still ate out at a few favorite restaurants, watched a few guy movies, met some local friends, went to a car show, etc—so it wasn’t all bad. And to rationalize the situation, I resolved that in exchange for a late summer of Airstream travel (which we have since begun) it was a reasonable tradeoff to spend a few weeks in advance chained to a desk.
I also resolved that this won’t happen again if I can help it, so I’m cutting back on various obligations and hiring some more people to help. A new Associate Editor is taking off quite a bit of workload on the magazine, and I’m drastically reducing my involvement in events since they take a massive amount of time. (But don’t panic—Alumapalooza will be back in 2017!)
Back in New York at Colin Hyde’s shop, our Hensley hitch was being refurbished, and boy did that turn out to be an eye-opening experience. You might recall that we disassembled it and found many more worn parts and cracks than expected.
As Colin predicted, Hensley replaced the entire lower unit under the lifetime warranty rather than trying to repair it. When Colin’s shop got the unit back, they scuffed the paint and then repainted everything (top, bottom, bars, etc) with a really good automotive enamel so it will hold up better than the paint Hensley uses. (The orange in particular is famous for fading quickly and deteriorating.)
All the new parts were installed, and then of course we greased it, installed it, and adjusted it. It looks better than new now, which is good because the grand total for this job was more than half the price of a new one.
The eye-opening part was discovering all the parts that had failed without our knowledge. I knew the lower unit had cracked and suspected that the cadmium-plated steel bushings (“binoculars”) were also cracked. I didn’t know the extent of the cracking—and it was extensive—nor that the steel cylinders where the weight bars are inserted had stretched beyond repair.
The really shocking part was the bearings. There are eight of them in a Hensley, standard automotive-type bearings and races. You’d think that since they barely turn they wouldn’t wear. In fact the opposite seems to be true. Despite being packed with grease, all eight bearings and races were seriously rusted. It seems that the lack of spinning allows water to settle without being evaporated. The “dust caps” on the top and bottom aren’t waterproof, so water gets in and stays there, particularly on the bottom bearings where the dust caps actually trap water.
The picture says it all. Look at the rust on the bearings and the wear marks abraded into the races. These bearings were about six years old. All of them were bad.
The bearings are user-replaceable but the races are not. Colin’s guys found a way to remove the races, which involved welding little tangs on the races so they could be punched out, but for most people the solution will be to return the unit to Hensley under warranty. My recommendation to all owners now is to do five-year inspection and/or disassembly to check the state of these bearings, particularly in a wet climate. When you look at this picture, keep in mind that my trailer spends 8 months of the year in sunny dry Arizona.
The end of the story is simple. I flew back to Vermont in late July, reunited with my family, cleaned up and prepped the Airstream, installed the hitch, and we got on the road. (But in the midst of that, I did manage to sneak out two quick days of TBM activity: motorcycling north from the Lake Champlain islands, up the Richelieu River all the way to the St Lawrence through the beautiful French heart of Quebec.)
We’re now in the Airstream on a two month adventure that will take us from east coast to west, at least six national parks, and many interesting stops. So buckle up: the blog is about to get busy again.
