Hi nial,
That's real sad.
Nice looking machine though.
I have allways used the Peugeot Boxer, Citroen relay, and the Fiat Ducato van rear wheel 5 stud 150mm dia hubs on my 3.7m. All three van maufacturers use the same hubs and stub axial design. They are not that expensive New, and I search on fleebay etc.
Bearings... still allot of fake stuff so each new bearing gets the fine file test, gave one back to Timken recently that I could file, and it was not stainless steel.
The above van manufacturers are now using a single bearing instead of the 2 singles, so I modify my hubs with a spacer. see pic.
My No1 has been up 9 years now and is running fine, just needs it cable un plugging and unwinding about 24 turns each year.
My No 2 has a new fiberglass design HP blades on and is slightly heavier on the nose. This early design has water ingress on the plywood hubs and needs re-balancing every year. A few years ago it was just slightly out of balance, and to my cost, in a winter bad storm the tail jumped off its spigot, (the max furl stop bracket needs carefull attention when welding up as it has a tendency to force the tail assemble upwards), smacked the remains of a blade 200 meters away.
Next spring No 2 will get new hubs.
I now fit a bronze soft cord that will not allow the tail to lift up and away.
My mate Dimitri, just in the next village, has some fine Cedar for your blades, its taken him years to get some.
My No 3, up nearly 3 years, is running smoothly, and a No 4 is in production although a bit slow on that........
