But then you make friends with it, the glue has become brittle, parts falling off. Needs treatment. Action must be taken. The merciful doctor killed the patient.
Since those engines have practically never turned, let's see if they still work:
The grease has become a sticky clay. A couple of suspension wheels have play. We clean everything
We apply molybdenum grease:
We isolate the transmission compartment:
Let's move on to the rolling train.
Each wheel is opened, cleaned, reassembled. The metal couplings are blocked with a drop of medium loctite (with the heat gun you can go back). In place of the Phillips head screws, cylindrical-head screws with hexagon socket are installed in the visible points.
Each element is locked with loctite 222.
Transmission area isolation completed
Reinforcement on the crack
Suspension wheels ready to be re-loaded
Removed the two sheets of diamond plate, they were unlikely. You could see for a kilometer that they were stuck together
We remove this or leave it
???
We begin to reassemble the trolleys and ...
The flaps of two trolleys split apart as I pulled the bolt over. I put everything away this morning and I start to understand why:

[/url]Third break ... In practice, the spring that creates the suspension opens the fins. Sometimes the material resists, you can see the cap that goes in effortlessly:
On the other hand, when he strains, he puts pressure on them and breaks them. I start to disassemble:
There is no shortage of surprises. But let's continue with the other carts:
Another break
Another break
Every three parts you take apart you find two broken. The material did not hold up to the springs. Too weak ..
Yesterday I ordered the canted arms, the ones where the lugs are. They cost € 3 per couple. € 9 for spare parts and € 20 for shipping.
With today's news I wrote to Asiaam if by chance they also have horizontal arms.
If they are not available, I see no other solution than ordering the entire rolling train.
Horizontal arm:
This Chinese crap really broke my browns.
Positive news first:
The result was obtained by gluing on the metal the net used for the naval to make the sails of the boats with cyanoacrylate. It is a very light tulle. Then we moved on to the painting of the mudguards and then to their sanding. The effect is satisfactory in my opinion.
It is not a pure diamond but to the eye it is much more satisfying than smooth sheet metal.
The part of the mudguard that has an imperfect finish will be covered by the zimmerit and I expect to have a realistic result in the end.
Subsequently installed the IBU, the new trolleys arrived from Asiaam and were installed. We had the tracks stretched and you could see that something was wrong:
The other G. Box:
The toothed wheel has an axis which is pressed into the hole made in the sheet:
Oh well 40 years ago they built like this. We accept it. At this point, take the repair drawing (approved by the technical area) and off you go to get the materials.
Obviously the repair will also be applied to the other side
Very unworthy. Treatment:
The unthreaded portion of a bolt acts as the shaft on which the brass gear idles. The threaded stem was naturally shortened after installation.
The bolt head had to be reworked: the hull wall is damn close to the Gear Box:
The change has also been applied to the other Gear Box. Fortunately, the slot on the hull allows an inclination such as to insert the two Gear Boxes complete with drive shafts:
While we were with the engines in hand we improved the isolation of the positives that went dangerously and easily to mass.
On this installation:
We would have liked to put a bumper. Unfortunately it is not possible:
From the left the bearing cannot pass (there is the toothed wheel) neither from the right (there is the hexagon that engages the drive wheel). So let's make peace with our conscience by installing the cover that covers the hollow from the eyes:
All that remains is to re-embark the tracks:
Excessively fast for my taste (it's a self-propelled not a rodeo rooster) I really like how it calibrates the movements at low speeds. Nice movement of the carriages, correct track tension.
Next test: off-road and the inclined plane ...
