The new ballerings, the new rod and the overdone flywheel getting back together. Rudolf than trued the flywheel to 0,01 mm which is much better than factory Defaults.

Pressing new plugs into the crankpin and than pressing the crankpin into the flywheel with copper paste. You need about 5 tons of pressure for this.

We polished the crankpin so the new bearings do not have to cut off material. The original bearings which consists of two parts rollers in each cage we replaced with “one-part only” bearings as you can see on a later picture.

You can see some marks on the left shaft of the flywheel. I gave it to a laser welding specialist who added some material. Later we took the material off again on the lathe and the result is a very nice and smooth shaft within the tolerances of a new shaft.

Here you can see how we pressed the crankpin from the flywheel and the oil dirt we found inside the crankpin after drilling out the plug. This is a typical 4-Stroke-Aermacchi problem and the reason you really should change the oil once a year or every 1000 miles. Rudolf decided the rod is used up and that I will need a new one.

While waiting for the paint job to be completed I have reproduced the gas tank decals as vinyl stickers. These are the 1971 design as I will go with the 1971 US design in sparkling green.

New tube and new tire, Heidenau K34 3.25-19

A lot of fresh grease and 50x new bearing balls (8854) for the NOS fork stem. The fork stem I got with the bike obviously got pressed together in the wrong way as the notch for the steering lock was on the wrong side.
The parts shown on the last picture like airfilter housing, kickstarer and some other stuff went out for rechroming that day.
