became popular with older mopeds and I could use one for local
transports in where I live. Furthermore I wanted a moped for rallies
nearby. First I bought a Zündapp and then it was time for a Puch. For
some time I followed the ads in a Swedish paper Blocket. The Puch model had to
be a Monza because it is 4 geared had a seat I liked and a carriage
carrier. There were several to chose, but I called one not so far away
from home. It was to
be find in a
village named Vretstorp. This place is situated som km west Örebro
along the high way. I had decided to go there and have a look. It was a
young boy named Kim together with his father, who showed me the moped.
It was late February so he had it in the basement. At first glance it
looked ok, it was just moved down in basement for the winter and it
was not cleaned. Supposedly, what I later realized that he had crashed
heavily. I could understand that, when I started to bring it in order.
For sure had had been a member of a local cross race in the village.
I wish Kim all the best in life.
Checking up the moped
Now I had the moped in my own garage and could in peace an quite check it over. I realized that I first had to wash it with my high pressure water cleaner. I had told Kim already when we were going to make the deal that if he in the future wants to get away from price lowering the stuff to be sold must look clean. This moped was not in that condition. The last thing he obviously had don was something like a cross competition in a dunghill because the moped was choked up with cow dung. See picture of what's left after cleaning with high pressure water. He had also made a heave fall because several spokes in the rear wheel were broken and the swing bars carried distinct scratches of this fall. The support had been torn away. All flashing indicators were broken and only the inner holders were left. The exhaust muffler was some kind of trim part and didn't fit the attachments. The seat had a fissure in one place. Most lamps were burnt out or cables had got loose. The chain was worn out and it was time to change pinions. Brake contact was not in order or was badly mounted. There was much work to do. A moped is a rather simple design and is easy to work with. The job is to make a list what to do and which spares I need. I could choose to call Puchverkstaden or Dangart. It became both. First parcel came from Dangart and I had supplement parts from Puchverkstaden. Then I had to put up a strategy for the work. I understood that the moped had to be fully stripped. This because a total cleaning and painting had to be done. The wheels must get new spokes and also for taking care of rust in the rims.
Buying spare parts and fixing the frame
Here all order lists with the parts I needed. It was expensive. If you make a click on this pictures you have an enlargement. More easy to see.
swing for the rear wheel didn't look nice. I dismantled it and bent the
arms as good as possibly, with the help of my vise and suitable tools.
The difficult thing is to get the long screw out. Normally it has got
rusted in it's outer bushings. Use copper hammer and you don't get later
Wheels, tires and front fork
Both rims were dismantled and the old worn out tires were changed. Where the holes for spoke there was rust could be seen. For this reason I took a steel brush and put it on a drilling machine cleaned it as much as possibly. After that I painted with zinc color and put on a new rim rubber band. It looked pretty good. Then I changes all bad spokes and added where they were missing. I started carefully just to now which corresponding holes it was for each spoke. This is a good advice when you only do things like this twice in your life. Only take away one spoke at the time and put in the new one. It is hard to remember spoke places. Then I had to control the front fork. It was in miserable stand. The covers hanged like a used condom. Steering bearing had a clear play. I was sighing. I had to start taking away front wheel fender and holder. Now I went this way. The fork was dismantled from the moped because everything must be brought in pieces anyway. Start to loose the 2 big nuts on the steering handle. Now the absorber system, 2 pieces, can be taken away. Put it on your bench. In order to bring away the lower part of the fork I had to use 2 screwdriver according to the picture just to get a nut away. But first you must use a hexagon cage to loose a nut from locking position. Then you put in the 2 screwdrivers. One for locking the nut and the other to screw the notch. Screw clockwise!! to get the nut away. Now you can bring out the lower part of the absorber. Take away the seeger ring and take out the inner parts. Now you have only the sliding part left. What's left now is the long spring. It will come out easily. In three places on the spring there are nylon washer for steering of the spring and stop the absorber oil to rush from one side to the other.
Take away the seeger spring, see picture, and bring out the parts inside the sliding pipe. We have a problem here because it is hard reassemble as long as the sealing is left. You must open the sealing an bring out the parts. Be carefully so you don't destroy the outer pipe. If not you must buy a new one. So far, all parts are loose.
Eventually you dropped some of the balls for steering bearing. You never find them. Change instead to a closed axial bearing and everything will be easier till next time. Change also all rubber sealer and o-rings. Now it is only to have fun and reassemble it all again. I have mentioned the locking device, but this you have to solve yourself.
Now its time to leave garage and go inside and kiss lover, have a vodka and go to bed.
To bring out the engine and update the clutch.
Now at last coming to the funny part, the engine. In order to bring
it out of the frame. Note that I have used the moped for some time in
order to locate if something is wrong. This was what I had to do.
The last things that I fixed.
last things I did was to change both chain gears and the chain. This job
take some time as one has to dismantle the rear wheel. I have tried
several different gearings. This with 11 is too low so I changed
to 13 and 50 for rear wheel. I also
cleaned the muffler and
had to change the insert.
