Sheet metal-made bottom cover fan shroud and installing it on the cover clutch tan that both parts are maximally aligned, connect them by screw MB. Through the holes of the casing cover Cernat in the lid of the clutch centers additional mounting holes, then remove both parts from the engine, drilled the missing holes in them and cut thread M5. Installing the clutch cover in place, screw it to the fan cover.
Now pass to the trunnion of the crankshaft. Putting on her gear Assembly with the impeller, the hub-shaped sleeve and a nut rigidly fixed it all together with a special bolt M8 placing it on a spring washer (in the drawing the latter is not shown) and bursting tightly shaped nut svincova the latter with the threaded section of the hub-sleeve.
The upper part of the fan shroud is cut from a sheet of tinplate, or roofing iron with a thickness of 0.3—0.5 mm. Bending the workpiece along the thin lines and by folding it inside the “reeds”, probailout seams and install the cover on the engine. As far as the holes in the cover under the candle and the mounting holes in the bottom cover, then obey them “in place”, during installation.
The intermediate shaft is assembled on the basis of the pedal from the bike. And the shaft (axis) it is better to re-carve of Steel 45. This in order to make it easier to spread on the one side of the timing pulley and on the other welded together stars vol. 2 and 7.b. But you can manage to do the latter and using the former (foot) shaft.
All the tubular elements of the power structure of the tiller, including removable arm made of segments of vedovato-wired pipe 0 ‘/2″. When bending the internal cavity is recommended to fill (to avoid cracks and breakage) sand. In winter you can do without sand, replacing it with water with subsequent freezing (into ice)— high quality and smoothness of the pipe bend guaranteed.
Fuel to the engine is supplied by gravity from the petrol tank (on a moped “Riga”) mounted on two tubular uprights welded to the hub of intermediate shaft.
The operation of the clutch and the throttle of the carburetor taken from the bike, cables from the scooter. To achieve more convenience (in use) behind the handle grip to the handrail drilled through hole 0 4 mm, which are inserted in the clamp fixing lever in the released position (when the engine is started). And implementation of removable handles makes it easy to place the tiller in the trunk of a car or in a sidecar.
In field trials (cultivation of potatoes) our Moto pomoshnik have shown enviable efficiency: the processing of fifteen acres took only one hour.
