(Japanese origin - manufactured in 1988)
For this you need to make an extractor, which you will attach to the flywheel in order to immobilize it. I offer you a listed photo of the tool that I thus produced:
To make this tool, I used a mild steel bar with a section of 20mm and a thickness of 4mm, minimum length of 145mm. Measure and mark on your bar a first line 25mm from the edge, then the second at 16.5mm, the third again at 16.5mm, and finally the last 80mm further.
Draw a line down the center of the bar along its length. This gives you your drilling axes.
The first (the one 25mm from the edge ... ) will be drilled at 6mm, the second at 5mm and tapped at 6-100, the third at 6mm and the last at 4mm.
To use the tool, it is not necessary to remove the 2 locking levers ( not visible here ... ) of the launcher. It is just more convenient to insert the socket on the flywheel retaining nut.
Install the completed tool on the flywheel, then turn the machine over and clamp the tool in a vise. Using a pin punch ( 6-7mm minimum ... ), strike a small sharp blow transversely to the clutch ( see photo). Attention, this is an English step, that is to say that the tightening direction is the reverse of that of clockwise! Unscrew the part, and pay attention to the needle cage bearing, take the opportunity to check that it is still in good condition ... When you reassemble the clutch, also tighten it using the pin punch.
Engine oil :
But where can this oil come from, you will tell me? Well, if we consider that this engine is of the 2-stroke type, and that it uses a mixture of SP95 gasoline dosed at 4% of synthetic oil " Special Motoculture engine 2T", also taking into account that the tank has a capacity of 600ml, that gives us a quantity of oil of 24ml. A part of course is burned with gasoline, but there is enough left for the lubrication of the crankshaft.
Chain oil :
For this oil, please, no frying oil! only use oil intended for this purpose, the name " Chainsaw chain oil"being clearly indicated on the cans ( which can be found in 2L and 5L ) in all DIY stores.
search When I was looking for spare parts, I had a bit of trouble because the Yvan Béal group stopped selling this machine. However, I managed to find the address of a workshop that could provide me with it. If this is also your case, you must send your request by email preferably to the following address:
