My Hua Sheng F142 stopped durring a recent ride, it felt like it had ceased up, however it is well looked after and should not cease.
I dismantled the engine yesterday and was asked to display photos here of dismantling process.
Through the dismantling I was able to id problem, the problem is to do with component part 33 from the 142F Instruction Manual, the part is called a Shift Fork (pic 18 shows part in the manual).
I live on a farm and do regular mechanical work on a variety of machines, the component part 33 is to do with the bolts that clamp the Link Lever (Piston Arm) to the Crankshaft, which is called the Crank Case in the manual. Usual practise in clamping a Piston Arm to a Crankshaft is to use a lock washer that you bend up against clamp bolts to prevent them turning and comming out, I found no lock method used in this F142.
I can not see the use for part 33, it does not appear to interact with any other components of the engine and I have never seen it in other types of engines. If you recognise its use please let me know.
I will test engine today without part 33 and use a couple of spring washers on clamp.
