Modest progress on flywheel assembly. I and Mark ,my long suffering associate, have re-installed the points assembly, and determined that points appear to open at prescribed 5/32″ before TDC. We await delivery from UK of coil etc to determine that there really will be a spark.
Meanwhile, looking at the cutter bar, we are short of one Blade Pad -…[Read more] -

Many thanks to Andy and Kevin for their posts.
After great attempts I am sure that I will not be able to get the flywheel off the crankshaft.
Cutting it off with an angle grinder does not appeal, and would need a correct replacement and the need to set the timing
The plan is to take the remains of the brass wheel off the crankshaft (drill out the…[Read more] -

Hi Andy,
Here are a couple of photos of story so far. Visiting family have helped me dismantle the old boss which, as you can see from the photo, is still stuck on the crankshaft, and we now have prepared my ebay flywheel to replace it without disturbing the boss, and hence timing.The next phase is to reinstall the points and check the timing…[Read more]

Many thanks for yet more useful facts and suggestions. To Andy – yes you are right : my photo shows me holding the outer rim of the flywheel which I have cut away in an attempt to get better access to points and for heat. My post on Feb mentions this . The steel shaft of the f/wheel assy. is still siezed onto the crankshaft.
To Grahame:…[Read more] -

Many thanks to everyone for sharing their knowledge and experiences. I have now pretty well conceded that my flywheel assy is permanently seized onto the taper. I even resorted to cutting away the outer of the wheel to give me access for heat, and hopefully the contact points. For the next move, I have ordered an Ebay flywheel – not knowing if…[Read more]

Many thanks Andy for your post. A friend of a friend told me about the clever captive nut in the flywheel assembly, and I also found a S/H slogging spanner of the right size. The slogging hammer certainly shifts the nut – to the extent that in anticlock mode it seems to have stripped the thread of the nut &/or the crankshaft. Before running…[Read more]

Good evening from a new participant.
I have an Oxford Allen Scythe which worked OK about 14 years ago, but now seems to need magneto
refurb. Those in the know will understand that to remove the ign. coil I have to remove the Armature Plate. To do that I have to remove the flywheel assembly, and all efforts have so far failed. I’m thinking that…[Read more]
