Solenoid Summer II


Overheard in the kitchen:

Hayley: "My dad is wearing that black shirt you didn't want. Barbara shortened the sleeves to make it a short-sleeved shirt."

Chairman: "Glad he's found a new lease of life for it."

Hayley: "She also took the swastika off."

Disaster with the Allen Scythe. Tried to remove the flywheel in order to get at the solenoid and managed to unimprison the captive nut that held it on. Apparently (after looking for a relevant YouTube video) one is meant to give the ratchet spanner a few taps with a hammer after the first half turn in order to release the flywheel assembly from the tapered spline and then continue to unscrew it, but I just continued to unscrew it with an extension on the ratchet, as it was very stiff.



The silvered area at the end of the nut is where it came detached. I now have a 'spares or repair' item for eBay.

I did request assistance from someone in-the-know on a farming forum, but all I got back were commiserations from people who had suffered a similar fate when trying to remove the flywheel.

If I could somehow get the flywheel off then there's a good chance of reattaching the captive nut, but getting the damned thing off the tapered spline seems impossible. There must be a way though and I'm not going to give up just yet. If simply unscrewing a captive nut eases it off, something must be able to ease it off, although levering with screwdrivers has no discernible effect.

Any suggestions?

You won't prize it off, it needs a sharp shock. Can you place a drift into the hole vacated by the captive nut and give it a couple of sharp taps with hammer?

i.e "fetch an 'ammer to it"

Geoff - I did. No effect.
