Hi all, been a bit distracted of late doing up a 5ta I got, but fired up the D1 for the first time since engine rebuild. Lovely! I'd been unable to get the !#$×!! thing to start and it appears it was a dodgy float. So i bit the bullet and shelled out 25 quid for one of the Czech repro ones. Did the trick nicely.

Next day I was tottering about with the timing and stator plate and inadvertently removed and dismantled the entire front end. Isn't amazing how often that kinda just *happens*

Anyway, dismantled it all, ordered a few bushes and rubbers, and while I was chasing the threads on the fork spring top scrolls, I chased z bit too much and now can't get the scroll back up in one of them. Can't even get a pair of long-nosed pliers on the little blighted which is stuck solid.

Any suggestions would be more than gratefully received. BTW, I own neither a vice nor an oxyacetylene burner 😨

Cheers

how did you drive the scroll in ? A  little epoxy on the nut.. wait a while and reverse? Most epoxy will come off  in a gas flame.

the lad has suggested finding another nut but filing it undersize to permit a box spanner to pass over it.then as the lower nut unwinds it should stop..much the same as removing a stud.

Thanks john. Good suggestions. Will try them out. Was chasing the threads and one scroll worked its way below the spring coil. Very odd 😈

It is a Bantam it is called charm...I am a bit puzzled as to how you drove the scroll ..

The springs often have to be hammer and punched off the scrolls, I wish you well with the job and hope you find a way to overcome it.

It often seems that trying to unscrew the springs just tightens them up, whereas they always seem to go on so easily, as a general rule.

Keep us informed, please.

Four now on the road and at least several in bits.

further thought from Wallace and Grommit here...get a snug fitting long socket on a long extension hard up against the dome of the scroll and wallop the spring...Christmas is coming put good vice at top of list.

Im damned if I know  how it went so far. I was using a ring spanner so couldn't have wrenched it that far.  Oddly, whether i turned clockwise or anticlockwise the scroll went inwards. Perhaps some elastic tension/torsion effect of the spring?Curious. That is despite the hefty thread on the scroll which will make drifting harder. That is once i get access to the scroll base to give it a judicial wallop! I may have to drill into the top of the scroll and use a screw extractor to remove it. Proper bleeding nuisance.

will it simply go all the way to the bottom and fall out....the lad says if you can put some extension on the spring it may unlock enough to either do that or unwind

@ well-cheesed-off.com!! Spring came off bottom retainer nice 'n' easy. However, the scroll cannot be moved at all and withba combination of drifting, extending, twisting, poking and cursing, the spring around the stuck scroll has now kinked. So I'm resigned to shelling out for new springs and probably new scrolls. Merry !#% ¥*!& Xmas to me! I think your right Mags, it doesnt matter which way you turn the scroll, it goes deeper in. Oh well, lesson learned. If it ain't broke, DONT fix it! - well, til the next time 😨

Thanks for all the suggestions, guys.

Do they still make Dewar's?. Probably rebranded and promoted by some teetotal celeb. Best used for cleaning out a dirty old petrol tank ☺

Those springs look good, John. Yeh, I'll cut the offending scroll out. What a bleeding nuisance! !
