Lister 6/1 Genset
Darren:
Yep John, sometimes just that little bit takes most of the effort :dremel:
Twin, sorry watsyaname?
Not my idea, I just adapted it from a commercial product I saw on tweb....I like to think I improved on it, well it worked anyways.
Stew,
No crack, in fact when it first moved I wasn't sure what was happening. Was the key moving or was the tooling bolts destroying themselves. At first I thought the latter, then realised the key was moving.
Gave me that nice warm feeling we get sometimes :D
Even so, it was still tough going, even when the key was fully out I had a job to get it off the crankshaft keyway as it was pretty stuck even in there.
Here's a picture of the underside of the key, as you can see it had rusted in two spots, but nothing you'd call heavy rusting.
The rest of the key is in remarkably good condition and judging by the paint it's original.
Here's the top of the key, note the oil groove. This one was showing, just. But on the other side, the other flywheel, the key is in much deeper....umm, wonder what joys await us there...... :bang:
Bernd:
Glad it worked for you Darren. Jack off screws do work when properly tightened. :ddb:
I'm sure those hubs need to be quite tough. Can you imagine hitting a pot hole in the road at 60MPH. That hub has to take quite a shock.
Hope the second side comes out for you as easy. :thumbup:

Darren,
It isn't an oil groove, it is a compression slot, to allow controlled deformation of the key. As the key is driven in, and it tightens against the other components, instead of putting excess pressure on the flywheel casting and maybe causing it to crack, the key metal deforms into that groove. Like an all metal safety valve.
Remember when I said earlier in the post about drilling into the key to relieve pressure, that is what the groove is doing, but in a very controlled way.
The other side should come out in just the same way. It only takes a couple of thou more on the depth of the slot in the shaft or keyway in the flywheel, and because of the angle, it will require it to be further into the slots before it locks the parts together.

Darren:
Thanks for the clarification on the slot John. That make real sense, I can see how that would work.... :thumbup:
SPiN Racing:
Thats fantastic!!!
I am really happy to see you got that guy out of there.
"SWMBO" as Rumpole and others would say... (I had to look it up.. and remembered watching that when younger) was asking me why the whoop in the kitchen.
I said Oh well Umm... ahh.... Well.
A friend got a really stuck part removed.. um.. yeah. :D
She gave me that look and said Oh cool good for him. :coffee:
It makes me crazy to have something like one of those nagging me, and not able to come out.
I work 3 days a week.. but I do nothing but work and sleep.. (And check the forum between times) and so cant pick away at things too easily.
Im really glad it worked out.
