The current situation As can be seen the split is 52/48 in favour of the bigger side but still it refuses to leave
So far I have overheated my 4” angle grinder (but that was too big anyway); broken 2 Dremel bits; cooked my Dremel; blunted the hacksaw blade; and, damaged the tendons in my wrist when the Dremel got caught, stopped and kicked back as I tried to extract it pronto . But, I will not let the sprocket win.
Lucky you've decided to change is as it looks like you have a broken tooth at the bottom - that may have caused you some grief....
I’ve also been investigating hydraulic pullers however as they seem to work on the same basis as my regular puller I’m not sure it’ll do the job without inflicting damage. You may recall from an earlier episode the central bolt of the regular puller was just pushing its way into the threaded central hole on the gearbox output shaft and the socket was not budging. Somebody suggested to avoid damage to that threaded hole I put a metal plate across the end of the output shaft. I tried that. I used an old brake pad I’d taken out but, as you can see, the central bolt on the puller just embeds itself into it and starts to drill a hole This socket is one tough bugger I don’t even know why I’m taking it off, it’s not even worn. I guess that after being on there for 20 years I can’t leave it for the next owner Mind you, the way things are going I might just cover it up with the drive shaft cover and flog it on.
Just to confirm Paul, you did try the two opposing screwdrivers didn’t you? worst scenario would be bent blade at tip.
How about red-lining the engine and allowing centrifugal effect to eventually pull the two halves of the sprocket off the shaft? What could possibly go wrong?
If I knew how too I might. No broken teeth, that was me with the 4" angle grinder at the outset. Mind you I did set fire to the old t-shirt I was using to stop the sparks from damaging my freshly coated crankcase I did but to no avail, neither the tips bent nor the sprocket budged. If it weren't for the fact i'm keeping you lot entertained I would seriously park this issue, re-assemble the rest of the bike completely, strap on the old chain, insert the rear axle stand, take it up to 8k revs and drop the clutch. I reckon that would shock it off the output shaft
I was taking the Mick about the broken tooth You should've left the t-shirt to burn, the heat would have helped loosen the sprocket
