wayne_weedon Posted November 21, 2009 Author Report Share Posted November 21, 2009 (edited) Made up an adapter to use a Hydraulic 10 ton puller to extract the primary flywheel. Worked a treat and no heating required. I think is was less than 10 seconds after fitting that the flywheel popped off. But with a fair crack! Got to love those hydraulic pullers! Wayne....

b40rt Posted November 22, 2009 Report Share Posted November 22, 2009 (edited) Must as santa for a 10 ton puller. Edited November 22, 2009 by B40RT Quote Link to comment Share on other sites More sharing options...
wayne_weedon Posted November 22, 2009 Author Report Share Posted November 22, 2009 They are good Ross. But can be clumsy. The normal legs would not go behind the flywheel. But it was tapped for 3 m10 bolts, so I used them. Maybe overkill on the strength of the adapter, but it's done now. The rebuild proper can start now anyway. Wayne...

wayne_weedon Posted November 22, 2009 Author Report Share Posted November 22, 2009 (edited) This is the main reason the bike was just put away all those years ago without being tried and the reason the engine HAS to be rebuilt. As you can see the previous owner attacked the final drive sprocket with an angle grinder, but kind of went a bit too far! I seem to recall there was some Devcon stuck to it which of course just fell off when prodded. I'll probably gently build up the shaft with weld and regrind the taper. Although the part number is very similar to the 348/9 It's not the same part I'm sure. 330 has a different kickstart mechanism with an idler mounted on the end of the problem shaft. So the shaft is longer than the 348/9. Wayne.... Edited November 22, 2009 by wayne_weedon Quote Link to comment Share on other sites More sharing options...
steve Posted November 22, 2009 Report Share Posted November 22, 2009 Ouch, now that shaft is nasty. Looks like they used a Stihl saw !! Quote Link to comment Share on other sites More sharing options...
wayne_weedon Posted November 22, 2009 Author Report Share Posted November 22, 2009 Ouch, now that shaft is nasty. Looks like they used a Stihl saw !! Haha but at least there was the new talon sprocket they intended to fit in the box of parts. No consolation of course as the damage had been done. Looking like I'll have to repair that shaft or make a new one. Not likely to find an original part now. Wayne.... Quote Link to comment Share on other sites More sharing options...
steve Posted November 22, 2009 Report Share Posted November 22, 2009 I suppose the risk with weld is that it might pull the shaft. You've nothing to lose by trying though. If it does bend perhaps weld all round and re-grind the taper. Quote Link to comment Share on other sites More sharing options...

If it does bend perhaps weld all round and re-grind the taper. Steve Almost certainly will to a certain extent, especially as it will take a fair bit of current to get some penetration. I'm sure it can be dealt with though. A weld 180 deg from the repair would probably help. I'll just have to wait and see what happens. At a real push a 349 shaft might be able to be used with an extension grafted on somehow. Looks like the extra part is the part of the 330 shaft that protrudes into the primary cavity and onto which the kickstart gear idles. The 349 shaft does not go through into that cavity. Wayne...

heavydabber Posted November 23, 2009 Report Share Posted November 23, 2009 Sunday the day of rest? Well had to break the 250 Gripper down a bit more. Front end today.1st slight challenge was there was the end of a 5mm allen key broken off in one the the yoke pinch bolts. Took the other screw out and just hacksawed through the screw in the slot. Head then just dropped out. Thought I'd have to drill the rest of the screw out so once the yoke was off I set it up in the milling machine but as soon as the drill touched the back of the screw it wound it out. Headstock bearing outers came out of the frame fairly easily. and used my usual method to remove the bottom inner from the stem by heating the bottom yoke a bit and just pressing the stem out. Forks will need re chroming and one is slightly bent. Also one seems to have a problem as the leg can be pulled way way out of the slider! I expect a circlip has popped at the bottom of the leg or even missing. They can wait a bit. Any recommendations for decent fork refinishers? I now have a reasonable batch to get done! Wayne.... Wayne, for fork rechroming try Dynasurf in Cheshire. Their main line of work is resurfacing piston rams on JCB's/Cats etc but they seem to do stanchions as a bit of a sideline, I had some Marzocchis done a couple of years back and it was about Quote Link to comment Share on other sites More sharing options...
