Flywheel puller?
« on: June 04, 2018, 08:15:55 PM »
What size bolt is needed to pull the fly wheel?  I thought I had a bad starter or the starter chain was skipping but it turns out that the starter gear is skipping.  I assume it is worn or the dowels are worn but want to pull the flywheel before I buy parts.

From here that looks more like slipping starter clutch which is very common on that era bike. Try rebuilding it with new springs and dowels.

That is what I meant.  Do you happen to know what size bolt for removing the flywheel?  I see a flywheel puller bolt on ebay right now but it is overseas and they want over $30 for it.

When the left side covers come off, is there oil in there? Do I need to drain it before I go after the starter mechanism, Mine is making the same slipping noise that yours is in the first video.

Hi there Callaghan yes you will need to drain the oil before removing the left engine cover which houses the starter clutch. Do you have a manual for this bike ? As this would provide some of the answers you will need . Also the articles on this site as nk140 , myself and others have done this repair.

Definitely drain the oil.  Don't be like me and pull the cover and dump oil all over the garage floor.  The repair is very easy once the flywheel is off.  I had to buy the repair kit from the UK.

  I didn't see anyone chime in on the puller bolt size ; it is 16mm x 1.5 thread pitch . I use an idler arm pivot bolt from a late 70's Mercedes , but you can probably find an appropriate bolt from a fastener supply company . Good luck with your project .
