Hi guys, the resto is still progressing but have come across a few speedbumps. The first (and probably the biggest concern) is the drive side case has a chip out of it right where the crankshaft bearing is pressed into. It is about 1-1.5 cm long so maybe it is about 1/10 of the total circumference. it is on the top inside edge. Also the remaining case lip surrounding the bearing has been peened about 30 times to prevent the bearing outer race from spinning (i presume). My first question is can this be repaired to a suitable strength for this critical location. I thought being on the top it might be OK?, I have searched hi and lo and haven't really found a definitive answer on this. Has anyone had a similiar repair done and how successfull was it, and if so is there anyone in Australia that can be recomended. The main reason I'm looking to repair instead of replace is that the cases and frame are a 52 Star twin (with HC stamped as well just below the eng #) and I would prefer to keep them as an item (also avoiding the eng # complications for registration/ insurance, etc). There has also been a repair done on what was obviously a crack on the rear flange that sticks out aft (where the trans shaft goes through). It is about half way between the eng case and the hole for the trans shaft. It looks like it has been done quite a while ago and appears to be holding OK. Do these two together make it not worthwhile??
The next question is related to the rear hub, 52 plunger quick disconnect type. I have removed the spokes/ rim and have cleaned the hub up in preparation for repaint and have noticed some movement between the L & R halves of the hub. It looks like there is an inner sleeve that has been riveted to the two halves to make a whole and that there is some wear on the rivets. This allows aprox some small movement (maybe .25mm but enough to be easily seen by eye and feel). is this acceptable, does the movement get stopped when all the spokes are in and tightened. I certainly didn't notice any when the wheel was together (but I wasn't looking for it either), it was only apparent after the cleaning. Or can the rivets be drilled out and replaced somehow. So hopefully amongst the pooled wisdom out there somebody has come across either of these challenges.........and has a solution/ answer ........Cheers Todd
