Evening all,
Doesn't it always happen this way - getting the bike ready for Ace Cafe this Sunday (Black Shadow day) I knew I had had a problem on the dynamo side - not charging last time I ran the bike - anyway I took the end cover off to find the commutator has "eaten" itself with once copper segment disappeared completely and some serious chunks missing from the carbon brushes as a result.
I was advised to speak to Stuart Towner and sure enough he will be able to sort the dynamo for me - hurray, however the question for the Forum this evening is about running the bike this weekend.
I've got a 14AH battery - so fully charged there will be no problem riding the bike in daylight to and from the Ace - even though she's on electronic ignition it pulls next to nothing from the battery.
My question for the Forum is about leaving the bike safe and rideable for the trip. I don't want to leave the dynamo running as is, if something else breaks down and the dynamo seizes there could be bigger problems!! Removing the dynamo from the bike would leave the bike not oiltight - so seems sensible to leave it in place if I can and remove/disconnect the drive.
I've opened up the primary inspection cover, removed the assembly as follows on drawing M014 - nut (198), (dynamo lock washer PD23 is missing), dynamo drive plate (PD17AS), dynamo sprocket (PD15/1), dynamo oil thrower (PD28) and so only dynamo sprocket boss PD16 is left on the shaft.
Question - am I safe to button up again and run the bike with PD16 left on the shaft with no lock nut? Or should I use nut 198 to tighten up on the end of the shaft, although there doesn't appear to be any way of getting some purchase on the nut whilst holding and preventing the dynamo armature shaft from spinning.
Or should PD16 come off - if so, any bright ideas of how to pull it off?
If that's done, does that mean everything is off that needs to come off the primary drive side and I can simply replace the inspection cover and happily ride the bike?
Thanks all.
Stuart
