C15 speedometer
« on: 15 February, 2017, 06:06:49 »
Hello people
                  Some of you may remember I am restoring a C 15.
                   Starting to put some bits back on the bike. But speedo is locked solid.
                   Any ideas just seen something similar for 300 !!!!!
                    Feeling a bit poorly.
Is none working a MOT failure ?
Regards as usual
                         Tim

Tim. It might be possible to save the speedo but you would need to lever off and replace the old bezel to get at the internals. It's likely a bearing has seized and will need to be freed off and re-lubricated - I've had a similar problem before. In principle, it's an MOT failure but it's something they don't test for!

Thanks for that Arthur.
You may remember Giving me some advice on the rear guard fixing.
I managed to get one side out to expose the thread inside it looks like 5/16 dia. But what thread type?
The other not enough metal left to extract it.
I will have to drill and retap.
Regards

Hi Tim.

You'll find most of the threads are BSC - the required bolts are 1/4 x 1/2 BSC. The tapped lugs are a bugger to drill out because of the limited space available between the sub-frame down tubes.
