Crankshaft Nut When fitting Alton Electric start

john_price · Apr 5, 2024

Hi I have fitted the Electric start kit all going well until it comes to putting on the Crankshaft nut, mu original can be put on by hand and threads on and off very smooth , howeve the nut supplied by Alton grips then stops , I do not want to force it and damage the threads on the crank, has anyone else had this issue the bike is a 750 Mk5 1973 , I have emailed Alton and I am waiting for a reply

Mine was a very tight fit. Couldn't turn it by hand but it did go on and has been ok.

Have you had a response from Alton??

Just a thought but try oiling it and putting it on backwards to test the threads. It my just be stiff which is not a bad thing.
If successful, clean all traces of oil and try the correct way on...
