Drive sprocket locking plate
Posted: Mon Mar 18, 2024 10:16 am
Hello all,
I thought I would post this in case it might be useful to anyone else who has run into this problem.
As part of my build I decided to fit a 530 chain set to my Z900 A4 but I couldn't find any satisfactory method of locking the nut in position.
The 530 sprocket has two m6 tapped holes on 42mm centres and I spent ages looking for something of the shelf I could adapt without much luck.
In the end I decided to make my own. I found a suitable starting washer on metalpartsdirect.co.uk -
Stainless Steel 316 Washer 54mm X 20mm X 0.9mm Thick M18
I then marked on the washer with my design and used an angle grinder with a 1.0mm metal cutting disc and then a Dremel to finish.
When installing I used two short M6 grub screws to hold the plate and stop it rotating when torquing up the main nut.
I had to use grub screws instead of bolts to allow clearance for the 27mm socket. I then swapped the grub screws for two dome head hex screws.
