unknown washer in distributor

[DaveDUk]

Hi all,
I Stripped my distributor down because I was having a lot of starting problems. The thing was in a right mess. Ball bearing stuck, points heavily pitted, very messy overall. I was not really noting things when i took it apart because I have a 123 electronic on order. However it is taking longer to arrive than I thought (brexit) so I have cleaned the old one, put new points into it etc and I'm getting ready to try it back in the car which is a SL230 1966 with a 051 distributor.
Problem: I have a 25mm dia plastic washer that I cant work out where it goes. If I put it where I thought, which was under the contact breaker plate I cant get the plate to screw into the distributor body.
Can someone tell me where is goes. Many Thanks.

It goes under the breaker plate. There are a number of thinner metal shims under the fiber shim that you may need to adjust to get the right free play on the cam lobe shaft.

thanks Dan
I thought that was the case but I cant seem to get the breaker plate to fit then to the body, there are two thinner metal shim type washers...I will give it another try with a bit of pushing I might be able to reconnect the plate to the body.

Remove any metal shims if the assembly won't turn freely. Metal shims first then the fibre washer on top. You should have lots of free play even with everything installed that you removed.

And to save you the bother, I have 123 distributors in stock.....
