Odometer repair no longer working :-(

[mrdjsk]

I was thrilled to follow the dieselgiant's DIY routine for speedometer repair on my 1983 300D (W123). The procedure worked for about 1K, but has now stopped.

I didn't use Loctite on the repair, so I guess I'll open it back up and try again.

Any advice from people who had to do this repair twice?

Thanks.
