3/4” collet wrench

Have you tried www.ereplacementparts.com ? They should have an original replacement wrench for your router. They carry parts for most major brands of tools, and I've been very satisfied in my dealings with them. Exploded views and parts lists are on their website, so it's easy to pick out what you need, and they will have it delivered to you in just a few days, in most cases.

or a tappet wrench...

Thanks Charlie, nice site, bought the wrench.
Isn’t 3/4” a bit big for a tappet wrench?

I can’t find how to mark this post as ‘found’.
