And I bet the quote to replace the idler and sprockets at the same time, so as to avoid wearing the new chain out rapidly, will be rejected.For example that chain is likely knackered. But it won't be replaced until it breaks

Saw some pictures of 3/4" pitch pin chain sprockets this week used to prior to an oven in a plant - the gullet of the teeth so worn, they must have been double the original depth - yet new chain fitted recently . . .
