For Mitutoyo Series 513-400 manufactured between 1997 and 2016
Can it be fixed? (an excerpt from the Repair Manual)
We shall begin by examining the Mitutoyo indicator to see if it is worth repairing. The most common reasons why these indicators come in for repair:
Mitutoyo has changed the design and construction of its indicators many times since the 1960s. You are not likely to find spare parts for models made prior to 1997.
➡ Before you invest any time in a repair attempt, make sure you won’t need any obsolete parts.
Recent models rarely need more than a cleaning and a new bezel/crystal assembly. Even one additional part won’t break the bank.
For a successful repair, start at the beginning and follow all the steps in this book. Do not jump to any single conclusion. You will probably be disappointed with the results.
If you find that some aspect of the repair is not covered or is less than clear in this manual, please check this website for updates, customer questions and, hopefully, appropriate and useful answers.
