Sun SST-802 Tachometer Restoration: Sender-Free Upgrade

Sun SST-802 Tachometer Restoration

This Sun SST-802 came to our shop with a failed circuit board, a weathered case, and signs of heavy use — a typical example of the wear we often see on these iconic tachometers. Like many SST-802 units we restore, it was brought back to life with a full cosmetic and functional overhaul, including a modern sender-free upgrade.


About the SST-802

A staple of 1960s and 1970s muscle cars, the Sun SST-802 is one of the most requested tachometers we see at Calibrated Classics. We’ve restored dozens of these units for customers around the country — each with its own unique condition, quirks, and needs.

This post highlights one of many SST-802 restorations in our portfolio.


Restoration Highlights

For this particular gauge, we performed the following work:

  • Complete teardown and ultrasonic cleaning
  • Meter movement cleaned, serviced, and pointer rebalanced
  • Dial carefully restored to maintain original character
  • Chrome bezel replaced with a replated original
  • Housing and lighting system cleaned and restored
  • Westach internal circuit board installed to eliminate the external sender box
  • Leads labeled for simple signal + ground hookup

This upgrade gives the tach modern reliability while maintaining its original appearance.
