This thread and series of posts covers the return-to-acceptable or return-to-functional service work done on an XS1B tachometer that had a severely sunbleached dial face, was exhibiting jittery/jumping needle and had poor internal illumination.
The terms 'overhaul', 'restoration', 'renew', 'refurbish', 'remanufactured', 'rebuild', generally mean a higher level of repair work, and are not really achievable here. An old instrument can have external damage and blemishes, internal cosmetic fading and blemishes, and internal mechanical wear/damage and problems. We can try to resurface blemished outer shells, polish up bezels, touch-up dial faces and needles, but at this time the only option is to acquire used instruments, clean and fix movement damage, including needle shaft bearings, and try to build a better instrument from the parts.
Here is a used tachometer that has a less-than-stellar enclosure, missing turn signal indicator lens, internal mechanical problems, but a useable dial face and pointer.
Update: Thread edited 11/22/2016, fixing pic display and ordering in the posts.
