These spare parts are for all recent model Bestest vertical style indicators ending in -3. We do not have parts for the older models ending in -1 or -2. Tesatast vertical indicators use the same parts with the exception of the dial.

Repairs: Special tools are required for certain steps in the repair process. If you'd rather have us take a look at your indicators please see page 30.

Notes

 

Complete repair instructions are available. Click here for details.

The old crystals are removed with a special tool which acts like a suction cup. You can improvise other methods but you're likely to cause damage. Often times the new crystal, which is slightly convex, can be snapped in by hand, but even here, we use special equipment to avoid damage to the indicator. It's best to leave this to someone with the right tools.

Crystals sold on this page are intended only for those Bestest models ending in -3 or -5. Crystals for obsolete models can be found on page 233.

Unlike many other test indicators, the bezel can not be removed without complete disassembly.

(*) Movement disc (023042) is not suitable for parallel model 7021.

The orange hands are ridiculously expensive to buy so here is a word of warning: just about any cleaning product will wash away the orange paint, so don't try to clean them. You can successfully paint them using fluorescent orange enamel paint available at hobby and craft stores. (Acrylic paints do not offer sufficient coverage for a bright finish.)
