These parts are for all recent model Bestest horizontal indicators ending in -3 or -5. The only difference between the two is the color of the dials, spacing ring and the hand.

We do not have parts for the older models ending in -1 or -2. Tesatast indicators use the same parts with the exception of the dial.

Spare parts for vertical models are shown on page 225.

Repairs: if you'd rather have us take a look at your indicators please see page 30.

To order Bestest and Tesatast spare parts, click on any part number where the price is shown (in US$). B&S and TESA parts are identical but have different ordering numbers. TESA part numbers are used when you order from us.

September 2016: New BesTest dials are made of plastic and no longer have the model number printed on them. Instead, all new indicators have the number etched on the body cover plate. If you need to replace the old dial, be sure to scratch the model number on the body somewhere, so that you will know which model you have. Otherwise, it could be difficult for you to order correct parts in the future.

Time has told us that there is a manufacturer "glitch" which has inadvertently marked some parts are obsolete. "Glitch" is another way of saying that somebody screwed up. Apparently the dial part numbers are being changed. We will post the new information as it becomes available.

Do you need repair tools? Check to see what the professionals use on page 31.

Important: Spare parts can only be ordered online. Simply click on the linked part numbers below. We cannot accept purchase orders for spare parts.

* new dials are plastic and do not have model numbers printed on them. If you are replacing the dial on an older indicator, be sure to mark the model number on the body, just below the engraved serial number. This will make it easier to reorder spare parts in the future.

How to place an order: Click on any part number which has a price shown.

Notes

 

The damaged 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 are no longer available from us.

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

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


Orange Fluorescent Enamel Paint Testors 1/4 Oz

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. Painting the hand with fluorescent red or orange enamel will work, but acrylic paints are not very good for this job.

The "complete movement" is inside the body, held in place by two flat head screws. If the crown gear is damaged, jewel is cracked, or the whole movement is hopelessly cruddy, this may be a quick, although costly, fix. Also, if the accuracy is off by just a bit and you are convinced that you have the correct contact point and the correct pivot installed, then replacing the movement may solve the problem.

 

IMG_1257IMG_1261

Do not forget the anti-shock spring (023413). It prevents over-travel and should always be installed. Nothing holds it in place. It will fall out on its own if you open the cover or start to clean the movement. The spring simply drops into the opening as shown in these photos.
