Folks,

I am looking for instruction sheet on how to take a 7A apart. I acquired a used one with one of the needles kind of bent and both dials washed out. The internal mechanism appears to work just fine.

From Southwest Industries I bought the needles, the dials, and the maintenance kit. Now I need to find out how these units come apart. I got some pictures from another gentleman, but they are for the model 6 with dial knob.

Thank you, I appreciate any help. On the other hand if anyone who has done this work and willing to do mine for a fee, I will be all over it.

Nez, they are not overly complicated. I've cleaned quite a few of them and you need to go slow, try to keep track what goes where, with photos would make life easier,

What I found was the plastic gear teeth looked destroyed by metal chips that migrate into the unit. I found a large needle or a very small scratch awl would scrape the metal chips out of the gears and usually they were still serviceable. Disassemble the unit, thoroughly clean the parts, grease and reassemble and you are back in business. Just be sure you install a new wiper and scraper. The scrapers last a long time, the wipers should be changed often.

Its just a gear box and it's pretty hard for someone with your slkills to screw one up.

If you find you trashed it and are pitching it.....pitch it my way. :cool:

Terry,

Thank you I will give it a go. I still would like to see the disassembly manual. How do the dial pointers come out? How about the dials, how do they come out?

North Texas Precision in the DFW area. I will make an attempt to take it apart, recondition it myself.

I recently acquired a SBL 13, I need to get the TravADial going, it just looks a perfect fit in the lathe instead of a DRO.
