Periodically I see how to disassembly guides for gauges with chrome/stainless rings holding the two halves of the outer cases together - you know, the ones where you use a watchmakers screwdriver, paint can opener or other suitable picky-tool to prise one side of the ring up? Generally, they're the types of clocks you find on later CB/CL350s and the K2 SL350. Those guides are great, and I've just done something similar with a CA77 speedo so I could clean up the face.
Unfortunately, I've got a set of gauges that I need to overhaul that are different. They're from an XL350 K0, but the same outer case design was used on the SL350 K0 models (I suspect they shared the same clocks with earlier CB/CL's as well). The lens on the front of the speedo is cracked, and both the speedo and tacho faces have faded. I'd like to get them apart, tart them up, clean the number dials and sort out the lens issue by swapping in another lens. But as far as I can make out, they're sealed with no separator rings. I'm not entirely sure how they were sealed; they look as though the backs of the cases have been fused with the fronts. No photos right now; I'll try and add one or two later.
I don't recall seeing any guides for these types of clocks - and maybe for good reason - but I'm wondering whether anyone's pulled any of the sealed type apart and if so, is there a non-destructive way of getting into them? I have a nasty feeling I'm going to have to end up butchering the plastic around the area that will ultimately be hidden by the rubber cushion in the chrome housing and somehow gluing the bits back together when I'm done . . . but if there's a better way (or at least one where I'm less likely to crack or break something) it would be good to know about it before I charge in with some sort of cutting tool.
Any/all ideas gratefully received. And thanks in advance.
