Speedometer Disassembly??
Posted: Sun Nov 06, 2011 1:27 pm
I have recently purchased a 150mph speedometer to replace the 85mph version on my '82 CBX. I'm currently rolling the mileage back on the replacement using an electric drill to match the actual miles on the bike. I'm estimating it will take a couple of days to subtract off the extra 7500 miles.
While I'm waiting, I've noticed that the inside of the lense has a minor water mark that while is not obvious, does distract from the overall look of the speedo. To clean the inside of the lense obviously requires disassembling the speedo housing. A quick examination suggests that the front bezel needs to come off but it looks like it is crimped on over the lip on the plastic housing.
So my question is - is this doable by a normal mechanically savy mortal without serious risk of bending the bezel beyond repair? If so could someone provide a little advice/instruction of how to accomplish this safely?
Also, what is the trick from removing the trip meter knob? The knob appears to be threaded on the inside and mates to a male threaded shaft on the speedo, but turning the knob just rolls the trip meter digits. Maybe some needle nose pliers past the rubber grommet to hold the shaft while turning the knob?
Any adice would be greatly appreciated.
