Speedometer-Tachometer Squeal
Getter ever closer to being able to fire up my 1983 RZ.
So now is a good time to check the speedo.
Hooked my drill motor to the cables to check function.
Everything works as desired however both the speedo and tach are giving a high pitch SQUEAL.
Any ideas on cause?

Re: Speedometer-Tachometer Squeal
My speedo started to howl so bad I could hear it with earplugs in under my helmet. I pulled the cable and stuck the straw on a can of cable lube up the hole and gave it a good squirt, problem solved. This also fixed the reed switch in there and made my self cancelling signals start working again. I would not do this with the speedo off the bike as lube might head down to the face and stain it. My '85 tach is electronic but I would imagine the same would work on a mechanical tach.

Happens often, don't use mine as much so it has been a while I had this. If I remember correctly I used silicone spray on mine. Did a quick search and found these posts that may be of some help:b-bike393 wrote:Getter ever closer to being able to fire up my 1983 RZ.

Re: Speedometer-Tachometer Squeal
Don't forget that little gear thing in the front wheel. If the speedo has dried up, that might also be close to seizing! We bought an RZ in a forest environment and actually had to replace that whole thing w/ a spare it was rusted so bad. I'm thinking that if you could get the lube in there Slyglide might be a good option. I know my machinist recommends that for points cams and it is a bit thicker. Better to take that area apart, clean and relube before it is too late and replacements parts near unobtainable!!

Re: Speedometer-Tachometer Squeal
Once again, you guys rock. I'm always amazed by the wealth of knowledge that is on this web-site.
Beings I have not mounted my gauges, I'm going to disassemble the whole unit, remove each meter, heavy grease the gears, silicone/graphite lube the input bushing area and lube the brand new cables.
I'll post up the results.
Thanks guys.

Re: Speedometer-Tachometer Squeal
That should do it. I greased the speedo drive and used PB Blaster dri lube on mine and at least for the present mine is behaving itself...
I love the smell of Blue Marble in the morning!

As RuZty stated above, the faces on these instruments are extremely sensitive. I know.
Don't let anything get on them or they will be ruined.

Re: Speedometer-Tachometer Squeal
My recommendation? if you have the squeal, STOP. NOW. Remove the cluster, remove the covers, you can then see how to properly lubricate the offending drive mechanism.
