Title: Speedo
Post by: The Doctor on November 15, 2018, 03:43:37 am
Have the front wheel off in order to put new rubbers on her. Looking down where the speedometer housing attached I saw the following picture. Is that about what it should be? Should I clean it out? Reapply grease? The mix of black and brass color concerns me. Is the black just grime, or is it a seal? Just don't wanna start digging around and accidentally mess something up, but figured since I already have the wheel off, I should get to it now rather than later. Looked in the shop manual and it didn't really say much.

Looks like dirt mate. Also, it looks like the outer bearing has taken a beating what I can see on the bottom where the axle goes.

No harm in cleaning it up. Not sure if the previous owner was a fan of over lubricating with grease.
The important thing is when you put it back in the wheel that there are tabs on the speedo housing that have to line up to the wheel. Others have not assured that these are lined up and when installing the wheel have bent the tabs that wherent lined up.

FYI, Most replace the wheel bearings every other tire change but others have never changed them.

definately clean and regrease everytime you pull the wheel, i also pop the outside seal off the bearing with a boxcutter blade and fill with fresh grease.i bought bearings that when brand new and when i look inside there's only the equivalent of about 3 grains of rice in grease,some times their full but its worth checking.
