    I'm in the process of taking my case apart and cleaning and putting back together. I just got the rear tailshaft housing off. There's a blue thing on the shaft that is grooved that looks like where the speedo gear rides. There are several grooves that are destroyed/worn down that don't look right. Replace? What the heck is it? And can it cause a vibration to come and go? Thanks in advance.

    Furthermore, there's a black plastic thing with three tabs behind this blue thing that appears won't come off unless the blue thing comes off. Does all of this need to come off before I take off the back off of the case?

    I was looking at that when I had to replace my tail shaft housing. It does looks like the speedo gear. Does your Speedometer jump/skip? If it skips I'd replace it...

    Sorry don't know much about them but figured I'd throw that question out.

    It jumps a little bit but not enough to be irritating. I'm not going to mess around with it since that's not my primary focus. I'm trying to find a vibration and so far I haven't found it. Now I need to run to the store for fluid and stuff and take a look at the radiator.

    Thanks. I've already put the housing back on since I can't hardly find anything that I need due to a recent move. Hoprefully just resealing the housing will fix the problem.

    I've got it back together and took it down to the car wash to get some of the grime off. I'm wondering, do I need a special tool to take any of that stuff off of the shaft. That green grooved thing is on there pretty tight.

    The only time you need any special tools is if you are replacing the bearings, a slide hammer and bearing press would come in handy then.
