I posted this question in the "Lubing Spline" thread that I started but I think the question may have been lost in all the other interesting stuff that is going on in that thread now. So here's what I posted...any feedback would be appreciated:
One of the reasons I was taking the drive line apart on my R65 was to replace the coil spring and inspect the couplers. I wanted to do this as last summer the bike was sort of pulsating in the drive line when under heavy throttle when accelerating.
I now have the swing arm off and am looking at how to get at the spring to replace it. But I am confused (nothing new here). When I look at my Clymer manual on page 546, figure 45 illustrates a nut holding a rear coupling in place on the drive shaft....no spring in this illustration. However from the RealOEM parts diagram of the drive shaft a spring is shown in the assembly. Is the spring part of the drive-shaft assembly contained in the swing arm assembly or is it external to the drive-shaft and contained in the transmission output?
Also the nut that is shown in the Clymer manual at the end of the drive-shaft does not exist on mine. There seems to be a ring of some kind with a half moon cut-out in the outer edge. I don't believe it is a snap ring.... If it is I've never seen one like it. Assuming that the spring is contained within the drive shaft assembly can anyone tell me how to get this apart...remember this is a 79, twin shock R65. Later models are probably different.
The Clymer manual also indicates that I will need a hydraulic press to get the drive-shaft apart. Is this true and is there some kind of thing I could rig up in place of a hydraulic press? This could be a show stopper for me. Anyone???
