Re: B44 clutch dragging

An update. The new friction plates arrived and they are .130 thick. Wonder why the manual states .167. New springs were longer than the (probably original) ones in there. New cups, new cable and all is now good; well, it is not dragging, I have not taken it out of second yet, so I might have slippin...

Re: B44 layshaft bearing removal

a couple of marks in the case, but they should sand out Don't, just let the Loctite fill the void, but if it is only small, the bearing will be supported without the need for loctite....

Re: B44 layshaft bearing removal

Yes an orange one!! The conical shaped one is probably best for getting into the far end of the needle bearing. As said, you are trying to grind a uniform small groove along the length of the bearing case until you weaken it enough to fracture. You need to be careful and accurate. You Sir are a sta...

I am surprised a stone will cut through it, but I will give it a go. The orange one I am guessing? And it is the "carefully" bit that I have to watch

Re: B44 layshaft bearing removal

I've removed quite a few of these and have done it using a Dremel and grinding bit in order to grind away a groove on one side of the bearing case after removing the needles. It's fiddly work but, once you've ground almost all the way through the metal from one end of the bearing to the other, you ...

B44 layshaft bearing removal

I am having the devil of a job removing the layshaft bearing from a B44 engine. Started work on a spare engine and found that there were no needles at all in the bearing, just the outer sleeve. I tried the coach bolt trick (found on this forum) to use it as a puller and thought it was working until ...

Re: B44 clutch dragging

3mm clutch plates sound normal to me. 4.242mm (.167") is way thicker than any I have ever seen. Just a shot in the dark, but is the clutch handle correct? Some handles have the fulcrum pin closer to the handlebar which decreases the amount of pull. Also, some of the new cables they sell are so spon...
