Getting a bit off a 5-speed linkage

Post by funkypaul »

Hi All,
I'm in the process of cleaning up a 5-speed gear linkage for my T25 and have one bit which I want to get off but can't. Didn't know if anyone had any tips.
It's this bit on the end here...

It has a wierd little hole type thing at the bottom where you'd normally expect a bolt head to be or something...

..and inside the tube bit there is what appears to be a nut, but it feels too rounded to be a nut and I can't get any grip on it with my socket set

[IMG:461:614]http://i89.photobucket.com/albums/k208/ ... 3small.jpg[/img]

Is that indeed meant to be a nut in there? (in which case I may be screwed because it's gone awfully rounded :? ).

Any advice on getting this bit off the main linkage rod?
Thanks a lot,
Paul

funkypaul,

If I am looking at the right bit, Haynes shows a SPRING PIN in that position, also known as a ROLL PIN, take a look at the link for a drawing of one. You are talking about the gearbox end of the linkage I take it?

As Bob says, knock it out/through with a punch, dont forget to replace the rubber bellows that fits over it, I dont think the one shown on your picky is available buut I used one off an old master cyc for that.

Ok, sorry. next problem, which way do I hit this thing through?

Option A - through the tube:

Option B - from the top:

And is there any technique to this? I guess it may just be brute force, but not having much luck from either direction so far,
thanks.
Paul

soak the life out of it with duck oil or wd40 etc for as long over night in a bowl if you can then using as closer size drift to the roll pin and with it in a vice drift it out!

option a would let you grip it with something once it has come out a little way, roll pin has parallel sides so it could go either way .

can anyone tell me what happens without the bellows? I've done about 20k without one, no probs so far....
