NORM.Thanks for your comments but this problem occurs immediately I set off with a stone cold gearbox and without leaning the bike.The bearing seems to be firmly held in its' housing.

MARK I'll inspect the pin when I finally get it out and see what condition it's in.

Dave, these things are very primitive in there and I can't say I have ever taken any notice as to how much sideplay the selector has, but if you say it is going off at an angle then something is not square, something must be bent, should be easy to see as you move the selector. If it was me and the sideplay was the issue, I would make up a half washer and slip it between the case and the shifter and then put a spot of weld on it to hold the washer in place. What have you got to loose, the box is stripped down so easy to clean out after welding and at the end of the day it is only an Albion

Dave, welding that is probably not my best idea, just push selector the way you want it to go and put a cable tie in there, you are only trying to prove this is the problem but I doubt that it is. If it solves the problem you can then think about pulling the motor out. Otherwise just replace first gear and the sliding gear, something must be worn in there

[Norm]

Dave, probably not my best idea, just push the selector to the side you want it to be and put a cable tie around the shaft to hold it in place. You only want to prove that it is a problem with the selector. If it solves the problem then you can pull the box and fix the problem. I doubt this is the problem but if you are sure the bearing and mainshaft sleve are not moving then replace the first gear and the sliding gear but I would expect to see some damage on the dogs

Well, I've finally got it all apart. I'm surprised it didn't jump out of all gears.The selector looks as if it was made by a myopic spotty herbert in a third form metalwork class. The profile of the detents and that of the detent plunger bare little relation to one another and only about half the width of the selector has been engaging with the plunger! I'm not yet sure how to proceed,I think the girls at the local sixth form college could make me a better component. The bike has been great over the last twenty odd thousand miles but I'm appalled, appalled I tell you, at this recent discovery. There isn't much material around the first gear detent so if I have at it with a file there's a danger that the thing will break. I think I'll have a ride over to our hosts tomorrow to see if they have a better component in stock as I'm sure they probably vary. A good excuse to have a ride on the Guzzi !!
