--- Quote ---I have a series 3 that has done 91,000 miles, the gearbox & synchro is fine, but finding first gear is very hard, is it likely to be a matter of renewing the detent balls selector forks and gear lever? if so how easy is it to do this? I am pretty able mechanically, but just not experienced in Landy gearboxes!

take the floor, the seatbox and the transmission tunnel out and you can get to the top of the box. you ca then remove the detent springs for the 3rd/4th and reverse selectors, two L shaped brackets, one on each side of the gearbox. next you can remove the top of the box the detent ball and spring for 1st/2nd are beneath the brass plug in the top cover so be carefull when removing the top of the gearbox.

you should now be able to see the selector rods and the 3rd/4th selector fork, they look something like this;

the reverse selector is missing in the photo, 1st/2nd is the one closest to the camera.

Check the positions of the forks on the rods with the measurements given in the manual.  You can remove the selectors, it's a little bit fiddly but not too difficult.  If this looks ok, it's likely it's something to do with the 1st/2nd syncroniser unit.  to change this is a gearbox out job.

Many thanks for that, in particular the photo was very helpful, when I get a spare few hours I will have a go..
Thanks Andy

Having looked at the Green Bible. I think I will buy another box, strip and rebuild that, then fit it complete, rather than ponse about trying to fix what I've got in situ. At least then I can take my time and get it right.

there's a load more photos here

Spyderman:
Great pictures, thanks. Much easier than the line drawings in the manual.

If you're planning on buying a box to strip and rebuild wait till the Sodbury Sortout, I picked up what looks like a good box down there for 35 quid, trouble is you never know what state they're in till you get it home and opened up.

As a guide I spent about £250 on parts rebuilding my box.  I probably didn't need to replace everything I did, but I only wanted to be doing it the once.  It's just coming up to 1000 miles since I fitted it and so far it's been great  :D
