brucy Posted September 15, 2007 Share Posted September 15, 2007 on the way home tonight i've noticed that the gearbox has started to crunch when going into 3rd (up and down).Is it new box time? all other gear changes seem fine and the reservoir is full so i'm inclined to think that i need a new one :-/Any ideas?Andy Link to comment Share on other sites More sharing options...
heraldcoupe Posted September 15, 2007 Share Posted September 15, 2007 Synchromesh on third is wearing out, the rest of the box may be fine. Learn to double declutch and save yourself a few quid! The gearbox can go on for years like this.Cheers,Bill. Link to comment Share on other sites More sharing options...
brucy Posted September 15, 2007 Author Share Posted September 15, 2007 I already have to double declutch because the same (i presume) has already happened on 2nd :(The only gear with a syncro is 4th :-/ Link to comment Share on other sites More sharing options...

toomanyprojects Posted September 15, 2007 Share Posted September 15, 2007 My spits done 40,000+ miles with 2nd and 3rd screaming when you lift off and no synch on any gear. I'm going to change it when it breaks..... Link to comment Share on other sites More sharing options...
Tim Bancroft Posted September 16, 2007 Share Posted September 16, 2007 Might be cheaper to fix now rather than waiting for it to get really bad. Link to comment Share on other sites More sharing options...

How easy is it to rebuild a box or am i looking at exchange/upgrade?Andy Link to comment Share on other sites More sharing options...
CharlieB Posted September 16, 2007 Share Posted September 16, 2007 Rebuilding a gearbox isn't too bad a job but I had to do mine twice as I made the mistake of fitting new synchro rings, DON'T they're useless. Fit either NOS or good ones from another box, the 4th gear one gets the least wear. Also replace the 3 springs in the synchro hubs, some of mine were broken.It would have been less hassle to get an exchange!ps mine was a single rail but I think the same things apply?

rotoflex Posted September 17, 2007 Share Posted September 17, 2007 Losing so many synchros is thought-provoking. They're gone now, but the important thing to remember is that GL4-spec gear oil should be used in the transmission, not the more commonly-available GL5. Anybody who's unsure of what's in there should drain the tranny & put in the right stuff. GL5 is not friendly to chewy yellow-metal synchros.I have also heard that the replacement synchros these days don't last as well as the original items. If someone does rebuild a box with modern replacement synchros, it would be a worthwhile (couldn't be worse, might be good) experiment to use a synthetic instead of mineral-based gear oil.

Deleted User Posted September 26, 2007 Share Posted September 26, 2007 theres loadsa GB's inc a 13/60 OD box AND engine ;) do the 1300's fit? Link to comment Share on other sites More sharing options...
Clive Posted September 26, 2007 Share Posted September 26, 2007 all herald and spit 1-IV will fit. Ideal is a spit IV as it is 4 synchro. Avoid the very early herald box that is all ally and not seperate bellhousing. Link to comment Share on other sites More sharing options...
