Jumping out of 2nd gear, is it time for a new box?
Discussion
I've got a 3000m which has now started to jump out of 2nd gear, usually when I lift of the gas.
is this a relatively simple job to fix or does the box need replacing?
I'm assuming I can drop the box while leaving the engine in, can I leave the bellhousing on the engine.... I think a bit of advice would go down well about now!?
Thanks in advance

You can sometimes just put a 2mm spacer under the detent spring and keep it in gear. Very often the detent "V" becomes a little rounded so the ball does not hold into the detent as strongly as when the gearbox was new.
Worth a try as no removal of the gearbox necessary.www.pistonheads.com/gassing/icons/4.gif

If you do decide to drop the box its not a trivial job, as most/all the exhaust needs to come off. Also the bell housing is not easy to get out under the car if its still attached to the box (as the whole assembly is quite tall and you need the car high up to do it effectively)
I'd recommend Pitero's advice, talk to Steve Reid or Adrian Venn

Cheers guys,
Had a good chat with Adrian Venn last night, talked me through the process for dropping the box and recommended getting a friend or two to help lift it out due to the weight.
He thinks its likely to be the syncro and already has a few rebuilt boxes on the shelf, I'm tempted to see if I can get the parts to fix the box from Adrian and rebuild it myself.
Anyone rebuilt a box before? or is it not worth the hassle?

Just remember its a bastard to get out and even more of a bastard to put back (I'm not kidding here). I reckon putting the box back after a clutch change was one of the hardest (physical) jobs I ever did on my Taimar. I'd be very tempted to drive it to Adrian, leave him some cash, go out for the day (Transport Museum in Coventry perhaps), pick the car up with an exchange box and drive it home.
You know it makes sense!

PS if you do tackle the job remember you have been warned!

Come on Davidy. Stop being a mard a**e
Now wheres the fun in paying someone else to do it.
its not so bad if you support the rear end of the box on a trolley jack.
Makes me remember the time when I left my dad trapped under an MT75 4X4 box struggling while i went for a cuppa. laugh! I thought me pants would never dry.
In all seriousness I don't mind changing clutches and Boxes but i always stop short of re-building them. Chances are you will need a whole load of circlip pliers and the odd special tool which will make the job very difficult.
Check adrians price for supply only and supply and fit and go from there.

The main issue with an M series box with the bell housing on is the weight and the very limited access. Just work out how high you have to get the car up to get the assembly in and out underneath! Fine if you have a pit or large ramps, but with my car on the top of four tall axle stands and using a trolley jack to support the box I found it not easy, but then I wasn't a serial clutch replacer!
I'm just flagging a warning that without the right access the job is not trivial.

Secret is to have a well rounded belly like mine.
You can then slide the box onto your belly and pull it over your face ripping your glasses off in the process. The trick is then to breath in and swell the old beer gut to lift the back end of the box and align the pinion shaft.
Then use your seven foot arm to turn the rear pinion shaft to line up the splines and hey presto.
.
What else would you do on a sunday?
!
your right though I don't think I have ever messed with a heavier engine and box, except perhaps in a commercial vehicle.
You sound like you have reached that sensible age Davidy.
I have just finished swapping the best of 2 vixens about and my engine and clutch now assemble themselves when I whistle

A Vixen is a mere lightweight 
capable of being picked up by one hand (well almost) - Great cars though and much more nimble than any M-series (I reckon my wife's S1 would corner about as fast as my Impreza Turbo on tight roundabouts - though it would never look as if it was pointing in the right direction though!!!)
Alex hope you get it sorted
