Title: Question for the experts
Post by: BazaJT on 30 October 2016, 08:03:41
A mate of mine read something off the internet regarding a Vx 6 speed gearbox-I think it was a MT something or other can't remember the numbers which followed-this company claimed to be able to rebuild said box using new bearings,seals,gaskets etc for less cost than usual as they'd worked out a way to do it without taking the box off the vehicle.Now it is many many years since I last stripped and rebuilt a gearbox[it was from a V4 Transit!] but I just don't see how you can  strip/rebuild a gearbox while it's still in situ.So any experts on here who can enlighten me? Can it be done in this way?

I don't really understand the cost saving - getting a gearbox off isn't fairly easy but working on one in place must be impossible / total nightmare.....

I am bemused, too!
The only gearbox Ihave ever had apart was a Burman box from my old Panther motorbike and even that was complex enough for this amateur, but I simply cannot see that it could be cost-effective, even if this bloke were clever enough, to do it in situ.
As we all know, the major part of workshop costs is labour time, and it surely must take longer and be more awkward to try to jiggle things about from underneath the car whilst it is on the ramp than to dismantle it with the gearbox on the workbench?
I also await more expert opinion.....

Hypothetically, you remove the rear cover and pull everything out that way...

Can't see it working too well on front wheel drive cars, but a bit more viable on rear wheel drive... not sure that I  would fancy rebuilding it in situ though ::)

Strewth, Bigron...... You must date back to the dawn of time. ;)

Doctor Opti, considering how many parts of me seem to be reminding me of that fact, I think you are right! However, in my defence, I bought one of the last models that were made when Phelon & Moore went into liquidation and sold their remaining stock through George Clarke in Brixton, south London - memories, anyone?
That bike nearly broke my ankle when, one sleepy morning, I forgot to engage the half-compression lever (650cc single cylinder, if you didn't know) and kick-started it: it kicked back, and I limped back upstairs to bed, no work for me that day!

Silky smooth and vibe free then. ;)

I get nothing but rudeness on here, ever since I owned up to once owning a Wartburg!
Still, you do get a better class of insult here..... 8)

Its the M32 FWD box, quite involved to remove  (subframe off etc) and can be very effectively re-built in situ (but you have to lower the subframe a slightly).

Once the cover is off you can remove the 3 shafts easily enough to the bench for work and the hardest part is the bearing shells in the bit left on the car.

Similarly the diff is easily removed

I suppose its the same principle as the old Hewland gearboxes found on most racing cars years ago. A place could be unbolted from the rear of the unit and the internals changed around in a short space of time.
Drivers would have a sudden change of mind about a particular ratio as they were about to line up on the grid and a mechanic could change it in no time.

Presumably once the end cover and internals are removed, the casing drops out through the subframe easily enough:-\

The M32 yes that's the letters/numbers I wasn't sure of.A mate of mine is going to be on with doing his[on an Insignia]this weekend.

Main casing stays put, the rotating bits are removed.  :y
