Hi, just picked up very sad Croma 2.2 petrol. clutch slave cylinder is u/s. Rear shocks have had it and camshaft codes on obd. What do you expect for £200? Runs great so engine seems good so far. Any tips on dropping the gearbox? I've done a couple of clutches before but never with a subframe and with the help of a Haynes manual, I assume there isn't one for a croma :)
 
You'd be correct, i think. It's a 2005. I'll check out the manuals suggested.Still interested if anyone has any tips on dropping the gearbox? I've ordered a new slave cylinder and I'm going to give it a go on the weekend, what could go possibly go wrong?
 
It'll be a Vauxhall (GM) kit so the Vectra or better still Signum manual is the one to look for.

My advice is don't hesitate to dismantle anything you need to in order to make space for yourself.

The box will just be bastard heavy.. about 40kg... and you will have to take the driveshaft out to get the beast out probably... then balance it on a gearbox hoist or a trolley jack until you pull it off the engine and can lower it to the ground.

Also, put the car on stands but leave room/the nearside jacking point free so you can jack it up further once you've got the gearbox onto the ground, in order to be able to get it out from under the car.

Before you remove the box from the engine, put some layers of cardboard under the car so that if/when you drop the box off the jack onto the ground, it has a soft landing *and* if the cardboard is big enough, you'll be able to haul the box around into the garage etc.

I found that a TV box is ideal .. so tell your missus you need that new 55" so that you can fix your car.. :D

Hi,
The offical electronic service info "eLearn" can be downloaded on the forum here

I've not dropped the box so do't know of any tips.

However it might be worth changing the mainshaft endcase bearings (assuming it's the 6 speed "M32" gearbox). They are a weak point. Not too expensive https://www.ebay.co.uk/itm/M32-Gearbox-Top-3-Mainshaft-End-Case-Bearing-Repair-Set-Fits-Astra-6sp/123151985107?
You don't want to take it out twice.

Many thanks, I'll give a go, never had much luck downloading anything though! I've no idea whether the car actually drives, runs ok, so hoping to leave the box on the subframe somehow without dropping it right out.
 
Ok an update......clutch master cylinder changed, just lowered sub frame and split the gearbox,. Quite straightforward but took a few hours on my back in the car port. Clutch and flywheel look nearly new:) I must have is disturbed a driveshaft seal during assembly....so had to take the shaft off again and replace :eek:
New back box, rebuild back calipers, new shock, discs and pads. Flew MOT EXCEPT....emission test aborted because 'smoke levels are significantly in excess of the specified limit values (co2 at 40 too high)' aggghhh. It runs like a dream but there's something seriously wrong with the fuelling, no codes showing, hopefully multi ECU scan will find the issue when my cable arrives!!!
 
It's a 2.2 petrol, no visible smoke except what looks like steam until warmed up, i think it's a standard MOT term? It does smell like it's running rich. The not guy did say he tried 3 times to get it through but as you say there's a serious fuel issue here. When I looked at the lambda sensor the signal wires had been pierced for probes so I think I've inherited this problem.
