Hi all, thanks for the recent advice from a few weeks ago. I have since then taken out the gearbox and transfer box etc.

The roll pins had broken!

I have replaced the dmf with a second hand one, mine moved easily 3 teeth and the 'new' one moved just over a tooth.

replaced the clutch.

Fitted a 2nd hand gearbox with less miles and hopefully quieter.

Refitted the neutral blip by switching it around and fixing in place with a roll pin.

On the clutch part I managed to 'double roll pin' it by putting a smaller roll pin inside the bigger roll pin.

My only amateur mistake which could cause problems later was adding grease to the input shaft and pressure plate bearing. Now worrying this might get on to the clutch.....

Still have to put the centre console back and not sure I have all the air out of the clutch but will bleed again but I did drive it around the block at about 11.30 last night.

The other mistake was taking out the bell housing with the gearbox but did take out the gearbox and transfer box separately.

Putting them back in was a struggle just tried lifting on trolley jack blocking up and lifting again, spent about 3 hours doing this to no avail.

So built a little cradle lifted the cradle, supported put on a greased plank and then lifted on three jacks to get the height and angle required. Worked well for gearbox but was more of a struggle with the transfer box and needed two of us and a ratchet strap to pull it forward.

It has taken about 30hrs with a couple of hours help from a very good friend! I ache like I have been through a mangle.

Must have tools included a set of wobble extension bars, my 1/2" torque wrench used more as a breaker bar! And four jacks and axle stands. And lots of wood. (Would also be useful for burning should it become necessary!

Hope what I have done helps someone else, either by getting someone to do it for you or to see what you are taking on!

Yes, it's a fun job, had to do it myself for the same reason (stupid roll pins) I found it easier, my trolley jack has a larger jacking pad. I had no problem with replacing the gearbox, just had to hold and push the transfer box whilst I jacked it up with my leg.:)
 
Doing it with a toy jack was a real feat of endeavour. :D:D

Yes it didn't help but couldn't easily get hold of a proper one over here..... Also been for a short drive this evening, fingers crossed all seems good. Clutch seems much easier to operate, bleed the brakes as well and peddle seems much firmer but I am going to take the tools out of the car tomorrow!
 
Hi Zen, thanks for the reassurance, and tomcat59alan that was what I was hoping would be able to do: full respect.

Yes, the clutch is easier when they have been replaced and the pivot cleaned and lubed. No need for a Charles Atlas course for the left leg as has been suggested on this forum. Pity there isn't a couple of grease nipples for the pivot shaft.:)
 
At least he had a trolley jack, did a Classic once in France with only the car's jack, now that was fun (not).:)

Is yours one o dem labour intensive manuel fings den Alan. Bloke who vented dem must have been from Madrid dem bein manuels an all. Automatics is best they change gear without you havin to take your phone from your ear. Pure luxury. :D:D:D

That's a bl**dy good effort. On a trolley jack too - real hardcore. I had fun getting it all back in with a four-poster and a transmission jack. I think you should give yourself a damn good pat on the back and a couple of decent beers too. Well done.
 
Top effort, I changed an auto tranny (with transfer box) on a Cherokee, first box was U/S so had to do the job twice:eek:

I used two trolley jacks to get the angle right and pulled the whole lot together with a ratchet strap fastened to the front crossmember below the rad. I took a day to remove and a day to install, pass the Radox and the Nurofen.

It's amazing what you can do with sheer determination.
 
Thanks Grrrrrr and wammers, I think. Couple of beers consumed with pride and relief. Just bought the oil for an oil change then on to Missus merc to do the prop shaft support bearing, diff oil seal and brake switch (ABS related).... Still wouldn't buy a small current newish car though but I wonder how long they can be kept going for though?
