Hi All

Can you remove the fuel tank from an 82 2ltr 924 without having to drop the transmission?

Please say you can with tips!!!!!

Cheers

Ben

Unfortunately, from what I've learned only the 1980 924 with the Snail shell transmission can have the fuel tank removed without removing the tranny. I have a 77 and just removed the fuel tank and there was NO way that was coming out without the tranny being removed first.

Someone else can chime in with something I forget.

This is what I ended up doing, YMMV.

1) Remove the final muffler assembly. Three bolts at the connector, and then four more (I think) along its length for support. The whole thing should drop at that point.
2) Next I dropped both axle shafts. Make sure you mark then Left and right and which end is in-board and out-board. This will be useful when reattaching or rebuilding. The axles are held on with 8mm(I think) triple square bolts. These are a special tool but you should be able to find them at a FLAPS. These bolts have a tendency to strip so take the drive and tap it in with a hammer, then attach the socket to loosen.
3) Crawl under the car to the front of the transmission and there should be an access hole. Remove the cover and inside you should see a coupler with two hex bolts. Remove both of these bolts and then slip the coupler into the transmission side of the shaft.
4) While underneath there, on the top of the transmission remove the shift linkage. It should have a rubber boot over it. Remove the boot and there should be a bolt that you can remove.
5) In the cockpit, remove the shifter cover and then remove the small C-Clip on the shift lever. Pull off the shift rod, rotate it about 90 degrees and slid it forward between the foam and the top of the hump. You need to slid it forward about 8 inches or so.
6) From the back of the transmission, remove the reverse light plug and then switch.
7) Now remove the four bolts connecting the transmission from the torque tube housing.
8) At this point the transmission is hanging by two bolts located on either side up top. This part can get hairy and it's helpful to have a friend help. Position a jack under the transmission. The balance point for the transmission is a the big flat spot. It doesn't look like it should be, but it is. While your friend mans the jack undo the two bolts and then lower the transmission to the ground.

At this point the fuel tank is an easy drop.

This is my recollection of how I just removed mine. The best thing to do is do some searches on this site and to go through the steps in the Haynes manual and/or Factory Manuals

Good Luck!

The most important thing to do when removing the trans is to remove the coupler FIRST before you do anything else. You have to completely remove both pinch bolts from the coupler. Take them ALL the way out and lay them on the ground or in a magnetic parts holder. Once you've done this, you should be able to slide the coupler toward the back of the car onto the input shaft of the gearbox. Do NOT slide it forward onto the driveshaft. Once the coupler is completely onto the input shaft, the rest of the removal process is very straightforward as described above. Dropping the trans is actually quite easy, I can do it in about 20 minutes or so.

Once the trans and exhaust are out of the way, the hardest part about removing the fuel tank is getting the electrical connections off because they're pinched in between the top of the tank and the underside of the hatch area bulkhead. In your case, you may not care about preserving the wiring harness, in which case, you can just cut the leads and yank the tank out.

Ahh, yes Ideola, forgot about that part because I did it last fall. In my 924 if you lift the carpet in the back there should be a rubber plug. Under the rubber plus is the fuel sending unit with three wires. Remove those wires and I didn't have any tangle up when dropping the tank.

I'll also add before you drop the tank make sure you drain it as best you can to remove any excess weight. I did it by removing the fuel sending unit and using a hand pump to pump all the old fuel out.

Did you slide the input shaft coupler back onto the input shaft of the tranny?

Yeah you have to get that coupler ALL THE WAY back towards the back of the car for it to drop. Reattach the bolts hold the tranny to the bell housing and the bolt into the car body. Then slide the couple to the rear of the car as far as it can go. Then remove the belts and it should be able to drop.

This just made my entire day. I have the snailshell transaxle on my 80 turbo and i need to get the fuel tank out and refurbish it badly. Can you explain exactly how to get it out without dropping the transaxle please?

So far i have the back portion of the exhaust removed and everything disconnected from the tank but it just seems like its so tucked up in the beam thats apparently a part of the body, i've tried man handling it a little but decided to do some research before going to crazy, thanks.

I have a '77 and have never removed the fuel tank in an '80. I do have a couple of questions though. What have you done on the top side of the tank? Is there filler hose disconnected? Can you get an idea from wiggling where it is hitting/catching?

I have the filler hose disconnected from the top, as well as the vent hose? i think thats what it is at least, and i have the fuel level sender removed as well, thats about it for the top side. From the bottom i removed the 2 straps and the exhaust+heat shield. Also the fuel return like is disconnected as well as the pumps. tomorrow i'll try to get some pictures up to show what i'm working with

From what im seeing from beneath though is that the transaxle isnt even in the way, its just the whole fuel tank is so crammed in between body panels it makes me wonder how they even got it in. I cant pull it to the back of the car because the spare wheel body compartment is right there, and i cant go up because its already maxed at the top, but i cant pull it straight down because just ABOVE the transaxle but below the fuel tank is a beam thats a part of the body. Actually i'll just suit up and go take some pictures, maybe even tug on it a little.
