Sump removal

[andyverran]

Folks, need to pick your brains...

best/easiest way to remove the sump?

Since the wishbones look good and should all be back together tomorrow (I hope it doesn't rain) I figured best to get on with the sump before Autumn arrives in force...

I had a little google round and dropping the diff keeps cropping up. Has anyone done that? I had a quick look and I'd guess if I drop the ARB and undo the 4 bolts holding the diff cross memeber in I might get it down enough. Anyone know how much I can safely drop the diff before I break stuff?

I tried to drop the steering to get access to the sump bolts on the off chance I could find a way to get the sump out, but everything I touch is very rusty, couldn't split the joints on the steering so that plan is done and dusted.

Dropping the diff is pretty easy - undo the 4 propshaft bolts then jack up each side on the lower balljoint so the suspension compresses. Stick a socket or some wood or whatever in between the upper bumpstop and the top arm then drop down onto axle stands. Undo the inner driveshaft nuts then undo the 4 12mm nuts on the upper balljoint. Now you can drop the upper balljoint and swing the hub forwards enough to pull the driveshaft off the diff.

Then it's just 3 bolts, 2 electrical connectors and a pair of vacuum tubes.


Really is no bother, just a bit of time.

I've got to swap my front diff soon. (have changed the rear ratio)

Cheers for the info...Once the suspension (left side now) is back together I'll take a look at it...a few days after the rain stops!

It looked like a battle to do when i lay underneath it, put me off a bit!

Nice weather today, so dropped the diff, bit of a faff with my dodgy wrist and I did leave the drive shafts attached...but I can now see the sump at least. Tomorrows job to get it off.

After some rust removing...found the sump leak...and a few other patches that might be thin enough to weep oil.

Gasket on my Gen 3 is ####ing oil, I think I've got to do this... Great post -

Tom,

When you do it ....

The gasket goop as a bit of a pain to put on, (if only it was a normal gasket) as you have to lie on your back an reach past the bottom end.

18 bolts on the sump (all 10mm) but you need to remove 2 bracket that join the block with the gearbox (4 x 17mm) and a lump of foam and a plate that covers the flex plate access.

I had tacken the left lower wishbone out the week before, so I knew the bolts would undo easily, hence I dropped the crossmember (4x17mm) with the diff attached, having undone the 2 large mounts to the chassis (2x19mm - they were f***ing tight), disconnected the vac hoses to the diff (x2) and the wireing (x2 connectors).

That lot let me lower the diff just far enough (like I had an inch to spare) to get the sump out of the back. PS disconnect propshaft (4x14mm and easy to round off if using a bar as access with sockets is not ideal near the UJ).

I know that's not gen 3, hope some of that is in some way helpful.

Oops, forgot to say, on a gen 2 at least I needed to drop the steering damper so the sump could come down at the front to clear the crank.

Sod that it can carry on ####ing oil!

Lol - thanks though, too much faffing with things I can easily break!

Its not as hard as it sounds, I was put of to initially...I just did one bit a day till it was off, nice easy targets then for each day.
