Disco 2 Service Questions

There is no underbelly pan on mine - at least | nothing that gets remotely in the way of removal of the sump plug.

Does that just screw off? | | Very grateful to anybody who takes the time to answer any or all of | the above. | | Regards | Rob

Rob,

OK. Went to the local dealer on Saturday afternoon when they were closed and crawled under a few cars on the forecourt. As a result I can report that all Discoveries built for the Australian market do not have the underbelly pan mentioned in the workshop manual.

Secondly all TD5 automatics (including the brand new ones) have the threaded hole in the torque convertor housing on the right hand side of the small circular plate - the purpose of it remains a mystery but at least nothing has fallen off mine. The V8's don't have the threaded hole so they obviously have a different torque convertor housing.

Still trying to find a bit more detail (than that provided in the manual) on changing the diesel fuel filter. Rob

Answer to 1 question

The treaded hole is for fitting a tool to hold the torque converter when removing the gearbox

Pitter Patter went the keys,, p@?.?.invalid enlightened me...

Is this a windup? Or is there really such a tool? And where does it attach? And how do you fit and remove the tool? If this is true (and if it is I'll be first to say mebedmescepticmesorry) I'd better find another hole to fit wading plugs to....

On or around Sat, 22 May 2004 23:49:45 +0100, weallhatebillgates enlightened us thusly:

There's a big round hole in the bottom of the auto bellhousings with a cover (in theory) on it. This lets you get a tool (I use a very big screwdriver) in to hold the TC still while you unbolt it from the flexplate. Then when you pull the gearbox you don't pull the TC out of the front of it.

This is better than leaving the TC bolted to the engine, as it's hard to get to to line up and go back together, also, it lets oil out of the box, 'cos the seal works on the shaft part of the TC.

however, the threaded hole is AFAIK for the wading plug. Mind, the TC unlike a clutch is sealed and so water getting in there can't do much harm.
