E153 Filler Plug Help

Hey Guys,
 
I am in the process of filling the gearbox oil ready for the car to go to the dyno on Friday, and I had 1 attempt on it with a size 24mm socket and it slipped. So I inspected the bolt and its already a little rounded so I dont really want to try again yet.
 
Is there an easier way to try and get this out? It hasnt been out for roughly 4-5 years so its going to need a fair amount of effort to get it out.
 
Regards
Alex

Hi Beagle,
I read somewhere that a six point socket should be used.
The only one I could find was a long series one from Repco.
I then ground off the tapered lead on the socket so that the hex of the socket fitted entirely on the hex of the plug.
I can't get my drain plug out & I can't get decent leverage & access with both hands working on the floor.
I reckon that it will be o.k from a hoist or pit.

I just had another look at a pic of an e153, yep the bolt I was thinking of was a six sided nut not square drive :)
 

Do Not disturb that 12mm hex head bolt as it secures the reverse gear shaft.  Big No No.   Cheers.

Use a good fitting socket or ring spanner, load it up and give the end of the spanner/bar a sharp tap with hammer, the shock is usually enough to crack it, much more effective than just using a constant force.
 
You can also fill it through the top but need the normal filler plug out to get the right level.
 
Cheers
 

good work mate
yeah those double hex ones aren't the best and tend to slip sometimes. Single hex FTW!
