What you can also do is to change the fill plug for a Citroën / Peugeot one for easier replacement and removal afterwards. See:

As I was afraid, there are no shortcuts to unscrew the old oil filler cap:(.
Thank you for your help!

According to John Reid of Grantura Engineering use only Morris Lodexol XFS 80W-140 as no other oil has the additives required for this type of differential and also change it every 5000 miles. At the moment my diff refurbed by John has Castrol in it but I will be changing it as soon as I get the correct oil. The diff is now unbelievably quiet with no clonking

I've heard that in Australia, car services use CASTROL SYNTRAX 80W-140. It is a country where they produce a differential. I hope they know how to service it.

Have a look in the INDEX Artur.

Arturo I did that this month,

Jack rear of car up using my 3 ton trolley jack on the tow ring at centre of back underneath. Inserted axel stands under rear jacking points on the sills. Let jack down slowly so the stands take the weight. Lock the jack off just in case the axel stands dont like it. Placed my 2 ton trolley jack just to one side of the diff say 3 cm off centre to the left said as looking at it, Put a piece of 25mm thick wood across the jack lift pad so it allows the diff frame to take the strains and not the cast itself on its own. Jack the whole diff assemble about 8-10mm only.

That allows the 29mm socket to engage with the bolt head which is really easy to undo like it wants to come out, That is due to the plastic washer. The above mentioned Cortico part ( a peugeot gear box drain plug) 22mm thread with internal ( female ) hex socket in middle 12mm. The new plug is quite loose sitting on my finder tip with a finger down the side but it engaged easily and the fingers twisting were enough to get the thread to engage then the 12 mm allen key sorted the rest. I used the supplied copper washer and then tightened down to firm not wrist breaking tight as your going into a casting. Gently let the 2 ton jack down and removed it from the scene and then used the 3 ton to lift and remove axel stands. Sorted. Time almost ten minutes.

hope this helps and others dont remember a much easier way or I'll...??.

Good evening
For filling the differential With an electric engine oil drain pump I filled the oil through the drain hole with a pipe of the diameter of the drain hole once the right amount. I hurried to put the drain plug back Sincerely Yves

A really interesting thread but I am unable to view any of the attached links? Any mod out there can you help please. You need to be a full member to see a lot of the forum information. Those links you refer to are probably in an area only for full-members. You can ask for a questionaire and apply to be a full member. You will need to become a member of the MGOC, if you are not already a member though. There are no extra fees for the Two-Sixties then, Sent a private message to 'Tim' with your email address, and ask him for a questionaire.

As David says you need to become a full member to view the vast majority of the posts on the forum Nigel. If you have a 260 and MGOC membership then send Tim a PM asking for a new questionnaire to get full membership. It's about time you've been 'lurking' for 6 years!

I quite like this solution. Good lateral thinking!
