Differential Wanted!!

[ColinE]

Depending on price we could buy two or three, one could stay with Phil up north and one with either me or Justin in the midlands & south. Boils down to cost if we blow our bunce on two or three high cost items we would need to build up the reserves again. Where do you stop props/subframes/engines?

Perhaps the best way is to identify 'friendlies' where we can get our hands on the bits. In the long long term I would be trying to get MGOC to position themselves to cater for our needs like they do for the classics.

I agree with identifying friendlies and trying to secure more support from the MGOC, especially when seeing ads in Enjoying MG that state ' We stock all MG parts' - something that is clearly not true.

I Had a chat with Mark Longmore today, ha cannot supply new diffs but do not worry if yours needs fixing, the chap at Grantura Engineering is the main man in the country for the repair of these, he rebuilds them as standard and with different ratios etc. for Morgan and Marcos ( whom they still supply ) TVR's etc.,
they were the same as ours apart from the ratios and parts will always be plentiful

The oil is critical in these, only 3 makes can be used ( see previous post) they spent £ 25000 signing off these oils, many others were tested but failed, the diff is robust but you can get problems if repeated ( 25 or so ) 0- 60 runs are carried out as they get hot and the oil takes a pasting with little free flow of air, if you do track days change regularly .

as for the ones that came from the factory Mark Longmore had a look at these as the receivers wanted them to buy them back !! there were 30 or so but some had appeared to have been dropped so they backed off

When these diffs were new an additive was added that contained phosphate to help run them in, this should have been changed at 1000m ( has yours been changed ?? ) then any swarf ect gets changed and you can then leave it in for 60K miles

Mark sees many cases where so say specialist gearbox & diff repair centres
try to repair and set these up and get it wrong, also using other oils that are good in other aplications and tell you marvelous things on the label but not good for our cars, Dreadnought also sell the correct oil I believe.

Tim, just realised the last post should really be in the Engine / G Box section
is it possible to place it in there as well ???

[ColinE]

Dreadnought also sell the correct oil I believe.

Indeed they do, changed mine and it made a big difference, took my Dad out in mine at the weekend and he noticed it was better

My 260 is back on the road!

With many thanks to Ian and his staff at Bespoke Auto Developments, I have a new and serviceable diff fitted to my car. Now for the running in process (something I am sure most of our cars never experienced!!) according to the MG Rover supplement manual for the 260, the cars diff should be run in over 500KM (312 miles in English) and speed should not exceed 100 KMPH (62.5 MPH) and a constant speed and max revs should be avoided. Now convince me that our cars received that treatment when new!

[ColinE]

So are you taking bookings for rear subframe overhauls???

Glad to hear you are back on the road

Well...... This time I lowered the whole "stuff up" assembly, and it took me about 40 minutes from start to finish. Re fitting took just over an hour!
I've done it several times now so practice makes perfect!

I for one think that its worthy putting on the record that credits due and a virtual "pat on the back"for tackling such a major undertaking especially on your drive single handed!,well done .

thats great news! So yours could be one of the very first to actually have it's Diff run in then?
