Shame about the plug, Geoff, not something that even crossed my mind because as you say later diffs have the vertical plug. On those the hex of the plug is still below the level of the rest of the casting. 

I wonder if there's a mag plug with an Allen key socket, if that would give you clearance?

Now I have a bit of spare time on my hands I thought that I would clarify my reply to Billy.Whizz about the info that was given to him by CC regarding the BMW/Titan diff.

Quote:

1) #378 - 'Recently a member of the MT asked G. Mac about any problems with the titan diff and his answer was, you have nothing to worry about.'

2) #408 - 'Geoff I'm only stating what a member of the management team told me in an email and my question to him was about the current titan diff, he got that answer directly from G Mac when he asked him a few days after the webinar evening with CC.'

In both cases the comments to a certain degree are misinformation & an untruth.

The 2016> & current BMW LSD should be fitted with sintered plates then yes there is less to worry about but the situation still remains that the Titan will require health monitoring & a refresh every 10000 road miles in accordance with Titan's own recommendations. Inevitably due to the Titan design the Belleville springs may possibly fail under 100% compression well before the service is required. The shrapnel likely to cause internal damage. In fact James B's Titan is a lesson in catching it just in time for a 2012 unit with only 7000 miles.

The <2016 BMW LSD will be fitted with carbon faced plates which as we all know from discussion here can be prone to accelerated wear & the break up of the Belleville springs which potentially cause catastrophic internal failure. So in this case there is more to worry about !

Another worry is that CC naively considered the BMW/Titan a 'fit & forget' unit even though Titan clearly published the service requirements. CC have never published the service requirements for the BMW/Titan which leaves owners to find out the hard way spending ££££ to rectify the problem.

IMO the only way out of this problem is for CC to come clean, publicly admit the mistakes made & publish the servicing recommendations. Any time soon on that count. Trouble is I do not expect the slightest hint of contrition nor any financial recompense for their error.

I see the Titan problem as the largest automotive Iceberg in history with CC balancing on one toe above the very adjacent water line.

Hi Geoff ,

Glad the new LSD is as expected, what is PIO please?

PIO - Pilot Induced Oscillation - sorry an aviation term for the plonker cannot keep steady on the controls or in my case feather touching & letting off on the throttle at very low speed causing a bit of drive line shunt but not kangaroo hopping.

#413 Geoff, even Titan's servicing recommendations aren't adequate, many of the known failures have been well under 10,000 road miles. 
 

But 'largest automotive Iceberg in history'? I'm not sure it's that bad...... Wink

'even Titan's servicing recommendations aren't adequate'  They would be adequate if the Titan was engineered better & not built to a budget. Oh & CC were honest about the servicing requirement in the first place. 

Hopefully those of us who went another path will not have to worry about servicing every 10000 miles or 2 - 3 years.

Well, yes but then we wouldn't have this thread in the first place! Wink

But I do agree with your last point. Occasionally, because most of the time I just don't think about the diff any more when I'm out, I start to wondering if the SPC is still working, it's so quiet; then I floor the throttle and it reassures me..........

ScottR400D - Yes, the Tracsport is so eerily quiet !  The only way that one knows it is working is when attempting a challenging corner on a Wiltshire B road at a higher speed than one would with the Titan in place. Serenely drive round with out a drama or crisis.

I have just had a local member drop off some borrowed tools after re fitting a BMW LSD to his R300D. He opted for the Tracsport & he is just as amazed.
