Caterham 7 R300 Superlight
Discussion
So update on the new Tracsport LSD.
I got the diff back from Steve at SPC after about 3 weeks. There's two ramp angles you can choose from after a lot of discussion I went for the less aggressive 30 degree ones which should give good behaviour on both road and and track. The state of the old Titan was a bit of a shock....this was the state of the carbon clutch plates
Not much carbon left
And this was the state of the Belville washers, well at least the bits that could retrieved from the diff case.
This had caused a lot of pitting and damage to the case of the Titan and shows how much metal was floating about!
I managed to get away without any damage to the Crown Wheel and Pinion which was pretty amazing, all things considered. Anyway, as the Haynes manual says, fitting is the reverse of disassembly and with the Caterham build manual for backup, it was pretty straight forward to rebuild. The most difficult bit was actually getting the diff to slot in to it's cage, the tolerances are very tight, but the jig I used to get it out came in very handy and with help of my son on the trolley jack we got it back in in around 45 minutes.
All in, and bolts torqued up!
I elected to buy the new, upgraded 'sealed for life' rear wheel bearings and all new shiny nuts, bolts and washers so these went on during the rebuild.
Finally, everything was given a good clean and the bolt torques double checked.
And that was it, all back together just like a big Lego set
I've now done about 150 miles and it feels absolutely amazing. It will break traction at the rear quite easily (I think I need to adjust the rear ARB as it's quite aggressively set) but it feels so much more predictable and less 'snatchy' than before. Given the state of the Titan though that's not really a surprise! Next up is to get some more miles on it once the rain stops and then get it back on track.
