Leadership Team Shortshift Posted July 7, 2020 Leadership Team Share Posted July 7, 2020 Hints and tips? Removing the diff to have a longer (3.14) ratio installed. All part of my quest to change the car into a miniature Bentley Conti GT cruiser...James Link to comment Share on other sites More sharing options...
Doctor Posted July 7, 2020 Share Posted July 7, 2020 It is quite tight, best done on the ramp with two people. From memory mine had two right sided drive shafts. Link to comment Share on other sites More sharing options...
MADMALC Posted July 7, 2020 Share Posted July 7, 2020 You may want to consider removing the hub, brakes and drive shafts as one complete unit. Make sure the speed sensor wire is not still attached!!!!! It is a heavy lump so easier if two of you can man handle it. Link to comment Share on other sites More sharing options...
Tazio Posted July 7, 2020 Share Posted July 7, 2020 As MadMalc says, easiest way is is to remove the hubs and driveshaft as complete units. Remove the calipers and tie wrap them out of the way. Take care when you pull the driveshafts out of the diff, don't simply pull on the discs because if the diff end of the shaft doesn't immediately come out, you can inadvertently extend the outer CV to past it's limit and you could displace the internal spring, so pull both ends of the shaft together.On a de dion, if you disconnect the radius arms, and rear shocker bottom mounts, you can push the de dion back to give you more room. Maybe you haven't those restrictions on the CSRTake loads of pics of the mounts, to ensure you have a record of the number of spacer washers used.Dropping it out and putting it in s easier with two people, more hands to keep the diff level on the jack.

7 wonders of the world Posted July 7, 2020 Share Posted July 7, 2020 no reason why the shaft hub and disc cant come out as one, disconnect lower coilover and remove wishbones to upright mounts.looks like theres more access to the prop bolts than on an S3 !Are you getting Steve to pop a Tracsport in the new final drive before it goes in..?Tazio - on a Dedion theres no need to touch the radius arms or lower coilover mounts, drop the A frame and zip tie the tube back to the chassis thro the centre mount - final drive drops straight out then.

richardhomer Posted July 7, 2020 Share Posted July 7, 2020 Be prepared ! Lots of sweating and swearing. Definitely a two man job. Worst part is lining-up and getting the diff mounting bolts back in. Good luck Link to comment Share on other sites More sharing options...
Tazio Posted July 8, 2020 Share Posted July 8, 2020 Neil, for the sake of undoing 4 bolts to get the de dion out of the way,it's a no brainer, it gave us so much more room, and remember I've got 20 more odd years on the clock, than you, so I'll take that advantage.

Leadership Team Shortshift Posted July 8, 2020 Author Leadership Team Share Posted July 8, 2020 So it seems the consensus is:1. Find a strong, fit, handsome assistant (luckily, Simon M has been voluntold for this, and he meets most - though perhaps not all - of the criteria)2. Disconnect the wishbones (both upper and lower, or only one of them?), disconnect the tie/toe-control bar and withdraw the hub/hub-carrier/rear calipers/driveshaft from engagement with the diff as one unit (the calipers on on flexible lines so give a fair bit of free play)3. Disconnect the propshaft flange joint and, with the help of the glamorous assistant, unbolt the diff from the chassis (very different from a S3 car) and lower either to the ground or onto the soft, squidgy, flesh-coloured thing underneath.I think that makes sense. It does look a bit tight, though, to drop the diff between the various chassis tubes - but I guess it must go through somehow.Neil - I managed to speak to Steve (after not getting any response to emails) and, to be frank, I got the impression he wasn't interested. Not what I expected, given reputation and so on, and disappointing as he's only eight miles up the road from me. On the other hand, R&R have been very responsive. Guess where my business is likely going...James Link to comment Share on other sites More sharing options...
Yorkshire NE AR Posted July 8, 2020 Share Posted July 8, 2020 Don’t forget to disconnect the speedo sensor cable as MADMALC mentioned. He should know, he was there when we didn’t manage it! Rewiring the sensor is an added irritation after wrestling with the diff mounting bolts. Link to comment Share on other sites More sharing options...
7 wonders of the world Posted July 8, 2020 Share Posted July 8, 2020 I'd pop in and see Steve, usually works best.Which LSD are you having though James...? Link to comment Share on other sites More sharing options...

Doctor Posted July 8, 2020 Share Posted July 8, 2020 This speedo thing is a bit strange - my CSR R500 had a R500 SL Stack dash and the speed sensor was on the front left wheel. Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted July 9, 2020 Author Leadership Team Share Posted July 9, 2020 Neil - I don't want an LSD on the CSR. Happy to leave it open for cruising and fast-road use.Igor - yes, the Stack on my R500 uses a front wheel speed sensor but the CSR (and many others, including your 620, I suspect?) pick-up off a toothed wheel at the rear.James Link to comment Share on other sites More sharing options...
Doctor Posted July 9, 2020 Share Posted July 9, 2020 I see, need to check that. Link to comment Share on other sites More sharing options...
