  1. Thanks for info. I found a local guy breaking a 300tdi so I got the stub axles, drive shafts and hubs, all in good nick. 300tdi drive shafts would never have fit my 200tdi hubs. I've bought a 24 spline diff from a breaker, when I got it I found it's from a Disco 2. I hope it fits my axle case. I think ratio is same. Dave
  2. Hi, I want to install an Ashcroft 24 spline locking differential in rear axle of my 200tdi. Problem is my half shafts are 10 spline. There has been some previous discussion about using 24 spline shafts from a 300tdi, but apparently the holes in the integral drive member don't match up to the 200tdi hubs. I've heard that there may be a solution by using early V8 Defender 24 Spline Shafts with the thicker drive members. Does anyone know if this is possible preferably with part numbers? It has been suggested I change the whole axle, but I have just cleaned up casings and painted, fitted new hub bearings, seals and discs etc and don't want to do again. Another thought, could holes in 300tdi drive shaft flange be elongated to suit hub? Dave
  3. Thanks C18RCH, this is exactly what I wanted to know. I didn't work out what the two red cages were doing! I'm going to put them in both axles of my Disco. Ashcrofts are selling these units at £50 +vat cheaper than their own Air operated Locker and no other parts required, apart from some new bearings. If these are so good it will probably be leading brand in UK! Dave
  4. I've watched the video over and over but cannot see where there would be engine braking. Fourth diagram is showing overrun of outer wheel on a curve. The motion of of the wheel drive member is forcing the rollers into the spaces of the outer drive member connected to crown wheel. This allows the overrun to occur. So if both wheels are forcing it's respective rollers into the outer member (as in hill descent) then both wheels will overrun and no engine braking. Kaiser do not mention hill descents in their documentation but do state that there will be an improvement in fuel economy Dave
  5. Trying to decide whether to buy Kaiser auto lockers. Has anyone had experience of these? Looking at Kaisers website the explanation of how they work is brief. I understand that when driving straight forwards against resistance (heavy going or uphill), the diff is effectively locked and both wheels on axle will rotate at same speed as crown wheel. When cornering, the inner wheel drives at same speed as crown wheel and outer wheel is forced to "overrun" the inner wheel causing it to effectively free-wheel. If whilst cornering the inner wheel loses traction and spins up to speed of outer wheel, the diff will lock the outer wheel providing traction. All this is fine until a hill descent. It appears that both wheels will overrun the crown wheel and there will be no engine braking? There is no mention of this in their explanation. Ashcroft's recommend installing only in rear axle, presumably to provide some engine braking? Kaiser state that their differentials can be put in both front and rear axles so you would free-wheel down hills or on overrun. Can anyone confirm my understanding is correct as I'm not happy about the lack of engine braking.
  6. Hi, Anyone doing Gatescarth Pass on 4th June or 3rd July? I've applied for permit, but "they" won't issue permits for single vehicles. Maybe I could tag along, only pass left to do. Dave
  7. Hi, I'm doing headlight conversion on my 200tdi. The td5 facelift headlights have levelling motors installed and would like them to work. I have the switch from disco td5 which has connections numbered 1-4 and E1,E2 on it's base. According to td5 wiring diagram only three of the connections are used for levelling. I would very much appreciate if anyone can tell me (or have a look) which are used? The three wires are coloured: Black (earth), Red/Orange (12v supply) and Blue/yellow (to levelling motors). Thanks, Dave
  8. I have a T28 turbo with adjustable wastegate which came from my Nissan 200 sx. I also have turbo exhaust outlet plus 2 1/2" bore exhaust I can modify. I was wondering if I could use it on my 200TDI Disco to replace failing original and improve performance? The manifold flange is the same as standard T25. I'm fitting a boost gauge to monitor boost pressure. I understand that I can increase boost to 1 bar (same as 300TDI).
  9. Has anyone replaced the axle tubes between the diff and flanges? The reason I ask is that after knocking all the rust scale off the rear axle (disco 1, 1990) to weld on new brackets. the tube wall has become very thin and easily holed with the welder I work in an engineering shop and have access to various tube sizes. Is job as simple as cutting off diff and flanges and welding in new tube (same size or thicker wall) to original length and orientaion, provided there is enough clearance for half shafts? I'm replacing all the brackets anyway. Regards Dave
