  1. Hi, just seen this, I think your questions have already been answered but let me know if not, dave@ashtrans.com Dave
  2. Hi, the LT77 for the 200 TDi is not an option from us, the pinions are NLA, we only supply the short R380,
  3. yes, thats an option but a neater job is just to buy the correct R380 as the engine sits in the correct position so no need for bulkhead mods and parts are stock ie hoses and exhaust etc.
  4. not easy, different number of teeth on the pinion so you have to change the layshaft, also usually 1st and 2nd, also I think the V8 pinions are NLA, FRC5834 Dave
  5. I have no idea but it looks like this tool is only used to turn the input gear, FTC5090 will do this too,
  6. or use : https://ashcroft-transmissions.co.uk/product/ftc5090/
  7. I use these too in the workshop, great light and last very well
  8. the kits are put together to order but we are out of some parts at the moment so we have backlog of about 40 kits, hope to start sending more kits out in November,
  9. sorry to be pessimistic but I don't think those gears will dress, the pressure face has totally overheated and gone through the hardening, we dress many gears with die grinders due to burrs from manufacture and small dents from bad handling when soft but the gear in the photo is too far gone I think, it will howl and will get worse as the surface hardening has gone,
  10. Hi Neil, yes thats the most likely reason for failure, Dave
  11. we have V8 pinions in stock if you want to swap it
  12. or the wrong pitch ? look at the top left 8 thread 'peaks', the deformed step on the right flank get progressively bigger as you move to the right, maxing out at peak 8, ie the depth it was screwed into, if you can wait, don't buy anything yet, you might be able to salvage the parts you need from the one I have,
  13. Hi Tim, maybe check those female threads above, shouldn't be deforming the screws like that, I have found an old one of these in the workshop which we can have a look at if you still need some parts, I really dont understand why they use Chinese bearings, to save £ 2 on a £ 1500 item ??? Dave
  14. A fine pitched M22 on the pinion is likely to be a KAM one, I was just concerned it was one of ours and you were using the spacer which wouldn’t be required, I don’t know if the KAM ones used spacers but if it’s built up OK and both side adjuster nuts are sitting OK then that’s fine. Salisbury ATB’s are late Jan / early Feb Dave
  15. is it our ring and pinion ? are you sure you should be using the spacer ring ? Dave
  16. Wow, brilliant work, and thanks very much for sharing this info, Dave
  17. Why don't Ashcroft or Syncro use thermostats in their coolers? cost / more complex to make Can you overcool the box? I dont think so The Syncro one looks identical to the Ashcroft one but is more expensive. we were making them first, if you want one with thermostat we have used genuine @ £ 60 + V ea
  18. We decided to make some about a month ago, will be available in about 3-4 months,
  19. they are the same, its just the short R380 one thats about 5mm shorter Dave
  20. the bush ID is too small on the britpart ones, we fit them to the stub axle then kiss the ID on a lathe so the CV drops in nicely Dave
  21. Yes we can fit it for you but if you want to keep the cost down you can get 90% from a MOT failed disco and just buy the Compushift, you can then either make your own interior or we can supply later as the budget allows
  22. Hi Guys, a small tech thread to show you what we have been upto for those with the 6BT Cummins engines, this is meant as a non commercial technical thread to show how flexible the LT230 can be. features are : 0.900 Ratio, we have been aware for some time of demand for higher gearing for these low revving engines so after successfully making the 26 Tooth input gear for Reece to run with the 1.003 ratio gear set, we looked at how we could do this. Land Rover raised the ratios in the LT230 by reducing the diameter of the output gear but it was not possible to do this further as the 1.003 gear is already quite small and reducing it further would not be reliable so we made a new larger diameter input gear with 28T instead of 26T and this also allowed us to raise the output gear from 28 to 30T which helps strength. This gives an increase of 10.27% on high range. Increased width of gear teeth on the input gear and corresponding intermediate gear. Rather than leave wide air gaps between the 3 rows of teeth on the intermediate gear we have increased the width of the input gear and middle row of teeth on the intermediate gear by 4mm from 32.50mm to 36.50mm. Bigger bearing on high range side of intermediate gear. We have seen failures in the past of other brands of these input gears and I suspect these failures are related to the taper roller bearing in the intermediate gear failing on the high range gear side which then allows the intermediate gear to move out of mesh with the input gear teeth and the teeth then fail. We have machined the intermediate gear on the high range side to accept a 62mm diameter x 25mm wide bearing rather than the stock 52mm diameter x 22mm wide bearing. The bigger bearing has ratings of 64Kn Dynamic and 76Kn Static as opposed to the stock bearing having 54Kn Dynamic and 56Kn Static. This bearing (Timken brand) is supplied with a sleeve and spacer which are required to fit. See 'install' ref fitting notes. Please see below comparison of the standard bearing and the larger bearing supplied with the kit we are really quite chuffed with this, its taken about 9 months to get made and needs long term testing but the gears are from a proven supplier and gears are stronger than the 1.003 ratio which had no failures so I don't anticipate any issues, full blurb here : https://www.ashcroft-transmissions.co.uk/0-900-gear-set.html Cheers Dave
