  1. Well, sadly, the solenoid service has not done the trick. Dave Twigger at Overdrive Spares has suggested that, because the symptoms are relatively mild, it could indicate that the oil pressure in the overdrive may not be helping the cone clutch engage sufficiently and he has sent me some shims for the pressure relief valve. I hope that the use of EP90 hasn't caused contamination of the friction surfaces as, apparently, Laycock specifically stated that it is undesirable whereas Triumph recommended it for the gearbox. A bit tricky to heed the advice from both organisations! Hey ho
  2. I had a similar problem. Re-calibrated and reconditioned speedo stopped working. Checked cable and it was perfect, so I checked the angle drive. The remains of the square end was stuck (brazed) in the angle drive with a few wisps of cable remaining. The new cable had been inserted and tightened as a friction fit and it actually worked for 7000 miles. We (John Morrison and I) decided to ditch the angle drive and a longer cable was purchased and a hole in the chassis was relieved slightly to allow the cable and nut to pass through. It works and no pesky angle drive to worry about
  3. My TR4 was fitted with a Powerspark high energy distributor when I bought it 7000 miles ago. It developed a slight misfire and I thought the distributor was faulty and I was going to be in for a large bill. After discussions with Powerspark I discovered that the Accuspark 3 ohm non ballast sports coil (red) that was fitted by the previous owner was a mismatch and they recommended fitting either a Lucas DLB198 or a Viper dry high energy coil (.8 ohm). I went for the Viper, a little bit dearer but the difference over the Accuspark is quite remarkable and the misfire has completely disappear
  4. That's what Peter and Dave said. A good clean and new 'O' rings should eliminate the solenoid as a suspect. Fingers crossed that it solves the issue which, I might add, is not causing me any problems under normal running, only when it got very hot climbing lots of hills and giving it a bit of stick. Andy
  5. Put it into normal drive on run. When the filler plug was loosened, oil ran out. Can't add any more. In running the overdrive engages and disengages quickly and smoothly every time on the switch and was tested using a meter quite recently when we were modifying the overdrive mounting plate - belt and braces.

I believe they do several models) then I can't recommend it highl
  7. Both check out ok. First step is to service the solenoid. 'O' rings in the post! If that fails I will replace it. If that fails it is o/d out. Andy
  8. Thanks everyone for your suggestions. I have spoken to Pete Cox who had been looking at this thread and also Dave Twigg at Rugby. Both were extremely helpful and both felt that the first port of call should be the solenoid. It hadn't occurred to me that the solenoid could cause these symptoms. I certainly hope that this is the case as it will be a lot more convenient to replace that than anything internal and probably a good deal less expensive Andy.
  9. Well, I've been out on a test run and I'm pretty sure that the clutch is ok. It instantly stalls when letting the clutch out in 1st and reverse before and after a run. No probs at all in normal drive but I failed to induce slipping when I tried putting it into overdrive though I was a bit limited by traffic and the only hills being in a 30 mph zone. I'm not sure how long it takes for the gearbox oil to get up to temperature. My concern now is whether I am likely to do any damage if I avoid overdrive or whether it makes any difference. I have a charity run coming up in 9 days and taking pa
  10. Thanks Rich I hope you're wrong. I'm going to try some tests today like releasing the clutch while holding down footbrake, seeing if I get any slip if I don't engage overdrive at all, seeing if there is any difference whether hot or cold. If it is the unidirectional clutch in the overdrive maybe changing the rollers alone would suffice although that would be subject to inspection. That would save a heck of a lot of cash but would be a pain if I needed to strip it down twice Andy
  11. I have just read this thread elsewhere about a J type overdrive slipping which is a little alarming. https://www.clubtriumph.co.uk/forums/topic/1660-clutch-or-od-slipping/ I'm going to have to take the 4 out again and see what I can induce (or indeed deduce!). Any suggestions as to a logical process of testing. Finding an empty road on Bank Holiday Monday could be tricky. Andy
  12. Fingers crossed that it isn't the overdrive Andy
