  1. I would have expected your tales of woe on the internet would focus Greenmech's thoughts somewhat if they wish to continue sales abroad, and no, blaming the problem on a warranty issue with the engine supplier cuts no ice.
  2. You need to be a bit more specific about the rough running symptoms, you have said the glow plug light is flashing, is this as soon as the engine starts? When it is running rough does the engine idle and pull okay up to about 2k rpm and then cuts out? If this is so that is switching to get you home mode after a fault is detected. With a bit of care and thought, on flat ground you should be able to smoothly go through the gears keeping the revs below the trigger point and get up to a decent speed in top. It should have raised a DTC (diagnostic trouble code) though.
  3. I only order small amounts of epoxy for carbon fibre repairs but the firm I used (5 years ago last) https://www.easycomposites.co.uk/#!/resin-gel-silicone-adhesive/casting-resin/glasscast-50-clear-epoxy-river-table-resin.html
  4. Did he just check the DTCs. If it is a pump problem you may need to run under the real time to see the rail pressures.
  5. So you have imperial AF bolts, how about Whitworth? I keep a full set of Imperial spanners for my tractors.
  6. That takes me back when I started taking things apart
  7. Lesser celandine in the bottom picture too. I noticed wood anemones today but was driving so no photo. Interestingly the wild garlic was not in flower yet.
  8. I wonder if Windsor Bandsaw still do chipper blades, they used to do mine and not that far south of you.
  9. The bin men are in a difficult position, they cannot walk all the way and often don't have driving licences to get close in their own cars I'm still feeling we haven't been told how this virus is so deadly to people in constant contact with ill people, I'm thinking of medics but now also bus drivers, the level and intensity of exposure seems very significant. BTW I was out of my home for the first time in 2 weeks today replacing a hose on one of my tractors that had burst when the chap borrowing was operating it. My most risky contact was picking the new hose up in the dealer's yard where the fitter dropped it well away from me.
  10. Do you have a special reason for saying this? I agree especially if under glazing plus as fan power is a function of volume times pressure cold air would draw less power.
  11. How I wish I could hear song thrushes in my garden again.
  12. Mk6 has the 2.4 duratorq common rail IIRC. The flashing glowplug light relates to low fuel rail pressure. We had to replace a few pumps at about 120k miles.

  14. Looks like a replacement is available for £450 inc VAT

  16. from what @Squaredy says I suspect it was not the main engine Many generators were just standby and didn't run a lot so the Mawdsley may be a sensible buy, it depends on how much you need to run the saw. Also consider there will be a lot of heat given off which could be used to dry logs. One thing I do know from having installed a Petter genset for a remote school classroom was the conversion efficiency goes down a lot at low power levels. My guess is it needs to spend most of its time at 70% load.
  17. How many wires run to the transformer? I think you mean 11kV. The nearest mill to me had a 54" Stenner and a 48" resaw and that ran off the engine from a Uboat.
  18. This makes good sense although you will need a good run of 3/4" pressure hose though the return hosewill be cheaper
  19. I have never measured the temperature but the handles get warm within a bout 30 seconds. I'd guess about 40C They're a godsend when you have wet gloves and you are cutting for the chipper but I too don't keep them on very long when working hard.
  20. Yes 5kW is the maximum a 5kVA genset will output but this is into a purely resistive load, when you run a motor aside from the inrush current ( well it's not really inrush but a higher current until the motor is spinning fast enough that the back EMF (Electro Motive Force) reduces the current) the load is inductive because of the motor coils, this means the current lags the voltage so that while instantaneously the current and voltage are out of phase the voltage must stay at ~230V but the current must not exceed the current rating of 22 amps. This means if the power factor of the motor is 0.8 you are only able to supply it with 4kW. These capacitor excited alternators are a weird black art to design but they are simple. This one seems to run at 3000RPM so it probably has a coil and diode in the rotor wound to give a north and south pole when it is energised. This then creates a magnetic flux which passes the main output coil. In this instance the output is only 100V open circuit so for some reason the magnetic flux hasn't saturated and I suspect the diode in the rotor or more likely there is a temperature limiting device, like a thermistor has failed in the rotor circuit. The rotor is energised by the exciter coil and capacitor, @the village idiot says he changed the capacitor and unless the rotor residual magnetism is sufficient to excite the output to 100V by itself this circuit is okay.
  21. The chart shows the current chance of dying is a bit over 1% at 70 but statistics from China show that the chances of dying at 70 if you get covid is 8% however the chances increase 1.5 times if you are male. UK predictions based on those dying in hospital are much better but hospitals are becoming inundated.
  22. Me too plus I'm not so sanguine about the BBC chart showing my personal chances of dying this year have increased from 1% to 10%
  23. It may be cheaper to get a new one but the engine will still be good. The difficulty in reusing these things is the alternator is built onto the motor and only has a bearing at the outer end making alternatives difficult to fit.
