  1. Mike, I came to the same conclusions as you did by very much the same thought process, and was expecting the off road performance to suffer, and resisted a Diesel conversion for many years for that reason .

     

    In some ways it has, gone is the ability to trickle along at 300 rpm and then power up a very steep hill all the way to 2400 rpm if needed, then lift off at the top and drop down to 300 rpm for the decent on the other side.

     

    Tick-over is around 700 rpm when hot now and I need to go up a gear to avoid wheel-spin when the power comes in, which means I have to change down a gear at the top for the decent, which is not so controlled now.

     

    I have recently improved the throttle control by moving the rod linkages in relation to the pivots of the bell cranks, (drilled new holes) this has "geared down" the pedal so any bouncing around produces less unwanted input.

     

    All this is may seem rather extreme for many people reading this, many owners may never attempt such things, and therefore miss the point of our concerns, but the main attraction of Scammell Explorers, WLFs and such, is often the fun to be had off road with them.

     

    As you say it's nice to see other people's opinions

  2. I have been watching this thread but reluctant to post, however I would not want to see you go to all the trouble of fitting the Cummins only to find it unsuitable. In my experience Cummins are all top end power and gutless at low revs thereby making them unsuitable for your purposes, perhaps you would be better off doing a swop for an engine with more low down grunt.

     

    I tend to agree with this as the Cummins L10 in my Explorer is flat and gutless below 1200rpm, fine above that and cruising at 15-1800 rpm, which seems to suit an overall top gear (engine to rear wheels) ratio of 8.35 to 1, if your gearing is much higher than this you will be 'rowing it along' with the gearstick. It suits an Explorer fine though.

  3. This is one of the most fascinating MVs I have come across, talk about think outside the box! No doubt someone will come up with more info and a couple of pictures of it when finished, seen and snapped at Beltring 2007.

  4. Yes that Kraz is a beast, need to take a better picture as you don't get a feel of its size. Jim bought it to tow his Russian BMP but he's got quite a few projects to do.

     

    He also has this mongrel, a Zil 131 with a Bedford body, mounted with a Bofors gun & just room for his German bike & sidecar. And probably a bent barrel!

     

    See here for size comparison

    East meets west in the strangest places!

  5. two spare tyres which I rolled out the back with great gusto! Then I figured that I needed to get them back to the shed... Figured I'd lift them up with the jib... half an hour of winding later I decided the forklift would be a better option! :argh:

     

    I meant something HEAVY :sweat:

     

    can't help with gauges, but shouldn't be hard to find.

  6. All good stuff and progressing with commendable vigour, looks a whole lot better already :thumbsup:

     

    The gearbox should read about 15 psi cold, but the important bit is 3-5 psi when hot, at road speed, the poor old gauge needs to be accurate to read this, so as long as there's any pressure at all it should be OK

     

    You'll be glad the jib winch is slow when you try to lift summat :-D
