Thanks Joseph. I should have included you Joseph as well as your Dad and Chris! Hey Joseph, when's your Dad going to get his own Large Frame as I know you got two yourself

I have listed a crawler on E Bay, it is a petrol MG40 with full hydraulics and pto, serial number 15343 so is one of the very last produced in 1965. It runs well but tracks need rebuilding, included with the sale is a full set of new rubbers bolts and track washers. Mag and carb have both been rebuilt.

I think it's a 1hp Nigel, same as the O&R engine

Just caught up with your progress and challenges Darren. A real 'Labour of Love' and very well executed work!. It's a shame you couldn't obtain the original tyre size and a rough estimate is an extra 9" of machine travel for each rpm, or 24% increase in speed, so your attachments/speeds will be less effective and you may have to break into a 'Canter' behind it . As for the Shaft wear, with the need to fix it one way or the other, I would look to replace the shafts. Not knowing the lengths of each one, or what the metal 'Hardness' figure is, it would not be as difficult or more labour intensive to grind off the Sprocket welds, mark up and re-weld onto new shaft(s) after milling the Keyways and pin locations. Treating to the original RC Hardness may not be required if precision ground Silver Steel is used, as it is around 27 RC hardness in it's supplied, machining condition. A 13" length of 1" dia (+/- 0.0005") is £12.27+ vat....... longer lengths avail. Correct Bushes can then be purchased........ I'm not an expert though!. I'm sure Jim Beacon will provide you with good/better advice and looking forward to seeing your progress. Glad to see the the Mk12 from John/Alan has found a very useful home.

Great find Andrew, I'm excited too

This is awesome guys , I'm so looking forward to seeing the end result & I'm delighted with this restoration thread , I never though it would get to have a dedicated thread on its revival .

A few photo's of the hood, fenders etc after they were painted Monday.. They be looking good

Have also stripped all the old paint off the gearbox and found the brass I.D tag under all the paint......... M4694! I have no idea how many were made and exactly how old this one is??? The engine, if it's original, has a brass flywheel.......... I couldn't see any numbers on it, but then I didn't look too hard?
