    Saracen hill climbing

    On our M55 the electric pump we fitted aided start up, but restricted fuel flow when power was required. We switched back to the mechanical pump and the issue went away.

    Discussion on the bling ferret

    Whatever did become of that Ferret (aside being put up for sale at silly prices on multiple occasions)?

    Antar towing a rocket???

    Having watched the Honest John video, it seems a lot of work to fire 1 missile! I count 3 specialist trucks (albeit based on common mechanical components), a specialist trailer and then M151 and M35 vehicles for command/control and troop transport. Can't help thinking a medievil catapult and a dustbin full of flaming grease may have been easier...

    Our M55 in happier times. Interestingly I have seen a picture of one of these trucks with a matching trailer which has the same size load bed!

    Antar towing a rocket???

    Having driven an International Harvester M55 (with Continental 6602 Gasoline engine) on more occasions than I'd care to, they do sound like a heard of aircraft when driving through built up areas. I also noted that the exhaust is just at the right height for smoking out posers in soft top BMWs at traffic lights.... as for brakes and turning circle, the less said the better! Although specified for carrying Honest John resupply loads, our one never had the Honest John mounting frames installed. The firepower museum also had one that was fitted with the tie downs.

    Jaguar J60 carb diagram

    Resurrecting an old thread again, does anybody have details on setting the float height on a CVRT carb? I'm contemplating building up a good one using a rebuild kit and it would be good to be able to check that the float heights are correct. Doing this on my MUTT made a big difference to how it runs! And yes I still seem to be taking Spartans to bits as suggested further up the thread...getting there slowly!

    Mushrooms in deisel

    I work on the railway and we had a massive issue with biological growth in our fuel. We now have a rig which treats all incoming fuel deliveries (automatically) with a biocide. The issue became more prevalent when the sulphur content of fuel was reduced, as this kept the bio in check. Lets not forget that oil started out as organic material.

    Be aware that this issue will only get worse in future as the bio-fuel content in fuel increases.

    Which turret side bin do you have Terry? I have one (can't remember which side so will check), but still require the other.

    It's here! (Bedford RL)

    At work our drivers have taken to colouring in the LEDs they feel are too bright with felt pens...seems to do the trick though!

    Fuel problems

    It's possible that the pump flow is insufficient to keep up with the engine. We installed an electric pump on our M55 truck with a 9(ish) litre petrol engine (suffered evaporation and required priming if left for over a week) and it cured the fuel evaporation issues but wouldn't keep up with the fuelling requirements on the move. We switched back to the manual pump and she ran fine again.
  15. I would be vary weary of doing anything with wheels, with the typical attrition rate being 30 miles of driving between a tyre becoming de-bonded and coming off the rim (necessitating a wheel change). The wheel is then effectively scrap.

    WW1 Thornycroft restoration

    In the steam railway world we leave new cylinder castings out to weather for as long as possible before machining. At least two of our out-of-ticket locomotives (which won't be in the overhaul queue for a while) already have new blocks sitting outside. These should be well seasoned by the time they are required for machining. Lack of cylinder block seasoning was a problem in some locomotive classes when constructed from new, and they required much remedial work and ultimately new (seasoned) cylinder castings .

    cvrt endless track

    Pretty sure I remember seeing some plastic tracks on a trials/development CVRT that was in Withams some years ago, but as for any further information I haven't seen any. Vince

    what do you use to cover your vehicle ?

    I looked at getting a replacement cover, but it was about a 3-4 month lead time and almost 65-70% the cost of a new complete shelter. Now our 2 covers have given out completely, the frames would have to be dismantled to fit new covers now so the vehicles have just gone back to being sheeted up. We also put storm straps over the top (proved invaluable!) but these caused the sheet to wear through in a couple of places.

    Got about 5 years out of our Machine Mart tent before the covers disintegrated.

    WW1 Thornycroft restoration

    Pyramid nosing (which I didn't know the name of) is used extensively on ex London Transport busses (think RT, RF vintage).

    CVRT Coolant?

    We had the issue of coolant hoses leaking in the cold on a fleet of new diesel trains in 2004. We had to change the type of clamp and the applied torque was critical. I have a friend with a vintage bus who had the same issue, and up-rating the hoses for silicone and more modern clamps (in place of jubilee clips) have cured his issues.

    Steve, I would offer to buy it back at what you paid me for it, but I think you'd tell me where to go...

    Oil on steering and main brake rotors

    Our Spartan issue came to a head following loading onto a transporter truck. The steering was fine when I loaded up, then she got rained on and when I unloaded (I think there was a period of storage between these events), the steering was gone! I assume the water level in the gearbox compartment caused the steering brakes to become contaminated due to the angles the vehicle achieved on the loading ramps. That and being the oil/water being thrown around by the rotating cooling fan and brake disks. Anyway that led to the eventual discovery of the final drive being the issue.

    Oil on steering and main brake rotors

    Could be the seal in the final drive output (quill) shaft. I've had that on a Sultan we once had and we removed the final drive to renew the seal. Although heavy, it's not too bad a job to do. We walked the final drive out on to some timber packing, pulled the shaft, old seal off, then refitted it all. Including breaking the track, about 3 hours work. We also had a leak on our Spartan final drive, and this turned out to be the ring of bolts around the outside (which should have been lock wired) were all loose! I'd suggest a good clean up and then try and identify where the leaks are originating from.
