    CVRT break downs

    in Tracked vehicles

    Posted

    Diesel fan belt failure.

    Had the live feed wire come loose from the ballast resistor in the ignition junction box in my Sabre, resulting in no spark - took a while to track that one down.

    Variety of fuel supply problems in Spartans due to dirt and water in fuel tanks.

    Shed a few road wheel rubbers but never to the point where it’s stopped the job.

    Couple of steering mc failures but usually after standing for a long time..

    Did have one complete engine failure which I never figured out what it was - but at the time I had a load of spare engines so it was easier just to put a new one in (those were the days!)

    Fuel supply is the only thing that’s ever stopped me mid journey…on one occasion for about 20 mins in the middle of a busy crossroads until I could nurse it out of the way!

    I don’t tend to go very far on the road - maybe 7 or 8 miles to a country pub, but I always try to have at least a rough plan in case things go wrong - even if it’s just a local breakdown number..

     

     

     

    CVR(T) D Spartan Fan Belt Replacement

    in Tracked vehicles

    Posted

    As Chris says a bit involved but not especially technical.  Just keep taking bits off until you can get to where you need to be.

    A couple of other points - the diesel fan belt does NOT need to run particularly tight - 14mm free play at the mid point, and you shouldn’t have to work too hard to get to this.

    Some people suggest adding a spare fan belt while you are there and cable tying it out of the way.  Then if this belt fails you have one ready to go.  I’ve never done this and there are other people who strongly advise against it and say it is almost certain to cause belt failure (presumably through the spare interfering with the running belt).

    Since the question is about the best tracked vehicle, rather than the best tank, I feel I can safely and justifiably say CVRT of course!

     

    Coming up to 50 years in service, and highly likely to make it to 60 years. Think about it - that would be like using a Sherman in 2003!

    Clearchannel show- Battlefiled recovery

    in Archaeology - WW1 to the end of the cold war

    Posted

    Watched the 4 episodes of this on Netlfix, set in Latvia , 4 amateurs excavate German and Soviet battlefield sites from the front that eventually resulted in the Kurland pocket. It's not really archeology in the true sense of the word, However

     

    I learned a lot about that part of the war I didn't know, especially in episode 4, ( and maybe a lot of people didn't know ) About the killing of German settlers in reprisal attacks. however, this scathing article and it's criticisms are also true.

    Anyone else see this, what do you think or feel about the show?

     

    I watched this a few months back, and felt a bit uneasy about it but found it interesting all the same. In retrospect though I think that article is spot on! Hopefully we wont see another series...

    Tips for driving a CVRT on sand...

    Make turns like a 50p with regular stabs on the steering is what I've been told by a friend who shed a track at an agricultural show. He was driving on loose dirt (the advice was given retrospectively to him!)

    A certain Mr Moss I seem to remember - funny how the advice always comes AFTER the event - if I remember rightly someone else asked 'is it supposed to do that'!!!!

    Thanks Andy very helpful

     

    I think my plan will be to remove the wheels. The centre right wheel station has a very pronounced bend in the ball joint, which must have happened a long time ago as the wheels are all straight - I suspect it was the result of being fork-lifted pre restoration. I do have some spare NOS wheel stations so I will try and get a spare off them. Anyway the upshot is that the ball joint is hard up against the cylinder on that side so it has to come off anyway...

     

    Always something to do!

     

    Cheers

    Having got fed up with running what is effectively a total loss braking system (ie pour in large quantities of expensive ISO10 which promptly pours out!)....I have decided to have a go at changing the cylinder seals. Got new seals (not NOS) from Richard Banister, and was expecting this to be fairly straightforward.

     

    But....for most of the cylinders they seem to be fouled either by the handbrake cables, or steering gear. The brake cables won't come off without removing a roadwheel. Am I missing an easy way of doing this?

     

    Also, was thinking about trying to get some seals made in polyurethane, which seems to be recommended for this type of application, but the new seals are quite a shiny, plasticky material so I suspect may already made of this. Andy J if you're out there I think you were going to try a different material - any success?

     

    Cheers

    Alvis Reunion with photos.

    in MV Chatter

    Posted

    I was at school around the corner from the Alvis during the early 80's. While I don't consciously remember seeing CVRTs coming out of the factory gates I do wonder if subconsciously something was planted back then. I was also fortunate enough to pick some spares up from Martin O'Neill (something of a legend in his own lunchtime at the Alvis) at the old Baginton test site a few months back. When the site was sold he managed to persuade the powers that be to let him keep hold of one of the old sheds to house his own vehicles. Turns out it was the old winch test shed where Samsons, stollies etc were connected to a big static testing rig. Some really fascinating stories. At Baginton most of the old buildings, including the aero engine test beds, are still very much in existence. The old test track is also still there, but now private property and not accessible, so can't take the Sally for a run round unfortunately!

     

    Attached pics are from a previous article in the Evening Telegraph. It is good fun trying to spot what the parts are in the bins in the machine shop pic! First two are Holyhead Road, last two are Baginton...

    Non Starting CVRT

    Agree with all the above but also check the connections in the ignition junction box where the ballast resistor lives. I had one which had worked loose and was only making intermittent contact. Now that was a pig to find!

    Best War Film Ever

    Posted

    They were not divided. About a guards armoured regiment going through Normandy and Belgium. Made in 1950, lots of Shermans and many of the actors had served. A great and very authentic insight with none of the cheese seen in modern films. Highly recommended.

    CVRT Sabre engine change

    Thanks Robin. Cant believe its been nearly 3 years since I did this job. Agree completely re the engine leveller (thanks Toolman!), even more so if you don't remove the alternator, although having learnt how to do it, I would probably take it out every time now.

     

    I am struck looking at the photos by what a complete dump our old workshop was - given that it was midwinter and the job was done over a few weeks weekends and evenings I must have been feeling really dedicated! Our new place is much nicer, I just never seem to have the time to get there!
