  1. I believe the GMC has a reduction ratio in high box and well as low box........so not really a overdrive effect so to speak.

     

    Yep did know that but its only slight, My interest was regarding the larger modern trucks, I assume the large diesels are fairly low reving so how do they achieve the high speeds must be a low ratio diff ?

  2. If you are going to change any of the rear 8 tyres beware that it is important to have the circumference's of them as near to the others as possible otherwise you get transfer box wind up and it puts undue strain on the drive train components and will wear the other tyres more, this is due to the two rear axles being locked together via the transfer box. This is the situation I am in and its looking like there will be 8 new tyres in the not to distant future :shocked:

  3. I've just taken the number off the chassis:

     

    CCKW-353362152R2

     

    Many thanks!

     

    CCKW-353 indicates type of truck and 353 indicates Long Wheelbase (164")

     

    362152 vehicle chassis number

     

    A2 not R2 indicates Banjo axles, cargo body, no winch.

  4. This is a photograph showing DS&O Rural Electric Cooperative's employees standing by a truck at the warehouse in Solomon, Kansas. The people in the photograph are (left to right) Roy Duck, Jake Elmore, Walt Moyer, Marv Eisenhauer, and Andy Anderson. DS&O Electric Cooperative was established during the Great Depression as part of the federal recovery effort to bring the advantages and economic stimulus of electric power to rural Kansas. In 1991, Smoky Valley Electric Cooperative in Lindsborg, Kansas, merged with DS&O, adding to the Cooperative's coverage area and member base. DS&O Rural Electrical Cooperative's office is located in Solomon, Kansas. It was named DS&O because members were from Dickinson, Saline, and Ottawa counties.

    Date: July 1947

     

     

     

    Not entirely sure this pic is a GMC as I don't think there are two rear axles ? recon it could be a 1 1/2 ton Chevy possibly a pole setter given the industry ?

  5. Original engine fitment were 3 American Packard engines producing 3600 HP giving a top speed of 50 MPH and carrying 10 tons of aviation fuel !!!!!!!!

     

    Surly you could fit 3 new engines for less than £100,000

  6. As far as I know there has not been any major steps forward in battery technology to compare with the tried and tested flooded lead acid batteries, they will stand much more abuse from over discharging and over charging within reason and still recover to last ages, I have heard stories of spiral gel batteries if over discharged don't recover well and are fussy regarding the charging voltages also they are expensive.

  7. Fifth wheel trailers do need to have Type approval, however it isn't law for a fifth wheel caravan until next October (2014).

    So once type approval comes in will that only apply to caravans built after that time or will it be retrospective.

     

    Some of these Fifth wheel caravans especially the larger US ones have an unladen weight approaching 3500 kg, when you add in the laden weight of additional furniture , crockery, your bikes and the barbecue the weight often climbs above 3500kg making them CAT 03 trailers which then mean they are subject to the same testing and plating required by HGVs.

     

    Thinking about this point as all caravans are over 1020Kgs unladen don't they require plating ? I presume there is a clause for them so is it if they are over 3500Kgs ?

  8. Thanks you very much, this is just what I was hoping to hear. So good to know VOSA have it right.

     

    Very well put for a complicated question.

     

    Could you just clear the last bit, that provided you have suitable mirrors it does not matter what sort of vehicle you have you can still tow a trailer or caravan which has a 2.55 max width ? (ignoring of coarse the weight issues)

  9. What Croc has said is correct, and equally it is complicated. The usual starting point is to determine what licence you have for towing. If you held a normal Cat B (with B+E) licence before 01/01/97 you are pretty much OK for most things.

     

    This is of interest to me and several friends, old license ie before they changed so we have B+E, C1+E with code 107 (so limited to gross train weight of 8250Kgs) and D1+E as I have heard lots of stories about what you can and cant do, so I was hoping to try and clarify as much as possible with regards to our situations, ie: general towing over 750Kgs.

     

    Next if the towing vehicle has more than 8 seats you need to check if you require any additional licence categories. For Unbraked trailers IE below 750kg Max Mass the max weight of the trailer cant exceed more than 50% of the Mass in running order of the tow vehicle. If the trailer is braked it cannot exceed the mass in running order of the Towvehicle In any case it cannot exceed the towing limit set by the manufacturer of the Towing vehicle. The Tow vehicle also has a maximum allowable Gross train weight (GTW), this is set by the manufacturer of the tow vehicle, but in any case for a licence before 97 it is limited to 8250kg, it is a lot less for later licences.

     

    This I can see, all ok there.

     

    It wouldn't be possible to make a true determination without knowing what your proposed combination consisted of. Incidentally the documentation always refers to the max permitted weight of the trailer, and people have been prosecuted for exceeding the combination of these weights even though the actual weight was no where near.

     

    I have a VOSA document that clearly states its the actual weight not the possible weights that is important.

     

    Now we are getting a bit juicy !!!! so what you are saying here then is all the licensing categories ect refer to max weights,

     

    but in reality, say you had a car which weighed 1200Kgs (guessing the average tow car) and was able to tow a train weight of 2000Kgs (this would be load and weight of trailer) but the trailer was designed to have a train weight of 3000Kgs (this would be load and weight of trailer) but you only had a train weight of 1000Kgs (this would be load and weight of trailer)

     

    So in this situation you have 1200Kgs car plus a train weight of 1000Kgs making GTW of 2200Kgs

     

    and not 1200Kgs car plus train weight of 3000Kgs making GTW of 4200Kgs

     

    Would this be legal or not :nut:

     

    Also with reference to trailer widths this I gather is now 2.55 regardless of what is towing it obviously you need wing mirrors to be able to see down the sides though.

  10. Don't understand this, why does the trailer only have to be 750Kgs ! Is it not the total train weight which would be 8250Kgs so if the towing vehicle is lighter then the trailer can be heavier bearing in mind I am on about 5th wheels.

     

    Remember that the 8250kg limit is only if you have a 750kg trailer. If the trailer is heavier then you can only go to 7500kg.
