  1. Hi Chris, that is the best looking J60 engine i have seen.Note the Kigas jets fitted to Inlet manifold.Lots of these engines fitted with Kigas jets all haveCon rods through the block,i suppose driver running engine in dragster mode.Do you have any instructions on replacing a J60 Head Gasket set.Thanks :-D

    Why would the Kigas system cause connecting rods to damage the block? I thought Kigas system was used to help start the engine when it is cold.

  2. It has taken a bit of time, working around the bad weather, but the spare wheel carrier is finally in place and functioning well.

     

     

     

    Watched the video, absolutely astounded at the engineering elegance. Wow! I have an m923a2 (US made 5 ton cargo truck, Gulf War vintage) with a spare tire behind the cab, but I would probably prefer sitting in a dentist chair for an hour rather than attempt to hoist that thing down. British ingenuity, for sure.

  3. Alvis must have found a easy way fitting wheel stations at the factory..

    One day someone may tell or show us.

    I think it was called an army maintenance depot, with mechanics and grunts by the dozen, all available at no charge to fix whatever calamity arose. No charge that is, except the truck full of cash expended by the treasury and borne by the common man. In private ownership, alas, this arrangement doesn't work!

  4. Now theres ya problem.. Broken tracta joint

    Was this engineered to fail in order to protect other internals in the driveline or wheel hub, which presumably are more expensive and difficult to make?

  5. Hi Simon,

     

    OM13 is equivalent to ISO10. Comma LIC10 is an ISO grade of 32 which is the common hydraulic grade for plant equipment, etc. The higher the number the thicker the viscosity. The difference in grades is done for a reason, otherwise the military would have standardised with the 32 grade, which was also widely used in their plant. Best to keep with the specified grade, then if any problems occur, you know they are not related to the incorrect fluid.

     

    I was told OM13 is equivalent to ISO 15, so seeing ISO 10 in this post is troublesome, because both sources for the information know what they are talking about. I need to get hydraulic fluid and now don't know which spec to order. :cry:

  6. Looks a bit like the Tilt Trailers we used to use behind Aveling Barford Tippers.

    Often had Muirhill A5000's or 100B Crawler loaders on board.

    I'm no expert on trailers, but this doesn't look like a tilt trailer, because the front seems welded to the frame. It has to be a US trailer, though, since importing one would be a colossal expense. I'm just wondering where I can find one like it:-)

  7. Greetings,

    Here are two more pictures. There is a 5ton (72' M813A1) that will be taking over this year's towing duties. JimK

    Jim, what is the trailer you are using, is it civvy? I am looking for something to tow my Saracen with my 5 ton and most of the trailers being sold aren't low enough (5 ton tag along trailers have decks that are over 3 feet high). I was thinking of buying a civvy trailer, but not sure how the brakes and 24V and trailer plug would all work out with military setup.

  8. I recently received the cards from Bovington for my Saracen 82BA77, but they list no chassis number. The numbers on my escape hatches are "404".

     

    What's weird is that cards list it as MK2, but mine has RFC and would seem to be an MK6. Wouldn't the cards reflect the changeover when vehicle was uparmored?

     

    Also strange is the fact that date in service is listed as July 5, 1955, but first activity is from August 22, 1967. Does this mean it just sat for first 12 years of its life? Or perhaps there is a missing card? The latter option seems less probable, since there are 2 cards already, so if one was missing, there would have been 3 cards?

  9. Below is the pick handle, with three coats of paint/glue, and rubbed down between each one, with a final rub down to dull off and slightly distress the finish. I'm very pleased with the finished result as it was a bit of an unknown using the paint/glue mix.

    The last picture shows all the tools in the back garden, baking in the afternoon Sun. The bright sunlight makes the woodwork look a bit more pale than it actually is. Next time I have the truck home, I think the tool rack also needs a clean and paint.

    Awesome, just awesome. Can you give detail on the electrolysis process? What was in the bucket? How much voltage/amps did you apply to the solution? I might need to do this at some point.

  10. There is some coverage on the Jolley module on B Series towards the end of this:

    Clive, I read your report now several times, must admit most of it is way over my head, but I am convinced the electronic ignition module upgrade you discuss at the end is a no brainer. I contacted Jolly, but they are on vacation until July 13. I will order the module from them and have it installed. Thanks again for your link to your report.

  11. yes Montie!, ...twas I, but now and then the old thing does have a 'hissy-fit', and requires a more delicate touch and some 'magic engine starter spray'............ + batteries have to be very good condition too.....

    Matt, I know this is from ages ago, but are you still having starting issues? I am going to fit electronic ignition to mine, there is apparently someone in UK (Jolly Engineering or something like that) that sells direct install kits for B80 RR engine. This is supposed to make them start easier, or so I hope. They quoted cost of kit at 205 GBP. What do you think about that -- worthwhile expense?

  12. The MK 6 Saracen was a MK 3 that had extra armour added and a few other upgrades, itself a MK 2 with reverse flow cooling. Externally, the most telling are that the MK 6 does not have a rear gun ring or roof window, Has a round flange around the base of the turret, has a squared cover over the fuel filter and has heavy armour plates welded to the sides. Internally, the MK 6 is fitted with brown spall liners.

     

    Cheers,

    Terry

    Terry, maybe a dumb question, but I hope you can educate me. Was the MK6 applied as a new designation for an existing vehicle (so they took MK3, uparmored it and it became MK6) or was it new construction - a new vehicle built from scratch? If it was uparmoring an existing vehicle, do you know whether the donor MK3 would have also been overhauled at the time? In other words, would they take the MK3, tear it apart to renew everything and then uparmor the hull? My MK6 (which I still haven't laid eyes on) is missing its data plate, so I am trying to figure out whether it saw a full REME overhaul in its service life.

  13. A couple that spring to mind are,

    A straight bar is for emergency towing only. Not to be used for pushing or recovery of unbraked loads. As Grasshopper says Hollybone A-frame'a are worth their weight in gold.

     

    :shake:

    Why is straight bar unsuitable for towing? And why is A frame better -- it spreads forces across two points or is there another reason?
