    1 inch seamless steel tube

    Got a bit from Metal Supermarket just right for the job. Only problem the postage was as much as the tube, but I have got the bit I need though. Very quick too.

    More of an update fuel pump issues, diaphragm is ok one of the valves in the pump stuck open due to the rubber seal disc has swollen a bit and jamming on cage which retains the spring, trimmed the disc down a bit reassembled and all good.

    3.5 CCk Onan generator

    Thanks guys for the input. I think I have sorted out the bad starting, discovered that of the 4 brushes on the starter side one of the brush connections to the case of the generator was very loose looks like its been like it for years, probably why I have always had problems starting it. So having cleaned and copper slipped it and tightened up good and tight, it seems to start fine but I can't get the fuel pump to prime so engine keeps petering out, then won't start till you tip a bit of fuel down the carb then it runs for a few seconds. Suspect I will need a fuel pump diaphragm, will look tomorrow.

    3.5 CCk Onan generator

    ok it seems to be marked "12volts Bat" but on a good truck battery it refuses to turn over in one continuous motion and the rotation is very slow !!! Any suggestions on how and what to test if a winding is down, or any other thoughts ?

    3.5 CCk Onan generator

    Hi all, I have a 3.5 Kw military CCK Onan generator and have heard it might be 24v for starting, as it has never been good on only 12 v you have to pulse the start button to rock the engine past compression the it will turn over and start. Suggestions please ?

    Types Of GMC Workshop Bodies

    Howard, do you have any pics of the structure / framework of these sorts of bodies between the inner and outer skins ? Also does anyone know what these bodies weigh ? Cheers
  10. Hi, I have never had this problem with my GMC, but I think there has been past conversations about this issue. From what I can remember you need to make sure there is enough free play on the adjusting rod to the master cylinder, if not the piston in it can cover the fluid return hole back to the reservoir in the master cylinder. This then applies pressure in the hydrovac and when engine started it thinks you are pressing the pedal and so as vacuum rises jams brakes on.

    Types Of GMC Workshop Bodies

    Ah ok, so does anyone have any pics of the construction of how they are put together mainly the construction of the side walls ?
  12. Hi all, got some questions to do with GMC workshop bodies, I have noticed there seems to be two types. One has six windows on each side, the two rear doors are different sizes and has a straight edge to the bottom sides from front to back above the twin rear wheels. The other only has three windows each side, the two rear doors are the same size, a more curved roof, a recess for the twin rear wheels. What is the intended use of both and as they are both the same size why two different body types ?
  13. Hi looks very much like a GMC 2 1/2 ton split axle transfer box.

    What type of TIG to buy

    Cheers all for the advise, the thing which concerns me with the inverter units is that the welder will not be used often and I have heard inverters dont like sitting round in cold dampish workshops for months on end where the transformer ones are more robust and have lots less electronics in them, oh well we shall have to see. Never TIGed before so whats with all the different filler rods ect and what are the opinions of type of gas to material !!!!

    What type of TIG to buy

    Hi all, thanks for the input. Have found a company which is British and stock parts for their welders for 20 years.... Was considering one of these beasties, bit ugly but I am not going to be looking at it. http://technicalarc.co.uk/index.php/tecarc-tig/ac-dc-tigs?page=shop.product_details&flypage=flypage.tpl&product_id=20&category_id=18 Not overly sure about the reliability of inverter unit, like the old school ruggidness. Thoughts please
