antarmike Posted July 16, 2009 Share Posted July 16, 2009 Or a seriously carbonised engine. I wouldn't touch the Carbuterrtors until I knew the timing was spot on. Quote Link to comment Share on other sites More sharing options...
gritineye Posted July 16, 2009 Author Share Posted July 16, 2009 The big problem with these carburettors is that they have to be set out of sinc. The accelerator pumps are vacuum operated therefore after setting each carb to run right, it is then necessary to loosen the connecting link between them and adjust them so that the pumps work at exactly the same time, if this is not done back fires can not be avoided. The accelerometer pumps also come back into operation when flat out, to help the main jets flow enough fuel, this is also affected if the out of phase set up is not correct. This procedure is set out in the workshop manual but it has to be read very carefully to spot it, it has been a while since I've done it but it works. It's just a case of take your time, being methodical and following the book exactly. Of course the ignition system and tappet clearances also have to be spot on first.

rbrtcrowther Posted July 16, 2009 Share Posted July 16, 2009 Sure i've heard stories of engineers sitting on the front wing adjusting the carbs while the scammell is driving along:shake: Hard enough without the eyebrow and hair burning backfires! Sure theres somthing about not fiddeling with the carbs without the air boxes fitted due to the chance of hair loss:rofl: Quote Link to comment Share on other sites More sharing options...
gritineye Posted July 16, 2009 Author Share Posted July 16, 2009 (edited) It HAS to be done without the air box, I am living proof that singed hair can result from this procedure............... Edited July 16, 2009 by gritineye Quote Link to comment Share on other sites More sharing options...
big steve Posted July 16, 2009 Share Posted July 16, 2009 I set the timing to the manual its a new magneto cap etc it only does it when ticking over Quote Link to comment Share on other sites More sharing options...
gritineye Posted July 16, 2009 Author Share Posted July 16, 2009 I set the timing to the manual its a new magneto cap etc it only does it when ticking over The usual problem is back firing when first opening the throttle to accelerate, like a progression jet is blocked, if it opens up cleanly then you have a different problem, maybe idling too rich, faulty float levels or leaks in them? Floats have to weigh the same, they have the weight stamped on them in grams, IIRC. Quote Link to comment Share on other sites More sharing options...
gritineye Posted August 8, 2009 Author Share Posted August 8, 2009 As the headlamp guards on Forceful have been repaired loads of times now I decided to make a new Sumo pair, as per original pattern but slightly wider steel with thicker non bendy mounting plates. This gives more clearance behind for the lamps so should be better protection, but it's hard to spot the difference. Strangely a Scammell gear makes the perfect former for the radius....:idea: Just need a couple of bits of that tread strip stuff to finish them. Just proves the old saying, "It's a Fowl(er) wind that blows no good"....:-D Quote Link to comment Share on other sites More sharing options...

Jules Can do if you want Jules, used all the right size steel I had though, would also need your old ones as the mounting hole positions seem to be completely random, as you can see from the pic.

julezee001 Posted August 25, 2009 Share Posted August 25, 2009 Thought I'd add my troubles to this thread and hopefull repair. I didn't take part in the truck trials at W&P this year cos there were nasty noises from my friend Simons Explorer, PSY 974, whilst driving over the humps in the arena. Finally looked into it on Saturday with Thors blog in mind, and found a broken rear axle oil pump. Luckily the bearings have all survived, but unfortunately the largest spacing washer is badly worn, and the main pump housing is worn too allowing the huge thrust bearing to move back and forth wearing both further! Luckily I have the spare Explorer 01 BD 28 which has a largely complete rear axle, which on closer inspection has a great worm gear, and complete pump. With any luck all will be repaired in the next few days as we're off to Bethune with IMPS on thursday next week! Below are various pics of the work in progress. The socket I had to make to remove the rear worm nut was fun, and the nut is pictured beside a 27mm Landrover wheel nut! Jules Quote Link to comment Share on other sites More sharing options...
gritineye Posted August 25, 2009 Author Share Posted August 25, 2009 Lucky you caught that in time Jules, what do you reckon was the cause of the pumps demise, and what were the symptoms? Quote Link to comment Share on other sites More sharing options...
