big chris Posted April 12, 2009 Share Posted April 12, 2009 The reason i asked this was due to the fact that when my scammell arrived at my home it ran perrrrfect after i kind of got it fit for a test run on the main roads i never even made it out of my town before the i lost all power and the engine seized solid and i do mean solid it had enough oil and water when i set off and when it died when i lifted out the engine and looked inside it looked like i could have eaten my mash from the inside of the engine there was not any signs of black diesel oil anywhere you literally could have eaten your dinner off any part of the inside anyway i also heard of a bloke that ran his matador on a modern engine oil and it basically cleaned the engine so much in 12 months the bottom end blew out of it the advice he was given was that these engines kind of liked to be gummed up inside and could not stand having all the carbon build up removed now my new engines in i want avoid the same engine has good oil pressure throughout temp but i found it hard to get a replacement engine (lake district to bournemouth in a night was a good drive) which is why i asked cheers chris Quote Link to comment Share on other sites More sharing options...
younggun Posted April 12, 2009 Share Posted April 12, 2009 (edited) these two engines are both running on modern oils 15w40 from memory and both seem to run fine on it as is my scammell . Edited April 12, 2009 by younggun Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted April 12, 2009 Share Posted April 12, 2009 the engine seized solid and i do mean solid it had enough oil and water when i set off and when it died when i lifted out the engine and looked inside it looked like i could have eaten my mash from the inside of the engine there was not any signs of black diesel oil anywhere you literally could have eaten your dinner off any part of the inside anywayi also heard of a bloke that ran his matador on a modern engine oil and it basically cleaned the engine so much in 12 months the bottom end blew out of it engine has good oil pressure throughout temp but i found it hard to get a replacement engine (lake district to bournemouth in a night was a good drive) which is why i asked cheers chris Chris, I understand your concern, with very old engines that have an unknown history and the possibility of having been run on non-detergent oil, it is better to err on the safe side and only use a Straight non-detergent oil, until the time comes for an engine overhaul, when it will be internally cleaned. As you said it was a Leyland 690 ( I know the AEC 690, assume it is the same?), that dates from the 1960's so would assume it to have been run on modern detergent diesel oil.......but who knows? A good way of telling, would be to drop the sump and if thick with sludge in the bottom, that would indicate having had a straight oil in it. In fact I would drop the sump if only to look for any signs of bearing metal and to check the bearings ( remove caps for a visual ).......at least it will give you peace of mind.

rbrtcrowther Posted April 13, 2009 Share Posted April 13, 2009 Hi chaps, Don't suppose anyone has a couple of new oil filter elements for a meadows engined scammell lying around? Are you still abe to by new ones or is there a pile of old stock somewhere? I have cleaned mine up but even the airline fails to penertrate through to the center. A new oil filter should not drop oil pressure more than 3psi so god nows how many psi my old ones are dropping. Could really do with some pronto if poss. I will use mine if i have to but would rather try new ones if possible. Hope you can help Rob. Quote Link to comment Share on other sites More sharing options...
N.O.S. Posted April 13, 2009 Share Posted April 13, 2009 Could really do with some pronto if poss. I will use mine if i have to but would rather try new ones if possible. Hope you can help Rob. I would get some new ones. Most old sizes are still available from one or other source. Hopefully someone will give you the filter number. If not (and if I remember, and if I can find it) I can bring home on Wednesday an oldish Crossland catalogue which has a useful cross reference using dimensions and a photo recognition chart. You'll need to measure the length, o.d. and i.d., and preferably post a photo of one for the centre detail. Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted April 13, 2009 Share Posted April 13, 2009 Rob, Am I right in thinking your engine is a 6DC630 ? Looking at the 1970 AC Filters list and oil filter is AC81, same type used also in AEC inc. AV505, Austin petrol lorry, Leyland, International BTD8 crawler, etc. Dimension Outside diameter ; 3.81" Length : 6.99" Internal diam. ; 1.95" I would double check these dimensions with your filter just in case it is not standard.

rbrtcrowther Posted April 13, 2009 Share Posted April 13, 2009 Will measure filters tomorrow. They are blooming tall possbly 12" Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted April 13, 2009 Share Posted April 13, 2009 Will measure filters tomorrow. They are blooming tall possbly 12" Rob, Best bet is to remove it and measure, photo will help, to ensure it is the correct pattern. That was the number listed for that model of Meadows engine. Nothing is that simple! Quote Link to comment Share on other sites More sharing options...
rbrtcrowther Posted April 14, 2009 Share Posted April 14, 2009 Well i have measured the filters. They are...10 1/2" or 270mm tall (but they are a bit squashed by the sealing plates so it think they should be 11" tall) 4" in diameter or 100mm and the inside is 2" or 50mm there is a removable spring inside them to stop the filter crushing with the oil pressure. I have found some part numbers on the filter casings / Tecalemit oil filter no. EA 2042. Element no. FG 2351 / 101 I have has no joy searching the internet as yet. i may have to resort to steam cleaning them at work! Quote Link to comment Share on other sites More sharing options...
gritineye Posted April 14, 2009 Author Share Posted April 14, 2009 (edited) These occasionally turn up at Beltring, appear to be the same as on petrol meadows. Not much help I'm afraid but they may not be as rare as you think. Worth ringing Banisters with numbers as he is very good at cross referencing military parts, and very helpful: http://www.milweb.net/go/banister/ Edited April 14, 2009 by gritineye Quote Link to comment Share on other sites More sharing options...

N.O.S. Posted April 15, 2009 Share Posted April 15, 2009 Had a look through some old filter catalogues today - found a number match to Crossland 113, which unfortunately is no longer available. But it might be easier to find N.O.S. Crossland than the Tecalemit! Quote Link to comment Share on other sites More sharing options...

croc Posted April 16, 2009 Share Posted April 16, 2009 Hi can anyone tell me the best oil to put into a leyland 690 turbo engine as ive been told to use straight 30 oil but i have also been told to use a modern turbo diesel oil and i dont want to just use a fleet 15/40 diesel oil as i believe this has detergent in it which will wash the engine internally thank chris page from manual covering 600/680/690 engines Quote Link to comment Share on other sites More sharing options...
big chris Posted April 19, 2009 Share Posted April 19, 2009 hi been out in the explorer today seemed to get a bit warm after a while does anyone have any pictures or advice on the fans they have used with the leyland engines my fan is a good bit away from rad and i have no cowl for the fan but im thinkin of modifying the fan closer to the rad and ading a cowl but the leyland engine fan seems a lot lower than the meadows which is sitting just above the front cross member so a big fan wont work ??? thanks chris Quote Link to comment Share on other sites More sharing options...
rbrtcrowther Posted April 20, 2009 Share Posted April 20, 2009 Got the same problem on mine (meadows diesel ) was thinking of fitting the petrol water pump but had issues with pulleys and compressor drives so will make a cowel to meet the fan.

gritineye Posted April 20, 2009 Author Share Posted April 20, 2009 hi been out in the explorer today seemed to get a bit warm Not trying to tell you how to suck eggs, but are you going by the temp gauge, or is it just steam coming out of the rad filler or vacuum release valve? If so taking these apart and carefully reassembling did wonders for mine, it now holds pressure which raises the boiling point. Quote Link to comment Share on other sites More sharing options...
big chris Posted April 21, 2009 Share Posted April 21, 2009 Thought about that bernard but i also got leaks from the rad under pressure so started thinking about mods to the fan to stop the leaks they actually stopped when it cooled slightly there was a little mist coming from the rad filler cap and header seemed very hot i have just bought a trailer to tow as well so i want rid of any cooling problems now cheers chris Quote Link to comment Share on other sites More sharing options...
rbrtcrowther Posted April 21, 2009 Share Posted April 21, 2009 Was the bottom hose hot too? Could be lack of draft from cooling fan. Poor water pump. Stuck thermostat. Clogged rad . Is the head gasket ok? no bubbels to be seen in the header tank when its running i hope!! I know of a scammell explorer with a leyland 680 in and the fan is nowhere near the rad. he tows a 30 odd foot living van. He says it getsd warm on the big hills but has never had to stop and cool off. Scammel is called jumbo. It's a big radiator with a 30mph wind blowing through it would of thought the only time it would get hot would be off road . Hope you get it sorted. Good luck.

big chris Posted April 21, 2009 Share Posted April 21, 2009 i think it could be lack of draft as fan is blowing not sucking and with no cowl and fan miles away from rad doing some mods to fan /waterpump to sort Quote Link to comment Share on other sites More sharing options...
julezee001 Posted April 21, 2009 Share Posted April 21, 2009 Both our Explorers run RR Eagle 220 diesels these days and the one with the engine/fan set further back has done lots of towing of all sorts, slow and flat out and has never shown any sign of over heating. A friend still has the Meadows petrol fitted, which always seems to run hotter, making the cab feel like a sauna on a warm day compared to the diesels. Despite this it doesn't seem to overheat? I don't think I can suggest a solution in addition to any already mentioned except that the radiator seems to be over sized for the original engine to allow for use in hot climates possibly, which would suggest some other problem? Good luck! Jules Quote Link to comment Share on other sites More sharing options...
rbrtcrowther Posted April 21, 2009 Share Posted April 21, 2009 Hate to say it but it sounds like you may be pressuring the cooling system somewhere:cry:. How long before it gets hot? Do the radiator pipes pump up hard very quickley when you start from cold? Keep us posted. Rob. Quote Link to comment Share on other sites More sharing options...
kevin royan Posted April 22, 2009 Share Posted April 22, 2009 My explorer is fitted with a gardner 180,i have no coweling on the rad but it only runs hot if the engine side covers are not fitted. Quote Link to comment Share on other sites More sharing options...
big chris Posted May 3, 2009 Share Posted May 3, 2009 fan works perfect now it really would wip your wig off if passing the front cooling perfect also anyone going to the scammell spectacular this week end? Quote Link to comment Share on other sites More sharing options...
