the DT guy Posted June 4, 2022 Share Posted June 4, 2022 The Rogers has come on leaps and bounds since the last post, rear crossmember is know welded in and the long endless task of welding all the little bits back on begins. removing the ramp hinge mounts from the old rear crossmember, simple tidy up with a cutting torch and grinder. Then set up with a calibrated piece of 1” bsp pipe to get them all in line, then tacked them all in place. Same process as before with the D ring brackets that are welded to the rear crossmember. in some ways would have been easier to have started completely from scratch but I wanted to save as much of the original as I possibly could. 3 Quote Link to comment Share on other sites More sharing options...
the DT guy Posted June 4, 2022 Share Posted June 4, 2022 Not much to say just hours of laying down beads with 5mm rods. 1 thing I will say huge respect to the men & women who worked un godly hours pushing these big old welding rods. 5 Quote Link to comment Share on other sites More sharing options...
john1950 Posted June 4, 2022 Share Posted June 4, 2022 No one thought about the fumes coming of them either. Biggest ones I poured in were the old number 4's inside of a crusher. You are putting in the hours as well, but it really is coming together now. Is that a French truck lurking in one of the pictures? Quote Link to comment Share on other sites More sharing options...

john1950 Posted June 4, 2022 Share Posted June 4, 2022 I used to drive a Premium artic, basically a Volvo in disguise. Always gave better fuel consumption than the equivalent FM. But the electrics were another matter. I wonder what sort of fuel consumption you are going to get out of the DT and trailer freighted up.

the DT guy Posted June 4, 2022 Share Posted June 4, 2022 my truck is half decent i get between 10-11 mpg out of it, just put a new gearbox, drive line and diff in her bout 5K km ago so drive like a new truck know. she does have a really odd gremlin were i indicate right and sometimes the wipers come on but very inconsistent. in 2019 me and a mate went to holland with his c6 powered 981 with a sherman and she averaged 12MPG over the 1000 mile round trip. course you get to 30mph and you just sit there and cause your grossing 60 ton the weight for the most part is pushing you along. plus there are only 2 big gear changes to get from cruising speed to hill climbing mode and having no turbo helps as your not dumping more fuel in for no real gain.

john1950 Posted June 4, 2022 Share Posted June 4, 2022 I did not think you would get that kind of millage running at that weight. To get a like for like comparison an identical rig with a turbo or supercharger would have to run the same route on the same day. Todays trucks use a lot of fuel running ancillary's and the exhaust system. One of the Premium's I drove would sound the warning buzzer and put stop immediately for no reason, very disconcerting while motorway driving. When I got used to It was spot a pothole and give it a run through and off it went, it was like that from new. Any C6FSL that I drove in plant got through the work but were noted for being thirsty.

the DT guy Posted June 5, 2022 Share Posted June 5, 2022 helps that running so slow were not having to adjust speed all the time for traffic and on most big round abouts etc you don't need to slow down as you can coast around so there are lots of little fuel savings that way. to be honest it's the long hard pulls were the bulk of the fuel gets used as it takes so long to climb hills at 5-10 mph. the only issue we have ever had was a blocked fuel filter but luckily i can open the battery box lids and turn the taps from 1 tank to the other while on the move. i have heard the turbo and supercharged C6's were a bit heavy on fuel but that most also depends on how the pumps are set up. i know with the NFL you can wind the pumps out and chuck more fuel in but doesn't make much difference.

john1950 Posted June 5, 2022 Share Posted June 5, 2022 More fuel without extra air means black smoke. It's all about optimums, intake air filter cleanliness, air intake temperature, height above or below sea level, fuel delivery pressure, both low to the pump and high to the injectors, injection time and duration, and compression peak pressure. Then the person on the controls makes it talk or not. I only used to get 10 out of a Scania 420 auto running on 6 axles pulling a curtain sider over the hump to Manchester from the North East, It was usually fully freighted both ways. I could get 17 out of a manual ranger plus splitter 460 CF Daf running nearly the same route pulling a reefer but only on 5 axles running 38 tonnes down and 22 back. With a 420 Scania auto it was 12. With a C6SFL in a Vickers Vigor I used to use between 5 and 7 gallons per hour on dozer work, it was about the same pulling a 9/11 box. Depending on ground conditions. 1 Quote Link to comment Share on other sites More sharing options...

john1950 Posted January 28, 2023 Share Posted January 28, 2023 Hello, I hope all is well with you. How is the restoration of the Rogers going? Will we be seeing the combination out and about this year? Quote Link to comment Share on other sites More sharing options...
the DT guy Posted January 28, 2023 Share Posted January 28, 2023 Evening everyone I’m still here been busy with work and chasing a fuel pressure problem with the diamond t which has been annoying to say the least. But the Rogers is quite a way on from my last post and the running gear is nearly finished, just waiting on new break linings. all heavy fabrication finished on the deck. Shot blasting and primed in one very long day, started at 8am finished 3am following day. Few days later 2 top coats applied just before winter hit. Rear bogie pins cleaned, greased ready for bogies to be fitted. New steel for ramps and turntable discs. New ramps underway was going to make just 1 and try to save the original but just as much work in 2 new ramps so making a matching pair. Dolly frame and track guides in top coat, the dolly is know all assembled part from brake linings so very close. new rear brake casting which links the actuator rod from the chambers to the break drum actuator rods. Red is the pattern green is a original I borrowed Silver is the new un machined steel casting. that’s the Rogers up to date and hopefully start adding more soon. The truck is having the fuel lift pump gone through again as we think it has either a bad valve or a bent actuator arm, so waiting to hear back on that. myself and Jason Jefferies took our DT’s to GDSF last year so here’s some pics from that week but I’ll put a load in the Dt gallery from south cerney and GDSF in a bit. Enjoy everyone 😊 7 Quote Link to comment Share on other sites More sharing options...
john1950 Posted January 28, 2023 Share Posted January 28, 2023 Great to hear from you, I really needed a big restoration fix. As usual your welds are very consistent and clean. Have you checked the Fuel flow through the return from the top of the fuel filters, I seem to remember a relief valve in the filter block.

john1950 Posted January 29, 2023 Share Posted January 29, 2023 I presume you have checked suction lines especially any rubber ones for delamination. I am going back a long way but a Ford Thames with a 4D would pull for fun up to half throttle then die away, It was traced to a piece of straw in the fuel line after hours of work. You do have a busy couple of years planned Good Luck, I got pulled up the other day for asking for welding rods, they are electrodes the man behind the counter said. He was at least as old as me. Good fun. I have not been to a one before but I am going to a Military band concert with a friend in Dunfermlin today so about a 4 hour trip each way.

attleej Posted January 29, 2023 Share Posted January 29, 2023 Absolutely the only way of doing a trailer. Weld it up and then shot blast it all over and then paint it. It will last ages that way. When I had my DT I always wanted a Rogers trailer to go with it but one never came up and / or I coukld not afford it. What a fab job. I can't wait to see pics of the running gear go together. Seeing these pics motivates me to re-commission my big CF girder trailer in order to transport the Conqueror. On the fuel, are you certain that there is not a foriegn body in the fuel tank? Will it work correctly with a jerry can and a minimal jerry rig pipe system? Keep up the good work. John Quote Link to comment Share on other sites More sharing options...
the DT guy Posted January 29, 2023 Share Posted January 29, 2023 i had new bottoms put on both tanks and i have had a brown sludge in the filters so i think that sludge has gone through the lift pump and damaged the valves. i have know removed the original ww2 filter set up and fitted twin caterpillar spin on filters. i guess the tanks went a bit rusty n side while i was building the truck then it's got drawn through with the diesel? i have run the truck of a can with all filters bypassed and no difference which is why the lift pump is apart again, the truck runs perfectly just looses fuel pressure when the governor opens up. i didn't realize your girder trailer needed so much work john, i had a quick look over it when we were there in august. but yes there is only one way to do a trailer and that's back to the bare bones and go through the processes. thankfully my DT & rogers wont be living under trees or in hedges ever again hopefully. regards sam 1 Quote Link to comment Share on other sites More sharing options...
attleej Posted January 29, 2023 Share Posted January 29, 2023 There are four separate tasks on the 'Big Trailer' . First, I need to make sure that the radius of the shoes perfectly matches those of the drums on the rear bogie. I can swing both the drums or a jig holding the shoes (jig yet to be made). on my lathe. Second, I need to ensure that the steering system on the rear bogie is working perfectly. Thirdly, I need to insert a 27" extension piece into the middle of the girders in order that the Conqueror ARV can be carried without removing the winching spade which is a bit of a pain to do. Finally, it would be good to make a deck for the trailer by inserting cross members through the girders along with side raves. I have a proper design for this. This would make loading and unloading far easier and quicker. Sounds a lot to do but I have an exceptional team to help. Every alternative to the existing big trailer is horribly expensive because the Conqueror weighs 60 tons AND is 13' wide. I have already got the 25 and 38mm plate in stock for the extension. The Conqueror ARV itself is already nearly ready for Capel and is 'booked in'. I just need to finish the hydraulics for the spade and calibrate the winch. controller / display.

NZM305 Posted June 26, 2023 Share Posted June 26, 2023 Just checking in on how the big project is going John? Love seeing that heavy fab work. Quote Link to comment Share on other sites More sharing options...
the DT guy Posted June 26, 2023 Share Posted June 26, 2023 I’m still here John just been so busy with work I haven’t been able to spend time on the Rogers, but did manage to get the 2nd ramp together a few weeks ago. Also collected a NOS front axle for the 980 as I know the king pins are past their best and been collecting other NOS parts for other trucks waiting in the cue. Top hat bosses for hinge bolts machined ready to be welded in. glad there nearly finished just the outer hinge brackets to machine and weld on and handles to make and will be some were handy. Then a few minor NOS purchases to help keep the fleet going with more in the post 🤦♂️ hoping to get the 980 out this weekend so will get some pics of her out and go through some of the up grades I’ve done to her. 5 Quote Link to comment Share on other sites More sharing options...

john1950 Posted August 14, 2023 Share Posted August 14, 2023 I have watched the video several times, you have that gear box mastered. That C6 is sounding good but I do not think the fuel pump is quite right. I do not remember so much black smoke when pulling hard 900 to 1000 is their torque band, it was just a faint haze. It also seems inconsistent through the rev range, the black changes shades. Have you compaired it with another one? It would seem the air inlet side is good as there is very little smoke a high revs. You have to get them right or they give piston trouble. Have you another fuel pump to try on it? This is just my opinion looking on. You do fantastic work. Quote Link to comment Share on other sites More sharing options...

This is just my opinion looking on. You do fantastic work. good evening john, your correct with your observation regarding the smoke. the injector pump is know 100% but since this video i have removed the 3/8" fuel line which goes from the primary filters to the lift pump (postwar fitment) to a 1/2" line so the suction side is all 1/2" pipe know. this has solved my fuel pressure issues as the lift pump is know drawing the fuel through the modern CAT fuel filters a lot easier so i'm no longer getting the fluctuation from before. the issue i had was injectors 5 & 6 had partially blocked nozzles so she was running 100% on 1 - 4 and 5-6 were only producing half a spray pattern. these have been removed and cleaned and what a difference it's made having all 6 firing correctly. also i have turned the fuel on the injector pump back another 1/4 turn which has cleaned the exhaust up at full power though on a really hard pull she does still produce a very faint consistent amount of smoke. which i have been told by a couple of old school guys that is right for these NA diesels. drove her down to the Langport steam rally in somerset couple of weeks ago and went down the 303 with no issue at all and at the show i went on the tractor pulling sled and i never ran out of power just traction on the damp loose soil. so at the moment i think i have her bang on know and swapped the fuel filters out the other week. looking forward to getting the rogers finished and start running down the road with some proper weight on the back. 1 Quote Link to comment Share on other sites More sharing options...
