    another Diamond T 980 restoration

    blimey done a lot since the last update though hasn't felt like it with work. right the winch is mostly back together part from the control levers need fitting and the drive from the aux box needs painting and fitting then the winch as a whole will be finished. pull 1531 out side to fit the winch and trial the replacement bumper. new linings riveted to the original break shoes and installed to the truck then adjusted up. front bumper and rails cleaned up and are now all away being blasted and painted by a friend. while waiting for a load of parts to be painted the rolls is now stood up with gear box removed. the gear box is mechanically very good and was full of clean oil with no water in it which is a huge relief. 1st gear has had a harsh life as the teeth have been ground away welded up then ground back though being a training truck that is probably no surprise. ounce the gearbox and pressure plate were removed yet more evidence of the trucks hard life were to come to light. the clutch disc centre has been bottoming out on the flywheel crank bolts thus worn the heads down. also with the pressure plate removed the clutch disc friction material doesn't even touch the flywheel at all!! so when the clutch is engaged the pressure plate is bending the clutch disc, so the clutch disc is no good and the pressure plate has loads of hot spots and star cracking so they will both be replaced. looking at the flywheel closely it has been messed with as it has a steel ring welded in so some one went to a lot of trouble to machine the fly wheel out then weld a ring in which i guess is not very hard as it has a 3/16" wear lip which enplanes why the clutch disc is bottoming out on the crank shaft/flywheel bolts. even some of the welds have clearly failed to so glad i pulled it all apart as it would have made a royal mess if i drove it as it was. if any one has come across this practise before would be interesting to hear of your stories as i assume this was done by the MOD? moving swiftly on have removed all ancillaries from the engine ready to start cleaning it up to paint, will be compression testing the cylinders to see what they are like and managed to get the injectors out with a heel bar and a piece of pipe. almost rearranged my good looks trying to get the injectors out but got there in the end think i was very lucky they all came out and the brass sleeves remained in the heads. so will get them reconditioned locally. as i am at the cleaning engine phase any recommendations or advice on best way to clean the engine ready for paint? have scraped the worst of the oily crud off so got to deal with the multi layers of paint and general greasy residue left on the block. regards sam

    Wanted: Rolls Royce super charger

    quite a lot of differences but is there any reason you couldn't put the super charger straight on to a NFL and adjust the fuel to suit? the gear boxes will be fine as the Wynn's diamond t's ran 220 cummins with no issues and some 980's have rolls royce eagles fitted with no issues and i no of a 320 cummins big cam driving original transmissions with no issues. week link is the single plate clutch i think. if you don't think it is wise to fit a super charger to a nfl then i will leave it as is, just assumed they were the same engine just with the charger fitted/removed.

    Wanted: Rolls Royce super charger

    good day radiomike7 I would like to uprate the c6 nfl in my diamond t 980 if possible. I didn't know compression ratio is different thought it was just fit supercharger and alter fueling. Any advice or info would be greatly appreciated. Regards sam

    lots more progress on 1531 i have pretty much all the air lines fitted to the truck know part from the winch clutch and trailer hand valve lines. as the truck is generally up together. know i have made a start on the winch which luckily is not seized apart from the 2 control levers but a bit of heat and they are starting to move. the 400 odd feet of winch cable is not to bad but i will be putting a whole new cable on as it is not something i like to assume is going to be ok when winching hard. aiming to turn the winch around in about 2 - 3 weeks then my sights are set on sorting out the Rolls Royce C6 engine so starting to get into the interesting bits know. regards sam

    making a lot of progress on 1531 know, all the wheels are built up and fitted, the range box is finished bar fitting the new top cover. the hand brake mechanism is mostly in i just need to get the shoes/pads lined and fitted. almost at the stage of choosing to start either the winch or the engine. hopefully tomorrow will be another good day so should have another up date coming shortly. regards sam

    a lot has happened since my last post the range box is know back together and installed into the truck, both air tanks are fitted and have got the rear wheels fitted so 1531 is know much easier to move about know. also farmed a lot of the painting out as it was easier to get all the small fiddly parts sprayed than waste a lot of short day light hours painting with a brush. the header tank has come back from being repaired as it has been frosted in it's past life and had a 5 -6" long crack that has know been welded up and just needs a few little jobs doing to it then it can be painted as well. there is a load of small parts that i can get on and fit then ounce i have tidied up the parts i have painted i can move onto the engine and winch. at the point were every part that goes on makes a big difference to the look of the truck know which is such a great feeling, also today marks exactly 1 year since i started taking her apart. regards sam

    thank you doug it is great to have a decent amount of time off to be able to get loads done to the truck. succeeded in getting the range box in bits today, one selector shaft was seized and every thing on the out put shaft was rusted up from the flange nut right down to the bearing. generally very good condition all the gears and bearings appear to be very good so it should just be a clean/paint reassemble exercise. tomorrow will check what is good or bad and start cleaning & painting.

    Christmas holidays have started so have 2 weeks to spend on the Diamond and not wasting any time getting stuck into the long list of jobs. started with refurbishing all the different air valves and switches for the brake system which only needed cleaning as all were internally very good with no perished diaphragms or bad springs. also stripped the radiator as i am making one good rad out of two as i wanted the header tank with the "DT" emblem but that rad had a bad bottom tank so a lot of work but worth it. lastly i started on the range box this evening which had water in it which is no surprise at all with these and the gear set is very good being the upgraded helical set which was fitted to most Rolls Royce powered Diamonds during the upgrade process in the 50's - 60's. hopefully it will be just a simple strip down, clean, paint and re build. that is 2 days down 12 more to go can't wait to get back into the shed.

    to answer doug's question we use a steel plate equal in thickness to the original tank in this case 2.5mm and i make it big enough so that all the weld is on good thick base metal (tank). in this case a 2" x 2" patch which i curve so it matches the radius of the air tank and helps retain strength. then i just do a single run all the way around with a stick welder at around 35 - 40 amps which gives good penetration with out under cutting. in the UK it is very common on older vehicles to see patched air tanks or brazed copper air lines etc. i know were BlueBelle is coming from but from working experiences with steam boilers which i have hydraulic tested old riveted boilers to 300 psi which have a working pressure of 200 psi in steam. these boilers have known thin spots like 2 mm thick or less and a hydraulic test does not make the boiler fail and that is fact they always fail when hot and when they do fail they just drip and hiss. either way i know the air tanks on the Diamond T are sound and i know to keep an eye and a ear on them as with any old vehicle. i have seen air tanks on another diamond t with braze repairs and never give a problem. of course a repair is only as good as the person who does it. besides a modern air tank is only 1.5 mm thick when new and the tanks on the diamond t are 2.5 mm thick and run at a lower pressure than modern trucks so i can't for see any issues.

    the air system is 110 psi and is perfectly safe and if you go worst case scenario you would just hear air leaking out. the air system on a truck does not have to be in test, the air tanks on a truck are not pressure tested they either hold air or they do not. i build steam engine boilers for a living and i have seen boilers hydraulic tested to 300 psi or more and even when they are down to 2mm of thickness and they don't leak or fail. worse they do is start to drip or hiss and not much more. trust me if i thought they were no good i would have scrapped them but having had a boiler inspector thickness test, put a camera inside and pressure testing them to 150 psi on air they are sound part from one spot were it had managed to make a hole which the inspector said to patch it as it is a very common practice. thank you for raising the questions though as it is nice to see someone taking an interest in these things. regards sam

    not a lot of bolting parts to the truck at the moment as at the stage of just cleaning and painting various parts ready to be fitted, have sent the wheel rims off to be blasted and painted. last few days have been spent repairing the air tanks as there were some pin holes and small area's of pitting which i have built back up with weld. this after noon i also got very lucky and a very nice gentleman, Graham Upchurch actually photographed 1531 at the 1991 Knowl Hill steam rally and boy doesn't she look so much better back then.

    cheers John can't wait to get her rolling again. lots more work done on 1531, rear axle hubs have been swapped around so the wheel studs are on the right side and very surprised at how clean the brake drums and shoes are in side as they have been sat in the box for over 70 years and never turned a single rev. started on the winch rope tensioner mechanism as it is completely seized up so will need a lot of work to get it back to a usable standard. finished the weekend off by getting the last rear axle in to 1531's chassis and really looking forward to breaking the 8 rusty rear wheels down for blasting & painting.

    another Diamond T 980 restoration

    thank you very much Pete i am not a fan of electric technology bad enough the diamond has lights etc to wire in! got the first rear axle in today which is not as simple to fit as you would think specially when doing it single handed but got there in the end just need to top the oil level up and paint the hubs/break drums. the rest of the axle/diff i will leave as it is as it would be criminal to paint over all that original 1945 olive drab paint which has survived for so long so it will be painted with a oil/paraffin mix. the second axle needs reconfiguration as it is turned 180 degrees to the first axle so the left hub moves to the right and vice versa so i got to swap the hubs rounds so the right & left hand wheel studs are the right way round. also the drive flange needs removing and the bearing dust cap fitting then it is just the simple task of following the same process as the first axle. plan to have 1531 rolling on all 10 wheels by new year so should manage that goal. regards sam
