another Diamond T 980 restoration

Recommended Posts

Wow, Sam,

you have plenty of work ahead of you!

 

The loose bearings in the top of the diffs seems fairly typical (to me) in both the 4 ton and 12 ton Diamond Ts and the WLFs. It seems to be due to poor lubrication of that section of the diff. If found soon enough, it is a (relatively) simple job to just replace the two bearings, but then you have to check the crownwheel/pinion adjustment. I notice that the bull gear is helical cut, whereas the 4 tonner has straight-cut bull gear teeth.

 

Question, are you doing riveting? If so, I'd be interested in seeing pictures of the process you do and a description. It (hot riveting) is something I know nothing about.

 

I look forward to a steady flow of pictures and descriptions of this trucks' revival.

 

An interested . . .

Hi Sam

 

yes i do hot riveting i got a friend to take some video riveting some of the plates back into the front of the 980 chassis, are you on face book? i can link the vids to you on there and you can see exactly how i do it.

 

more done on the 980 this weekend, the last of the brakes are removed with the last "S" cam being very resistant which resulted in lots of brute force and using tapered wedges to draw the cam out along with the bushes.

next stage involved removing torque rod pins so the 2 axles can be removed in order to remove the spring assemblies as the springs both sides are no good. the first axle came off no problem what so ever, the second axle started good then went south quickly. with the last pin needing to be cut out with the gas axe which took all of 2 minutes to do then dropped the axle down onto a pallet, with this done the spring packs were removed with ease. all that remains is to remove the torque rods from the chassis and pull the pins on the front springs and the dismantling phase will be sorted. then the fun starts :-D

Hi Sam

 

Yes I am on F/B but I never use it other than for videos.

I don't know how to connect you to it.

put the weekend to very good use, managed to get the torque rod pins out in the end. i know see why people say leave them alone! but they had to come out regardless so onwards & upwards.

today (sunday) was dedicated to building up the really bad area's of the left chassis rail. in places small holes were starting to appear but after 8 hours continuous stick welding/grinding every thing that needed to be done is so. next stage is to let in the 2 plates into the top of the rails were they are very fin and that will be most of the bad jobs done and dusted.

hot riveting is a great team building exercise, you really don't want to get it wrong!

 

hoping to set up a gopro or something when i am ready to put the gusset plates and rear cross member in.

 

do some sort of long vid (movie) riveting it all back together.

 

the next truck i do will have to have a much better chassis i think!

Hi Sam,

Great work! I had a look round your truck a while back when it was in a sale.

I'm really glad that it is being brought back to life, fantastic stuff!

thank you handy1882 for the positive comment.

 

when i viewed the truck i knew it needed saving the poor thing was very close to no return as the cab isn't really salvageable and the chassis was in a very poor state. i would think another 5-10 years out side and she probably would have broken in two.

 

still 1531 will return to the road soon!

after noon every one

 

have got all the welding finished this weekend decided to build the R/H chassis rail up in the end as i just knew i would regret leaving it alone and it would be to late ounce painted. also finished riveting the front pintle hook member in while the chassis was on it's side and next weekend i am out with the 969 for the first time which shall be a welcome change. then will be drilling holes and riveting lots of metal together and getting ready for shot blasting and painting.

spent this afternoon fitting the new gusset plates and got the strengthening angle bolted into the left chassis rail.

 

hope to do a bit more tomorrow evening and get the strengthening angle fitted to the right chassis rail.

a nice cool day to do lot's of productive work, rear cross member test fitted with new side angle support's drilled & prepped for riveting on, before it goes into the chassis for final fit. followed by 1 1/2 hours riveting the gusset plates and the inboard support angle iron in place. ounce chassis work is done i got to replace the trunion shaft as the bearing journals are shafted (pun intended lol) so 1531 will have new shaft, spring carriers and rear springs.

new trunion shaft, springs and carriers for 1531 as all the original parts are either worn out or heavily corroded so replacement is only option. this will be next job ounce chassis work is finished.

cheers John got to keep up appearances

 

got a lot more done this saturday than first planned, all the little tidying up jobs are know sorted like re tapping holes, grinding welds and removing the last few small items. finally finished riveting the rear cross member in and riveted some of the ballast box mounts back on, these were badly corroded from living out side for so long resulting in 5 of the 10 being scrap. but the 5 ok mounts are good enough to go again and the keep some of the truck character.

to finish of the evening me and dad tackled the trunion shaft which in the end took longer to get the pinch bolts out than to cut the shaft out of it's housings!

 

pinch bolts removed

attachment.php?attachmentid=125838&stc=1

cut the ends of the old shaft to save the cast oil filler elbows to reveal these hemp elements which hold the oil like a sponge for lubricating the rear spring carrier bearings.

first section coming out nicly

attachment.php?attachmentid=125853&stc=1

a nice clean bore which just needs a good hone before receiving the new trunion shaft.

attachment.php?attachmentid=125854&stc=1

attachment.php?attachmentid=125855&stc=1

 

i think i have another 3 weekends of work then the chassis can go off for blasting/painting and can then start putting it back together again. still hoping to take 1531 to south cerney this year in rolling chassis form finger crossed.

Hot spanner does have its uses. Comming along nicely, each success is a battle won. Your hard work will pay of on the first drive.

thank you for your positive comments John got a long way to but can't wait for the first proper drive.

 

1531 has been in the yard 6 months and finally her chassis is ready to be blasted & painted not sure why it has taken me so long? front axle is strapped to the operating table ready for tomorrow hoping it isn't as bad as the rear axles!

 

replacement ballast box mounts under way.

front axle ready for dismantling tomorrow.

Interesting thread keep the up dates and photos coming.

 

I'm impressed with the frame repair work and the hot riveting, did you hire the gun in or is it a piece of kit you already have ?

Sam well done , I take it the DT has taken restoration preference over your Fowler , I enjoy following both , so keep going !!

we expect to see the chassis suspend towed behind the 969 please :cool2:

hello pete

 

the rivet gun is ours as we over haul and build new steam boilers for traction engines, which is one of the main reasons i took the 980 on as i couldn't see any one else sinking the time into saving it.

Hi John

 

yes the DT has taken priority over the fowler but over the winter i have got some good friends who are going to help me out by doing all the small niggly jobs. As it is connecting rods and valves to sort out and "capetown" will run.

 

I have every intention to suspend tow 1531 to cerney which is why i am going to sort the front axle out asap.

 

are you going to be attending cerney this year with your ERF John?

I guessed as much Sam, watching your video it was pretty obvious you guys had done this sort of thing before.

Full marks for taking on the task with the 980 I'll look forward to following your updates.
