have spent many a happy day repairing ZF Gearboxes …Will agree with Bking (which is a first )they are pretty chocolate…But I get the impression rightly or wrongly that he hasn’t ever overhauled a gearbox,but likes to jump on the bandwagon of what is and isn’t good…A majority of issues on the ZF 16 and 8 speed boxes ie 3rd gar synchros are according to ZF down to driver abuse …Since in warranty I have to follow their guidelines ,then I agree…The new 6 speed box has carried over the bearing issue from the old 6 speed box sadly…
I have heard somewhere Merc where using a ZF box which suprised me to say the least .wether it is true or not I do not know.I thught Merc did their own…But Volvo also use ZF boxes a well so you never know
Nah never dared touch inside a gearbox I leave that to clever [zb]s like you.

I run a trailer with bpw springs, the problem is when a spring goes loaded the axle tend’s to go with it!
whilst I have never had this on a bpw axle it has been a problem with ror and smb axles in the past
Hi,seen many a trailer roll in the yard ,axle sideways,suspension on its arse driver none the wiser ,lay in a few ■■■■ wretching laybys to change a loaded trailer with a spring gone,airbag then rubs thru on the brake drum ROR. Most of our damage comes with drivers charging onto raised weighbridges or turning on a sixpence and literally tearing the leaf,1st they know got a problem is when they loose air cos of the bag going.Still got 1 fruehauf with SMB discs = what a nightmare soft as [zb] ,cant let it out without a tractor with a retarder or it will crack discs .Saf ar413 with thick twin leaf bulletproof but like everthing else that works its replaced by inferior product.
What your trailers aint got a protection valve for the suspension.
Your trucks must be called dobbin or eyore.
Well norb as you are the font of all knowledge maybe you can explain to me why the likes of mercedes etc use reduction axles when they only run at 90 to 93% efficiency when crown wheel and pinion diffs run at over 98%.
Prey tell?
richmond:
Bpw on drums, excellant , we have half the trls on ror and half bpw, wont be buying anything now unless it has bpw drums, unbelievably good and reliable.
Hi,you had any trouble removing the hubs on the eco2?
Yes you got to pull the circlip pull the hub lock(fine thread) and fit the stub dolly and extractor, ([zb] tight) if you need the puller let me know.Dont pull the stub with the bolt it screws the thread and the axle is goosed.Crap axle compared to the standard eco plus.
Try wikopedia cos lets face it you know jack,oh norb why do you use prime numbers on diff ratios, just questions i thought some dumb bugger like me learn might learn from the likes of folk like you .Have a nice day.

Norb I recieved your “Message”
You “trained” as a “mechanic” for 12 years in the army?
Dont make me bloody laugh.
Worked for both the US and UK army and their "mechanics"are a [zb] joke!
Worked with army “mechanics” for private companies and usually they make the tea.
Like a lot on here they talk a good job and know sod all.Done this job 40 years and dont need some bloody cannon fodder or btec ■■■ to tell me how it works.And no I did not “serve” in the bloody services.The trucks I worked on had to earn a living not sit on a parade ground and turn a wheel twice a bloody year.
So when a bag goes it dumps the brakes?
Hope you dont get a tug by VOSA.They like to see a predominance valve on tank 2 usually or …
Oh god another “expert”

owner account driver…just do as I do now and just ignore burger king,he isn’t worth the time and effort.according to him in one post im a ■■■■■■■■ ,then in another i’m a know it all smartass ,just because can strip and repair gearboxes …And I had even said that I agreed with him to an extent
If people ignore him and do not respond to his posts he may well go away …He isn’t here to contribute and assist those who have a genuine question etc …
He just comes here to try and belittle people with way more knowledge and experience ,1 example being the turbo thread ,where he is still adamant he is correct.
I bet the lads at tescos where disappointed when Waitrose turned him down.I bet he’s as quiet as a mouse at tescos
Merc for me too.
I wouldn’t be frightened to go discs, the technology is improving all the time. They are more simple than drums and are a lot cheaper to run nowadays. People pushing for drums do you cost in the extra wear on them since going on to non asbestos drums. we were lucky to get 3 years out of a set in the end, that’s before you get the less efficient braking etc.
This was on hard, hillly tipper work hauling salt potash and in and out of quarries.
The merc disks on a local tipper trailer are costing far more to run, whilst they do stop well they are open to abuse! the trailer has gone trough a full set of Alcoa wheels at £320 a pop, countless disks, axle pivot/spring hangers cracking, just started to replace the main axle pivot bushes, oh then there’s the pins in the callipers, 1 has a cover to keep muck/general dirt out the other is open to the elements!
I ill admit this trailer is behind a truck also on disks without an engine brake/retarder, don’t think we will see 3 years on a set of disks in the memory of man! the vented ones are cracking iro 6 months
the other trailer with the same axles though not being in service as long is behind a truck fitted with an engine brake and the disks do last longer, on the plus side we can weld a cracked hanger in the garage, when a spring broke loaded on an ror type axle down the road you had major mither!
The technology may be improved but think for one minute it’s over 40 year’s since man last set foot on the moon yet for some reason the sliders on callipers only have a bung/cover on the end of one, out of 2 in many set ups can anyone explain why?
I have 3 aggregate trailers running on saf axles, they are the off road SKRB 9022K 9 ton axles, the trailers are 9 year old and the only thing i had to do to them was to replace the 3d axle bushes at 4-5 year old, and i replaced 3 wheel hub units between the 3 trailers, if you go for disc brakes make sure to get knorr bremse calipers and get the calipers that have the both guide pins sealed, my trialers have SK7 knorr bremse calipers which have the top and bottom guide pins sealed and they never seized up, you could park the trailer up for a year and if you took the pads out the caliper would glide freely on the pins not like the SB7 and SN7 knorr bremse calipers if left for a while they seize on the unsealed guide pin as it open the elements and it rusts and corodes. I know several bulk hauliers that run merc axles and they have told me that the axle hangers crack and give trouble and new hangers have to be fitted, one haulier told me he had to replace all 6 hangers on a 3 year old trailer! all the bulk tippers he has purchased in the past 2 years have been fitted with SAF axles because of the hanger troubles with the merc axles, SAF are now produceing their own calipers but my advice is to stick to knorr bremse as they are tried and tested, saf drum brakes are also excellent brakes as i run them before and they gave no trouble, the saf drum brake isn’t that much heavier over the disc either, SAF do a heavy duty off road axle now called cd design (custom design) if you ordered a bulk tipper with these cd axles along with the drum brakes you would have a good strong running gear. click on the following link ww1.safholland.co.uk/quicklit/SA … _en-DE.pdf
this would seem a good post on the subject in my opinion!
though the saf 3d bush is only maintenance free till its worn out, merc and saf fit the same bush on the lighter duty axles, I have just made a tool to fit them
if this is a heavier duty axle the bush may be larger, the only other problem I see is operators moaning about tare weight of better built axles.
after all trailers are spec/built lighter and lighter these days then operators expect to put more weight on board then moan when they start to fall to bits!

Went for an interview at a large supermarket distributors the other week as a “truck mechanic”
(been doing fleet work for 35 years)
They emailed me tellin me I didnt have the right “attitude” and my job application had failed
Your record on here proves that you only seem to know about what you have had personal experience of.
There is more than one way to skin a cat. The 35 years of fleet work has not helped you.
Yes it has and the main one is to not suffer fools or stupidity.Life is way way to short to listen to their crap.One must question what is accepted as “knowledge”
Just to add my bit.
Trailers not used so much are on bow drum, don’t give any trouble when park up for awhile.
Got c/f tipper on smb disc where always sticking. Drilled and taped bottom pin slider and put in grease ■■■■■■ and grease now and again, no trouble since.
Ror disc always replacing because of exciter ring rusting out, so abs light on.
Got c/f with merc axles, just had new set of alloys, wheels cracked but brakes ok.
Just having 2 c/f on latest saf so see how we get on.

Hi 3yrs in the NE, id be over the moon with that on local tip work,in my experience an axle set of duron /ferodo/kb pads will cost £90 brake shoes x4 from £11 to £20 a shoe .A Saf disc at non oe is £75,drum from £42 ROR to £60 saf/bpw , calipers £300-700 quite a bit more than a camshaft n bush kit yes cant argue brake performance is better when needed but find drivers are causing a lot of disc problems by braking heavier and a lot later funniest thing salesman say is they are lighter cos there isn’t a drum my back will testify them calipers are not exactly light.
Bking:
Self leveling valve and ■■
Air brakes are isolated from suspension last time I looked.
every trailer must of been built wrong that ive been out to with a burst bag then as the spring brakes have applied after the driver has stopped must inform C/F ,WILCOX SDC,DONBUR,WEIGHTLIFTER(RUBBISH),KELBERG ETC ETC. thanks.
