Embrayage 10"1/2 (265mm)

[asaphelps]

Bonjour à tous, je ne parle pas français et je suis en utilisant traducteur google! Soyez patient, s'il vous plaît ...

Je suis le propriétaire d'un VM 90, 1987, moteur 8140.27S, boîte 28022, et Borg & Beck embrayage 9 1/2 "(240mm) poussé, et je voudrais installer l'embrayage plus robuste 10" 1/2 (265mm) poussé .

Ma question est la suivante: en plus de changer le volant moteur avec celui de l'8140.47 (il est à mon boîte?) Quelqu'un a le numéro IVECO de l'embrayage / plaque de pression Poussé 10"1/2 (265mm) à l'ordre?

j'attache fichier, mercì

hello Ric and sorry for this late answer, i'm not very often around here as I used to be.
I'll continue in in English if you're more familiar with it ...since I do not know where you're from ?
or in french, up to you.

you have to know that the mecanisme of your clutch is located and fixed to the thick heavy metal disk output of the engine and that if you want to put a clutch with a different diameter, the mecanisme will not have those fixations holes with thread at the right place and not the locators either.

you could then think it's just a matter of finding the right output disk that goes together with the clutch.
but then you may encounter another problem : the crankshaft on wich it is mounted can be different from one sofim engine to the other and it may not fit either.

I have had already that issue once:

I had a brand new engine iveco 4x4 with a pushed clutch with the 265mm diameter and I wanted to fit it in another iveco 4x4
at the time I didn't even know that it existed some pulled clutch on those, and that one was one of them with diameter 240, so the small clutch wouldn't fit to the output disk of my brand new engine !!!

I had either to change the gearbox as well to fit a pushed clutch... or change the output disk...since I had the one from a pulled clutch 240... but to my surprise it didn't fit the cranckshaft !

last option was to check if it exists pulled clutch 265 at iveco... and it does, I left in an iveco garage my output disk so they could surch for it, and in the mean time I've been lucky enough to find one brand new for a little price.

but in your case it's different because you want to fit a bigger one without changing system or engine... so you can always try to find a output heavy disk for the 265mm one but make sure the number of teeth fits with your starting engine and that it fits to your crancshaft.

that's all I can say about it.

If I find the topic where I already put pictures of those i'll put the link here.
I think on top of it the last time i talked about that was for an english talking person too.

that should make it easier to surch for it too.

here it is, that doesn't help much you just get to see pictures of both mecanisme and clutch disk but not from the output disk of the engine.

viewtopic.php?f=7&t=2958&p=33304&hilit=clutch#p33304

but reading again at your mail i see that you understood already the need of changing that thick disk...just one thing is not sure: will it fit the crankshaft ?
maybe you can see the references of the clutch on the picture...it's quite common around here and i don't think you would mistake if you go for a daily pushed 265 clutch from those years.

Thank you very much Hippo for your reply! English is just perfect, although I'm from Italy..

It is very clear that there are some doubts!
Also because I'm going to change also the gearbox going to fit one of the most recent 2826.5 gearbox with overdrive gears...

The only thing I can try is to find a flywheel of an 8140.47 and count the theeth on it and check if it fit my 8140.27S.

Then if I've correctly understood you have found the 265mm clutch "push" type, so it can be mounted without converting to "pull" type clutch.
Maybe you have the Iveco part number of the 265mm "push" type clutch?

But the 2826.5 recent gearbox will accept a "push" type clutch? Or, as the more recent setup is the "pull" type setup and for sure the 2826.5 gearbox will work with it, will be convenient to buy "pull" type mechanisms and go that route....

Sorry for the big mess, I've found also here some indications (in german) http://privat.albicker.org/iveco-gast/k ... riebe.html

Thank you again

not only the teeth, but as well the fixing of that disk on the cranckshaft of the engine... that's where it went wrong for me and I couldn't think of opening the entire brand new engine to change the crankshaft and find out maybe that there would be another issue again further...

no it's actually not exactly it: the van was originally a pulled type ... so I had the gear box designed for the pulled one... so I couldn't fit a pushed one also that's what I had on the brand new engine... so I managed to find a 265mm pulled one that fits the engine instead of the 265 pushed one... and works with the pulled mecanisme of the gear box I had in place.

note that later on another iveco daily 4x4, I had to change the gear box that was broken , that was a pulled type and I replaced it by another pulled type from another daily 4x4...and to my surprise, the clutch câble was on the oposite side: left side on one and right side on the other ! different clutch fork... different extra bracket on the engine to hold the end of the clutch câble... sometime even changes that seems easy can turn to scratching your head to figure out how to solve it...

anyway, yu're talking about overdrive too and I suppose the iveco you're taliking about is not a 4weels drive is it ?
not that it matters much for your concern anyway... I just wonder how come you ended up here, comming from Italy where those iveco comme from, I suppose you ended up as well on some Italian forum ?

don't be sorry, but actually we're not very aware of the different types each one of us have depending upon the model...
I have happen to notice those differences and ended up mixing parts from different models from different years but didn't find any logic that could lead me to tell whats mounted on what. it seems though that the most recent are pulled type when the older types are pushed, as you mentioned . and I just found that it could only be better to replace a 240 pulled by a 265 pulled since it's mounted on more powerfull versions, it could only be stronger and more torque transmissible... and I think that' s your intention as well.

Thank you for the clarifications..

About the Van it is a 1987 WM 40.10 4x4.
I've found that there is the option to have overdrive gears on 2826.5 gearbox (I: 5.093, II: 3,202; Ⅲ: 1,858; IV 0.82, R:; 1 V 5.69) instead of the shorter one, and actually is economically convenient to change the transmission rather than the axle gears.

I hope I will solve the clutch things soon as I will do the job...

Thank you

alright, you did mentioned what van you have in your 1st message actually.

I didn't know there was different daily gear box ratio , that's interessting indeed. where does yours come from ? what daily model ?
