Propshaft spring (Solved)

[Sutty2006]

I’ve never seen one of these before, but I’ve ordered a 4 speed spring for my B series. Come to fit it today but unsure if it’s supposed to sit inside the imput tube or simply up against it? Can anyone enlighten me?

It’s supposed to go inside, the spring you’ve got there looks too large diameter.

[Sutty2006]

Thanks John. I’ve messaged the eBay seller to query it.

sits on the inside. you may have been given a 5 speed one ?

[Sutty2006]

Have made enquiries with the sender. Awaiting his response.

not on a 4 speed it shouldnt .it fits into the end of the gearbox on the splines and goes inside the gearbox. prop then presses against it to keep the centre prop against  its rear stop.

Take it your 4sp manual, have one here, can measure and photograph if needed?

I made the same mistake recently, spring should sit inside the splined sleeve. I ordered a handful of springs, got some left if you need one

Of the right size, I should add..!

When I pushed it into the rear of the gearbox, it just didn’t feel natural. If you get me. I had to use a magnet to fish it back out. It’s a lot to compress in that area.

the one fitted to mine is the same as your first picture. large spring. fits OVER gearbox end splined shaft.

it does on mine anyway. 

are you sure theres not a spring already in there ? they rarely fall out ?

Yeah there’s no spring in there at all. I’m happy to try putting this one in if it’s right, just need to be 100% certain as don’t fancy damaging it or anything else. 
 

someone will have a genuine 4 speed one they can check for me. External diameter of this spring is approximately 32mm

i have a few spare ones and gearboxes to check in the shed.will look tommorow and maybee some photos. 

can look for the carlton blower if you still need one too ?

In Haynes we trust..

Seems Opel are at it again, as I've one car, one gearbox one spring. 2.0 4 speed. Never messed with ....

 

71mm x 31mm, slips inside gearbox, and sits on top of prop, see photo. 

If fitted you will see it brings prop back to your seal mark half way. On shaft input.

Prob better using wire wool on shaft once happy, and change rear seal. 

To be honest I might fit one on the inside also, should be able to work out correct length. 

[Sutty2006]

How odd!! 
 

looks to be correct then? There’s a new seal on the gearbox anyway so I’ll get the end of the prop cleaned up better just in case. 

I know one man that’ll confirm it @MrCarlos is the ultimate guru on these things…. 😁

Been looking on some German websites and seems the 4 speed spring is indeed bigger than the 5 speed spring. The 4 speed spring goes as mentioned somewhere above over the spline into the gearbox while the 5 speed spring goes into the splined tube of the prop:

4 speed:

I wonder if the 5sp spring will work also additional over engineering 🤔🤣

[Sutty2006]

Brilliant. Thanks everyone! 

[Jessopia74]

Interesting stuff👍
we need a ‘solved’ option for OP so that it will help in future searches 

[IanG]

Ahhh what about the auto box, does that have a different spring as well, about to get my box changed so would be good to know  

[H-400]

While I was looking on those websites I checked Edelschmiede and no spring mentioned, only the manuals. But to be sure one of the auto-box owners on this forum can help you to be sure.  Found also why the is spring fitted, I thought to keep the vibrations as low as possible but came across this explanation: The spring pushes the prop to the rear to be sure the shaft in the rear axle tube (steel Manta A, alu Manta B ) doesn't jump out of the splines where this shaft enters the diff. 

I know the rubber donut in the crossmember is flexible so yes I'll keep that spring where it belongs 😁

[cam.in.head]

ive checked in my spares for you and the spring definately fits in the end of the gearbox. not a tight fit in any way thou but just slides in past the oil seal. definately not inside the splined end of the prop .you can see down inside with a torch.make 100% sure theres not one akready in as it may be hard to get out !

my auto one is also very similar if not the same .

[®evo03]

Turned my gearbox upside down, good shake and it drops out, now try doing that with engine and box in place. 🤠 

But I think I remember pushing shaft into gearbox and loading spring, then pulling shaft out, shot out like a bullet. Then put it back into output for safe keeping. 

[Sutty2006]

Yeah there wasn’t one in mine, i rebuilt it last year and nothing fell out.
