My White 1990 Caravelle Syncro

[Bruce]

My Busshmeide decoupler has always leaked.
When putting it onto my new box Richard my Mechanic noticed that there is a missing O ring or seal in between the housing and the decoupler actuator holding plate.
   
   

I know that this is not a standard thing but if anyone has a hint or clue how to stop the leak or has a similar decoupler and knows what size O ring or seal is needed please let me know.

I got the green O ring in the picture below with the Kit but I think it's for another part of the kit.

the green oring looks about right,if it does not work

get a seal with the correct ID for the shaft, have an engineer machine the casing to take the seal, you may need to remove the lip on the bracket, that looks like it is to hold the oring in place

That o ring is the seal for the shaft. Standard desighn on the Buschmiede decoupler.

Thanks Stuart and Russel.
Somehow that green O ring has gotten lost so I'll look for a similar one and try and make it work.
Thanks for the feedback I really do appreciate it!

[Bruce]

Sorry Russel I might be confused - which shaft are you referring to?

[Russel]

The decoupler shaft. The O ring fits into the recess around the shaft and is held in place by the lip on
The actuator bracket. Some of these setups do seep a little oil, as in leave a damp patch around the bracket, not dripping. To solve this you can machine the housing to take an oil seal. You need to remove the lip on the actuator bracket if fitting a seal.

Thanks Russel
That really helps, I will look for an O ring that will fit.

Got the car back today with the new box fitted.

Should have gone for the Ellermans Box right away, but you live and you learn.
Decoupler no longer leaks but is also not engaging 4x4 so that will be a project for next week.

Love your cartoon pic! Yes nothing like a Syncro to force you to stay gainfully employed just to run the beast!

Glad to see I still have a ways to go.
