Hi Richard,

I went with AA Transaxle.

He had them in stock and was easy to contact and deal with - their kit is excellent and you could fit it yourself if you are handy with spanners.

Check: http://www.aatransaxle.com/price_list.htm

Cheers,

Skot

Hi all,

I'm sure this has come up before, but any comments on which decoupler to get, and the best source?

I know there are quite a few suppliers about, but is there a good reason to got for the copy of the factory design or the US design?

Thanks for the replies. I'm happy to do the install, seems straight forward. Like wise I am mostly in 2WD, just drop the tail shaft in/out as required currently. In fact 2WD with diff lock gets me everywhere I need to go, but AWD is much nicer to drive on loose dirt roads.


No one has any recommendation on the factory copy compared to the USA design? They are quite different, but no idea if one is better than the other. I also like the idea of the stainless brackets and push rod some offer.

PS Skot, I have finally sourced a factory (2WD) fuel filler neck, so hope to install the tank soon!! I prefer the look of the factory filler

to the usa and the postage back of the decoupler had mine fitted by Steve Muller app $900-00 so all up about $2000-00, i was talking to Paul Muller the other and he said that he will supply and install a decoupler for app $2000-00, mine works fine as you tend to drive in 2 wheel most of the time it has a easy life. I suppose you take the risk if the O/S unit fails and you have to ship it back to buying in aus and having the supplier work it out.

Richard,

Apparently the AA transaxle unit is the same design as Florian's but I found Florian impossible to contact.

I love my extra tank - it is an excellent piece of kit.

I like the 2wd filler unit too but cutting that toothed opening in the side of the van is something that I couldn't cope with,

Cheers,

Skot

In terms of function, there are two types.  One has a needle roller in the extension housing at the nose of the gearbox while the other has a plain bush.  The needle roller is mechanically preferable.

Richard,

I bought mine some years ago from Germany (with roller bearing) - not too hard to install.

The Company’s name slipped my mind. Something like “We get your Syncro in the bush”?

Ken may remember.

However they also want the core housing in exchange.

 

Cheers,

Theo

Thanks again. I have read a lot of posts on the net of opinions, but that is all I have to base a decision on. From what I have read the factory copy uses the needle roller, but that really only spins when you have a big speed difference front to rear (in reality should be rare/unlikely). The US design however is a stronger "coupling".


I managed to get a spare nose cone, so at least I can send the core up front and not have the bus off the road :)

Hi Richard,

my experience, I received the parts, installed them and send the nosecone back to US. once it arrived there my core deposit was refunded.

Richard,

The decoupler shaft runs through the extension housing and connects to the propellor shaft.  The propellor shaft drives the front diff.  While the road wheels are turning, the propellor shaft is turning and in accordance with the road speed.  There is no speed difference front to rear when running straight and only a very tiny difference when turning.  In practice, the prop shaft is running all the time and with only miniscule speed difference front to rear.

Thanks Hartmut :)


Thanks Les, I assume that is why the US design favoured (what appears to be) a larger/stronger gear to connect and sacrifice the bearing. The only time you get the speed difference is spinning wheels, towing the vehicle, front wheels in the air, rear on the ground etc..

Both types say to not tow the vehicle like that though.

The bearing minimises wear on the shift fork. Greg
