Thread: R380 Grumbles

I have a good used Defender R380 box here in North Sydney.

Case needs a lug welding back on and it may need a new shaft as its been out o a car for a while. But it's a good box and here if you need one quick.

How many K's are on the box and what oil are you running?. Do the Defender's have the oil cooler like the Disco?. May be some of the problem that the box is running too hot...?

I had a look at your web page www.goingbush.com
Awesome work guys and it has a great guide to TD5 defenders. As well as some cool old defenders.

It says on there that he has an oil cooler for the gearbox. And larger fins on the transfer case.

Wish I found the guide on the TD5 defender earlier its a cracka.

Don I cant answer your question but if you are running 2.5 litres of Moreys in the R380 this may not be good.
Years ago we tried to run 100% Moreys in Unimog Portals and found that you couldnt go above 80% or they would overheat.
Might be good to seek Ricks advice on that.
Sounds like its layshaft bearings if its doing it in gears 1-3 although I would of thought your box would have done the support bearings on 5th gear,
I saw a couple of your onboard camera videos and was wondering how long the R380 would last.

Just clocked over 186,000 km , I've always used Castrol Syntrans in it.

Its got a aftermarket oil cooler & runs fairly cool.

Thanks Duane ... I think, its only got 250ml Moreys, the rest is Syntrans,
its getting louder , Ive never worried about the weak 5th gear 'wifes tails" as mine has always been tight as a drum & as quiet as a mouse, I'm very suprised, ( disillusioned ?) it had gone downhill without notice, I changed the oil only 1500klm ago and it was clean after 10,000km .

Thanks Jon, Much appreciated, just hope I can make it back to Sydney, without a big bang, will drop you a pm if the situation gets dire

Don I have a spare but am probably a bit far away from you
I am wondering if a roamerdrive and running in 4th gear is the answer
That said I know my TD5 can easily squeel the tyres when I have one of Jose's tunes on it and the roamerdrive wont deal with the layshaft bearings

Goingbush.
Sounds to me that you have done your best to look after the box. Hope it is something simple mate. Towing my 23ft van I'm wondering when mine will scream ENOUGH!!!!. I'm running Syntrans as well.
