What do I need to make and fit breathers?

No issues with Swarf getting into the diff while tapping? If not, I may be tempted....

I don't fancy changing all the diff oil as well.

What's the problem with changing the diff oil? If you have not done it recently it will probably be due.

Can you get a kit just for the diffs?

When I did mine I coated the tap in grease. Caught most if not all the swarf.

Done an oil changethis week and no issues!

Yup, the basic kit, which is the one I have is just for the diffs. Very easy to fit, even for a novice like me.

I didn't have any problems with the swarf, but I made sure I changed the oil afterwards.

It has been done recently. Maybe I'll do the whole lot in the spring.

Finished off my breathers today! Thanks to reading this and other recent threads on here about fitting breathers... it inspired me to have another look at my gearbox breather...



Lying on my back in the garage I could spot the breather poking out in the transmission tunnel... Strange, as I'd always read that getting to the gearbox breather was a real chore?



Closeup... there's just a little bit of rubber pipe on the breather tube and then a small plastic cap on it...



So I reached up and pulled the cap off, and used that as a reference to order a reducer - 8mm internal pipe to 6mm plastic tube to match what is supplied in Martin's / BigJimny's excellent breather kit...



The reducer fitted perfectly into the end of the existing breather rubber tube, and the tube supplied with Martin's / BigJimny's breather kit fitted in perfectly...



And the other end of the tube plugs into the manifold block I added to Martin's / BigJimny's breather kit (as my Rockwatt Rocklobster transfer box already had a 8mm elbow connected to it when I got it)

You may remember, the right hand 8mm black tube goes back to the transfer box, the 3 smaller 6mm tubes pointing down go to the front and rear axles, and now the gearbox breather, whilst the left one heads up to the snorkel's head -





And is neatly held to the genuine Safari snorkel with a couple of plastic P-Clips on the mounting bolts...

Breathers Complete!

As said above, I used Martin's / BigJimny's excellent breather kit, but added the manifold block as my Rockwatt Rocklobster box had an 8mm fitting already tapped into -



I've suggested to Martin that he could add this reducer / coupler to his kit, as it's a lot easier to just slip that into the existing breather rubber pipe?

Tapping the axles is extremely easy, easier than I thought it would be! -



Then the elbow connector just screws into the thread you've cut -





Breather is the right-hand blue tube, the other is the ARB's airline...

My diffs were already out for rear ARB airlocker / front LSD installations, so changing the oil was a necessity anyways...

It's probably wise to change your axle oils at the same time as fitting the breather tubes, particularly if you've already been offroading / greenlaning without "proper" breathers fitted...? :blink:
