Thread: D2 axle breather coupling

I believe they are a std style.

I had a **** load of water in the rear diff and suspect the coupling isn't watertight.
I'll probably run a new breather line, too.
Had some in the front, so will swap it out too.

Not sure if the same but, had a blocked breather on the front of my D1, replaced the 1/4” nylon and banjo fitting with a 1/8” BSPT push in elbow to 6mm nylon hose. That’s what I had lying around at the time.

They are a fairly standard airline fitting.
The standard ones on my Defender were zinc plated steel and rusted internally & blocked.
As I work in the pneumatics industry I fitted nickel plated brass 1/8" BSP to 6mm swivel elbows, problem solved.

Deefers (and I suspect the D1 & RRC) are banjo fittings but the D2 uses a plastic push fitting into the axle tube.

I'll go for a crawl and see if I can remove it

When I advertised fittings & tubing on the forum years back someone came round with a Defender that had some odd fittings in the axle. From memory 4mm OD tube rather than 6mm. It was raining at the time so I didn't investigate any further.

The original on my '95 Defender was a banjo fitting which I tend not to use in pneumatic applications because they restrict the flow too much, hence fitting a swivel elbow.

You can buy the push fit collet mechanisms to press fit into your own product, these require some form tooling to machine the port to house them. I wonder if LR went in that direction and pressed the collet mechanism directly into the axle.....

At worst (did this on my D1)...

Remove original, drill / tap housing, fit elbow with press fitting.

On the D1 I ran 2 T pieces also, and drilled and tapped each swivel housing and fitted breathers in them as well.

Yep, I could end up doing that yet.

I'd say so as the collet is directly into the axle tube
