Diff breathers

On a whim while under Gren. I loosened the diff breather on the rear diff housing and heard the "puff" as air / volatiles escaped. Not driven for 3 weeks/ 12, 500km.
Read the foregoing posts and went searching for a local supplier of diff breather kits with M10 x 1mm threads, 6mm push in fittings ... none of the usual pneumatic bits and pieces suppliers (eg.including Fittings Express) stocked them....solely 1/8" bsp!!

Finally discovered a local supplier who had the requisite parts in a kit which was significantly cheaper than trying to cobble a kit together from different suppliers!

I spoke with Russel. He was very interested in the Grenadier and readily offered to swap out the usual 1/8" bsp fittings for the M10 x 1mm when I explained the requirements. I'm assuming he'll add Ineos Grenadier to his offerings. He ships worldwide.
His pricing is excellent compared to ARB for example.
Whole lot was A$55 plus express postage at cost. So $71 Inc GST. Ordered yesterday, was in my suburban Brisbane P.O. Box by 0730 this morning!

@TheDocAUS : another option for the "local" list

The photo shows the complete kit with straight fittings and includes push in barb adapters to connect to a flexible hose from the transfer case and ZF transmission breathers if one is so inclined. Excellent quality. Right-angle diff. fittings are available but the collective wisdom in this thread is that the straight fitting is preferable. The standard aluminium bracket is shown. It is available in stainless steel and laser etched labelling for additional cost. see the website

Thanks for this @DenisM - perfect timing for me was just looking at their website yesterday !! Cheers

Marvelous work @DenisM
Based on the chatter here I was going to pull an axle breather out today and see what air followed it. We know the Carraro breathers are designed to hold a positive pressure but not at the expense of pinion seals. Based on Agile's video I think the seals aren't necessarily failing. They're a two-piece seal that appear to be struggling to hold back the housing pressure so are weeping.

Edit: APA have already put an Ineos specific kit in their shop. Direct link.

Looks like Air Parts Australia has added the INEOS kits, look here. A basic 4 Point diff breather (AUD75), a 4 point Pro version (AUD89) and a 6 point version (AUD85). The 4 point Pro uses an Black Anodised Aluminium Manifold, the other two kits use a stainless steel bracket.

The Basic Kit is more expensive than what DenisM paid, one reason is the kit has a slightly different selection of parts (eg 2 elbows).

Well done. I will add to the list over next few days.

I tried the M10 x1mm push-in fitting. I used a 14mm long socket to remove the OEM breather and a 12mm socket to screw in the APA component. Fits like a glove. Has an O ring, so firm finger tight plus a dab of thread sealant and it won't go anywhere...

What thread sealant did you use?

I use a Loxeal Engineering Adhesive # 58-11 ---it's an anaerobic methacrylate ester-based high pressure thread sealant (I think in the same category as the "Loctite" range). Approx. A$16 for 50ml at the local hardware (also available at Bunnings) is far more cost effective than the equivalent Loctite/Permatex products. I've used it as a thread locker and aux. fuel tank thread sealant for the brass breathers and outlets. It's guaranteed diesel /oil proof.

Well well. @DenisM is an influencer

Received my 4 way breather kit today from APA. 36 hours from order to delivery. Not bad.
I'll probably only use the 2x diff breathers initially. The factory transfer case and transmission breathers are already high up behind the engine according to a previous post.

Couldn't resist another set of adjustable tyre deflators at A$36.32. Nice kit with a storage pouch containing a set of 5 alloy valve caps. I like to set my deflators at the desired pressure and not adjust them again except to check the accuracy occasionally. It's good to have a set at around 26-28 psi for off-road/dirt and another set at 15-18psi for soft sand. Just screw on set A or set B according to the terrain. No messing around with adjustments on the side of the track (after I have found my glasses).

And this 52 piece grab kit of rubber cushioned stainless P clips was a bargain at A$25.00. Can never have enough of those in my workshop. 1/4” (6.4mm) to 3/4” (19mm).

So my diffs are leaking. I have pretty much only driven highways/surface roads. Only engaged the center diff for a brief off road ride around some land I have.

Dealer ordered new seals so will have those done soon. Thinking while he is under there just have him add a breather kit. Does that make sense? I’m semi handy and really dont have a set up yet to work on the truck myself. Also have no garage and since I moved it has snowed every weekend except for 1….

If you're in Canada and don't have a garage then I would let the dealer do it. At least until summer..

Fitted the front and rear differential breather pipes. Had a slight issue that the front push to fit cheap shite alloy sheared off in the diff at abt 2nm! Thank goodness it had an interior 5mm allen key fitting, as would have been very difficult drilling or stud removal exercise from the diff. The Arb fittings are better than those off the internet.

Hopefully the new pinion seals will not weep now.

Once the weather warms up will tidy up the rear differential breather pipes pipe a little. 3 degrees earlier and was very stiff.

Also now got the last of the Almont bash plates installed. The fuel tank one.
