I still need to extend my diff breathers on the 2.7.
I see on the 4x4com site they talk about a 1/8 BSP fitting you can use.
What did you guys use.

Posted: **Wed Feb 02, 2011 1:54 pm**

George Check the shop, I think Cassie sells Kits for the diffs?

Good luck

George, Zane is correct. I sell these kits. They use a 1/8 BSP Quick Connect Elbow on one side and a quick connect with brass filter on the other.

Cas, kan jy vir die D4D ook kry?

Posted: **Wed Feb 02, 2011 2:35 pm**

Cassie ek soek 'n stel

Posted: **Wed Feb 02, 2011 2:36 pm**

Sover ek weet is hulle almal dieselfde size. Daai wat ek het pas op die SFA en IFS. Net nie seker of die op die Vigo ook pas nie maar kan nie dink dat hulle daai fitting size sou verander het nie

Posted: **Wed Feb 02, 2011 2:39 pm**

waar is die shop? Cassie wat kos my SFA se kit? Voor en agter?

Posted: **Wed Feb 02, 2011 2:44 pm**

Vir 'n SFA het jy twee sets nodig en hulle prys R180 each

Posted: **Wed Feb 02, 2011 2:49 pm**

Vir die Vigo het ek ook seker 2 stelle nodig? :wth:
Sal jy vir my die "shop" se bank details PM asb?

Okay... so smaak vir my die IFS het ook twee stelle nodig want die differential is mos nie deel van die ratkas nie. Hy is net bietjie beter weg gesteek.

But I've read a lot (on this forum) that these breather are very important if the diffs get in water.

Hulle is baie belangrik. Jy behoort fine te wees as die water nooit hoër as die helfde van jou wiel was nie. Die ander manier om dit te minimaliseer is om baie stadig in die water in te ry. Die probleem is wanneer die diff warm is en jy ry in die water in dan koel hy skielik af en suig dan lug. So as jy stadig gery het en jou diff het klaar af gekoel was die druk binne en buite die diff dieselfde gewees en sou die water nie sommer in loop nie.

Maar dit is maar altyd beter om die breather te skyf want R180 versus R4000 na R5000 ... no brainer

Posted: **Wed Feb 02, 2011 3:35 pm**

Cassie

So for the IFS (2.7) do you need 2 sets or just one? Where do I place my order ?

Posted: **Wed Feb 02, 2011 3:39 pm**

Cassie jy maak die ouens deurmekaar............... :roll: :roll: :roll:

1 Set per vehicle

Okay lets clarify.... a set is made up of 1 connector to connect to the diff and one connector to connect with filter on the other end of the pipe. The set includes cable ties, cable tie shoes, and binding spur to protect the tube. So in general you will need two sets per vehicle.

I have some in stock (not sure of the qty). I can get some reasonably quick if you want more. So if you are interested place your name here with the qty you would like.

Baie waar, maar die standaard breather het 'n proppie wat kan op & af beweeg (dis nou op SFA, nie seker oor ander), so teoreties hoort die doppie vas te suig as die diff te vinnig afkoel en dus water uit te hou.
Natuurlik is voorkomende matreels beter.

Stef, that's the intention of that little valve, but they get dirty and don't seal properly. Then if it does seal as it should and your shaft seals (pinion and half shafts) are weak, it will suck water in there if the vacuum created is at all significant. I would rather fit high level breathers (to bonnet height against the firewall) with fuel filters on the end for 'free flow' of air. Just a thought.

Posted: **Tue Feb 08, 2011 7:44 am**

Morning Guys

I extended the breathers the other day on my SFA

Went to the local hardware and got an adaptor ( I think a 1/8" ) that fitted into the diff breather hole and another adaptor (I think 3/8") that had a 10mm tube on the one end. Then went to the local spares shop and bought some 10mm rubber hose.

The adaptor fitted perfectly and I just clamped the hose onto the 10mm tube adaptor and to the original breather on the other end of the hose.

The front I ran up to next to the brake booster and the rear I ran up to where the load valve sits. The rear one I did a couple of turns in the pipe and angled the hose downwards so as not to let water sit in the pipe.

Total cost was;
adaptors = 2 x R17
10mm tube adaptor = 2 x R12
3m 10mm hose = R54
hose clamps = had at home
labour to do job = 3 beers

I hear you M8...Fortunately the diffs were rather "cold" during the crossings I've done and I checked the valves

Like I said prevention is better, so the plan is to check the diff oil for water before even driving it again and to fit the extended breathers just to be safe

Currently trying to source 1/8 BSP nipples for the job (money is tight this month

)

You could also try the suppliers of LPG and LPG equipment. AFAIK they should have that swage nipple.

Posted: **Tue Feb 08, 2011 8:36 am**

You can also buy the parts from Toyota.

Breather Plug (part #90930-03136)
Union fitting (part #90404-51319)

And some fuel hose and clamps and Bob's your uncle

Posted: **Tue Feb 08, 2011 12:39 pm**

Tx Cassie

Haven't searched too far & wide yet, had the flu for the last week or so, put a much higher premium on sleep. Thought I'd try the pneumatic places first, I really like those connectors where you just stick the hose in & tighten the nut, just looks cooler than clamps

I see RS compomenents also have some @ R20 for packet of 5, but the 1/8 sizes are mostly quick couples it seems, will have to do the travelling bit.

Hi Shaun

The bakkie has gone in for bearing and seal kit on the front diff, so unfortunately it's not with me.

I'm getting it back towards the end of the week and will take pics for you then.

Posted: **Tue Feb 08, 2011 2:46 pm**

Why didn't you attempt to do the seals yourself. There are some nice manuals on how to do it. How much did they charge you?

Posted: **Tue Feb 08, 2011 3:59 pm**

Hi Mark

Did think about it, but time is a problem and I wasn't too comfortable doing the inner oil seal behind the pivot knuckle ( whatever it's called ). Normal wheel bearings and seals I would've done.

Louis from 4x4 MegaWorld is doing it and charging me R 2100 incl parts. He is also doing a few other bits and pieces, I felt that he was more knowledgable than me and folks on the forum only seem to have had good service from him.

Couldn't find the breather plug from the stealers, no stock....

Found a few pneumatic places that could supply, hopefully I'll make it time this afternoon to check one of them out that actually has stock; fittings tubing etc.

Is there anyone that still needs breathers? Maybe I could sommer buy enough for a few sets...

Posted: **Fri Mar 04, 2011 2:30 pm**

I need one for the front.

Posted: **Tue Mar 08, 2011 10:55 pm**

Managed to swing by the place on my way back to Pta 2day..

Bought the last 8mm one he had in stock (so much for "i have stock"), can get more if needed. Unless of course you prefer 10mm tubing (outer dia.); there is stock of the 10mm fittings (bit bulky though, 1/8th BSP thread with this huge brass head). Tubing a bit expensive @ R10/m, want to see what hoses Autozone have & if it will work with the push on fitting, but that will probably be around R6 - R7 per metre anyway

Posted: **Tue Mar 08, 2011 11:15 pm**

Stef, this is a standard size nipple (8mm) used in the LPG appliance field. Those guys should have stock, give them a try.

Mud Dog wrote:Stef, this is a standard size nipple (8mm) used in the LPG appliance field. Those guys should have stock, give them a try.

Been to a few in the area, but no one had in a 1/8" & asking for BSP makes them frown somewhat

Besides, how purdy is this?

Over engineering I suppose, but just looks so much more like it was factory fitted...

Posted: **Wed Mar 09, 2011 7:19 am**

will they be getting more stock?

Posted: **Wed Mar 09, 2011 9:30 am**

Asked the same question; oke doesn't seem keen to keep large stock. But if I need some he'll arrange to get stock in.

Bit of a schlep but his prices on fittings are extremely good compared to other suppliers, it's the pneumatic tubing that's expensive...everywhere.

I'm looking to put some kits together if there is a demand, possibly around R300 for a full SFA kit (both diffs), cheaper if I could get alternative tubing and buy fittings in bulk. Will start a new thread once I do

Posted: **Wed Mar 09, 2011 7:26 pm**

I've still got to the same thing to this 'new' bakkie .... had to drain both diffs and replace the oil because both were contaminated with water. But I prefer, and will use a swage nipple fitting so that I am no tied down to pneumatic tubing. The ordinary rubber fuel hose is more flexible (and cheaper).

Posted: **Wed Mar 09, 2011 10:56 pm**

Different strokes for different folks!

Had a look at the GAV range of fittings 2day at Builders WH...8mm nipple = R18 and a reducer to 1/8" = R24 thus a total of R42, times 2 plus clamps...the pneumatic ones are normally around R30 each.

Fuel hose around R7 per meter vs R10/m for pneumatic tubing, R13-R16 at some other places,at worst a R63 difference (assuming 7m of tubing), R35 if one takes the saving of the fittings & clamps into account...
defintely pneumatic for me... :wink2:

Posted: **Wed Mar 09, 2011 11:23 pm**

And what are you doing with the ends of your breather pipes so that they don't get dirt / water in there?

What I did before was to fit a fuel filter to each breather end, bending the pipe so that the filter faces down and not up. If you do get water up to that level for some crazy reason, it won't enter the pipes .... at worst just a few drops will get into the filter but will be expelled again next time there is air expansion in the system (when the diffs warm up again). Works perfectly without any need for maintenance of any kind ... ever. Not sure if you can push pneumatic tubing over the nipple of a fuel filter, or if you can get a sharp enough bend to look neat without using elbow joints.

Posted: **Thu Mar 10, 2011 8:19 am**

1/8 BSP is a fairly common hydraulic thread.

If you guys are really wanting to go all the way, you may also try the racing style fittings (anodized alluminium).

Aeroquip agent in Pta (Hydraquip) and Germiston (Rudmans Hydraulic) used to stock them.

Posted: **Thu Mar 10, 2011 8:29 am**

Still working on that

...want to use a mountable Y-piece/ T-piece to accept the tubes from the diffs & fit a filter on the other end.
The proper brass filter is around R30 and it's plastic counterpart R10-R15 depending on the size, neither one waterproof of course. Pneumatic tube won't fit over the fuel filter but with 8mm outer dia. one can join the two with a piece of fuel hose, should you really want to.

Whether your filter points up/down is not as critical as the highest point of your line as water will push up the tube to match the level outside, but even that could be overcome by just coiling the tube twice or so close to the diff IMO.

I suppose one could extend the line after the T and push the pneumatic filter (small in Dia) up the snorkel, but a bit of an overkill I think...I'm just going to mount as far up the firewall as possible.

Right on Rikus, haven't tried Aeroquip yet...

Posted: **Thu Mar 10, 2011 8:49 am**

I never tested it at the time, but I reckon that by the time the water reaches the filters the diff will have cooled down considerably and any suction at the filter from contracting air volume will be minimal. The point of mounting the filter facing down is that the filter would have to fill up first before water enters the pipe. This allows for a larger volume of water to be taken up without any problems. Even external water pressure won't push up very far if the filters become submerged since there will be back pressure from the air volume, and of course the external pressure would only be slight.

Posted: **Thu Mar 10, 2011 10:28 am**

My thoughts exactly :wink2: ...and without any other vent in the line it would be really difficult for water to enter anyway, especially on a small dia. tube
Only benefit of the upside down fuel filter would be the added volume then...

So I guess 6 of one and half a dozen of the other, fuel filter volume or a few extra coils in the tube

really a matter of preference?

Posted: **Thu Mar 10, 2011 11:08 am**

You're stubborn like me!

So I guess 6 of one and half a dozen of the other, fuel filter volume or a few extra coils in the tube really a matter of preference?

I don't necessarily think so, Stef ..... lets for argument's sake say that you get into deep water quickly and the breather ends are submerged before the diff has time to cool down sufficiently and it manages to suck up a full filter volume. How many coils of narrow diameter tubing would be required to make up the same volume so as to avoid water getting to the point that it starts running back down the tubes to the diffs? Then when the diff heats up again, with a filter facing down all the water will be dispelled, whereas with coils how much stays behind in the troughs of the coils? ..... of the water that stays behind, how much will get into the pipe to the diffs with normal expansion and contraction from daily use afterwards.

It's a small issue because how often will you ever go that deep, if ever, but I feel that if you're going that far with the installation you might as well get the best benefit.

On 6mm inner dia vs 50mm about 69,4mm for every mm of the filter's length

(I calculated) but how much volume does one need?

That's a good question... but I guess with the push on connectors & transparent tube it is a 5min job to inspect & drain the water.
