It's the same job I did on my land by stretching the rilsan hose up to the hood
Let’s hope someone on this forum that has their Grenadier can clarify the situation
I suppose its a bit of a cost saving feature. The only time you really need to worry about this is if you jump off the highway and right into the river. Normally while 4 wheeling your axle oil wont get so hot that the gas contraction from the cold water is strong enough to draw gas through the seals- the overpressure vents are spring loaded, so it takes a few PSI (chime in if anyone knows the value, I've never seen it) for them to vent in the first place. In common use, they probably wont normally vent, the pressure just changes inside the axle up and down within some minor range. This isn't necessarily the case in the transmission and transfer case, however. Anyway, back to axles. So for the most part, even if you ford a creek in the course of normal off roading, you are aren't going to have a large enough pressure change to force water through the axle seals, which are spring loaded on the inside of the seal, and a pretty secure fit besides, making the vents not necessary. But the overpressure vents are installed for highway driving, because the change from sitting to 70MPH on the highway will definitely create enough pressure to need a vent, and you sure don't want it blowing out the axle seal to do it.Ok from reading that isn’t there a flaw in the Ineos design then,
vacuum created and then drawing water into the axle via the seals whilst wading. I dont suppose wading mode could mitigate that
Well Said (and I can relate)...thanks to the Alex Beras video this minor mystery is solved. The PTO2s with RAI have only these simple Diff Vents.
Not robust enough and too easy to disguise damage in the bellows. If you look at the reviews, most of them are for smaller axles, like side by sides and such.
What size hex key for those
I'm going to check the levels tomorrow, so I'll add that to the list.What size hex key for those
Can’t wait to get mine next week and get to familiarise myself with it as you are doingI'm going to check the levels tomorrow, so I'll add that to the list.
Thanks for that, I happen to have one in my garage. Any further recommendations on specific tools apart from the regular would be much appreciated
Actually, that hex key was ideal for the drain plug but not so good for the fill/level plug on the front diff. Access is hampered by the various huge tubular steel arms ~ I'm not sure whether a socket Allen key and a 6" extension bar would be easier or not. Ran out of time to find an ideal solution today.Thanks for that, I happen to have one in my garage. Any further recommendations on specific tools apart from the regular would be much appreciated
They won’t be. 800mm is basically the top of the tyre, so the breather will be below that
No, but if they are one way valves the methodology for them working means they don't need to be above the operational wading depth.
Do you know how they compensate for temperature / pressure changes
When temperature increases and internal pressure increases the spring allows the release of pressure. When you enter water the diff will cool and pressure drop and the cap will seal tight. I guess the question is what happens when after it heats up and vents air, then it cools and a vacuum forms how is that vacuum resolved. Possibly through axle seals which is ok if above water, but you don’t want water coming in through seals.
