Series 2 Free wheeling hubs. Potential daft question

Trench Rat · Aug 6, 2019

hi all

The other day I wanted to see if my FWH were jammed or not so turned them each way with the engine off just to free them up a bit. I put them back where they were when I found it. All the way anti clockwise.

Question. Before I set out today, do I need to do anything else? Like select 4wd low or high? Or can I just bugger off on my merry way?

Transmission things like this confuse the **** out of me and I don’t want to cause any damage.

Any help is much appreciated

Also which direction should I have them in?

Not a fan of them

What type are they.

You should be in 2WD on the road anyway. With FWH engaged, the front diff and prop will be turned by the wheels on the road but not connected to the engine unless you engage 4WD high or low. With FWH disengaged, the wheels are disconnected from the drivetrain and the front axle/prop won't rotate while driving. Supposedly this saves a bit of fuel but on a Landy with the aerodynamics of a mining shovel I doubt you'll see any difference. Probably going to take them off my 109 as they're one more thing to cause trouble.

Just drive it.

i leave mine engaged all the time, ready for use if needed (rarely) they say it keeps things moving and oiled ,unless you engaged 4x4 by pushing down on the yellow knob then you can jest drive on in 2 legger mode

Thanks for the attachments! I now know mine Selectro type!
All i know is, don't select 4WD when the hubs aren't engaged, but there's nothing to say you can't leave them engaged all the time of you wish.
So long as you engage them a few times a year you'll be fine, same goes with 4WD, it's good to keep the levers in working order too. I try and do a few yards in low just so i know it's all happy. In a straight line of course

Just make sure they are both set the same!

I have read on here that leaving the free wheeling hubs disengaged, but 4x4 engaged at the transfer box can cause damage to the hubs.

I also read that leaving only one hub engaged can destroy the front differential.

Something else I found out about the AVM hubs is that the rebuild kits are discontinued for the older types.

I removed the AVM hubs that were fitted when I bought the my Series 3. The selector plate seals were leaking oil and I could not find any source of replacement. I am now back to plain drive flanges with one less thing to worry about.

Sorry all it took so long to respond.

Yeah I have it in 2wd. Just coming up soon I’ll be going across a few fields and it’s potentially going to have rained so I’d just like to know the procedure for safely engaging 4wd either low or high concerning FWH. Back before I knew what I was doing or aware of them, I did engage and try to drive low with them either on or off. Then turned them. No damage was caused fortunately. It’s all good. I’d just like to be sure of myself and tick all the boxes.

Not too difficult to remove are they? I’m not sure I’ll really see much benefit in mileage as it doesn’t usually go much further than around the island.

A full turn clockwise on both should mean I’m cool to go 4x4 when needed? So far she’s been exclusively on road and over a few fields in 2wd

Thanks for the PDFs. I’ll give them a look over.
