Is this hub standard

[marsonearth]

Hi
The following hub is off my series 2a

Which manual would have this hub in it??

How do i get it off, to replace the leaking oil seal??

Thanks for your help

Steve

Id say for starters undo all the screws and all will be revealed behind the front cover;)

No hub is standard, and I am not familiar with that one, although I have seen them. But like Rangieman I would guess that removing the screws will allow the operating knob to come off, revealing the nut on the end of the driving axle, which can then be removed. Carefully note where everything goes as you pull it off, and in particular watch for little bits that fall out - note where they came from. I suspect it is similar to the Warn hubs I have, with a collection of floating drive pins moved in and out by a multistart thread on the operating lever.

Lots of digital pics.

And then when you're done you can post them up here as a tutorial for the next fella.

:D

AVM i'm familiar with, but that is an earlier version than I have seen before. A few places online have install manuals for AVM hubs, but they usuall yave bolts with allen keys, not screws.

I have some AVM hubs off my S1 at home, will take photos tonight (or at the weekend).
Haven't got 'Warn' on them but may be the same.....

They look identical to the ones that were on my Series III. They never gave any trouble.

As others have said, just undo the screws to get access to the nut. It is a fair way in.

I don't remember anything complicated about the job.

The ones on my series 3 are a bit different, but not much. internals are probably teh same, and easy to rteplace the seal depending on what is leaking.

I just pulled a pair of them off of fozzy... (see his thread for more info + pics of the after math)

they are sealed with a pair of paper gaskets and require you to run grease in the actual freewheeling unit...

there is a seal under the "switch" but since I didnt need to remove that bit to get rid of the free wheelers I didnt look at pulling it apart..


dobbos old rover is now the most fuel effecient landrover going with 4 free wheeling hubs......

Checked mine and they do have 'Warn' on them (under all the paint).
One of mine is badly rusted, in fact one of the springs has rusted away. Took some photo's but didn't remove the selector because it looks like you need to pull out a guide pin which is an interference fit.

As Blknight said, paper gaskets and a seal around the switch/selector. Looks like they run in grease so if you have oil leaking out then maybe it's the felt/rubber 'seal' that fits on the driveshaft.

Thanks to all for the great info, I now have a weekend project!
The oil is leaking into the brake drum?

[JDNSW]

I presume you mean "oil is leaking INTO the brake drum". This will be the seal on the inside of the hub.

As you have identified, the first step is to remove the free wheel hub. This gives access to the bearing adjusting nut and lock nut, which can then be removed. followed by the whole hub.

You will need a hub nut spanner, the seal and a replacement lock washer for the wheel bearing nut. Check the wheel bearings while you are at it, andreplace as necessary.

then the oil is not leaking from the freewheeler its leaking from the hub seal...

to start..

remove the 6 screws and extract the selector(paper gasket here)
delve in and remove the locking pin (a bit fiddly i used 45 degree offset needle nozed pliers)
remove the axle bolt (watch for the spacer shim that might come with it)
remove the 6 bolts that mate the flange to the hub(paper gasket and again watch for the spacer)
using a small pry bar lever up the locking washer from the outer 52mm hub bearing nut and remove that
remove the locking washer, beat it flat or discard it for a new one
remove the inner 52mm hub bearing nut
grab the wheel and pull (watch for the outer bearing and thrust plate)
lay the wheel down so the brake drum faces up
you should see a claged out bit of black rubber in the middle of the hub...

more than likely that will be the offender, rip it out and reseat a new one...

reverse the above to put it back together paying attention to the correct setting of the bearing nuts.

Thats been covered previously on site but if you cant find it let me know and we can cover it again.

According to ARB's catalouge they do an AVM hub servicing kit.

Thanks for all the great information
Im' only just getting around to doing this job (Work before pleasure)

However I'm still having trouble with it

I have highlighted the stage I am up to in red.

When I try to loosen the nut on the end of the axle: the axle turns,
making it impossible to remove.

Is there a way to lock the axle or diff??
I have put the vehicle in 4wd and the front drive shaft is locked.

Or am I missing the obvious.

Thanks

Engage the fwh on the opposite wheel, then pull the red gear lever back into low range 4x4. This will stop the axle turning while you're trying to undo it and, later, do it up.

Hand brake on

four wheel drive (either high or low, doesn't matter.

Lock the opposite front hub

Prevent opposite wheel from turning - either wheel on ground or lock brake with the adjuster if you have the wheel off or jacked up.


For the second one, after you have removed one hub, lock the axle by holding it with vice grips on the spline (if you are fussy, protect the jaws with suitable padding).

I just used a rattle gun...

[UncleHo]

G'day Folks :)

Not a lot of people have a rattle gun as part of their tool kit ;)

But as you have been advised, lock the opposite wheel into 4 wheel drive before trying to remove/disassemble the unit, the most fiddly bit is removing the split pin that holds the castleated nut on the end of the axle,(replace this split pin with a new one)the freewheel hub can be removed by undoing the 6 small screws, (with hub in 2 wheel drive location)then undo axle nut,then undo the drive flange studs, (check that these studs are not stretched, as they often are,stud threads have a waist in them) with the hub studs removed and the axle nut removed,a light tap will remove freewheel unit, you can then service the wheel hub as per the manual, replace with new axle hub nut lock washer, set bearing freeplay at .001-.003 thou inch.

If you have no access to AVM hub end gasket, one can be hand made from gasket paper available from REPCO, 1/32 nd will do.
