Heavy duty drive flange

[skoller]

I recently purchased 2 new Terrafirma drive flanges at the LR expo and I am about to fit them but I am not sure about the o ring seal. I have fitted the nut onto the flange and tightened it onto the o ring but it just squeezes out. Do you tighten it up the nut or tighten it just enough to compress the 0 ring a bit and use a bit of locktight on the nut to hold it.
Thanks for any help with this.

Just enough to compress it with thread locker. Pat

Forgot to add,put a blob of grease in the cap to lube the splines. Pat

I threw the o ring away, added sealant to flange face, then put nut on tight. Been working fine for over 2 years. They still come off, just put on new goop each time.

Sounds like a bad design. There should be a place machined in the cap for the o-ring to be held so that the cap can be fully tightened.

I think its a bad design also not that well thought out. What are the other brands like.

[Red90]

The only others I've looked at are Ashcroft and Maxidrive, both which seal properly.

I've fitted these and yeah they are poorly designed I did the same as micksta and just use sealant and ditched the oring

Just put Ashcroft's on mine. Very nice! There is a spot for the o-ring; they seal nicely.

If I was still working I could get the machinists to machine a groove in the flange to accept an o ring and all would probably be ok. Should have went with quality gear.

Whats the price difference betwwent the ashcroft ones and terrafirma? I think for the price terrafirma are ok but just use sealant almost looks like the whole o ring was an after thought to be the same as the competition. I've done some good amount of wading in mine and checked a couple of time and nothing is getting in still nice clean grease from when I packed them.

The originals were letting my diff oil turn into a milkshake with the poxy rubber cap acting like a diff breather or straw depending how you look at it let alone the masses or back lash

Ashcroft's are spendy... £90.00. TF from paddocks £25.50 (exc.VAT)
£30.60 (inc.VAT).

You could buy the TFs, some sealant, and a few at the pub for the Ashcroft's. But damn, when I put the Ashcroft's on, my 110 felt happier. And they look sexy. hahaha

It also solved the majority of slop in my drivetrain. I put 'em on with the paper gaskets, and tightened them without any sealant. No leaks.

I bought some hytuff engineering ones (took over from Maxidrive) from Rangie Spares for $140 each. Best of all is that they are Australian! No waiting to get parts from UK!

On the Ashcroft and the Maxxi, does the o ring sit in a groove on the flange or in the cap.

For both ashcroft and maxidrive O ring is in the cap

When I fitted new M/drive flanges the other day there is no way the o ring would seat, kept squeezing out. Had a look & there isn't a recess for it??? So the o/r ended up in the "odd o/r tin" & I sealed the thread with good gasket type silicon & tightened the nut "tight" so far all good

My maxi flanges have no oring just some sealer on the threads boring old black max on the thread will seal it up fine. I think the oring is on others is just to give people the warm and fuzzies

I'll post a photo of the Ashcroft with the cap off soon.

Sorry, it's started snowing... Had to clear the garage. And the pic didn't upload. Will post later today from my laptop.

Here ya go... you can see the lip in the cap for the o-ring.
