Avis Adjusters advice
Anyone out there fitted Avis adjusters? I have removed the outer needle bearings from the torsion tubes (and am going to use uerethane replacements)
but the inner metal bushes/plastic sleeves are still there as the Bentley manual states that the plastic sleeves which are used in conjunction with
the inner metal bushes cannot be replaced.. Will I damage the plastic sleeves/bushes when I heat the centre of the tubes to remove the locating dimple
and weld in the adjusters? (hope this makes sense)

No responses so I will re phrase my question. As I understand it, the torsion arms on the front beam run in needle bearings at the outer ends of the
torsion tubes and metal bushes with plastic sleeves about 125mm in from the ends. When welding adjusters into a front beam, do you need to use a heat
sink or similar to stop the plastic sleeves being damaged from the welding heat?
Also, has anyone managed to clean the grease from the torsion tubes to stop the grease catching fire when welding on the Avis adjusters and if so how?

I have never removed the inner bushes when doing the adjusters.
I always clean out the grease about 150mm from where you plan to weld,
but the reality is you should never get THAT much heat into the beam at the time of welding anyhow.
Not sure about ball joint, but on link pin the inner bushes re not steel cased plastic,
but a fiber/bakelite style of material.
Either way, they are a long way from where you will be welding.
If worried wrap a wet towel around the area,(where the bushes are), while welding the adjusters.

I have done a few Avis style adjusters (Indian Automotive supplied) onto Bay bus beams, and I slam the centre holder with a piece of steam pipe as per
their instructions. The dimples pop with no heat. Then after cutting the slot for the adjuster grub screw, I use a massive pin punch to hit the rest
of the dimple out from the inside. This allows the centre holder to rotate fairly easily.
I don't clan any grease out to weld. The industrial 250A MIG I use on very high amps allows a quicker weld, and there is a bit of smoke, but no
fire.

Thanks heaps guys. It is a BJ type 1 beam. I will give it a try without heating and see how I go. This forum is cool! (pun intended)
