    Hi guys
    I've got a 2ltr 1979 bay with worn inner bushes and inner torque arm bosses.
    Been able to find good 2nd hand torque arms but not bushes. Needle rollers are still available.
    Does anyone know if the inner suspension bush is still available and where. A part number would be handy too.
    I've searched every where I know but no luck.
    Failing that does any body know the exact dimensions of this sucker so as I can make it. I've made a tool to remove the bush but I know it will be slightly mangled and not measurable when it comes out.
    What does every body do in this situation? Surely this suspension system doesn't last forever?
    Sorry for all the questions and thanks in advance for any information.

    most people are oblivious to the worn bushes and the wear on the arm.
    and yes, most are worn to varying degree.
    As far as I know there are no replacements.
    There is a full nylon type replacement. Ian[tin bits has fitted some so hopefuly will post a link.
    my guess is some turned out of brass should do the trick ?

    Thanks for a reply, ordering bushes from cip1.
    There were part numbers on the bushes when I removed them that line up to the ones that cip1 have.
    I'll be ordering them today.
    The lower bushes were in pretty bad shape
    I'll try and post pics P1190416.jpg P1190418.jpg P1190419.jpg P1190420.jpg P1190422.jpg P1190423.jpg

    the wear is probably representative of about 25% of the sample ive seen . about 50% of that wear is another 25%. only got out about 25% that could be regarded as close to untouched.
    Like your puller.
    Was removal with it easy enough?

    I ended up removing all 4 bushes (top ones weren't too bad). The puller was a pusher I guess and the bearings came out easy but were pretty tight in there. I was worried that the plastic sleeve they were in might come out but it didn't. The bump stop snout held the beam off the floor level with the jig I've got it bolted to so there was plenty of clearance. Half a dozen wacks with a lump hammer and they were out. The centre support for the torsion bar limits the size of the long rod, I used 25mm brass rod I had and I don't think you could feed much larger through. Interestingly the bush is made of steel with about 0.5mm copper inlay and a Teflon coating over that. I think my forefathers knew that grease wasn't going to go through the bush properly (no spiral) to lubricate it. I also noticed that the 2nd hand replacement arms had witness marks that showed a much wider bush. Wonder is that an earlier version? Hardly any wear on the arms so might have been a better arrangement.
    Cheers

    Got the parts yesterday (very quick from cip1.
    The front end bits were pretty grotty so decided to spend the day cleaning them up.
    Going on hols for 2 weeks down far south coast and reassembling when I get back.
    Paint should have dried by then.

    Ok back from hols.
    I coated the inside of the tubes with Lanolin before I went on hols. There was hardly any rust but don't want any in the future.
    I don't think these beams like creek crossings (where they get submerged).
    Finished yesterday by coating the tubes with chassis grease using a bottle brush smothered in grease. (worked pretty good.

    I made some drivers for the bushes and needle bearings.
    Unfortunately the bearings don't butt up to stops so I had to build them into the drifts (took all day to make) so that they sit in the correct spot.
    Anyway they went in pretty easy

    Thanks Mark & Linder good to know for the future although I'm not sure I'll ever have to do a beam again.
    Not sure which Stockers (could only find an out door power equip place in Newie.

    Progress over the last couple of days.
    Firstly disaster. Cracked torsion leaves. It took a day of searching and 4 sets of springs to build up the 2 that I needed to fit the beam.

    Something interesting, the welded end had the most cracked leaves. Not sure wether because not allowing the outer leaves movement(sliding) in the torque arm (only the inner 3 leaves are held by the grub screw) or because that side is the one that ends up running off the shoulder of the road (pot holes).
    Anyway the welds had to be removed to inspect each leaf an I'm not re welding ( I think it's a mistake to weld in the first place and the end plugs are very thick)

    here's all the replaced parts. Cost more than I thought.

    Droolling over workshop. Your work shows us hackers how it should be done. I removed my arms to get the ball joints replaced on one side.The weld at the end of the torsion leaves was broken, so I welded it back up because I thought the leaves needed to be held together so the arms would go back on.
    cheers
