    Hi Wallydog

    Seeing that you already have the flywheel off, to do the job, I would be making a puller out of bits and pieces, I wouldn't try heat in this case and nor would I hit it out.

    If it is too tight to wind out with an arrangement of threaded rod, nuts and spacers, trot yourself into a electronics store and get a pressure pack can of freeze spray, spray some inside of the bush, get it cold enough and it will just about side out.

    great stuff for freeze branding a number on a single cow in the dairy herd also.

    Cheers Arthur

    Hi Mick

    Thanks for your offer.

    If you could get us the measurements of the diameter of both the S3 and 2A shaft end's that sits in the bush, that would be very handy info to have written into the workshop and parts manual's.

    Cheers Arthur

    Arthur, i measured with vernier the small shaft inner diameter as 19.1mm, prob 19mm. (S3) The larger hole dimensions is 22mm long - 28mmOD - 23mm ID(2 and 2A)

    the outer diameter is the same on both flywheel spigots at 28mm.

    G'day Wal,
    On my S1, I turned up a drift on the lathe and set the flywheel on top of the anvil, with two 100 x 100mm pieces of timber supporting the flywheel as close as I could get them to the bush. Gentle tapping with a club hammer knocked the old bush out quite easily.

    I take Arthur's point about not hitting a cast-iron wheel but I don't think any damage would be done, as long as the blows were not fierce. My back-up plan was to use my friend's press if the hammer didn't work,

    Cheers Charlie

    spigot sizes

    The 19mm spigot is off a V8. I found one at CLR parts. It has the right dimensions. W

    Just a little hint when putting the bush back in.

    You don't want to have any grease in or near the bush as it will always migrate onto the friction plate by centrifugal forces.

    The best way to ensure lubrication of the bush is to get a tin can or similar and fill with engine oil till it just covers the bush. Then heat the tin over the stove for little while and then let the bush sit soaking in the oil till cool or best overnight. This will sinter the bush with the oil, then take the bush out of the oil, wipe off excess oil and let it sit for an hour or so to let any extra surface oil bleed out.

    Then you can insert the bush in the flywheel. The oil should assist insertion and will be more than sufficient to lubricate the pinion.

    For future reference- the easiest way I’ve found to get out the flywheel spigot in-situ is to find a rod or bolt that just slides into it. Next, pack it’s hole full of thick grease. Finally, place the bolt/drift aligned with the grease-filled hole and belt it with a club hammer. Hydraulic force drives it out.

    If you don't want to waste good grease, then wet toilet paper works just as well. That is how I did mine.
