    I'm trying to replace the camshaft bushing, aka the breaker shaft bearing...

    Any tips on doing this??

    Thanks a bunch!

    - oops:D::doh:thumbsup:

    edit...all of mine are roller bearing, but ive just been reading that some are bushed ? ...i wonder, if so, if you could drill them like the clutch pushrod bush

    - do you have a bush or a roller bearing in there...well, ive never had to do this, but i could imagine using a long thin brass drift to tap them out from behind, or a small bearing remover to pull them out :D

    - i doubt theyre long enough..go to a building centre or home depot or such and get a length of brass rod, thinner than the points/advance timing rod, cut say 150mm longer...you want to put a flat or slightly concave surface on the drift end

    - do you have the points and advance housings off yet...they can be somewhat problematic...

    Yeah I've got the housings and everything off, I even have the cam pulled out of the engine..

    When I use a drift to get them out, Do I go all the way through from the opposite end and just know the one bushing out? and then do the other side the same way?
    ...Kind of a dumb question maybe but i've never used a drift before

    I used a 12mm anchor bolt expanded inside and hit out from the other side.

    - yeah...but use a small hook first to make sure there is a lip on the inside you can use

    What you need is an internal bearing puller. You'll have to do some leg work though because they're not that easy to find. It's basically the same as the anchor bolt idea but a proper kit will come with a fitting that hooks on the inside edge of the bearing and a slide hammer that threads on to that. Good luck, I've been there!

    I just did mine last week, tried to use the blind hole bearing puller ( the type you use to remove spigot bearings in your cars flywheel etc..) & it was a bit to large.
    I ended up holding the cam in the vice with soft jaws & gently tapped in a screw extractor (easyout) & slowly spun them out while keeping the bight engaged on the easyout. Worked really well.
    I then used a shouldered drift to gently tap the new bushes back in.
    All in all it was a lot easier than doing the clutch pushrod bush.

    Cheers.:thumbsup:

    Why are you pulling them?

    Got a rephased cam from Mr Riggs with no bushings installed.
    Had the new bronze bushes to install but needed the old labyrinth bushs out of my old cam is all......:thumbsup:

    Ok, makes sence.

  17. Question, how hard do the new bushings go in? I have an '82 that I plan to go to a PAMCO on....I was able to pull the advance setup out of an old head (one with the labirinth bushings) and tried to pull the bushings out just to see if I could...kinda tried half hearted, but it seemed to install them in mine I'd have to put them in the freezer or something????

    Can the bushings be installed without pulling the cams?

    To extract old bushings, cut into them with a 1/8" NPT tap just far enough to grip, and pull them out. New bushings should install easily, no tighter than light tap fit; there's no need to remove the camshaft.

    When I installed mine I used a shouldered drift & pushed by hand - they nearly went all the way in, I then gave it the lightest tap with a small ball pein hammer to ensure they were seated correctly....you should not need to freeze them..:D
     
  20. Thanks grzld and hotdog, that will help.
