Hi, I am rebuilding a Metro 1275 A+ engine for my Studio 2. I have completely stripped it down apart from the cam bearings in the haynes manual it says that a special tool is needed to remove them. Do I need this special tool? can I do it anyway? do the bearings need replacing regulary?

Thanks in advance.

You need the special tool, and will need it to fit them too. Once fitted, they will have to be reamed to make sure they all line up so the cam doesnt bind, etc. If I were you I would get your local engineers to do the whole lot for you. Cam bearing dont realy wear out that much, and they are quite pricey to replaice too. The best way to tell if they are worn is to look at the condition of the face of each one, if it is badly scored of a goldy colour then they are no good, if they are still grey and look ok, then leave them alone.

As Bluemini said, look at the condition of the bearings to determine if they need replacing. Over here it cost me about $30 to have the new bearings installed (I think that's currently around 15 GBP). Paying a shop to do this for you is a wise and economical investment compared to trying to do it yourself. If you are planning on having the block hot-tanked (hot caustic washed) to clean it plan on removing the cam bearings, freeze plugs, and oil gallery plugs.

Thanks for your help I think i'll leave them as they are only grey couloured at the moment. All other bearings will be replaced mind you.

Hit them with a bloody great hammer stevo, or molegrips and wd40

I always get them changed. They don't cost much, 'nor does fitting them. The machine shop may as well do it while they're working on your block and removing them is the only way to get all your oilways properly clean. But each to his own.

I'm with Dan on this one, if you've gone to the bother of stripping everything then don't stop at the last hurdle, visual examination is a guideline only.

Get an enginnering shop to deal with it.
