    Camshaft Chainwheel is SOOOOO tight

    Gentlemen,
    I started my engine rebuild yesterday, and following the WorkShop's manual, the first task was to install the Camshaft into my nicely rebored 1953 block, but I was surprised at just how tight the fit was when I attempted to fit the Chainwheel, which the "book" requires to test the end float.
    As the Chain wheel is keyed to the Camshaft, I had expected it to be a firm but manageable fit.
    I found that it required a LOT of hammering to get it to slide on, so I feel something, may be the Cam end or the chain wheel centre, may be burred.
    Is it acceptable to try to smooth these out a little with Emery Tape, so it becomes a more manageable fit?
    I plan to remove the Chain wheel this morning, now that the end float is OK, and re-install when I do the timing.
    Having to pounding it into place just does not seem to be right, as I am sure it will damage the Cam shaft bearings unless I can find a better way of doing it.

    Any advice would greatly appreciated.
    regards
    Jeff

    hammering it on doesn't sound good. You will need to measure the fit and see what is occuring.
    It may have a burr on it or be out of round.
    Pictures will help if you can post them

    Try heating it in a warm oven before fitting. And use a bit of lubricant. It obviously fits eventually if you’ve had it on and off again.

    Are these the original cam & wheel or new replacements . If original how tight was it to get the wheel off in the 1st place , some times if the key is not sitting home properly & sitting too high in the grove in the cam. it can make it tight. If new parts you may find the cam is O/S or wheel bore is U/S , they could be made by different manufactures . You may need to take some accurate measurements of booth.

    Personally I'd be using a press rather than a hammer. Press the sprocket onto the camshaft then offer to the block for end-float.
