    I'm replacing the timing belt for the 90k service. Whats the recommendation
    on replacing the shaft seals? Are they pretty easy to pull and replace once
    the gears are off?

    I've had two timing belts replaced on my old 94 Accord, and I never had
    the seals replaced. You should definitely replace the water pump though.

    Never had a problem with the camshaft or crankshaft seals, but there was a
    recall to install retainers on the balancer shaft seals. They are known to
    pop out and all your oil goes out with it if it happens. If you haven't had
    the recall performed, now would be a good time to get the retainers and
    install them. You also want to replace the balancer belt while you are in
    there and the tensioner probably needs at least a new spring.

    My 91 Civic is at 153k. I am in the process of replacing the front crank seal
    (a.k.a. front oil pump seal), as many have recommended as part of a timing belt
    job. The seal is coming out in tiny pieces. I'm tearing it up with an exacto
    knife, a small screwdriver, and pliers, trying to spare damage to the journal.
    I'm now considering removing the oil pump to do this right.

    This seal seems practically hardened into place. Maybe it's the original and
    this is why this is why it's such a bear. Will google to say if there are
    suggestions on this.

    Breaking the crankshaft pulley bolt free last week has paid off, anyway. Today
    when I went to remove it, it came off very easily, with I estimate no more than
    150 ft-lbs. of torque.

    I went through the same problem with the stuck bolt. I found friendly
    mechanic with an impact wrench it couldn't say no to. Funny how you run into
    different opinions. One block up from this guy was a mechanic who swore you
    had to heat it up to 700F to break the loctite loose and that you should
    always replace the cam and crank seals.

    The next guy sais there is no loctite and only replace the seals if they are

    Oh well!

    they are easy to replace, just remove the cam gear. I would replace the cam
    seal, balancer shaft seal, and front seal, with oem seals of course. be sure
    to install the new seals correctly. we do this on every timing belt/water
    pump service we perform at the Honda dealership I work at. inspect the
    tensioner and balancer belt and replace if necessary.

    Well-done. Here's to creative problem-solving. :)

    Should you decide to replace the seals, after thinking about it overnight I
    decided to try a corkscrew and a can opener (the kind on a scout knife). They
    worked great. The seal do pop right out, once one has a hook-like tool to get a
    good grip and allow a good several tugs. See my other post on this under
    "Camshaft Removal Question."

    snip amazing and amusing tale from "The Darkside" of Honda repairs. ;-)

    how about just remove the balancer shaft. No seal, no belt, less
    friction, less weight, and one less GM/FORD-school part in the engine sounds

    sure... there are two balance shafts. one in the front of the block and one
    in the back. they spin in opposite directions. removing them would require
    you to remove the engine from the car. you would then have a large hole in
    the block where the front shaft and seal used to be creating a huge oil
    leak. lastly, the motor would probably shake itself to pieces.

    the clueless helping the clueless. go figure...

    1) I don't take kindly to being referred to as clueless simply because I'm
    asking for advice on a particular maintenance task.

    2) They actually make kits for blanking off the balance shaft access after
    removing the shafts. Some gear heads want a few more HP and don't mind a
    little rock-n-roll.

    From what I know the balance shafts are there to remove a second order
    vibration resulting from the variation of piston harmonics between TDC and
    BDC. Its a nicety, but removing them wouldn't necessarily result in the
    engine shaking itself apart.

    perhaps but the other posters recommendation that the shafts be removed
    which requires pulling the engine vs installing a simple seal retainer while
    doing a timing belt can hardly be considered good advice.

    I agree, unless you're into engine-pulling kind of work. Some people are.
    I just don't like balance shafts at all. Wasting gas to sling dead weight
    around to make up for a little vibration just does not make sense. Then ad
    the fact that it increases the necessity and cost of repair and maintenance
    and it becomes a terrible idea. You can passively damp vibration at the
    mounts with no increase in maintenance.
