Re: (ET) Mower deck motor

Could be the lower bearing. Alas, the 'drain' holes are not one-way, and water can get up into the motor from below (like hosing off grass from under the deck).
To get at the lower bearing, you need to pull the blade flange. The flange can be hard to pull off. One thing is that you need todo is insert a bolt into the end of shaft to pull against ( as I recall). Heat and cussing seem to help too (also as I recall).
After you pull the flange off, the armature can be removed from the top side. Be careful, especially on reinsertion, as the armature will get pulled, with great vigor, to the magnets. 

Keep track of any shims on the either end of the armature.

It appears to be below the magnets it does spin just not well. Also when I took the cap off the isulation on the wires was kind of melted off. Is that bad? I have high res pictures of it if your interested. Tom

    My guess is the brushes on that motor are frozen.  It happens to
    old motors FREQUENTLY.  Free them up and it will spin.  Where is
    the rubbing at?

    Hi,
        I'm trying to get my mower deck going and two of the three
    motors jumped right to life and leveled off with a nice hum. the
    third no so good, although spinning not near the RPM's of the
    other two.  Being a curious idiot I took it apart, the top bearing
    is in good shape there is some minor rust speckled though out the
    inside of the housing and the magnets are in tacked. There still
    seems to be some rubbing going on internally.  How much power do I
    apply to them for bench testing? Is there a schematic available
    for these?  Is there a lower bearing?  If so how do you get to
    it?  What is the proper gauge of the wire that is feeding the
    motor?  I'd appreciate any input, as these are antiques and I
    don't want to F* up any parts that can be fixed.  Thanks for the
    answers to my last posting (36v Charger) I'm learning everyday.
