    stab removal

    As I watched m-487 being de-winged for carting away of remnants..

    Noticed when it came to Stab removal, that the 2 bolts holding 'er on, were
    quite seized & required quite a bit of 'farmer mech' ..to remove..

    As I understand it, the 2 bolts that hold the stab on, had bushings & doubt
    that they were ever lubed, after factory install !? ..(~33 years)

    Anybody know about wether these 2 bolts are required to be lubed ..at some
    point?

    thx,

    jon

    stab removal

    Funny you should mention this.. was down with the plane during annual today
    and the A&P showed me how when he lifts up on the stab from the outside end
    he could feel a little bit of play. He then showed me the bolts holding it
    on and said they eventually need to be replaced. He said he'd like to
    change them by next annual.

    stab removal

    I use ACF 50 on the stab bolts at the 25 hr lube interval or when ever I walk by with the ACF-50. I also lube the trim hinge. I replaced the timkin bearings in my stab last year. It isn't a difficult job. I discovered that minor slop translates into shot bearings. I had a little slop and when I removed the bearing, I thought there was also a space/shim. It turned out to be part of the bearing race. I'm sure this is an over looked item on many Musketeers. I recommend changing the bearings and bolts when slop is present. Also, the manual states AN bolts can be used. The original bolts are high strength, close tolerance that add, from what I remember, approx twice the strength of the AN bolt. I ordered mine from Genuine Aircraft hardware and they were 8 bucks each. The bolts use a nylock nut as a cotter pin can't be installed. There are shim washers that can be purchased to take out all the play. These need to be special ordered as the light AN washer called out for in the service manual is too thick to work. I believe there was about .010 play and the an washers were .020 - 0.22.
