Re: MS440 Cylinder Screws

  Good Morning all,

  Loose, missing, cylinder screws are not at all uncommon.  Usually starts with right front.  Have seen this many times.

  Sometimes the threads are destroyed, sometimes not.  The PTO rear and flywheel front screws may be broken or damaged.   Check the crankcase screws also.

  Had a "Red Eye" come to me, "worn out, no impulse."  Two screws missing on PTO side, right front cylinder mount broken off, flywheel side screws backed part way out.  No impulse because cylinder was flopping around on crankcase.

  Not a bad idea to check these screws when doing maintenance.

  Take care, Larry.  HOS.

I don't understand why they get loose.  Is it because of the steel shim cyl gasket?  I've never seen a Husky get loose but I'm a relative newbie only about 10 yrs.  I will make it standard practice to check the screws from now on.  Thanks.
Shep
