Hi all!
 I'm new to tractors.  Our 1.5 inch scale live steam railroad group had a 1955 Supper 55 donated to us for track and yard work.  Several of the members have  volunteered to make repairs and keep it running. 
   The tachometer is smashed and the drive cable is hanging loose with the lower coupling torn off and missing.  My question is, where on the tractor does the tach drive cable attach?  This is something that the shop manual doesn't appear to cover, and we cannot find it.
  The next question concerns the air filter; when the lower oil cup was removed it was full of crud and the inner cup was rusted off.  The filter mesh above the cup is in the same condition and I feel it needs to be replaced.  Is there a way to remove it, other than cutting the lower screen out?  As I said we're new to this and help will be greatly appreciated.
