If your serial number is somewhere between 7501 and 20,000
your motor is a 1924. If your flywheel says A-25 your motor
is a 1925 or 26. Serial number over 20,001.
Take off the prop and remove the cover on the gear case.
If your lucky you will find a brown lubricant without any
water and the gears in good condition. You want to clean out
the gear case as best you can. You will fill it with either John
Deere Corn Head Grease or Lubriplate 105 Assembly Grease
but waited till your ready to run the motor. You want to
remove the water pump and check the condition of the
pump piston. Also remove the 2 hex caps. These are check
valves. Inspect their condition. They need to be clean and
free to operate properly.
There are 3 screws holding on the rope sheave. These screws
have a thread that isn’t available today. Be careful with them
and don’t loose them. You will need to make a “Knocker to
remove the flywheel. Watch the video on how to use it.
If you don’t weld you can just jam 2 nuts together. These
usually only need the points cleaned to have the spark return.
Inspect the fuel system. Clean carb., gas tank, as necessary.
Be sure the fuel line is clear and the vent hole in the gas cap
isn’t plugged. If you have any questions, ask. Someone here
should be able to help you.
