What is the shaft size on a Briggs and stratton 28m707 motor?
Unless the type # is off the wall strange, it has a 1" diameter shaft, 1/4" keyway, the end is tapped to thread size 7/16 - 20, and length from mount to tip is 3 and 5/32".
What is the torque sequence for a 18hp single cylinder Briggs and stratton engine horazontal shaft head?
Blade adapter from a MTD or Yard Machine seemed to fit the keyed shaft. Center bolt is 3/8" with 24 threads per inch. My issue is the shaft on the Predator is 1/2" longer than my original Yard machine, Briggs and Straton. So I either need to cut the shaft off, or raise the motor on a half inch thick spacer plate to get the blade at the same height it was on the original…
Total capacity is 48 ounces if it has an oil filter on vertical shaft engines. Drain the oil change the filter and add 42 ounces. Start the engine and run for 30 seconds. Shut down, wait 30 minutes and check the level. Add as necessary to reach the full mark. Do not overfill. I highly recommend synthetic oil in an air cooled engine.
