Pulley help

Recommended Posts

Anyone know part numbers or where to look for a front PTO pulley for a 16hp Briggs cast iron motor with a inch and a eighth crank. I need one for my B110/112 so I can operate the snow blower. Also looking for the engagement rod and brackets for it. The blower is the single stage 36 inch.

Thank you.

Those machines, unless it has had an engine conversion to something else will have a 300421 model twelve horsepower single cylinder Briggs engine which comes back with a part number of 2025291 for the front pulley. I was not able to find anything that it would cross over to. If you do manage to find the pulley, make sure the shaft has the key way in it or you have one on hand. Hope this helps!

The OEM pulley for the engine shaft was cast iron and 4 3/8" diameter; it had a 1" hole, the diameter of Briggs SS engines of that era.  I'm surprised you have a 1-1/8" diameter shaft, even the Chinese made 16 HP SS Briggs I purchased in the early 2000's had a 1" diameter shaft.  Here's a pic of the pulley mounted on my B-110:

This pic shows the various components of a FDT snowblower:

Note the "fingers" in front of the engine pulley; they're important - they keep the belt on the pulley and also assist in keeping the belt disengaged when the hitch clutch tension is released.

The briggs that I have in it looks just like the ones that were in my System 7016 & 3416H old single cylinder cast iron Briggs.  By the looks of the photos of the blower I am missing 3 parts.  The cover for the belt,  off and on shaft and the bracket that supports it.  The allis in the photo looks just like mine.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
