B-110 Fastener questions

Recommended Posts

Are the inserts that these thread into just ordinary 5/16 cage nuts? I'm trying to get all the parts together to re-assemble the B-110 and want to order everything in one shipment if I can. (Yes I know I'm dreaming and will be a regular at the hardware store before it's all over, but I have to try!:D) Thanks

Thanks for the info. however as i further dissasembled it I have a few more fastener questions: The 7/16x14x1.5” bolts the attach the frame to the BGB don’t have a grade listed in my parts book. Are these Grade 5 or should I use 8? The 7/16x20x1.5” fine thread bolts that attach solid steel block under the engine at the front of the tractor don’t have a grade listed either. Are these Grade 5 or should I use 8? I lean to 8 for these since they are under such load, but not sure. Also does anyone know a good source (And size) for the J-nuts that the grill mounting screws thread into

If the bolts have no markings, they are grade 2. If they have 3 dashes, they are grade 5. If they have 5 dashes, they are grade 8. Also, a lot of the mounting hardware is available through your dealer if you can't find it at the hardware store.

Conversely, I prefer to use Grade 5. Their yield strength isn't as high as the Grade 8's but they more ductile and should have more than ample strength for our tractors. Kind of like Ford vs Chevy. Choose your poison and live with the results.

      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
