HB blew up (updated)

Recommended Posts

Last pass blowing snow on Tuesday.

This is a not so good pic of the right side of block when sitting on the tractor. And this is what I found in the oil pan.

I am going to replace the 12 with a 16. The 16 has a gear starter and I don't know how to wire it so I might switch it over to a starter/generator. Jeff

Changing over to a later model with the gear starter is not a big deal. Been there done that. It does require some rewiring but I don't believe it to be too difficult. Just remove the standard voltage regulator, wire the bat feed (BAT term on standard regulator) to the bat term on the voltage regulator/ rectifier and if it has a starter relay already then the switched battery goes to the starter as seen in the photo of my now sold B112 w/ a 16 hp B+s.

I thought a late model 16 would not drop into an Allis frame because the large frame tractors have kind of a bucket the engine sits in and the FDT frame is different, particularly with regards to the oil drain. Did you have to swap pans or does a late model 16 just bolt in? What about the drive shaft? Do you use the old one or need to use the one that came with the new engine?

Same oil pan. Sometimes you may have to remove the pan and turn the inlet?outlet for the oil around so it aligns with the AC frame holes but it's the same otherwise. The same booster fan is on the front so the driveshaft bolts right up too. Almost as if they were made just for this.:D

Jonathan, Once you get to the later models, such as the early landlord and B-10 models the briggs engines are fairly interchangeble. Only the early models like the simplicity 700, 725 and the Allis B-1 need frame modification for the later and bigger engines to fit. Specifically there is a cutout in the frame that allows the larger engines to fit. Occasionally the engine pan will need to be reversed for the oil drain plug to be in the right place.

      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
