BGB lube?

Recommended Posts

Someone probably used what they had. Like Greg C said, 80-90w Gear oil is the fluid I use. Do not over fill, the BGB takes a fixed amount of gear oil, before you flood the seals and make it more prone to leak. Later boxes had a dip stick, early ones you need to keep track of the amount you put in. Check a repair or owners manual for the exact amount. GregB

Transmission fluid would likely be the last thing I would put in a gearbox. You would do better with HD30 oil than fluid. Best will be the multiweight 80/90 like what belongs there, as it will have more of a tendency to 'stick' to the gears during operation. If it is too thick for your liking, try lighter weight, or a good multiweight engine oil, such as 20w50. Just an opinion, though.

Simplicity specs for the BGB call for 90 gear oil prior to 1975 and Simplicity muti-purpose trans fluid thereafter starting with the 7000/7100 series that use a dip stick.

      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
