allis579 0 Posted September 1, 2014 I need the drive belt for my Allis B-1, but I can't read the MFG # on the spec plate. Can someone give me the MFG # so I can get the parts manual and look up the belt number. Thanks Bob Share this post Link to post Share on other sites
RayS 81 Posted September 2, 2014 Simplicity 725 mfg. no. 990271 and 990272 are equivalent to your Allis B1. You will need the Simplicity manual for the correct numbers. The belt number is 154273. http://bsintek.basco.com/BriggsDocumentDisplay/heCBEN8aqIZrE3CG.5kbp796Dq.pdf Share this post Link to post Share on other sites
