Delta 4 Step Pulley Size/Speed/Cat.No. Charts
Larry Buskirk posted a topic in Old Machinery Operating and Restoration Tips
I've found the information in these catalog snips very useful over the years redoing my old machines. But every time I've needed them I've had to look to find them, so I'm putting them here so I can find them easier. Hopefully you will find them useful yourself. Around 1972 Delta changed the catalog numbers. Instead of ordering a pulley and having to specify the bore size you ordered by a specific catalog number. These and other 5 digit catalog numbers were then again changed around 1983. The new numbers were 12 digit. The below links will take you to the 5 digit to 12 digit conversion tables. Part one. http://www.vintagemachinery.org/pubs/detail.aspx?id=1087 Part two. http://www.vintagemachinery.org/pubs/detail.aspx?id=1088 The 718, and 720 pullies were used on quite a few Delta machines over the years. They are commonly found on the 4 speed scroll saws, wood/metal bandsaw, and a few others. The 932 was commonly used on the Delta 9", 10", 11", and 12" wood lathes. This is the pulley that matches the lathe headstock pulley. The 985 is more commonly referred to as the DP 260 pulley. It is the matching motor pulley used on the smaller Delta 4 speed Drill Press's. It is used on both the standard, and Slo-Speed Drill Press's
