Gcabinet1 16 Posted May 14, 2016 Does anyone know what the specs are for the drive belt on my AC B110. Belt # 2154273SM. Don't want to pay for an OEM. Any good brand you have used with good success ? Good place to buy online? Thanks Gary Share this post Link to post Share on other sites
steve-wis 637 Posted May 14, 2016 That belt is a 42.3 inch long belt, type HB, according to the chart on simpletractors.com. You can find the chart here: http://www.simpletractors.com/parts/belts/belts.htm The last page will show you what the different types are and the dimensions for them. The old numbers are given in the list, you need to drop the 2 on the front and the SM on the end to get the old number, which is 154273. Steve Share this post Link to post Share on other sites
