840-8M-85 HTD timing / synchronous belts are the third generation of high capacity industrial belts offering reliable, trouble-free and economical alternative to chain drives. Compared to chain drives these belts are cleaner, quitter, lower in cost and lubrication-free. They feature an engineered HTD-type tooth profile providing high performance. The belts feature high temperature chloroprene polymer throughout. The helically wound tensile cords are specially engineered, twisted and chemically set stranded fiberglass material.The high performance, woven, nylon based, fabric facing material has been engineered and tested for highly wear resistant performance. The backing is precision ground for smooth uniform running.

My mistake? fixed!
I needed a 3L330 V-Belt and somehow I think either I typed 5L330 although I was using an online conversion chart to match up belt numbers which might have had a typo there. The delivery is always good from MRO. I contacted MRO by email late that night after work with my silly situation and then rather than wait for a reply I ordered the right belt number so I could get the job done. I got a reply the next morning with instructions for the return procedure then the very next day I had the right belt delivered. Then I received another two contacts from the returns agent and customer support agent both telling me not to return the wrong belt and I would be refunded the purchase amount. Outstanding helpful support and the 'fastest delivery in the west'. MRO people are the best all around. Great products and extensive choices. I am retired now after 50 years in manufacturing equipment operations and maintenance with Nashua then Kellogg's but still I love working on machines and fixing things. MRO is a great source for many things even as small as a lawn & garden V-Belt they take care of the little guy too. Great people at MRO Supply.
