For the NP149, New Process never installed a 1.5" chain, nor do we see it in the parts books, But if you look into the NP263HD. this unit - and maybe others, have the 1.25" chain (same PN) as the NV149, but also have the 1.5" chain & sprockets as a HD option. I bought and installed the 1.5" kit. Little close to the Viscous Clutch body but does clear it.
