DBKissel Posted September 8, 2019 Share Posted September 8, 2019 Hi all, This may seem trite, but I needed a replacement fan belt for my 25 Speedster. The original belt is leather and 1 inch wide by about 41 inches in circumference. After some searching with no luck, I tried a current production serpentine belt with the ribs out. It actually works! The Fan pulley has guides to retain it, but the engine pulley has a simple raised "hump" in the center, yet it tracks and stays on. Hope this helps someone.

trimacar Posted September 8, 2019 Share Posted September 8, 2019 A friend recently needed a belt for an early Overland, bought a piece of one inch leather, readily available in different thicknesses. Skived top of one end and bottom of other end to get correct length, contact cemented together, then sewed glued area. That works too! Link to comment Share on other sites More sharing options...
Marty Roth Posted September 8, 2019 Share Posted September 8, 2019 I use a serpentine belt (yes, grooves outward) on our 1915 Hudson - works great Link to comment Share on other sites More sharing options...
LI_BENTLEY Posted September 8, 2019 Share Posted September 8, 2019 Used a serpentine belt for about 20 years after the leather one failed on a tour works great. Link to comment Share on other sites More sharing options...
cahartley Posted September 8, 2019 Share Posted September 8, 2019 I use one as well, ribs DOWN, and it looks and works perfectly. It's the last belt you will ever need to buy. Link to comment Share on other sites More sharing options...

Hi DBKissel, When using a flat belt to drive a cylindrical pulley from another one, or from a capstan, only one needs to have a crown, (slight raised hump in the center), in order for the belt to run true. I have no idea when ancient engineers figured this one out. Oh : and in case no one has yet welcomed you, let me take this opportunity to do so. A welcome as big and wide as AACA itself ! We all look forward to getting to know you and your car(s). - Carl Link to comment Share on other sites More sharing options...
hddennis Posted September 8, 2019 Share Posted September 8, 2019 Just for future reference here is the best antique car part supplier I have ever worked with bar none! John has made multiple belts for me and they come with a lifetime guarantee and free shortening when they stretch which they will do over time. Also they are very affordable. http://www.leatherdrivebelts.com/ Howard Dennis Link to comment Share on other sites More sharing options...
DBKissel Posted September 8, 2019 Author Share Posted September 8, 2019 Not sure what went wrong on my first try with a serpentine belt, but with grooves down, it came off in the first 2 miles and tore it up, so the next one went on grooves out, Just fyi... Thanks for the input and especially the contact for leather belts. also the warm welcome! Link to comment Share on other sites More sharing options...

ron hausmann Posted September 12, 2019 Share Posted September 12, 2019 DBKissel - I’m using a modern serpentine belt on my 1918 Kissel Sedanlette, except for shows. Like yours, it works just great, ron Link to comment Share on other sites More sharing options...
