bighammer48 Posted October 5, 2016 Report Share Posted October 5, 2016 I've got my 48 D-24 engine all back together and ready to run except for the fan belt. The original belt got mislaid and now I'm trying to find a new one. I purchased a Gates 7490 that the parts interchange list on this site suggested. I find that this belt is probably 4 or 5 inches too short for whatever reason. Any suggestions for a belt that will fit correctly? Quote Link to comment Share on other sites More sharing options...
casper50 Posted October 5, 2016 Report Share Posted October 5, 2016 (edited) Measure how much longer you need then go to auto parts and buy one that is 4 or 5 inches longer. When I changed the generator to an alternator I had to buy one that was shorter by 2 inches. Edited October 5, 2016 by casper50 Quote Link to comment Share on other sites More sharing options...
halffast52 Posted October 5, 2016 Report Share Posted October 5, 2016 I am running a gates TR24489 on my Plymouth 3/4 wide 49 3/8 inches long Quote Link to comment Share on other sites More sharing options...
bighammer48 Posted October 5, 2016 Author Report Share Posted October 5, 2016 The Gates belt is approximately 49 5/8 inches, and appears that a good fit would be 52 - 54 inches. Do I take the Gates belt with me so they can see the belt width and depth? Quote Link to comment Share on other sites More sharing options...
MARK Posted October 5, 2016 Report Share Posted October 5, 2016 the !st # is the width of the belt , the last three ate the length [49.0 "], try for a 7450 , or use a piece of string to get a total length Quote Link to comment Share on other sites More sharing options...

DonaldSmith Posted October 5, 2016 Report Share Posted October 5, 2016 For my power steering project, I've got various belts from Grainger Industrial Supply. They seem to be international. I would order a belt on line and pick it up at the store the same day or the next day. If the belt was too long or too short, I would return it for another size. As the project evolved, I would order a few different sizes at a time. Quote Link to comment Share on other sites More sharing options...
