MaineDad 85 #1 Posted December 21, 2014 Been searching hi and low for a cross reference part number for an original Gates 2310 v-belt for the pump on my Ark Loader. Anyone know the Napa equivalent? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,503 #2 Posted December 21, 2014 Gates will change to the Napa numbers here http://www.gates.com/all-search-tools/automotive-interchange-search-results Gates 2310 is Napa 4L310 or 4L310W Garry Share this post Link to post Share on other sites

MaineDad 85 #4 Posted December 21, 2014 Thanks guys but I notice a problem. The NAPA 4L310 is 31 inches long. That is way too long. Did Gates update their 2310 since the Ark loader manual was printed? The belt should be around 23 inches long instead. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,503 #5 Posted December 21, 2014 The Gates 2xxx series of belts are cheap fractional hp belts and old as dirt. A 1/2" x 23" belt would be Gates 2230 or Napa 4L230 or the better green belt Napa 4L230W. The Gates number for the green belt is 6823. Garry Share this post Link to post Share on other sites
