Ahubbard Posted May 22, 2013 Share Posted May 22, 2013 I have a 99 mack RD with a 400 etech. My viscous fan clutch is weak I believe. It is time to replace it. I was thinking of converting to a Horton air operated clutch. I am looking for some opinions on this idea. I still have to measure up mine to see if I can find the appropriate parts. Do the make a kit for this? Any input is appreciated. Thank you Quote Link to comment Share on other sites More sharing options...
