Rivers, MB | 2005 9900 IH truck. Running at the upper edge of air pressure. But is purging air out the bottom of the dryer about every 10-15 seconds. Brother and employee changed the governor and the purge valve on the bottom of the dryer thinking that was the problem. Dryer cartridge was changed in December and truck hasn't run very much since then (less than 2000 miles).
Checked for leaks on the lines coming off the governor.
Anything else to check? | |
