Truck Repair: Cummins M11 Injector, Valve, and Jake break adustment, cummins m11, accurate adjustment
QuestionI adjusted the valve, injector, and jake break according to specification but it still isn't working properly. Any advice?
AnswerIf you could get me your engine serial number. so i can look it up. What do you mean by not working properly? is the top end knocking. If it sounds like the exhaust valve isn't closing all the way i can almost bet that your jake is tightened down to far. Have had problems with guys in my shop the Jake adjustment on 5 and 6 are up against the firewall and hard to get a accurate adjustment on. But give me afew more details and your serial number and can be of more help to you.
