MtAdamsMack Posted June 20, 2013 Share Posted June 20, 2013 does anyone know the engine turning sequence for valve timing on an 865 engine? firing order is 15486... We started with number 1 at top center and both valves were closed. turned the engine one revolution back to "TC" and both seemed closed on 5 as expected so we adjusted those, turned it once again and went to number 4 but the exhaust valve seem closed. Is there something we are missing on the procedure? Does one turn of the engine not get the next cylinder to TC?

j hancock Posted June 21, 2013 Share Posted June 21, 2013 AT TDC set No. 1, then turn crankshaft 1/4 turn clockwise and adjust No 5., etc. following the firing order. 1 5 4 8 6 3 7 2Some balancers are marked with four timing marks at 90 intervals showing TDC for each cylinder piston.Early balancers only have No 1 TDC, use a marker to make three more TDC's 90 degrees apart for adjusting valves.Jim Quote JimIt doesn't cost anything to pay attention.

MtAdamsMack Posted June 22, 2013 Author Share Posted June 22, 2013 perfect. Thanks jim. That s a huge help. Can you confirm clockwise and not counter-clockwise?

j hancock Posted June 22, 2013 Share Posted June 22, 2013 Yup, Clockwise.Do NOT go counter-clockwise. That will make a mess! Quote JimIt doesn't cost anything to pay attention.

MtAdamsMack Posted June 22, 2013 Author Share Posted June 22, 2013 Clockwise for sure. once we cranked it that confirmed the direction. also got some brake clean and steel wool on the balancer and found the 90 degree markings. runs like a top now--smooth as can be and no smoke. Thanks again. that was a huge help Quote Link to comment https://www.bigmacktrucks.com/topic/31642-865-valve-adjustment/#findComment-190176 Share on other sites More sharing options...
