kennydivin Posted December 17, 2014 Share Posted December 17, 2014 I have a E7 350 1992 model mack truck. Just had injection pump rebuilt and was curious if anyone had any ideas on how to get the motor #1 cylinder top dead center to install my rebuilt injection pump.

felicello122 Posted December 17, 2014 Share Posted December 17, 2014 Should be marked underneath under the little square plate on the bottom of the flywheel housing.turn it over if you have the tool till you reach 1and 6 on the markings, i pop the the front valve cover off and you should be able to move the rockers. On the inlet and exhaust valves,,if they are tight you have to turn it over one more time around untill you get to 1 and 6 again that will be TDC on hole 1 Quote Link to comment https://www.bigmacktrucks.com/topic/38131-how-to-get-motor-cylinder-1-top-dead-center-to-install-injection-pump/#findComment-270689 Share on other sites More sharing options...
