ForkliftJim67 Posted October 5, 2010 Share Posted October 5, 2010 I need to pull the injection pump off my 1983 Mack E6 350 two valve. Does the motor have to be set in any special postion in order to remove pump? If not, will pump only go in one way so as not to lose pump timing?

Lmackattack Posted October 5, 2010 Share Posted October 5, 2010 you should be able to remove the pump without re setting the timing. the pump should be "offset Keyed" so that it can only go back in one way. just mark the pump so that it goes back in the same and dont crank the engine while its out.
