Baxter Posted October 16, 2015 Author Share Posted October 16, 2015 This is a Bosch pump on a 350 mack mechanical. Was told that aE6 pump could be removed and would go back on without timing. Do not know about the E7 pump though. Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted October 16, 2015 Share Posted October 16, 2015 First thing you need is a timing light to get the engine in position to remove.That means a sensor is screwed into the side of the governor housing and you turn engine in engine rotation until both lights are on.Then pull the front timing cover off and remove the drive gear and four bolts that hold the pump to the block.To install set the engine to the specs of timing with out turning engine off of the stroke you removed it from and then install pump.To set the pump to engine timing install the timing light sensor in the side of the governor housing and turn pump from the drive end until both lights are on.Install drive gear and tighten bolts then back engine up against engine rotation 1/4 turn.And then turn engine with engine rotation the engine timing specs and both lights should be on again.When you remove the engine light sensor then pour some clean engine oil into governor housing.If you want to guess at the timing to keep from using the timing light then turn the engine until the spade in the opening of the governor housing is lined up in the middle of the opening but I tell you the engine timing is very important to be correct.

theakerstwo Posted October 16, 2015 Share Posted October 16, 2015 Even a E6 ambac needs the timing check or timed when you have it off.One way of looking at it is who knows who had it off the last time and the instruction he had to install.
