Joey Mack Posted February 28, 2022 Share Posted February 28, 2022 I have a customer that has a '96 RD. He wants me to pull the elec. inj. pump, and install a mechanical inj. pump.. I assume both are robert bosch based on the year. But I havent gotten all the details yet.. I have never done such a swap... would I just use the pump degree settings from the mechanicle pump, and install it that way.. I have only ever re-installed the pump's that were on the engine originally.. I have the tool's, most of the knowledge and all the Mack books.. I welcome any help... Joey Mack...

Popular Post theakerstwo Posted March 1, 2022 Popular Post Share Posted March 1, 2022 I have did them both ways.Time them like the pump your using on its own engine and try not to advance more than two degrees if any.All so watch for the oil drain back plug in the block.These two of mine that i did one was a Vmac 11 and i installed a mechnical pump on it.The VMAC engine does not plug the oil return in the block.The mechaical pump gets the return hole in the block pluged.The injector lines need changed also. 2 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/69302-swap-an-elec-inj-pump-with-a-mechanicle-inj-pump/#findComment-490622 Share on other sites More sharing options...
Joey Mack Posted March 1, 2022 Author Share Posted March 1, 2022 Thank's Glenn.. I was hoping you would respond.. my cust. has 2 engines, im pulling the pump off one and putting it on the other. so I should be able to see the plug you mention, and as far as the lines, I hope to use the lines he has, i expect that I will have to buff the ends so they seal.. I figured I would use the timing for the pump that I am keeping.. thanks again.. jojo Quote Link to comment https://www.bigmacktrucks.com/topic/69302-swap-an-elec-inj-pump-with-a-mechanicle-inj-pump/#findComment-490627 Share on other sites More sharing options...
theakerstwo Posted March 1, 2022 Share Posted March 1, 2022 On the injector lines make sure and blow them out before you install.I have many lines laying in the shed and i think ever one of them may be stopped up.The last pump and lines i took off and stored i wrap tape around the ends.There is some kind of small bee like animal that gets in there and builds a nest inside of the lines. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/69302-swap-an-elec-inj-pump-with-a-mechanicle-inj-pump/#findComment-490639 Share on other sites More sharing options...
