Today I finished up removing the injection pump and injectors from the 806 due to the injection pump leaking. I have a few questions, and I apologize in advance if these have been answered before. As I was pulling out the injectors, the brass sleeve came out with three out of the six injectors. What is the best way to install new sleeves? Should I be worried about the other ones leaking? I had to destroy the sleeves to get them off the injectors to be sent to the shop. I had the coolant drained and was as ready as I could be for it to happen, I was just hoping it wouldnt happen! The reason for pulling injectors was to do them along with the pump. I just thought that would be the right thing to do since we have never done them or the pump since weve owned it.
Also, this tractor has an M&W turbo installed and when I was ready to pull the pump, the timing was set at 6 degrees BTDC. I see the book calls for 8 degrees BTDC. Was there any advantage to running it at 6 degrees? Tractor ran decent but has always started hard, just assumed it was either from the leaking pump or just an engine that has 6600 hours.
Any advice, or tips or experience is appreciated. Pump, injectors and lines are going to BK diesel in Dubuque, IA. Thank you.
