I have a 59 international 660. A couple years ago the tractor died and wouldn't start. I tore into it and found the shaft in the injector pump was broken. Diesel Algae. I sent the pump to a shop and was told they can't rebuild it because the shaft was broken and that meant it was something in the pump that was causing too much pressure. So, I started looking for a 660 pump. I found one but they would not take my core because of the broken shaft. I finally found a place that said they had a pump. I gave them the numbers off the pump and they said we were good to go. So, I bought it and the one I was sent is for a 560. I don't know a lot about the details of these pumps but I have read what I could find about them on google searches and in my manual. I know the 660 runs at 2400 rpm and the 560 is an 1800 rpm. I also know when timing this pump to the motor that the 560 should be set at 3* BTDC and the 660 at 5* BTDC. I have read in several unrelated articles to set it at 7* BTDC, is this true for better power, fuel savings, but harder to start? My question here is what is the real difference in the pumps between a 560 and 660? It is difficult to find a 660 pump (2400 rpm) but easy to find a 560 pump (1800 rpm.) So can I use this one and still have a true 660? if I time it at 5* BTDC? Or am I going to have a 560 hp rated 660? Thanks for any info you guys can give me.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
