Yanmar Injection pump removal

Yanmar Injection pump.
1984 13 hp. Two cylinder Yanmar diesel engine.
I need to remove the injection pump to have it rebuilt.
Iíve unbolted everything and hammered a screwdriver blade in to get it separated by ľ inch.
Do I need a wheel puller to get it out or am I missing something?

Look for an access hatch just above it. There may be a rack connector inside that may need to be lifted off. (Totally off the cuff thinking of discussions about an older engine but it was not intuitive even with a few drawings)

Re: Yanmar Injection pump removal

Before removal you should set the engine to TDC compression stroke on the first cylinder. The shop that rebuilds it should give you the pump back in that position. Also you should mark the pump timing to put it back in place correctly. (Some pumps use shims to time them). What engine is it? There are a lot of Yanmar manuals available for free on the net.
