Re: Ymar 2QM20 - What Do I Need To Pull The Injectors?

You can try this:

If you have ever tried to remove an injector from a Yanmar engine you understand the need for a tool like this. Our uniquely simple design will allow you to easily remove injectors from any "YM" series (YM1500, YM2000, YM3220, etc) Yanmar tractor engine in minutes WITHOUT damaging the injector like other methods. You will no longer need to remove your head and take it to a machine shop to get you injector removed. Injectors can be removed with the head on the engine or with the head off of the engine. Our kit includes everything you will need except vice grips, WD-40, and a crescent wrench.
A Hoye Exclusive Tool!
The YM2000 is more or less the same engine as the 2QM20, most parts are the same, the injectors are, and the seals also.
You can make a tool by yourself, unscrew the valveholder, take the holder off, put on the nuts again and screw them as far down as the threading allows, put the holder back on top of the nuts, find a big washer with an 8mm hole and lay it on top of the holder, put in an 8mm bolt and screw it down in the hole where the leak oil banjo was sitting. Then unscrew the 2 nuts under the holder, but do it evenly, a half turn each and you will lift the injector from the seat. I've done that on my own engine and it worked out perfectly. Remember to use new washers and insulation washers when you assemble the injectors again.
Best Regards
