how to remove the fuel injectors on a John deer 2120?

This could be a similar engine to the 2030/2130, I think.

The injectors are very thin and dilicate so you should probably find new ones or know someone who can refurbish them before touching them. Get new washers for fuel pipes, they will leak.

Take off the exhaust manifold (all the other stuff as well) and remove the screws from the forked retainers on the injectors. Use whatever tool you can to work the injectors loose (vicegrips). Try to be careful, they are easily damaged.

Also, we had problems with low oil pressure until we replaced the balancer and crank shafts and almost everything else.
