Bosch Injector Pump

DonWorrell · Jul 14, 2004

My Iseki TS 2205 has an Bosch K (type) inline injector pump. I just got a manual for my tractor but it doesn't discuss injector pumps much. The pump, I am told, is made in Japan but it has the same design and specs as a Bosch model K pump.

Here is my question. On top of the pump next to the two lines going to the injectors there is a screw in breather covering a reservoir. What do you fill this reservoir with? Oil or diesel fuel?

Don, I can't give you an answer. My Dodge Cummins has a Bosh inline pump and nothing is ever added to it. It gets some oil from the engine. Every big town should have a Bosh repair shop and I would call one of them and find out.

There is a bolt headed screw about half way up the side that is the" fill to" hole and one on the bottom to drain it. It holds motor oil. The later models use oil from the engine internally. Be careful. There is a screw that is an adjustment screw near the fill hole that you don't want to mess with. It only holds a few ounces.
