You will need to remove the plate on the front of the timing gear cover directly in front of the injection pump. Shut off the fuel supply from the fuel tank. Clean the left side of the engine to prevent dirt entering the injection pump when the fuel lines and injection lines are removed.
where can i get this rebuilt or can I change to a newer style off a B-275 or other tractor that used the BD-144 diesel engine ? and how do I find out what units are compatible and how to go about the swap out. the pump is ih 706235-r91 cav bpe4a its the inline type with pneumatic governor. the #4 piston is not right and pours fuel out the overflow pigtail. Hello all, this is my first tractor (International Harvester B-250 Diesel BD-144) and to get it running the injector pump needs fixing.
