This is the first part to a rebuild of our International Harvest 574 Diesel Fuel Pump Injector. The engine is a D239 Diesel and the pump is a Bosch pump if I am correct. We have never rebuilt one of these pumps but a replacement was any where from $1600 to $3400 so we figured we would attempt to repair this one. We found some information about the repair from KZfaq so we wanted to show our success or failure with the rebuild. Hopefully we will learn something and hopefully it give y’all some valuable information as well. Thanks for watching!
