7045 engine low on power

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a 7045 that seems tobe missing on one cylinder a little.  Whiter smoke, smells like unburned fuel, not antifreeze.  Engine hadn't been used in 3-4 years, only started about once per year.  When I first started using it this summer, it seemed to be a little low on power.  It has been getting worse, only put about 3-4 hours use on it.  New fuel filter.  Has electric fuel pump that is working.  Assuming good fuel flow (checked earlier, and will check again) is the pump/injectors in need of replacing from the old fuel?
  I tried cracking injector lines and couldn't tell the difference in a bad cylinder.  The tractor was parked due to immobility from bad hyd pump?  Don't remember it being such a dog before.

	You need to be removing the injectors and have them tested/repaired. Mark them so you KNOW which one was bad from which cylinder. You also should run a compression test while they are out to be sure you don't have a blown head gasket between two cylinders or a bad valve.
