I have a 6080 that needs the drive shaft seals for the injector pump, they are a cup type seal. Can some one tell me where I could find them?
Thanks Brian

I got the seals now the tractor only runs a minute or two.
What I found was on the injector pump it's a Roosa master, If I loosen the 1/2" plug on the side it will run fine. I believe the return line may be plugged. Can any one give me some insight where to start ?
Thanks Brian

Look ontop of the injectors and theres the return line , id remove it completely and blow air thru it then loosen the tank cap and blow thru the plastic line returning to the tank ; sounds like you may still have air in the system , if you loosen two injector lines and get full fuel thru them then tighten,the engine should run then you can bleed the other two , 6080,s are a booger to get all the air out

It is time to remove the pump and have the weight retainer replaced. The rubber from the retainer pluged the check valve. MACK
