M4900 injectors

Let us know how those injectors worked..
I've had 3 customers between last month & this, that ordered injectors online..
& barely a 1 worked correctly..
They ended up sending them back & getting their originals rebuilt for less money..
I hope u have better results..

Tractor ran great all morning. Started it later and a slight knocking noise was evident. Any clues?

Did it go away?? if yes, it might have been a little air in the system.. THAT happens when u open a closed system up.. not uncommon.
IF its still there, while its knocking, loosen a line AT THE INJECTOR 1@ a time to hear if it makes a difference in sound when loosened..
IF NOT, retighten & move to the next one..
That's also how u bleed the air from the system.. so if a bunch of air comes out, wait until u get fuel instead of air & retighten.
