<div dir="auto">Hi everyone, got my 1st non antique non red
tractor this summer. Kubota 62 horse 4wd. Nice shape overall
and a good price. However it makes a noise that seller said
dealer told him it was a lifter adjustment, but it turns out
not so. We have had this engine apart several times and cant
find anything wrong, bearings are all good, no broken rings,
out of spec bores, pistons all good.
<div dir="auto">At odds trying to figure this out, and dont
want to destroy this engine by running it too much. Just
yesterday, replaced all the injectors and cups with new as
the sound is like a bad injector, but to no avail, noise
is still there. The engine is an F2803 5 cylinder which
seems to be not as common as most. </div>
<div dir="auto">Does anyone know of any</div>
<div dir="auto">Reputable dealers for used engines?</div>
<div dir="auto"> I have attached a link to video where
you can hear the noise. Any and all suggestions and
comments welcome.</div>
