I am a mechanic/shop foreman for the second largest nation wide concrete pumping companies, and believe me pumping liquid sand paper@1000-2000 psi creates about as much wear as an asphalt eater. And I DO KNOW what works or not.. I have bought boca bearings and I've bought just about every bearing manufacturers products known to man and the SKFs I got from Boca were TOP NOTCH!! and I have several vendors in the area to choose from. So far boca beat them by about 10 or 15 bucks per set and you order by the make and model of your engine,with $$/quality in atleast three choices........
JUST MY IMHO JIMMY
