FOR THOSE OF YOU WHO THINK YOU HAVE TO USE A TOOL TO INSTALL A STOCK TYPE HARMONIC BALANCER, HA HA HA. WE BROKE (1) AFTERMARKET CHEAP PIONEER BRAND BALANCER BECAUSE OF A BURR ON THE CRANKSHAFT SNOUT IN YHE LAST 15 YEARS. GIVE ME A BREAK, YOU GUYS PROBABLY RUN AWAY FROM A PRESS WHEN ITS GOING TO POP OFF A BEARING OR SOMETHING. STOP READING THOSE MAGAZINES AND PICK UP A WRENCH. USE THE TOOL IF YOU LIKE OR HAVE A FLUID DAMPER, ETC.. BUT DON'T SIT THERE AND SAY THE BALANCER IS GOING TO BREAK IF YOU POUND IT ON. GO TO YOUR LOCAL ENGINE REBUILDER AND SEE HOW MANY TIMES THEY USE THE TOOL BESIDES TEARDOWN TO REMOVE IT.
