PC150 / PC160 / PC180 / PC180L / PC200EL / PC200EN / PW170 / PW170ES / PW180
HARDNESS: TEST
OUR PIN: ROCKWELL HARDNESS SCALE # 58
OEM PIN: ROCKWELL HARDNESS SCALE # 54
- IN FIFTY YEARS OF TRIAL AND ERROR, WE HAVE FOUND THAT MANUFACTURE "A" BUILDS A BETTER PIN FOR THIS MACHINE THAN MANUFACTURE "B". MANUFACTURE "B" DOES OTHER PINS BETTER THAN "C" OR "A". WE HAVE DONE THE HOMEWORK AND THE TESTING ON THESE PINS & BUSHINGS.
- THIS IS THE BEST PIN FOR THIS STYLE OF LOADER ARM. IT HAS THE STRENGTH, DURABILITY AND LONG LASTING, YOU WOULD EXPECT FROM KOMATSU. BUT....... OUR PIN IS HARDER AND LASTS LONGER THAN THE KOMATSU PIN. IT SHOULD AND WILL LAST FOR YEARS.
- CHEAP CHINESE (EBAY) PINS & BUSHINGS ARE MADE BELOW MANUFACTURE SPECS! OUR PINS ARE MADE ABOVE MANUFACTURE SPECS.
- THIS IS THE ONLY BEST REPLACEMENT FOR THE OEM PIN. HOPEFULLY, WE CAN SAVE YOU SOME MONEY TOO.
