MACKPARTS603

BUILD DATE 2-25-1971

I LOOKED UP A 96 CH613 AND A 99 CH613 AND BOTH TRUCKS CALLED FOR THE SAME CRANKSHAFT

RH WINDSHIELD PART NUMBER 9QT515A, LH WINDSHIELD PART NUMBER 9QT516A

MACK IMPACT IS NOT RECOGNIZING THE 414KB420A NUMBER, LOOK ON THE MAIN PTO HOUSING CLOSER TO THE TRANSMISSION FOR A 52KC CASTING NUMBER. BOTH SMALL AND LARGE PTO' S TAKE THE SAME CYLINDER, JUST DIFFERENT BRACKETRY AND LEVER ON PTO SHIFT RAIL

I SOLD A LOT OF MACK REAR MOUNT PTO'S IN THE 80'S. I JUST CHECKED THE MACK DEPOTS AND THE PARTS FOR THE LARGER PTO'S ARE STILL AVAILABLE

THERE WERE 2 DIFFERENT AIR SHIFT SETUPS DEPENDING IF YOU HAD THE SMALL 51% PTO OR THE LARGER 75 OR 90 % PTOS. I BELEIVE MOST OF THE PARTS ARE STLL AVAILABLE, JUST NEED TO KNOW WHAT PTO YOU HAVE. THERE SHOULD BE A CASTING NUMBER ON THE MAIN PTO HOUSING
