Sorry Dave, too much stuff to try to jot down from memory, should have looked in the parts book, but regardless of years,the idea is there. (Perhaps it was the 1961 Topper flywheel that used the -61 crank pin.) If you assemble a set of flywheels and true them to .001 runout. the gap will have to be even all the way around, as the crank pin holes are machined 90 to the flywheel castings. I'm not exactly new to Hummers either as I have been rebuilding them for right at 25 years now on a daily basis. I don't have that spacer plate, nor have I ever used one. As long as the rod to flywheel clearence is right and the wheels are trued to .001" there's no way they can't be right


Thanks,
Mutt

HELLO, THANK'S MUTT FOR YOUR INPUT, BUT 1961 CRANK PINS WERE'NT STEPPED BUT STRAIGHT.1948-1952 CRANK PINS WERE STEPPED. 1953-1961 WERE STRAIGHT. AND IN 1962 THEY WENT BACK TO STEPPED. I KNOW I CAN GO THRU THE PAINS OF GETTING .010' WAY DOWN THERE ON THE ROD, BUT I DONT THINK PULLING THE WHEELS TOGETHER WITHOUT THE SPACER PLATE WILL DRAW THEM TOGETHER THE SAME. OTHER WORDS THE GAP WONT MEASURE THE SAME ALL THE WAY AROUND THE WHEELS. THAT IS WHAT THE PLATE WAS FOR. I AM NEW TO HUMMER MOTORS, BUT NOT NEW TO HUMMERS. I HAD 1 WHEN I WAS AROUND 13, AND HAVE BEEN AROUNG THEM PRETTY MUCH SINCE THEN. THANK YOU FOR YOUR TIME FEEDBACK AND PATIENCE. NUKL47.
