Just installed a new pressure plate, clutch, throw out bearing,pilot shaft bushing, and had flywheel surfaced for my 1951 3100 with a 1954 235. Has a 1964 SM420. When I ordered the clutch kit for a 1954 ( I assumed went with the motor), it didn’t look like the one I took out. I measured the clutch and pressure plate. It had a 10 3/8 clutch and 10 1/2 “ pressure plate. Research told me that this was a 1963-76 clutch that the PO must have put in.I ordered that one and installed it. Seems to fit. Trying to adjust linkage. Had to adjust linkage rod all the way out. Seems odd to me. Put together without a spring retainer on the pivot ball. The sloppyness doesn’t seem to be right. Any suggestions? Old guy knowledge really needed here.
