I have the PORSCHE 901 transmission rebuild manual and it tells me to have 15.8 to 20.6 FT LBS drag on the DIF.. I'm reading about 5 FT/LB. with the same diff and case ( no gears installed )There is also very slight visitable and feelable back and forth (left and right) at the CV flanges. Should I install shims ? HELP AL

I think you need the gear stack in to measure the backlash. 914 factory manual is missing some data. |
