Can anyone help me with a technical drawing, or explanation of how the cam (K1211-4441-0) and retainer spring (K1122-4444-0) are meant to work and fit together to turn the deck height adjustment? In disassembling my cam rod, cam, etc. I seem to have reassembled it incorrectly as it now won't turn the rod-mounted height adjuster - not sure what I've done wrong! It's in a very fiddly and hard-to-access gap in the steel, lift link support plate.
