Sounds right
2 driven plates (2mm each)
1 drive plate (3mm)
1 dished driven plate (1.5mm)
6 of each driven/drive (2mm/3mm)
gives you ~38.5mm (since the dished plate may alter the height a fraction)
allowing for wear down to 2.8mm on each drive plate, a minimum of 37.1mm
38.5 - (0.2 x 7) = 37.1
minimum spring fee length should be 36.5mm
I'm pretty sure (from memory) the dished plate has a punch mark on it which should be outwards, but can't find a reference to it in any of my manuals
