stylus contacting end of crankshaft; push
crankshaft fully rearwards and zero gauge.
5. Push crankshaft fully forwards and measure
end-float.
6. If end-float exceeds 0.05 to 0.15 mm, remove
crankshaft, fit combinations of standard and
oversize thrust washers to achieve correct
end-float.
CAUTION: Variations of thrust washer
thicknesses on each side of crankshaft
must not exceed 0.08 mm.
