End float measurement

[<simon.halliwell@postoffice.co.uk>]

Hi All,

Can anyone recommend the best way to measure end float on the crankshaft so I
can gauge the size of thrust washers I need to put in?

The engine is from a Mk3, it is on the bench completely stripped down.  Before I
removed the crank the end float measured about 12 thou' but I don't know how
worn the thrust washers are.  Am I best getting some standard size thrust
washers and measuring the end float with them in or is there a more scientific
method?

Many thanks,

Simon.
