Hi brian..
Its actually a question from college work..its says..assuming the compressor needs to be rebuilt-after installing a new crankshaft what measurement would you take before proceeding any further...it then asks what instrument would u use to measure this???
Any guesses???

am jealous on 2 counts.
1st- there were no college courses to do when i served my time
2nd- if there had been there wouldnt have been the internet to do cheatin on! :-D
dont you take notes or get some instruction before they ask you questions like this?

I would measure that current draw is not excessive.
That mean I would use Ampere meter.

Sorry, the question is still a little open-ended.
Is the compressor fully rebuilt and connected, regassed etc or are we still at the stage of fitting the crankshaft ?
The amperage check is good as above.
If still being assembled then a dial test indicator to check the shaft is square, micrometers, feeler gauges, all sorts of things....

How about end float?
It all depends on what sort of compressor it is. the main checks I would do are for end float (dial gauge), shaft allignment (dial gauge), journal size ( micrometer or vernier). But looking at the question again I would go for the end float measurement with a dial gauge or DTI if that is what you know it as.
