Re: what instrument???
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???

Re: what instrument???
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....Brian - Newton Abbot, Devon, UK

How about end float?

Re: what instrument???
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.
