Good afternoon brethren. 
 
	I have a delemma. I have three GT14 hydro pumps, with rearend. 
 
	I know the mechanical status of only one, the one I replaced on my running GT14. Although it moved forward and backwards, and had trouble going up a hill.
 
	The other two pumps and rearends are on parts gt14s I bought. 
 
	I have people asking if they're for sale. I don't want to sell them junk.
 
	Is there any kind of test, or a way to check these for "good working condition"?
 
	 
 
	Thank you.
