The ususal problem on the Diamond Pacific pumps is the front bearing oil gets contaminated with dust/mud over time and turns into a thick black grease.  The belt then slips and the pump stops turning.   

I tear down the front section every few hours of use and clean the bearing and shaft and put clean oil on the bearing and shaft.  The hardest part is putting the piston shaft back together but it is really easy if you modify the shaft by using a Dremel to make it into a point.  I can tear a pump front end down, clean it, lubricte it and put it back together in about 7 minutes. 

I have contacted Diamond Pacific about modifing the shaft but so far I do not beleive they have made any modification.  I find that all of the major equipment companies are very difficult to deal with when improvements to their designs are presented to them for improving their products.  I cannot figure out why as I am not asking for a single cent or even any sort of recognition.
