K so doing some seasonal work on the 38 alliance we bought this unit used. And was unsure what it's been through. So going through it after two summers of use pulled the swing lever and splines hit the floor.... ok swing tube is finished. So looking at the cylinders with the s tube out of the way there is a buildup of concrete on the top of the reduction rings were the cylinder meets the reduction rings. This unit always gets a good washing after every job. Could this be a sign on how worn those cylinders are?

I'm always thinking if you keep the water in the flusshingbox and it doesn't run pas the pistons (when parked with pistons both standing about halfway the cylinder) You are good. But I'm not a mecanic though ;-) Feel free to correct me!

Ok well good to hear. Got it all back together. New swing tube cutting ring, bearings, cups, all ready to roll for spring. Pretty good for a novice. Pump mechanic. Only three phone calls to the boys over at alliance in alder grove bc 

Where are you guys located?  We go to Gastaldo out in Annacis Island.  Awesome group of guys.
