Hi. Newbie here. I have a 2700 psi blackmax. While moving it, One of the wheels broke off and I didn't notice I got dirt in the inlet. I hooked up the hose and it turned on fine but no pressure. I undid the hose and saw gravel in it.
Long story short after disassembling the whole bottom pump (several times) and cleaning all the cavities from debris (As best I could). I put it back together and still no pressure! I wonder if I got dirt behind the check valve ball (where unloader sits). Hate to pay 187 for a new pump but at a loss for a solution.
Additional Dribble:
1. I put new gear oil in the piston chamber.
2. I removed and put back the unloader looking for debris.
3. I can see the ball bearing on the check valve but doesn't look like I can clean in there.
4. I fixed the wheel with JB Weld (No I didn't get goop in there)
5. I also took apart all hoses and handle, cleaned and re-attached.
6. After removing the loader assembly, there doesn't seem to be a way to get to the check valve cavity easily.
