You should use what the pump manufacturer recommends. Typically a 30wt non-detergent (non foaming) oil. Do not over fill. If there is a sight glass half way is normal. Or if it has a dip stick follow the mark there.

Comet axd 3020 will not build pressure


junk axial wobble plate pump. Usually axial pumps are not worth the time to try to fix them. This one has a 5 year warranty , so they think they have a pretty good one. ( I would never buy one) If you want to try to fix it, I would check the check valves first. Take them out and see if some are broken or not sealing properly. There is a valve kit available.
The other likely problem is your unloader valve. If the seal is shot or the valve stuck open the pump will not build pressure.

I live in the naples fl. area .--where can i get my comet axd 3030 pump rebuilt and what is the cost?


These AXD pumps usually do not require a rebuilding process. What happens is the unloader / bypass valve gets stuck and you do not get any output pressure. What you can do is tip you pressure washer so that the input and output fittings are vertical and actually dump oil into the water supply hole. (3 oz at least) Slowly pull the recoil (ign off) and add a bit more oil and let it sit overnight. Then the next day once again pull the recoil through and let it sit another 10 minutes. Then connect all hoses (Purge the air in the garden hose) BEFORE connecting the main water supply and start the unit then running at MAX SPEED rapidly fan the wand trigger. What your doing is cycling the unloader valve. Do not do this for more than 2 minutes if the pressure does not suddenly start. IF the pressure builds continue at lease another 30 rapid cycles of the wand trigger.
I lost count on just how many pressure washers I have brought back to a good working service life by just doing the above. I do know it is a substantial number.
Give this a try before you go off on the need to rebuild the pump avenue.

I have a northstar pressure washer with a comet pump AXD 3020G that will not build up pressure, can you give me some ideas on what may be wrong ,I have checked the screen on the inlet ,it is clean


Normally, it is one of three things.

1.) The high pressure seals are bad

2.) There is debris in the check valves

3.) the unloader is stuck in by-pass.
