My classic has started striping on the right and left sides a little. Looks like over laps. It never use to do this. I have put new nozzles in it and it still does it. I just ran across these factory replacement nozzles with the little Figure 8 piece in it. Anyone buy these type of nozzles versus just a regular nozzle for replacement.

Every replacement tip I ever bought for my SC'ers had that little thing in it. First thing I do is pull it out with a pair of needle nose plyers. I have no idea what that thing is for but I've tried it with it in there and it seemed to restrict my flow or at least it felt like it did.

OOps! I just checked your link. I guess it's an anti stripe insert....I still don't like it in there. LOL...
 
Russ its a 13hp honda motor with a 4.6gpm 3500psi GP direct drive pump. The pump is brand new from Bob. It started doing it about a month ago but I thought it was because of the problems I was having with the old pump. Well the old pump finally died and I still have the problem with the new one though not as bad as it was.

At the beginning of the season one of my guys dropped it off of a curb and jacked the nozzle threads up on the bar so I just replaced it earlier in the season. Really about the time I got the surfacer back up and going is about the time the pump started going out so I guess it could be something with the bar. I will check and see about the wobble maybe the hard of a hit messed up more than I thought. I have had issue recently with the bar being stuck in place if I haven't ran it in a couple days. I can grap it and pull it and then it is good to go. Liquid wrench has made it alot better than it was. Sounds like to me I have a bearing going out.:confused: Sucks when you talk to yourself in a post.:D
 
The item to which you refer is a flow stabilizer. According to the mfg. {Spraying Systems} this makes the spray pattern more uniform. They only seem to use them on their meg nozzles. Their SS Vjet nozzles don't need them.

I agree that the bearings are the first thing to check. Check nozzle alignment,bent spray bar, nozzle quality etc.

If thats the case its time to rebuild it or replace it
 
The rotating bar in your surface cleaner goes in a circle. BUT it cleans the outer area along the left and right side more because it goes along there more times. In the middle it goes over it less. Basically go Slower.
 
Sometimes it is the concrete that is the problem.

Think about it, where you overlap when cleaning, you are cleaning that strip twice so it is somewhat cleaner than the other areas, making those other areas a little bit darker looking when comparing the two.

Not all concrete is the same, we have a lot of weak concrete here so I have to put nozzles into the surface cleaner that reduce the pressure to prevent the stripes.

Do this check: Go to a place where you did the concrete a while back before you had this problem and try your machine there and see if it does it when it did not do it before. If it does not do it, it is not your machine, it is the concrete at places you have not worked at.......weak concrete.

That is why I keep different sets of nozzles with me so I can lower the pressure as needed for weak concrete.

Too many times people think that concrete is indestructible and you can't damage it. WRONG.

There are a lot of shady contractors that water the mix down to make it more workable and that takes a lot of the strength out right away. You ever see the cream come off with a little bit of pressure? Too watered down and the owner got ripped off with poor quality work.
 
As for those figure 8 inserts....I have used them and then taken them out and I did not see a difference so when I get them I just take them out thinking that it might reduce the flow.

Off topic
I was on your mailing list and would like to be again
same problem with my surface cleaner thanks all for the tips
 
Well guys thanks for the help, I just went out and flipped it over and was able to wobble the bar up and down so I am pretty well 99% that my bearing is going out. I have to big concrete jobs coming so I am going to be jumping on the phone and getting new bearings on the way. Nothing ticks me off more to finish up a nice patch just to see these ugly a$$ strips back and forth. Guess I got some reading to do to learn how to replace them. THANKS GUYS..
 
Any one ever had ghost stripes??? I cleaned a center two months ago It came out perfect no streaks no overlaps just chaulk white PM was so happy compared to the last guys. I went and by a couple days ago after it had rained and you could see areas that it looked like I had missed or went over to fast. Its almost like mold or something was not completly removed.
 
Any time you use high pressure to clean concrete you only remove waht you see and not the mold spores. If you want a perfect job you have to inject SOHC onto the surface to kill the spores. Classic example is when you use a wand to clean concrete like we did in the old days. If you do not inject the surface with SOHC afterwards then 6 month later you got what we call zebra stripes on the concrete that look like some one scribble scrabbled all over it... Other cheaper option is to go slower and do not miss any spots.
