Read and Learn: My Polution SolutionTuesday, October 1, 2013
So you say there is dust coming out from the rear of your sweeper. And, it’s pretty bad. The definition of “pretty bad” is different from person-to-person. Let’s reiterate or redefine how badly. A cloud of dust is bad, yes, by any definition. These sorts of things build up over time and just do not occur overnight.
Now, the question is this cloud of dust: i.e. is it coming out of the bottom rear near ground level of the sweeper or is it more the engine grill of the sweeper?
You say both areas. Yes, both are bad (not good). You have a lot of work in front of you. However, do not fret, this can be resolved. By your description I know it is going to be all sweeper related and not the engine.
Let’s get to work and help him get his sweeper back to protocol: First, the dust that is coming underneath the sweeper is all main broom chamber related. Let me explain. The main sweeping broom is attached to the machine width wise and surrounded by a chamber of skirts. These skirts create a vacuum around the broom allowing the broom to sweep large and small debris without creating a lot of external dust. Without these skirts there would be no vacuum and a constant dust plume. As you can now understand, it is obvious the skirts need to be replaced. Usually, this is not a difficult task. There will be usually two skirts behind the main broom. These generally are held on with metal retainers. Remove these retainers and install the new skirts. You then reinstall the retainers. In some instances, the retainers need to be replaced so check this item before the skirts are ordered. You may need the retainers as well. The side skirts are usually replaced in the same manner. Just refer to your manual.
I am going to wait to tell you what sweeper we are working on. It could be a Power Boss SW90 or it could be an Advance 6250. It also could be an American Lincoln 3366XP. But, it’s not.
We are now at the point to start addressing the dust cloud coming out of the engine grill. As I stated earlier it is not a problem with the engine. It’s the dust control vacuum system. A number of items could be affecting the ability to hold the dust in the hopper. Let’s go with a check list:
- Make sure that the hopper is emptied on a regular basis. When the hopper is full the dust has to go somewhere. Just think about it.
- Clean or replace the hopper filter. This filter works on the same principle as a furnace filter, so keep it replaced at least every 100 hours.
- Lastly, check your vacuum motor fan assembly. This apparatus does all of the sucking and always at the top, or near the top, of the hopper. If this goes bad, it can create all kinds of problems. Dust control is one of those problems. This fan assembly could be belt driven or hydraulic driven. Again, refer to your owner’s manual.
Finally, the machine that we are having a dust control problem is the Tennant 6650 rider sweeper. But it could have been every one of the sweepers mentioned earlier in this article.
