When you're looking for the right honda gx390 air filter part number , you've most likely noticed that there are a few various versions floating around online based on your specific engine setup. The most common part number you'll run into for the standard GX390 is usually 17210-ZE3-010 , but occasionally you'll see this listed as 17210-ZE3-505 . For your most part, they are interchangeable dual-element filters that suit the vast majority of these 13HP engines found on pressure washers, power generators, and wood splitters.
Having the part number right will be a big offer because the GX390 is definitely a workhorse, but it's the huge breather. It drags in a lots of air to generate that power, and in case the filter is definitely the wrong size or poorly produced, you're basically welcoming dust and grit to go upon a tour of your cylinder walls. That's a quick method to turn a reliable engine into the paperweight.
Which version perform you actually have?
Even though the particular honda gx390 air filter part number 17210-ZE3-010 will be the "standard" a single, you have to take a look at your real air cleaner casing. Honda made these engines with a few different consumption styles. Many people have the "Dual Element" type. This will be the one with a paper filter inside and a gray or dark foam sleeve (the pre-cleaner) wrapped about the outside.
If your engine is on a piece of equipment that works within incredibly dusty conditions—think concrete saws or even some construction pumps—you may have what's called a Cyclone air cleaner. These types of are much heavier. The filter for those usually has a different profile. It's always a good idea to double-check the physical dimensions of your older filter before you hit "buy" upon a website. The conventional dual-element filter will be roughly 4 1/8 inches long, 3/4 inches wide, and about 3 1/2 ins tall. If your own looks way shorter or much leaner, you might have got one of the particular specialized low-profile versions.
OEM compared to. Aftermarket: Is this worth the extra money?
This is actually the older debate. If you research for that honda gx390 air filter part number , you're going to observe the genuine Honda parts for probably fifteen or 20 bucks, then you'll see a package of five "no-name" filters for the particular same price. It's tempting to look inexpensive, especially if you're running a company and burning by means of filters every month.
Honestly, the genuine Honda filters (the OEM ones) usually have even more pleats within the document. More pleats suggest more surface area, which means the engine can breathe easier for a longer period of time before the particular filter gets clogged up. Aftermarket filter systems can be alright for light use, but some of them have leaner foam or papers that feels the bit like the coffee filter. In case you're running the high-end pressure cleaner or a welder, sticking with the official Honda part is usually the particular safer bet for the long haul. You don't wish to save ten bucks today only to have to replace the piston rings following year because the cheap filter let a few silt through.
When in case you really swap it out?
Don't just wait for the engine to prevent starting. By the time a GX390 is struggling to remain running because of the air filter, it's already been working "rich" for a long period. That will means it's burning up too much fuel rather than enough air, which leads to carbon buildup on your valves and spark plug.
A good guideline is to check it every 50 hours of use. When you're working within a clean garden, it might continue 100 or a hundred and fifty hours. But if you're out in a dry field or a dirty construction site, you may want to look with it each day. When you pull the foam pre-filter away and the paper underneath is starting to look dark or gray rather of white or bright yellow, it's time to make use of that honda gx390 air filter part number to get a clean one.
Don't forget the polyurethane foam pre-filter
The particular cool thing about the GX390 set up is that the foam sleeve will about 50% of the work. It catches the best chunks—grass clippings, bugs, and heavy dust—before these people ever hit the delicate paper component. You can actually wash this polyurethane foam part.
Just pop this off, wash it in certain warm soapy water, rinse it out, and allow it dry completely. Once it's dry, most pros recommend putting several falls of clean engine oil within the foam and squishing it around (don't saturate it, only a light coat). This makes the dust go through the foam better. If your foam pre-filter is definitely crumbling or offers holes in this, don't try in order to save it. Simply replace the whole assembly. A new filter kit almost constantly includes both the paper element and the foam.
How to exchange it out with out making a mess
Changing the filter is probably the easiest maintenance task you can do on these types of engines. You usually simply have to unscrew the wing nut on the top of the plastic cover, pull the cover off, and then there's another wing enthusiast holding the filter itself down.
Pro-tip: Prior to you pull the particular old filter from the intake stud, take a clean rag and wipe down the outside from the air cleaner housing. You really don't want to knock a bunch of loose grime down into the particular carburetor throat while you're lifting the old filter out. When the area is clean, swap the filters, guarantee the rubber gasket at the bottom is sitting level, and tighten the wing nut down again. You don't have to crank it with pliers; finger-tight is plenty.
Signs your filter is bread toasted
If you've forgotten when you last changed it, the engine can usually inform you. One particular of the 1st signs is really a reduction of power. If your pressure washer seems like it's lost the "oomph" or your generator is hunting/surging, it's often because it's starving with regard to air.
Another big giveaway is black smoke coming from the particular exhaust. That's unburnt fuel. Since the motor can't get good enough air by way of a clogged filter, it drags more gas, and that extra gas doesn't burn cleanly. If you observe that black puff when you throttle up, it's an enormous red flag. Pull that honda gx390 air filter part number out there of your information and get the new one purchased immediately.
Maintaining a spare readily available
Since the GX390 is like a common motor, it's honestly a good move to simply keep an extra filter in your shelf or inside your vehicle.
