An oil change on a TRX 420 Honda ATV is standard maintenance, and an important way to keep your ATV's engine healthy. Honda recommends every 12 months, 100 hours, or 600 miles: whichever comes first.
Watch the video above and follow the steps below to learn how to do an oil change on a Honda TRX 420.
Step 1. Run the engine for a couple of minutes to circulate the oil.
PRO TIP: You don't need to bring the engine all the way up to temperature, but circulating the oil a little will make it easier to drain.
Step 2. Remove the plastic panels on both sides of the unit. You can pull them out by hand without any tools.
PRO TIP: Removing the right side panel allows you to access the oil filter, and on the left hand side you'll find the oil fill cap.
Step 3. Find the drain bolt underneath the unit to remove the used oil, and get a drain pan to catch the oil. See #7 in the Rancher crankcase diagram to find the bolt's location. Access the drain bolt through the hole in the skid plate, and use your 17mm socket to remove it.
NOTE: Be careful not to lose the crush washer on the bolt. If you need to replace it, Honda has a drain bolt crush washer available for purchase.
Step 4. Remove the old oil filter while the used oil drains. The filter is found on the right side of the engine and can be seen as #4 in our Rancher front crankcase cover diagram. Some oil will leak out, so get a rag underneath it to avoid a mess. Take off the three 8mm bolts to remove the cover and expose the filter, then pull the filter out.
NOTE: There's a spring behind the filter that should remain in place.
Step 5. Replace the oil filter. One side of the filter will have "Outside" stamped in the metal. It's crucial that this side faces out toward you when you install the filter. Make sure the spring is behind the filter and then slide it in place.
Step 6.
Inspect the O-rings on the oil filter cover and around one of the bolt holes for the cover. Make sure they are not cut or damaged. Then, replace the filter cover and the three 8mm bolts without over-tightening them.
Step 7. Replace the right-hand side plastic. There's a tab at the bottom of the plastic piece. Hook it into place first, then push the rest of the plastic into place and snap it.
Step 8. Replace the drain plug. Hand-tighten it first to get it threaded, then use a torque wrench to tighten it to 18 foot-pounds.
Step 9. Refill the engine with oil.
PRO TIP: Honda says the oil capacity of the Rancher 420 is 3 quarts, but we found that can be a little too much. Pour in 2.5 quarts, replace the fill cap, run the engine for a couple of minutes, and then check the level. To check the oil level on the engine, don't screw in the fill cap. Just plunge it in and remove it, then top the engine off with oil to set the level.
Step 10. Replace the fill cap.
Step 11. Replace the plastic cover and you're done.
Now that you've got the engine oil change done on your Honda TRX 420, why not go ahead and change rear differential oil while you're at it? Watch the video below to see how to change the drive shaft oil on a Honda Rancher 420.

More » All ATVs have their own "term" of life. This applies even to expensive branded devices that cost tens of thousands of dollars.
There is nothing to be done about the fact that key components of equipment gradually wear out and fail. But you can increase the life of the components by using quality oil. Even if you decide to buy an inexpensive ATV, you need to find the right lubricants for it. Therefore, let's figure out which oil is better to choose for an ATV.
It should be noted right away that a special oil is used for each of the units of the apparatus. The lubricant composition is poured into:
It is not recommended to save on oil, because it not only reduces friction, but also removes excess heat. Due to this, the mechanisms work correctly, do not overheat and “live” an order of magnitude longer.
Refer to your ATV documentation for information on lubricant formulations.
Each device has its own requirements, so be sure to study them.
Although the manufacturer's recommendations should be followed, this does not mean that you need to buy the first suitable compound. All oils consist of a base and special additives. And it is on the basis that their operational features depend. There are 3 types of oil:
It is up to the rider to decide which oil to put in the ATV. However, experienced motorists are advised not to save on lubricants, since repairing an engine or gearbox will cost many times more.
There are several oil characteristics that a rider should pay attention to. The first step is to determine the viscosity of the liquid. To do this, look at the label. If it has the letter W (winter), then the liquid is designed for low temperatures. The following numbers show what weather conditions the composition is intended for (0 - mild winter, 25 - severe frost).
The situation is similar with summer liquids. There are 5 classes of compositions (by viscosity) from 20 to 60. There are also universal oils that are used both in winter and in summer.
You can recognize them by special markings, for example: "20W40"
You also need to pay attention to:
The API system is used to classify oil by quality. The marking looks like this: S (common name) + A, B, C, D, etc. The lowest quality is marked with the letters "SA", and the highest quality is marked with "SL".
When deciding which oil to fill in an ATV engine, you need to take into account the characteristics of the vehicle itself. Because the ATV is subjected to considerable stress, the engine becomes very hot. This means that the oil must be resistant to high temperatures and conduct heat well.
Plays the role and basis of the composition.
Ideally, you should use only synthetic or semi-synthetic fluid. You need to pay attention to the labeling: the country of origin, season, quality standard.
Important: For gearboxes and gearboxes, you need to use special compounds that differ from engine oil in a set of additives.
The first thing a rider needs to figure out is how often to change the oil in an ATV. Each manufacturer has its own recommendations, but experienced motorists advise filling in new fluid every 160 hours. In this case, the first replacement is performed during the break-in, after the device has worked for 20 hours.
To change the oil you need:
