I picked up a 1998 Yamaha Big Bear 350 4X4, and decided to do an Oil change as I had no idea how old the fluids were. This video covers a complete oil change, which includes the main engine oil reservoir and the middle transfer gear oil reservoir.

I'm glad there are guys like you showing us how to DIY our ATV. Great video, thanks
Glad to help
Thank you for the video. I just bought a '97 Yamaha Big Bear 350 4x4. I have never owned (or ridden an ATV) before. I'm learning about how to care for it. This video was very informative. With the help of a friend, we cleaned the carburetor to get it running.
Thanks for watching. I'm glad you got it running, the big bear is a awesome atv, very reliable and easy to work on.
By far best oil change video....I've watched a bunch... Took me a minute to figure out the nut to check the oil pump.
Thank you so much for showing such a nice detailed video. I had no idea about the second little drain plug. 🙏🏻
Thanks for posting. I learned something. Now I know about the 10mm drain plug drain for
a full oil change.
Awesome video. Great detail , and explanation Had no idea i i was leaving some old oil in .
I have a 1998 kodiak400 man it's a beast. Changed a few parts and runs great. A diamond in the ruff .
They are definately worth keeping. I have a few new parts to install come spring and im sure it will last many more years.
Thank you for the video. It helped, hopefully you have more videos to share for this atv.
Awesome video man thanks I just bought a1998 kodiak 400 and this video answered all my questions
Great to hear! Yamaha makes some great atvs.
Nice. This will be replayed a few times to get mine done. Thanks
I'm glad it could help.
My drain had a spring on top of it? Do all of them? First big perchuse i made at 16years old. Still runs and looks awesome. Made alot of memories and took way better care of it then ones my dad bought me. ❤

You are welcome! Glad it helped.
Well done, thank you
great video
Thanks!
Just bought a 87 Big bear 350. Only have 230km on it, an old man bought it new and only used on the 90s to run around the yard. Its in mint condition. Not a scratch anywere. Gonna change all oils now 😎
nice, mine has just shy of 10000km on it, so yours has alot of life left in it! They are great atvs.
@@OffGridFreedom yeah the are funny old bikes. And real build quality back then.
Hey man, have you changed the rear caliper brake pads on this quad yet? would love a vid on that if possible, can't seem to find one from A to Z, thank you!
Thanks man!
You bet!
Great vid mate 👍. I was gonna attempt to do this the weekend but started her up today and s**t load of oil squirted out the boot going to the transmission. Gonna try and figure out what's broke tomorrow. 😔
Thank you, sorry to hear about your issue on the big bear. Hopefully its just a failed seal or something easy to fix. These are great atvs so they are worth fixing up if possible!
@@OffGridFreedom It is pretty good, managed to get out and jack it up the other day and the swing arms got about 10meters of play in it lol. I think the bearing have evaporated 😂😂 so ill be fixing that as well. I want it ready for the snow but need a front shaft as well as its only 2wd at the moment. Parts are pretty scarse round here unfortunately.
Thx man i just got one with 470km on it, like brand new, how about the axles is it a drain plug for them?
Thanks!
Your welcome, thanks for watching.
Thanks for the video. Very helpful. Regarding oil, video shows 0w-40, but link shows 10w-40. same oil?
Your welcome, regarding the oil, I used 0w40 in the video mainly because the atv was going to be running in cold weather so I choose 0w40 over the 10w40 that the manual call for. I have used 0w40, 10w40 and 15w40 in the big bear and have not noticed any differences, except once it starts getting below freezing out I always switch to a 0w40. I put a link to 10w40 as it was the best deal I could find on amazon at the time. Thanks for watching!
Thanks
I know this is a old video but I have a 95 big bear and I am getting ready to change the oil in it and my middle gear is leaking and I found a stop leak product do u think it would be ok to poor a little in the middle gear with the oil
Wix best oil filter on the market available at O Reilly !! Along with Castrol 20/50 - 20/40 4 T engine oil I run it all year in my machines winters in NM are not severe great oil !!!!
Great tip! I think I'm going to try a different oil this next change.
Thank you
Your welcome
What size is the oil drain plug head size
What socket size is it again cause what i find on internet tells me 17 mm is that right or wrong on the 98 model 4×4
Thankyou
Hi, is any oil ho to clutch.. I my ATV getting hard to foot shift it feels like having something stock there when push to neutrol or shift up feels stock ot there is a step click when push hard.
Thanks
Hi all. The middle gear has the be filled until you can see the oil near the threads, (375-400 ML). The engine alone takes 2.9 liters and not 2.5L. If you fill 2.5L in the engine, your will only reach the low marking point on the dip stick. so its 2.9 liters with filter and 3.4 L with the middle gear.
How much bottles of oil do I need for a 1999 big bear 350 2wd
Does anybody know where the serial number for the rear diff is on the 1998 big bear 350 4wd? I have ordered the All Balls Racing rear diff seal and bearing kit from Partzilla and it has the wrong bearing. I sent it back and they sent another and it still has the wrong bearing. I talked to someone at All Balls Racing and he says that it is the right bearing. He thinks that the previous owner replaced the rear diff with one from different model. I don't think so because when I bought it, it was only 5-6years old so I don't think it was. I am trying to get in touch with the guy I bought it from but that was 18 years ago. I found on the Yamaha website what the serial number is for the rear diff but not where the serial number is. I can't see, I am going to try to clean it up some more and see if I can find it but any help would be appreciated.
How do you drain your fuel tank??
Do you know how to take off the oil lines that go to the oil filter cover? I can’t figure it out.
I didnt take the oil lines off so not sure, I just took the shifter off and was able to move it out of the way.
Hey I know this is an old video, but I just bought a 1990 big bear 350. Do you fill the middle drive gear up to the threads with oil? I know you said 1/2 a liter, but wanted to make sure it was full with enough oil. Thanks
mine was slightly overfilled when I put in 500ml, i think 400ml would of brought it up to the threads.
do the 2x4 models also have the second drain hole?? or is that only the 4x4 model
I believe the 2x4 has the 2nd drain hole, but I have never worked on one before so I cant be sure.
Does that have a CVT trans or the old style high low 5 speed if it’s anything after the late 80s it should be just a 5 speed no high low the 90s didn’t have those second drain plugs or anything
Mine has the high and low and is 5 speed.
Great video .... do you still have this atv?
Thanks :) and yep I still got it, I'm about to do wheel bearings on it
@@OffGridFreedom i recently bought a 2x4 1998 big bear but I need to trace out a few wires it's missing...was wondering if yours was similar
I could be wrong but I think the wiring should be similar between the 2x4 and 4x4. What wires do you think you are missing? I could take some pictures of my wiring when I go back out to the cabin.
I am trying to figure out what is wrong with my big bear ATV but I don’t know were to start
What's it doing?
Well it does not start and it has not run in a long time and I am sure I will have to replace a few things but not sure what I am supposed to look at first I will probably have to clean out the oil tank
I would do a oil change and put fresh oil in it. Drain any old gas from the tank/carb, then fill it with new gas. If it was me I would buy a can of Seafoam and add some to the gas to help clean out the carb of any gunk that was left from the old gas. I'd also replace the spark plug. After that it should fire up and run, depending on how dirty the carb is, it might require removing the carb and cleaning it out with carb cleaner.
Ok sounds good I will try that I will tell you how it turns out
Ok, good luck with it. They are great quads once it is running. I will be uploading a video on how to adjust the clutch on a big bear 350 to keep it shifting well, so once you have it running make sure to check it out.
I had a feeling this is where the filter was, it blows my mind that the shifting lever was welded on lmfao idk what to do
crazy if its welded on, makes changing a filter a little difficult. I've never tried oil changing mine without removing the shifter, its really the bottom bolt that gets in the way, maybe if its shifted all the way up in 5th you might have enough room to wiggle it out.
@@OffGridFreedom I said the same thing when I seen it, couldn't believe my eyes to be honest, but im going to try my best to wiggle it out for changing, thanks for the video though very helpful like and subscribed
Thanks for the support, let me know how it turns out, hopefully you'll be able to get it out.
Is it the same for 96?
I believe so.
Tip don’t go to O’Reilly auto parts to get wicks filter because it cost $80
ouch, I think I paid $20 on Amazon
BS !!! Ten dollar range !!!!
Thank you
You're welcome
