Hello,

thanks for your help. 

I would like to know what are the fragile parts and frequent breakdowns, 
as well as the maintenance to be carried out apart from the oil changes and the specific adjustments 
of this ATV? thank

[Gwbarm]

The biggest problems I know of are wiring and electronics, the engines and transmissions are very reliable.

[Mech]

Engines and transmissions are generally very reliable. As Gw says, wiring and electronics are probably the commonest breakdown fault. The biggest maintenance issues seem to be the drive line, steering, wheel bearings  and brakes. Universal joints, wheel bearings and brake pads/shoes I have probably worked on more than everything else, including the routine inspection and adjust stuff.

[Gwbarm]

I want a Big Bear because it was manual shift and geared lower than others, seems to have more pulling power, its not as fast as others, but I really wanted one to do work, haul cars, boats, and tasks around the yard, plus go in the woods.

Thanks members for information's, now i need to get the repair manual and check my big bear for change all parts in prevention or maintenance. If you have a website for parts at a good price, I'm interested and video's maintenance

Have a nice day

🙂

I use Amazon for general maintenance things.

Anyone know if the 2002 Big Bear 400 manual the same for the Kodiak?

[Mech]

Alex #238.. The service manual has all the servicing as well the overhaul/repair information in it.

And Js, it's best to get the right manual. They probably do share a lot in common, but there will be differences too. Some kodiak are water cooled for a kick off.. Which manual do you need ?

[Mech]

I've got a manual that says it does both models, the Bb and the kodiak.

It's best to get the full model designation, like Yfm400As.. 

Look here.. https://www.partzilla.com/catalog/yamaha/atv/2004

There are always lots of differences.. Small differences but they become critical when you are working with the electricals in particular, or carbs..

[Gwbarm]

I have that manual also, that does both, but it reality there are quite a few differences, a lot of the engine parts are interchangeable and both have basically the same engine but the Kodiak is water cooled, big bear is not, the Kodiaks wiring is a little different some of it is close but the CDIs are different.

I picked up a 2002 Kodiak 400 this past weekend that hasn't ran for some time.  Was an older lady who had it and she said there was a fuel leak and they stopped riding it and didn't know how to fix it.  $250 later and its in my garage now.   Looks like new other then they had the tank cover unbolted.

Thanks,

I had that site bookmarked already with the nice exploded views of everything.

Looks like there is a manual for the 2002 Kodiak 400 in the downloads.  Going to grab that one and check it out.

Does anyone know the major differences between the Kodiak 400 and Big Bear 400 from the early 2000s?

[Gwbarm]

Good buy there JS, looks to be in good shape, for a fuel leak you may not even need a manual. Nice find!

[Gwbarm]

The Kodiak is automatic and water cooled, the Big Bear is semi automatic and oil cooled

Just waiting to hit my engagement minimum and I’ll be looking for a manual for my Yamaha machines!

[Kodiakquad]

New owner of a 1994 Yamaha Kodiak 400. I just found this site and am looking forward to learning about the 4x4. I downloaded a 2002 manual but it  looks quite a bit different from mine. Can you help with a service manual? I appreciate your help in advance, Robert 

[Mech]

Well Kodiak, is it a water or air cooled kodiak,, and does it have a five speed,  or a two speed belt drive ? And what differences have you spotted ?

[Kodiakquad]

Watercooled, two speed with reverse.  I went to partzilla and have been getting part numbers. 

[Mech]

Dang.. The manual I got was for america and canada, but it's air cooled and five speed.. Your's must be for some other market.. Or the year is wrong.  I'll have another check.

[Kodiakquad]

I'll look it over better when I get home later today. It's up in the barn and I am at work. Thanks for your help. 

[Mech]

The yanky sites all say it shouldn't be water cooled till 2000...  Same for nz and aussie.. might be a jap model or european.. First belt drive is in 2000 too for yanky models..

[Mech]

Seems yours might be a FAR.. 

[Mech]

The manual I got does euro..  All air cooled till 2000.

 

Hmmm.

[Kodiakquad]

Well, so much for a quick look! I am wrong, it is air cooled with a oil cooler and a fan. It looked like a radiator and fan. This quad is covered in mud. It really needs a serious clean up.  I have not found the model decal yet. It also is a five speed with high, low, and reverse. Sorry about that. 

[Mech]

Ha.. Phew. Had me worried for a while there.

[Mech]

And that manual has been approved and is showing on the home page, or it will be in the manuals section.

It looks like the one I downloaded was for the water cooled only model. Thanks for offering the correct model download. I looked and did not find the model tag. I need to give it a bath. Thanks for your help Mech.
