This is my first post but I've been watching for a while.

I just purchased a 1998 300FW and have a few questions:

1. Is the clutch a wet or dry clutch? Bottom line is do I need to use an engine oil designed for wet clutches?

2. The Owners manual said to use 10w40 oil in the front differental. A local shop uses 80-90 oil in the front, middle, and rear. Is there a problem with this?

3. What are some areas I need to take a look at on this atv? I cranks and runs fine.

Thanks

You do need an oil made for wet clutches.

Just change all the oils, fuel and air filter, spray wd-40 on all the rubber like the CV boots and tie rod ends and check the clutch and brake adjustments. Then, ride it. :)

As for the oil in the diffs, I'm not sure. The differentials typically use 80-90w, but if the book says 10w-40 then that's what I would use. I would guess there is some confusion about what we're talking about, so just be sure you know what it is the book says about which part.

According to my repair manual, the front and rear differential uses hypoid gear oil, SAE 80W. This is from a 1995-2000 Honda Fourtrax 300 4X4 repair manual. It is the Honda brand manual. It says to use Honda GN4 motor oil (10W-40) in the front gear case(transfer case), but I think a lot of people use the 80W gear oil in it and it seems work fine. Welcome to the forums.

there is a "check bolt" on the front of the gearcase that u fill till it starts trickling out. it has an alluminum sealing washer on it so dont loose it when u remove the bolt. same with all the drain bolts on the unit.
