I could use some advice on changing the oil on my friends wolverine. I borrowed the quad and told him I would change the oil for him. I don't have the manual for it and last year when I did it there were instructions, something about bleeding off the air in the system? If someone would please let me know the details, I would sure be thankful.

 

moorefun,

There is nothing to changing the oil in a wolverine. The wolverine is a wet sump engine with an external oil cooler. Warm the bike up to its normal operating temp to thin the oil. Kill the engine and let it set for about ten minutes. Now, you need only drop the plug from the bottom of the case and loosen the dipstick. The oil will run freely. Don't worry about the little bit left in the hoses, it won't be enough to make a difference. Now, unbolt the front of the oil filter cover and remove the screen filter. If dirty, rinse with gas and allow to dry. Reinstall the filter and cover. Replug the case and fill with oil to the right level on the dipstick. Here's the bleedoff your thinking of... There is a gallery bolt located on the head of the engine, facing backwards from the front of the bike. You need to loosen this bolt a little bit, and start the engine. If oil is making it to the top end, oil will begin to seep from around this bolt. When it does, shut off the engine and tighten the gallery bolt to specs. BE CAREFUL!! The gallery bolt is hollow and has holes drilled in the sides of it to allow oil to pass. IT IS EXTREMELY EASY TO SNAP OFF!!!!!! At this point you need to allow the bike to run for about ten minutes. Now shut off the bike and allow to sit for ten minutes. Check your oil and add some if needed. Repeat this cycle until you have the right amount of oil in the bike.

Thank you. That is exactly what I needed to know.

 

whats a bleed off ...why do u need to do it?

 

Warrior350ripper, if you would read all of the replies to a thread before you replied to it you would already know. He was referring to the gallery bolt.

Bleed off makes sure you have oil pumping to your top end(head), and lets out air that could compress and possibly stop oil flow.

 

I have a 2003 and the owners manual doesn't say anything about bleeding off air from the gallery bolt. I have changed my oil twice so should i do the gallery bolt thing ? Will it hurt not to do it ?

 

It won't hurt as long as you are getting oil to the topend. Because of the design of the wolverine/warrior heads, there is a possiblity of oil coming to the topend trapping air on the topside and not enough oil will make it to the top. I would be very surprised if it is not in your book to "bleed" this gallery bolt as it was in my warrior's and both wolverine's books.

I don't know if this was already stated, but be careful not to loose that spring!
