First off, I didn't know if I should post this in the "Chinese Quads" or the "Kids Quads" or the "Ask an Expert" section...

My daughter rides a 2006 Kymco Mongoose 90 and I want to change the transmission oil in it.

The owner's manual states:
Recommended transmission oil classification: SAE#90

I am wondering, since they are both CVT transmissions, could I use the leftover Polaris Premium Synthetic ATV AGL Gearcase Lube from the transmission fluid change I did on my TrailBoss 330?

I can't find an exact specification on the Polaris AGL. Some say it is just ATF, but others say it is SAE 80. No body seams to know what it really is, other than that it's purple.

 

Most gear oils are 80/90 weight and that certainly would be fine when they want 80.
AGL: If it's a gearcase lube, it's fine.
It's not ATF. ATF does not have the shear strength of gear lube.
You can use ATF, I did when we raced but It's not recommended.

You got the correct section to post as Kymco's are not chinese.

 

How did you find the best way to get the transmission fluid in there? Some kind of syringe?

 

It doesn't appear to let me edit my post, so here goes.

I checked the oil when I got this and it needed to be done. While in there, the PO stated the transmission oil hadn't been done, so I figured I would do that while I was doing the oil. I used drain (A) to deplete the system. It seemed that about a half quart came out. It was actually decent looking, probably shouldn't have messed with it.

Next, I tried to find the fill hole. As you can see from the photos, my manual, while for this quad, doesn't match what I have. So I had to start looking around at other places. I found the fill hole (C) which, when (A) was open, would straight drain whatever I put in there right out the bottom. This is also about the same height as the phantom fill hole in the manual, plus or minus a MM or so, if even that. I filled up (C) until it was coming out, then let the quad sit level for a few seconds while it began slowing to a trickle. I capped it off, and drove it. All well.

A couple questions. Did I do this right? What's (B) and (D) for? Since I already changed the rear diff, I'd like to just change everything. Are they for the transmission and all I changed was the diff?

I also tried to clean out the oil filter element. I couldn't even get the thing off. I'll have to do that another day. Just fresh oil for today. Thanks in advance!

 

Anyone?

 

I have to do this to my KYMCO MXU 150, too. I lubed the chain already! : )

 

You happen to figure out what the different drain plugs are for?

 

Bump

 

Appears A is the transmission drain,B is for the engine oil.

 

Thanks for your reply! I updated the last picture with where the oil drain is, so that there is no confusion.
