Why must put gear oil in from bottom plug? By technoglide (Read 1,794 times)

Hi Folks,

I have a 2007 Kymco People 150. I was in the middle of a gear oil change when my pistol grip oil can broke. I let all the oils drain out. After some time I squeezed the premeasured recommended 180 cc into the top hole.

Why do we need to put it into the bottom? They tell you to fill to the fill hole drips, but .18L is CAST on my gearbox. As I understand, you can create slow leaks by overfilling (over-pressurizing) the gearbox.

Am I gonna be OK with pouring the oil in from the top?

You are filling with the correct amount of oil according to the service manual. However, the service manual calls the top bolt the oil filler/oil check hole. So, it looks like you should be using the top bolt to fill the transmission.

Well Damn! That's pretty sweet. I did the right thing by accident. I appreciate you showing me that online manual. I actually bought a manual on CD, which was slightly wrong in some respects. I suspect it was for older models, perhaps in other countries. The PDF titles were in Italian, but the content was a real Kymco Manual written in English.

I had oil and gear oil changed at my first service, ~700 mi. I'm at 3000 now. The crankcase oil was black as tar, down almost to the fill point. The gearbox was at 2/3 full. I guess I'll need to check every 1000 or so.

there should be 2 bolts in there,one for drain and one for refilling...yeah,pour the oil from the top inlet.,,be sure to tighten the lower bolt before doing so.

now no more sleepless in seattle,,i mean Worried in Atlanta. LOL

I always use the dribble method but now let's talk about gear oil. If any of you really want to measure an exact amount get one of those oil syringes at Wally World that's used for mixing 2T's. You might have to fill it a couple times but at the very least it makes it a helluva lot simpler to put the oil in. Rich

The beauty supplies places around me (Sally Beauty, etc) sell graduated clear ketchup bottles. the beauty shops use them as disposables for measuring different ammounts of different colors to acheive a desired shade. You can imagine the fallout from a bad color job. So these things are exact, squeezable, with good visual quality. Some have angled tips that you cut to regulate flow. These work great for some bottom loading gearboxes, as long as the filler hole is horizontal. One of my scoots is, the other isn't. Thus my original question. Check these out. They rock.

the dribble method is the one that works, fill from the top hole, I got two free syringes from CVS and that is what I use to fill it, works well
I use 80WT gear oil
