Title: Diffrence between transmission and gear oil?
Post by: cman59 on March 27, 2014, 03:22:28 AM
Went to Autozone and was confused whenever I change my Tranny fluid... Do I buy Transmission fluid for cars to put in my 250 xciting? or the gear oil... Im confused on if there the same thing or not?

Same.... the right Viscosity is what to look for

Do you mean the hub? CVT transmissions on scooters don't use oil. For hub most use 90 wt gear oil. Or multi grade like 75W-90.

  Manual transmision has gear oil and automatic transmision has transmision fluid,.  your scooter has belt drive it is dry the gears in the back end uses gear oil 90 Wt.   oil for your engine uses 5 w 40 or 50  just the same as cars,  just different Wt. foe scooters, cars use 10 w 30 on average,.

Dedee is right, I stand corrected... ;D Manual has gear oil, Automatic has ATF....

Im more confused... So would it be ok to buy Casterol ATF to put in my scooter? do I buy automatic transmission fluid by caterol or vavoline to put in my scooter's transmission after I drain it? or should I buy the "Gear oil" to put in there?
Title: Re: Diffrence between transmission and gear oil?

Ok, let me put it this way....

In a rear wheel drive car... you have your tranny (attached to your engine) and a drive shaft to your rear differential (gear) that drives the wheels... If the tranny is manual, you use gear oil... If the car's tranny is automatic, you use ATF... The rear differential that houses the final gears use gear oil.

In a scooter, you have a CVT or continuously variable tranmission and you have a belt that is attached to a shaft with your final gears inside the gear housing.  The scooters tranny does not use any oil or fluid but the final gears use... gear oil...

Gear oil is designed to protect gears from wear. In a scooter situation, it's protecting the gears in the final drive..

This must be more of an issue than I thought. When I checked the final drive on my People 50 (well used when I got it) there was pinkish fluid in there, which immediately told me there was AFT in the final drive.  :o

I think the last motorcycles that actually used ATF were the early 80's Hondamatics that actually used a automatic transmission, not a CVT.

That said, I use ATF in the forks of several of my motorcycles when changing fork "oil".. I like it because ATF Type F is 7.5 weight. Fork oils come in 5, 10, etc.. I find 10w too heavy and 5 too light. While it's not taboo to mix fork oils to get the desired viscosity, I just go with ATF Type F and instantly get 7.5w. :)
The reason it's allowed with this situation is because forks aren't gears. It's all about forcing fluid through orifices and weight and viscosity is what's desired, not wear protection.

Just something to remember when changing fork oil someday.

All of the Hondamatic's used normal engine oil for their torque convertor and transmission. I had a new 1976 CB750 Auto.

A co-worker had one a few years ago and the tranny failed.. He said it used ATF.. I'm thinking I might know why it failed.. :)

Hey I just changed it... but I have a question... I put so much in that the fluid was running out the top? is that too much? or should I just let a little out?
Title: Re: Diffrence between transmission and gear oil?
Post by: paper on March 27, 2014, 09:25:13 PM
Normally, there will be a plug on the side of the tranny. You fill it to this level. Normally, around halfway up the side.

Title: Re: Diffrence between transmission and gear oil?
Post by: de dee on March 27, 2014, 10:23:57 PM
  some scooters have a set amount of oil in there gear box ,so read your manual,  the 300i downtown has a set amount and if you over fill it vents to the air filter , 
Title: Re: Diffrence between transmission and gear oil?
Post by: Stig / Major Tom on March 27, 2014, 10:40:45 PM
OK, this is good practice.....
Get your pan back under there.
Pull the drain plug out and dump the new gear oil out.
Put the bottom 'drain' plug back in.
Remove the top 'fill' plug and put in 3/4ths cup (smidge over 6 ounces) of your gear oil.
If it is running out the top hole - you did not let the old all drain out.
If you did drain it all and it still ran out the top hole.....I am flummoxed!
Many scoots just fill to the top 'fill' hole - most KYMCOs seem to require an exact amount when changing the gear oil....and a different amount when re-assembling the gear box. Re-assembling amount is more than the simple change amount. Obviously some little bit stays in there when you do a simple 'change' drain.
When I change my gear oil using the correct specified amount (6+ ounces, like yours) the level comes to just a little ways below the top hole threads ( I used a bent wire to reach in there to see where the level was)
Bottom line ?
If you put in 6 ounces after a good draining....let the excess come out - go have a donut and a coffee while waiting.
You should be OK then to put the fill plug back in.

Good info guys as I'm readying to do my 200 mile engine oil and gear oil change this weekend. Isn't it also a good idea to go on a 5 minute ride before changing so it warms it up and it drains better?

I just use a mini air compressor to fully drain the oil out..

Yep, maybe more like 20 mins....or just give it a 1/2 hour to drain. Don't be in a hurry.
Read the manual while you wait - try to sort out the ChingLish, or memorize the squirrely maint. schedule.
When you give up - most of the oil will be out of there.

Haven't  you now changed the printed fill amount....blowing out some of the oil that would normally remain in there?
No problem I guess as long as you catch it all and replace with a like amount.

You need only add .18 liters or 6 US ounces. Any more and you'll find gear oil in your air box and worst case a leak in the seal which will usually require replacing the seal. Your owners manual should have the specs under the maintenance section. The info I found on Kymco USA says SAE 90 and .18 liters for pre 2008 Xciting 250.

Yeah I had put so mucc in there it was leaking out from the top; so i restarted the process all over again, I think I got in 6 ounces but probably less. I would rather have less than more. don't want that stuff running in my air box and ruining things.

Here we go again.  It's time for me to replace me trans fluid / gear oil and I'm a little confused as well.  It sounds like from other members here that for Scooters, located towards the back that you insert Gear Oil and NOT Transmission Fluid.  My owner's manual says otherwise?  :o

Its oil for a manual transmision.. you can get 75w90 80w90 or straight 90. I did 75w90 cause i had it for my manual tranny. Be sure to put the exact amount.. it will require 180ml.

My Trans isn't manual it's auto. So maybe I do need trans fluid instead of gear oil?

It takes gear oil, for the final drive on a scooter. Use synthetic it lasts longer.
Title: Re: Diffrence between transmission and gear oil?
Post by: de dee on May 10, 2015, 01:10:04 AM
  think sae 90 and you dont put it in the transmision, that is dry and runs with a belt, the oil gos in the rear end,  only gears in there,
Title: Re: Diffrence between transmission and gear oil?
Post by: 0BARK4322 on May 10, 2015, 10:39:20 PM
Some manual say to fill it up to the add hole which is also the gear oil check level
Title: Re: Diffrence between transmission and gear oil?
Post by: beermak on May 10, 2015, 10:52:32 PM
The manual has a miss print there. The right way is to drain it and then fill it with the right amount. If you fill it till the bottom of the hole ull put more than 500ml when you only need 180ml.
Title: Re: Diffrence between transmission and gear oil?
Post by: 0BARK4322 on May 10, 2015, 10:59:22 PM
Well i have not got to that as yet, but question: how do you check the level of your gear oil
Title: Re: Diffrence between transmission and gear oil?
Post by: beermak on May 10, 2015, 11:24:05 PM
You cant... as far as im concerned. If theres no leak and you did put the right amount ur good and no need to check. Just change within 3000 miles.
Title: Re: Diffrence between transmission and gear oil?
Post by: 0BARK4322 on May 10, 2015, 11:39:02 PM
To check the oil the manual say remove the oil filler bolt the oil should be up to the brim of the hole. if the level is low add oil to the level of the filler bolt(hole)

Do you then have the People S200?
This video seems to say you add .180ML - period. NOT to the fill hole lip.
Also - does he put in all of that .250ML?
Anyway....https://www.youtube.com/watch?feature=player_detailpage&v=Go6y2WFnEHg#t=374 (https://www.youtube.com/watch?feature=player_detailpage&v=Go6y2WFnEHg#t=374)

No argument here i'm just saying what the manual read out and also the video is of a person who is just changing his engine/gear oil. Who is to say that 180ml does not bring it to the rim

Hey I just changed it... but I have a question... I put so much in that the fluid was running out the top? is that too much? or should I just let a little out?

You should read the service manual for your bike. On some of the Kymco scooters, they recommend to only fill the rear gearset with 180 ml of gear oil. If so, it should be stamped on the rear gear housing somewhere near the fill hole. Mine is like that, but I put 200 ml in.

I use one of those giant syringes I bought at Walmart, usually used for putting oil in 2-stroke gasoline, and put in 50 ml at a time, 4 times... the syringe only holds about 60 ml total. The good thing about using that to fill is that you can jam the little plastic hose down onto the oil bottle tip, then the syringe into the hose, pull the syringe to fill it, then put the syringe into the gear oil fill hole... no drips whatsoever. The suction in the oil bottle from pulling some of the oil out ensures that any oil in the plastic tube when you pull the syringe off the plastic tube gets sucked back into the bottle.

If you put too much in, you'll notice some of it gets pulled through the rear gearset vent hose into the air cleaner housing. Not a big deal, just clean out the air cleaner housing and fill up with a bit less gear oil next time.

As an aside, if when you drain the gear oil, you notice you're getting "glitter" (tiny metal bits) in the gear oil, that means your gears are wearing. Use a thicker gear oil. I use Royal Purple Synthetic 75W-140 with Synerlec because when the bike was new, I'd been using 75W-90 and was getting that glitter.

Once your rear gears are worn in (first couple thousand miles, most likely), you might try adding tungsten disulfide (WS2) to your gear oil. Makes things super slick and keeps everything from wearing. Use about 1.5 grams of WS2 for the gear oil. About 8.5 grams of WS2 for the engine oil.

I just put new taller gears in my rear gearset, and they're spur gears. They've got a bit of wearing-in to do yet, then I'll put WS2 in. It'll cut down on friction and wear, with the side benefit of quieting down the spur gear whine.

Post by: 0BARK4322 on May 26, 2015, 11:47:34 PM
It's amazing that I filled my super 9 gear oil to the brim years ago (that's what manual say) so I check on the filter today and no oil on it......hummmmm ...lucky I guess
