Hi folks, I've gone past 12k miles and since my belt snapped at 11.3k, I thought I'd try to see what else I could do while putting on the new OEM belt. This is on my new-to-me 2004 Swing, which might have been sitting in the dealership lot for who knows how long...

I'm thinking I should:
Change my oil
Change my plugs
Clean my K&N air filter
Change the final drive oil

I've already:
Switched to Dr. Pulley sliders

Anything else I should do? When do folks usually change their brake pads (I don't really know how to check if they're worn)?

Also... all the talk about what oil has gotten me a bit turned around. Can someone just help me figure out what weight synthetic oil to get for the oil change, what type oil for the final drive, and what size spark plugs to get (um... do they come in different sizes?)?

Thank you kindly!

cleaning your air filter this soon may not be needed since the k&n says clean every 50k, lol

Hi Hammy,

Sounds like your getting ur done!

As far as Oil, Oil Filter, Spark Plugs, and Final drive oil, you'll just need to trust your own best judgement. All the information is out there.

i've got almost 32k on my Swing Hammy and just had the 4rth rear wheel installed. Everytime the mechanic changes the tires he tells me how my brke pads are doing and they still look great according to him.

Hammy,
Change your oil... simple.... take plug out let drain... catch the spring that is behind plug. You WILL drop it if oil is hot... pay attention to how it goes. Put good oil back in .... there has been a lot of discussion here the last few days about what weight oil is recommended. I think the consensus is that 10w30 or 10w40 will work. Same oil can be used in final drive. That is one of the easiest things to do yourself for your swing. Again, just remove the drain plug, then the top plug , let the oil drain. Fill from the bottom plug to overflow, put top plug in then the bottom.
Changing the plugs is another simple, though a little more difficult thing to do. Main problem is getting to the plugs. You can replace the original with similar plugs if you need to replace them at all. Since you changed the drive belt yourself, I know you can certainly do the simple tasks you asked about. The air filter is another easy one. ALL of these projects have a
pictorial file for you to follow.

Thanks Gary... when does one actually change the actual oil filter? I just put in one 3000 miles ago. Also, is there a particular size of spark plug or are they all the same size?

Owners manual.. plugs (standard) CR8EH-9 (NGK)... OR U24FER9 (denso)

OIL FILTER: CHANGE INTERVALS 6,000 miles


Check your brand of spark plug when you pull one out. May be different. I know there are heat ranges to consider so, other brands may cross over to the NGK or DENSO.... I used the NGK.

Hope this helps.

Thanks Gary. I'm assuming the NKE is the NGK iridium or somesuch? I'll try and find where I can get a CR8EH-9 (geez, you'd hope folks just made things simple and standardized or colorized everything!)...

NGK plugs get gapped at .032-.035"

Yes, you assumed correctly.. sorry about that. Seat is too low and with my tri focals can only bend my neck so high.... Btw... when changing oil.. I just looked at the diagram and just in case you drop something.... the strainer screen goes into hole first female end up .... setting spring over that next.... O-ring next... then the plug. I also noted that you should remove filler plug when draining the oil. I do that, just forgot to mention it earlier.

Thanks! This sounds horrible but it'll be the first time I get to check out my Swing's undercarriage...

You have changed a belt out... that is major. I have not done that. I paid a guy to do mine and I watched. Probably pay the guy again the next time. OR I might trailer it to PA and watch you do it. It is so easy for some that they can take movies of it. Go figure.

I'm really not mechanically inclined at all, but after JeffR, Bill, and Tim walked me through it, it actually turned out to be really easy especially with the impact wrench. You just have to make sure you have the right tools, which I didn't but now do!

What I bought and used:
Nocord Digiwrench
1/4" ratchet and metric deep socket set
Metric hex key set with ball ends

It's really as simple as taking off some bolts, tupperware, and then the aluminum case, and then using the impact wrench to bang off the 17mm nut on the variator (now I know why they call it an impact wrench!). I think it took me about 20 minutes to get everything off, and that's because I kept slapping away mosquitoes and having stuff roll under my butt (I was sitting on the ground to do this)...

Masscoot,

Gary just used the refill method that the top mechanics use at Mercury Outboard Motors to refill the final drive on their outboard motors. Push the oil in from the bottom and let the air come out the top. Gary, I'm glad you mentioned that method.

Dennis, I wasn't sure where I learned that method. It is not in the book, I just know it worked when I did it before. You are right. I did use that method to add oil to the foot of my outboard when I had one. Masscoot... please use the squeeze bottle when you do this. Those dang oil cans usually don't fit the hole tight enough.

Not sure how you could fill the final drive from the bottom hole unless the fill nozzle was a very tight fit into the drain hole. Also, every time you had to refill the dispenser, a lot of oil would run back out. I use a pump-type oil can that must be refilled 3 times to transfer the correct amount of oil into the final drive. Seems like overkill and a really messy situation to try and fill from the drain hole rather than the top hole.

Now yall've got me all confused I thought the final drive was the one from the funeral parlor to the bone-yard!

Just what sort of squeeze bottle do you use, in my mind I see you with an old mustard or ketchup bottle and oil every where. I know there are others out there but not sure what would fit the bill. Is there something with a tube or hose you stick in the bottom hole and use kinda like an old enema bottle which would be held higher than the top hole so your not trying to push the oil uphill? Or is this something a parts house or boat shop would sell?

I use a syringe-type thing to do the final drive fill. It's called 'The MixMizer', holds about 2 oz., and is normally used to mix 2-Stroke fuel. The MixMizer also come with a 4" extension tube. I got it at Pep Boys or Auto Zone for about $5.

I pre-measure the the oil into a clean cup or jar. Then suck it up into the syringe and inject it into the final drive. Then repeat until it's full.

No reason that a ketchup/mustard squeeze bottle wouldn't work either --but you'll need an extension tube too.

After draining the oil from the final drive, and before reinstalling the drain plug, be sure to rotate the rear wheel a few times so that the final drive gears 'push' out the remaining old oil.

When I was servicing outboards I was never too successful in refilling the final drives from the bottom up. Always ended up with too much of a mess -and then had to 'top off' anyway.

I've never had a problem filling my Silverwing final drive from the top using the Mixmizer syringe. Again, rotate the rear wheel a few times so that any potential air pockets are purged before you are sure you've filled the drive.

And oh yeah, I refill the final drive when I have the belt drive cover(s) off. It's a whole lot more accessible that way.

Tim

I use a pump type oil can with a long slender spout that fits right into the top fill hole. It holds 10 oz which is what the rear drive holds. Wally World has them for under $5.

Well, My final drive filling tool is not that fancy. I just us a turkey baster $1.00 and a small piece of rubber hose and a short length of metal tube. It works OK, but that walmart, pump type oil can, sure sounds like a winner to me.

My better half frowns upon me using her kitchen utensils for other than what they were intended. Also might make the turkey be a little off flavored, so I think a trip to walley world is indicated in the near future.

Hi All, For some of you guys that don't know what a cheep, turkey baster looks like:



And NO, don't bast your turkey after you use it for final drive scooter oil installation. Just keep it out in the garage with your other scooter tools. They are only a dollar at the Dollar Store.

Mixmizer great item to have around! I use a clear ketchup bottle and a clear extension tube (I think it is 1/4") with a diagonal cut at the tip of the tube so I can insert part of the tube into the hole making a great seal.

What happens is like when you place a drinking straw in a drink and you place your finger over the end of the straw and then pull the straw out of the drink. The liquid inside the straw does not exit the bottom of the straw until you remove your finger.

With that said..

Filling the final final drive through the bottom hole until the oil starts to come out the top hole. Then you install the top threaded plug and then remove the bottom hole filler tube and install that plug. Some small amount of oil will leak out the bottom hole, but not that much.

Thank you Buddy and Dennis... I was beginning to think I was insane doing it that way. The amount of oil lost is actually less that what I lost trying to get it in the top hole.
I went to look for the squeeze bottle I used the last time I changed the oil. I did not find it. Should be somewhere, me and the wife cleaned up a little when I got the new storage building. May not even have it now. I think I bought it at the local parts store for a couple of dollars. Plan to take picture when I need a replacement. My new scoot has 640 miles on it now, so, it will be a while.

FYI
The book gives capacity of .32L (.34 US qt, 0.28 Imp qt). Honestly, it has been quite a while since I did this service. (over a year)... I don't think I had to refill the bottle any. When I do this again, I will give more details of what I do. I did this twice and just did it. Wasn't expecting to report to a forum at the time. Sorry for any confusion. You will get old and on medication some day.

One other tip some may or may not have heard of or used. When you are filling a cavity through a small hole ( like a oil crank case of a scooter or mower) and you don't have funnel small enough. Use a screw driver blade to get oil into hard to reach places. Put the blade next to the oil bottle opening and slowly pour. Oil follows... into hole. Don't try this if hole is above screwdriver.

For small cavity, take a straw from a broom or a similar slim item. Place one end in the hole at an angle, then slowly pour the fluid on the straw and watch it run into the hole If you are adding only small amount of oil, you can use soda straw... lower one end into oil, put finger on top of other end. Remove straw, put lower end into opening and remove top finger. This will let oil enter and allow the air to escape around the straw. Will take longer, but will work. For a large cavity, it is not practical, but it works like magic for small openings. I have used it many times to oil old fans with the little lube opening with spring cap.

I think I saw a movie where someone hanging from a ceiling assassinates someone by dripping poison down a thin string into the victim's glass... Um... sorry, mind wandering! I tried to find that oil can thing at Walmart but couldn't find one... nor could I find any motorcycle oil there. Silly question (I've got plenty) but DO we have to use oil that has a picture of a motorcycle on there? I mean, 10W30 is 10W30 right?
