How To Service A Transmission On A 2006 Sym Scooter

Irresolute the oil in your scooter

What I'm going to draw is how to change the engine and transmission oil in a 150cc chinese scooter with a 4 stroke engine. The procedure should be pretty like on 50cc and 250cc models with 4 stroke engines. 2 stroke engines mix gas and oil and then have no engine oil to be changed.

I'd recommend changing the engine oil at to the lowest degree every 1000 miles, and the transmission oil at least every 2000 miles. Regular oil changes are the easiest and cheapest way to maximize the life of your engine. Scooters take then little oil that it should cost less than $v to practice and once yous know how to do it information technology should take y'all more than x-fifteen minutes. It's fourth dimension and coin well spent.

The first thing to practice is to warm up the engine. Run it for a few minutes and so that the oil is warm. That fashion information technology will flow easier. If you run information technology until the engine is hot, or yous change the oil after yous come back from a trip, that'south OK, only you run the risk of called-for yourself on the frazzle or with the hot oil. Be careful.

Notice some level basis and put the scooter on its eye stand. If the ground isn't level yous won't get an accurate reading of the oil level when you lot put the new oil in. To change the engine oil you'll need a wrench to remove the oil drain plug, a flat dish container with a chapters of about 1/two gallon and a funnel. Commencement remove the "dipstick" which you use to check your oil. I'd also recommend you wear rubber gloves, or at to the lowest degree on on the hand you use to remove the oil drain plug. On most scooters there is a jump which will push the plug out when you have fully unscrewed information technology and oil will pour out of the drain hole, all over your hand. It's just messy if the oil is absurd or warm, but if the oil is really hot information technology will burn down your hand. Then habiliment a glove to exist rubber.

Put the container for the used oil beneath the drain plug, loosen it with a wrench and so slowly unscrew information technology by hand. Every bit it comes lose, the spring will button it down, so exist prepared for that. You lot may drop the spring and a small wire mesh filter into the draining oil, just that's OK, you lot tin can fish them out after! Give the oil a minute or two to bleed out. Make sure the filter is clean and then put the filter, spring and drain plug dorsum. The jump sits on the plug and the filter sits on top of the spring with the mesh basket inside the spring.

Y'all'll accept to shrink the leap to start the drain plug screwing into the engine, but in one case it does start, tighten information technology up past hand to make sure information technology's not cantankerous-threaded. If it screws in hands, it'south OK. If information technology doesn't want to tighten, you've probably cross threaded information technology, and then try again. Finally tighten it up with a wrench. It should be tight, but don't overtighten it. The seal is fabricated with a rubber "O" band. You just need to tighten it enough and so that information technology doesn't vibrate lose (which would be a disaster since all your oil would drain and the engine would seize!). The recommended torque on the drain plug is 1.4 kg.m (almost 10 ft.lb)

Now you can add the new oil. It goes into the same pigsty every bit the "dipstick" fits in. You'll almost certainly need a small funnel to get oil into the filler hole without spilling it. Cheque your user manual for the recommended oil type, but on almost chinese four stroke scooters, regular ten-30W or 15-40W engine oil is used. I use Castrol GTX ten-30W. You can get a 5 quart bottle for around $12 (try WalMart) which is adept for at to the lowest degree five oil changes on a 150cc scooter. You can also use a synthetic oil alloy if you wish, though pure synthetic oil isn't ordinarily recommended. On a 150cc scooter you'll need about 0.8-0.9 liters which is just under 1qt. As you lot add the oil, check the level with the dipstick from fourth dimension to time and fill to the recommended level. When you have the right level, screw the dipstick back in and you're washed!

Changing the transmission oil is also very simple. Most scooters recommend irresolute the oil at least every 2000 miles. At the rear of the CVT on the left side of the bike there are drain and fill plugs for the transmission. Place the oil drain container under the drain plug. Now remove the filler plug first, then the bleed plug and virtually 100 to 200cc of oil will drain out. There should exist a sealing washer between the bleed plug and the transmission casing. On my scooter it'south a thin aluminum washer. Brand certain it's there and then screw the bleed plug back into the manual case. To refill the transmission, you squirt oil into the fill hole until it runs dorsum out. That'southward your level check! Employ the recommended oil, which in most cases is 80W-90 gear oil (though a few bikes may recommend using engine oil). To get information technology into the small pigsty you can use a small funnel and a brusque length of small bore rubber hose, a syringe or even something similar a turkey baster! All y'all demand is something to eject 100-200cc of oil into the hole. You may exist able to purchase the oil in a plastic bottle with a long plastic tip, which yous can use to direct squirt oil to the transmission fill pigsty. When it starts to run back out, it'southward total and you tin can replace the fill plug (note that information technology also should have a thin aluminum sealing washer).

Now run the engine for a minute or two, and then check the oil level and add more if necessary. Check for any leakage around the bleed plugs. If all looks OK, you're done for another thousand miles.
