I am running timing gears two metal and a centre nylon.I am thinking the oil pump cog will then run in a bath of oil keeping down the noise and helping with wear. Now will the timing cavity fill up with oil which is unable to drain away or is the oil supply not that much to fill the cavity?My opinion on the timing gears with the nylon crank gear is that they are a hand grenade with the pin pulled. The nylon has no memory so it relaxes enough to firstly let the four countersunk socket head screws come loose, then they shear off, then trash your motor. Hopefully the engineer who designed these is hangin from a tree somewhere. Naa the drugs would have killed him by now! In fact I have an SP here with this very problem. ,,,

Have 10000 miles on my bike does the shaft drive oil need to be changed or what?

Final drive assemblies on motorcycles generally cost over $1000. They tend to show signs of dirt after only 5000 miles. Having driven shaft drive motor cycles for over 30 years I usually change my 85/90 Hypoid gear oil at every second engine oil change. It is never very dirty but if taken into the sun light will show some fine metal chips (nothing to worry about). I highly recommend using synthetic Hypoid gear oil. It will cause less friction and the final drive will run at a much cooler temperature. One quart of Hypoid gear oil will change the rear end oil 3 or 4 times so it is good, cheap preventive maintenance. Simply take off the large fill cap, place a pan under the small drain bolt at the bottom of the pan,remove the drain bolt, drain the oil, put the drain bolt back in, and fill the final drive to the bottom of the larger fill hole (usually a quarter to half cup of oil), then replace the large cap being careful to only snug it tight enough to seal in the oil. If you over tighten it, it is designed to break! Be sure to check the owners manual on the exact amount of oil to use. Honda has changed the fill technique for some of the newer models. With a higher fill hole on some newer models you may be over filling the final drive, so you may have to measure the amount. Too much oil will cause waste and may cause over flow out the top vent. Happy Trails.

Looking for the oil drain plug and the transmission drain plug on a 2001 Harley Davidson XL 1200 Custom

Usually the oil drain is one the left side of the bike somewhere below the battery. Look for a hose that has a plug in it or one that connects to the frame. Harley had moved this drain so many times in the past that it's difficult to keep up with where the oil drain is located. The transmission and primary share the same oil. To drain it, find the drain plug on the bottom of the primary just below the clutch. Pour the new oil in the primary chain inspection hole of the primary.

Good Luck

For the pgo big max 50 cc they have the gear oil on thr left back side how are you supose to fill it ? Right when it goes to thr thread on the strew. I could find this answer in manuel

the bottom big bolt is the drain bolt.
the fill hole is a bolt which you take out to fill the fluid it is labeled with oil symbol or words. this is where you fill it.
there is another bolt you need to take out approx 1 1/2 inch above the botton, it should be labeled
fill or level but sometimes no marks, note: what your looking for is a bolt that dosen't attach anything, that bolt is specifically a level gauge bolt.

okay once drained, put the bottom drain bolt back in. and start filling in the top hole
until you see oil start coming out the fill/gauge hole, once you see oil start flowing out, put the bolt in and tighten, then put the top bolt in and your done.

dispose the old gear oil at your local auto parts store.
Best Regards

How to do a transmission oil chage on a 1980 sportster

There is a drain plug under the back end of the primary cover. Drain the oil and refill through the primary chain inspection hole. There is a "fill level plug" on the outer primary towards the front. Remove this plug and fill until oil runs out of the hole. Should take almost a whole quart when bike is standing straight up.

Good Luck

Overfilled gear box oil now found metalshavings

According to the header on this thread, we're talking about a Sportster with an overfilled gear box, year model unknown. On a Sportster, the primary and the transmission (gearbox) are lubricated by the same oil.

I've seen this twice. Once was caused by a carburetor that needed servicing. It had leaked fuel into the engine and when started, the excess fuel was forced into the primary making the oil level in the primary/gearbox too high. When drained, you could definately smell the gasoline in the oil and the oil was much too thin.

On the other bike, the owner had a habit of filling the oil tank to the top mark prior to riding the bike. The oil stick is marked with two marks. The lower mark is "Full Cold" and the upper mark is "Full Hot". By filling the tank to the upper mark prior to riding the bike, he was overfilling the oil tank. He just happened to have a very tight fitting oil filler cap and instead of that blowing off when the oil expanded, the oil was forced into primary past the engine's sprocket shaft seal. As long as you can see the oil in the oil tank, it's safe to run the engine until it warms up. Top the oil level off only on a warm engine.

So, you must determing where the excess oil is coming from. If the correct amount was put in the primary but more was drained out, then something isn't right. Where did the extra oil come from? It had to come from somewhere and determining where it came from is the key to solving the problem.

Also, a SMALL amount of shavings adhered to the magnet on the drain plug is not uncommon. The shavings come from the primary chain mostly. As long as it's not an excessive amount or the shaving aren't too large.

If you have any additional concerns that I've not covered here, please repost being more specific if you can.

Good Luck

What oil and how much goes in the clutch case?

does the bike use synthetics? most newer bike use a synthetic detergent 20w50..older bikes should stick with regular motorcycle oils like 10w40.
if you have a sight gauge which i believe you do, only fill it half way to 3/4 never all the way, that way you insure you dont overfill....and when filling up or measuring the bike should be upright..and models with dipsticks dont screw it in, just drop it in. If your going to change filter pour 2and 1/2 quart in let it idle for a bit then recheck it..when i first started changing my oil i was always over filling and had to drain some out. 3 quarts should be enough, but i also buy four quarts so it saves me a trip to the store for next time i need to add. Can i get a good feedback thanks!

I have just bought an old 1980 850 and it has solid drive shaft. I have no owner manual and need to know what kind of lubrication the drive shaft uses and how do I fill it. Thanks

hi,i am guessing you have a gs850g,if so the diff housing has two holes,one for draining,and one for filling,the lower of the two is for draining ,the upper of the two is for filling,to drain the diff oil simply undo the bottom of the two plugs and let the oil drain out,to refill simply replace the drain plug,undo the upper of the two plugs(this should be a relatively large one)refill with a good quality (normally 80-90w)gear oil,(the diff should hold about 400-700mls depending on model)simply fill the diff housing with oil untill it starts to dribble out of the filler hole(this is the correct lubricant level),then replace the plug,thats it ,very simple,i normally do the one in my 650 katana about every 30000km,to my knowledge there are no other lubrication points in the driveline,except the axle spline shaft which slides into the universal joint at the back of the gearbox,but this is normally fairly maintanence free as it is sealed from the environment by a fairly substantial rubber boot and shouldnt need looking at unless the rubber boot has been split or has perished,,hope this helps

Where do i put the oil back in the bike after i drain the oil? drained the oil and now do not know where to replace this oil please help!

There is a dipstick near the top level of the radiator on the right side of the bike. Just remove the dipstick and pour in the fresh oil.
To check oil level, let the bike idle for three minutes then turn it off. Now use the dipstick to read the oil level.

Please rate this solution. Thanks Eagle!
