How do you change oil in transfer case and when should it be done?when you change the motor oil is that combined on this bike with the transfer case?

It could be any number of things..First off,just like a car,the oil settles when the bike has not been ridden awhile..Worst case scenario it could be your clutch but without knowing what kind of bike it is or your riding habits..I.E. Gunning it..Not letting it warm up before you take off like a bat out of he'll..I mean how does it ride? Are you able to shift it smoothly? Is the shifting rough and erratic? I want to hear from you again on this cause it may be simple as changing the oil..Or not..Let's hope for the best..

you can use 10w30 or 20w50 motor oil. in any bike I`ve owned from a 72 Honda 350 to a 88 Goldwing 1500 and serviced bikes into 2004 I`ve used 20w50 Castrol motor oil without any problems at all. the amount your bike will need is marked on the case where you put the oil in. I think its about 2-2.5 quarts with an oil filter change.

They change it after a certain thousand miles. Read the manufacturers recommendation. It is a good point to have it changed every 30000 miles.

How to change the engine oil. You will need to remove lower part of fairing to access under the engine. There you will find a drain bolt to undo. A large bolt located on the underside of the engine, usualy with an aluminium washer, or O ring. Undo the bolt and catch the oil in a suitable container. This should be done when the engine is warm, as the oil will flow out better. When empty, replace the sump bolt, preferebly with a new washer so it wont leak.
Replace the correct amount of oil back into the bike.
On top of the transfer case will be a plug you can undo by hand, the oil filler, mabey this has a dip stick on it for level. Most Kawasaki also had a site glass for the oil level, on the lowe , side of the engine.

You left your petcock on, the fuel bowls over filled and the gas went into your crankcase

DON'T START THE BIKE WITH GAS IN THE CRANKCASE YOU WILL BLOW THE MOTOR.

Empty the gas, put in fresh oil, run engine, then change oil and filter again and you are done.

Somewhere on the bottom or bottom outside edge of the gearbox is a drain plug. Drain the oil and put the plug back in place. Somewhere on the top of the gearbox casing, including the left and right outer case covers, you will find a dipstick for checking the oil level. Fill via the dipstick hole. Some bikes don't have an actual dipstick but only have a top plug. Normally you will find it near the kick starter lever. When no dipstick is provided, they expect you to drain the old oil and then re-fill with the amount of oil specified for the bike. Use 10w40 motor oil. NEVER use synthetic oils. They can screw up the clutch.

most harleys the crank drain is under the skid plate at bottom of bike, so oil changes are done via oil tank drain. always change the filter.

it could start without oil..... but the amount of damage you would likely do to it makes it very unwise. if all the oil leaked out there was oil in it when it was started before. if i'm not mistaken that case is aluminum. if you can find someone that does tig welding (i think it's tig for aluminum).... they could probably weld that crack without taking the motor apart..... just a thought.

please take a moment to rate this solution.. thanks

there is really no need to change the transfer case oil other than not having anything else to do and it is very hard to get it out.. putting it in on the other hand .. you will have a recessed bolt in the top on the transfer case it looks like a 1/2 inch drive extension will go in.. back that out and put your finger down in the hole if you can't touch fluid it is low. go to local auto parts and ask for 90 weight transfer case oil.. if you tell them what type vehicle they will give you the right oil. probably need spout to get it in the hole.. secure nut back on and your done.. good luck ray
