I just bought a '94 Polaris 400 and need to know what servicing I should look at doing. The machine has 2400 miles and just has been greased. Not really knowing much about quads I think it seems to run great - cold starts fine and idles fine. I do know that the crankcase oil needs to be serviced but I do not know were the drain is and what and how much and what oil to use. (no service manual with the sell). Look forward to hearing your comments.

 

gear case
check this out its the parts breakdown for your gear box check out partsland.com for your full breakdown

29 is your drain plug and you would get the gear oil from a dealer there are some others you could use
but i cant think of them someone will chime in with that info...

 

You do not have any oil in the crankcase,you do however have oil in the counterbalancer,which has a dipstick right behind the starter pull rope.Make sure you check this as soon as possible.It holds about 70cc's of any 10w30 oil.There are 3 drainplugs under the engine,you have one for the starter housing,one for the counterbalancer,and then one for the crankcase.The tranny is separate and has a drain plug for it also.And welcome to the forums.

 

u need to take off the skid plate and the drain will be by the starter there are to drain crankcase drain and the counter balancer drain the one you wan't is the left i think and it holds a half quart or 70-75cc of 10w 30

 

One suggestion. keep it out of the water.... ive lost 2 flywheels do to water gettin in... magnets fall offa em.

Luckily polaris keeps fixin em...

 

To keep water outt of the case keep your pull handle in good and you can put some silicone around it if you dont use it.RREally need to get you a service manual these require alot attintion.
