....is for the rear diff???


I have the crappiest luck. I went to change my diff fluid and when I took the front skid plate off, I saw the allen head cap screw.

Okay, no big deal. I look in the hole and it looks like it's stripped??


I'm like, WTF? I've never taken it off. I try a 3/16" allen in it and it just FLOATS...

I move up one size and it's too big. I try a 5mm allen and it goes inside with a tap of the hammer but it still won't break it loose.

Are you freakin' kidding me? So I take a torx bit and drive it in there and then unscrew it. I manage to get the screw out so I go to the rear.

WHERE THE HELL IS THE DRAIN PLUG for the rear diff??? There are 3 little holes in the frame and not a drain plug to be found.

And while I'm at it, where is the fill plug for the front diff?


Am I missing something on the rear diff and blind on the front?

Crap, I knew I should have just paid the dealer.

drivers side on the side, very bottom of diff.(access from side, not bottom) a real pain in the ass unless you have the long allens on a socket, break it loose first or your bad luck will continue with a broken allen, and on your front diff use excatly the required amount (17 oz for front) i think or it will leak out from around the bellow. hope that helps

you do have the correct fluid for the front dont you? it is diff from the rear

its the same front and rear if you are using amsoil 75w140

No, because different diffs have different needs for viscosity. Perhaps the front diff doesn’t reach as hot temps as the rear so it doesn’t need anything as thick as a 140 whereas the rear diff for example gets really hot, then it’ll need a thicker oil of say 140.

Point is, you really shouldn’t use either one opposite of what is required. The diff that gets really hot and needs thick oil when get it gets hot wont be satisfied using a 75-90 and likewise, the diff that runs cooler and needs only oil of a 90 viscosity will have too thick an oil in it if it uses 75-140.


HOWEVER, if both diffs in winter only require a thickness of 70 viscosity, then as long as it’s cool, you could use either because that’s the as thin as either oil will get.


Man, I’m going to bed... my brain is hurting tonight.

OC, you have the Can am skids too right?? If so, just so you know, the access hole in the front skid for the diff is in the wrong place. You have to take that skid off and re drill it with a 1 inch hole saw bit. Here is a thread that really goes into how to change it. You will see what I was talking about on the second page. I ran into the same problem. There is a lot of pics in there as well. Anyway, here's the link, hope it helps ya. http://www.commanderforums.org/foru....org/forums/commander-performance-modifications/1035-gear-box-oil-change-2.html

Again remember I am an Aircraft and bike mechanic. But as I understand multivis oil the rating is temperature based. So If you need 75-90 wt based upon the temperature the gearbox operates at then a 75-140 will provide the 75-90 wt required. The higher 90-140,characteristics only come into play as the temps go up.

Then why did you ask? I’m confused.

:wacko:

Yeah, I already marked the spot.

i just found that in my manual 56 i had not seen it so i called amsoil and was told to put 75w140 in front and back that it would make the visco lock work better.. Now for the kicker everybody... He explained to me that the manual was printed that way before can am started buying amsoil to put in there machines and that 75w140 is what is in all of them leaving the factory now

OK so OC is still hard at it trying to change the tranny oil now. I have to say.... as the previous owner of the manuals of Suzuki, Honda and Kawasaki machines this manual on CD from fee-bay sucks. I have been texting him photos out of the manual and man..... what is the other plug on the bottom of the engine about 3 inches from the oil drain plug? Is there a photo or schematic of the bottom of the engine anywhere to be found? WTF man. I hope to haul my machine to OC's as soon as I can and I can shoot the OC how to remove the factory skids what is needed are there rivets etc, doing the diffs and the tranny etc. This is WAY to hard. One plus of the Teryx is it is WAY EASY to maintain the oils compared to the Commander. FOR SURE! SHIT man!!

Is the rear differential solid? I stated that wrong, if it is a differential, it would not be solid. If the rear end is solid with only a ring and pinion, no spiders, then a heavier viscosity oil would be okay. If it is cold then you may possibly need a need a lighter oil in front to make the Visco-loc work. The front may work better with a higher viscosity oil hot weather. I know that a multi-v oil is supposed to cover a wide range of temps, but GL 140 will get thin when it is hot.
I do not think there are two different oils in the front end, as from photos I have seen, there seems to be only one sump. Check before the fires start flaming. I am new here, and not the sharpest knife in the drawer, by all accounts.
Most heavy construction machines use a 50W non-detergent oil plus additives. Nothing concrete on my part, just guessing. My machine has not been picked up yet, even though it was to be in yesterday. I have not seen a manual yet, only parts of pages that have been on posts. Will keep riding the Kubota for a few more days.

No, I couldn't... it wasn't available when I purchased my Commander. Look at the freakin' date. They were on national backorder at the time.

And not to mention (had you read even the first page of the thread) that Can Am screwed up on didn't put the drain plug hole in the skids in the proper location therefore completely hiding the access hole.
