what is the proper quantity of oil for the front diff on a 2014 kodiak 450eps..... or is it like a car...fill it until it over flows out the fill hole.
I changed the oil and now the input shaft seal is leaking.....did i overfill it by chance ????

when the oil starts weeping out is the standard. Similar to most differentials. I you think you overfilled, simple to remove the fill plug and the fluid will seek its proper level.

Fill it until it runs out.
You simply can't overfill it...but even if you did, the diff is vented. It will not build up pressure and blow out seals. It will simply blow the access oil out the vent tube. The old Grizzly 600 and older Big Bear/Kodiak's were famous for doing this after a diff oil change.

Your oil leak is more than likely just coincidence, or it simply was because you had a failing seal and the new oil is slippery enough to get past it. Either way, change your leaky seal, and get back to riding.

Might want to make sure vent is working and not blocked, my son lost several seals before we figured this out, had some crud in it.
