Rear End Gearcase Oil Capacity

[rockshaver 0]

Rockshaver here - I'm getting ready to change out the 80-90 gear oil in the rear end gearcase of my 3415H Mfg # 759 (1972). I have been unable to find the capacity, either online, from the original owner's manual, or from the dealer. I know I can simply keep filling until it shows full at the bottom of the fill elbow, but now my curiosity is getting the best of me: does anybody out there know what the spec capacity is, and if so do you know it just from doing it or is there actually an "official" listing of the spec somewhere.

I'll get this job done whether or not I get the answer before I start, but I know all my fellow tractor junkies out there know how it is... inquiring (obsessed) minds want to KNOW!

Yukon, thanks for the reply. This is the manual that I already have. It shows a lot of stuff, including the exploded parts drawings and maintenance procedures and schedules, but I cannot find anything that lists the capacity.

1-1/2 quarts.Only place I've seen that info listed is in the A/C 300 Series Operators Manual:

Thanks PhanDad,

I'm satisfied that this is the right answer. I was a little unsure of it at first because the AC 300 series had been manufactured by AC in their plant down south at the time my 3415 was being made in Port Washington. I was able to trace down the fact that the hydro models in both locations were in fact using the identical transmission gearcase. You undoubtedly knew this already, so... Thanks!
