Rear axle lubrication

Postby cub78? » Mon Nov 06, 2017 2:50 pm

How often should the fluid be changed. Only cut grass with the tractor. Actually only used about 150 hours per year. The filler plugs are under the quick hitch and a real chore for an old man. Thanks for any info.

If any of the tractors I have worked on are any example, probably about every 35 years. In all honesty, I don't think this needs to be done very often. Maybe every 5 years or so.

EDIT: The manual says the gear oil in the final drives should be changed annually or every 1000 hours. I got my Cub 4 years ago and have never changed the lube in the finals. It hasn't detonated yet, but I should probably go ahead and do it. I know for a fact that the finals on my B haven't had the gear oil replaced in at least 12 years.

Welcome to the forum. A bit more info needed to directly answer your question however, the rear axles are lubricated via the transmission and the final drive assemblies are lubricated from the reservoirs attached to the bottom of each assembly. Detailed lubrication guide and information is available in the manuals section accessed via the Quick Links tab at the top left corner of this page. You and view and download the info after a couple more posts. A good place to learn a lot about Cub Tractors is attending a CUBFEST. There are several in your area.

Checked every 5 years or so sounds about right...

Well.... checked and changed are two different things. I check the fluid level annually.

You are way ahead of the game.....i would recommed never change it under the following rationale....automotive rear axles with hypoid gears recommend 30000 to 100000 mile intervals. Cub finals are spur gear with far less oil shear and much lower contact stresses. 100000 miles on a cub is 14000 hours give or take. Its a good guess thats only been done once or twice in 250000 tractors. Full is good....run with it....

Hi,
You didn't say what year Cub you have, your name has 78 in it, so maybe the Cub is a 1978.
Below is an owner's manual for the newer Cubs, mid 1975 through 1979. It has lots of info about operation, maintenance, and lubrication.

The newer Fast Hitches had a hole in the bracket for checking the left final drive oil. :)

I would think the answer here would not be so much a question of fluid breakdown as of contamination. If you suspect the oil has been contaminated with water it’s time to change.

In my trucks I changed the differential oil, tranny oil and transfer case oil one a year, I pack the front axle with grease and new seals. My tractors get a oil change the minute I buy them.
Maintenance is the key to a long lasting relationship with no big repairs. Pay me now or pay more later.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.
