Rear axle gaskets...final oil pan

Postby Dale Finch » Tue Dec 18, 2018 10:31 am

I came across 2 kits from Steiner Tractor Parts in my parts bins, and have no idea when I bought them. They are kit #IHS1516, and include the final oil pan gaskets. Since I am changing the gear oil in the finals, I wanted to use new gaskets, but I am concerned that these are "paper" gaskets, rather than the previously used cork, would work as well.
https://antique-tractor-parts.steinertractor.com/search?w=Farmall%20cub%20rear%20axle%20gaskets
Anyone have experience with these gaskets? The pans are in good condition, with (fairly) level gasket flanges, so I don't THINK I need the thickness of the cork to accomodate irregularities. I tend to put Indian Head Varnish on the pan side of the gasket...if I use these, would you recommend one side, both sides or no sealant with these gaskets?

Thanks.

I would only put the sealant on the final pan side of the gasket.

Actually it's your choice since the gear lub level is below the gasket.

I use RTV for gaskets on areas that do not have oil pressure. The RTV makes up for small uneven areas in the pan.
I have an excuse. CRS.

Do you think these thick paper gaskets are as good as (better than) the cork?

Dale,

I know this doesn't answer your question. I use 'Permatex the Right Stuff' for final drive (and other non-pressurized applications) pan gaskets. It has worked extremely well for me.

Oh, the repair project you sent me is still on my workbench, it has not been forgotten.

I installed those gaskets on my Cub about 18 months ago with no problems and no leaks. I use Permatex Aviation Form-A-Gasket. One thing I always do when working with a pan is to level the gasket surface. Previous owners often overtighten the bolts thereby deforming the bolt holes by dimpling them. Some support under the hole and a gentle couple of taps with a hammer usually does the trick.

Here is a good example of how to solve the dimpling problem. https://www.agriculture.com/machinery/repair-maintenance/leakproofing-engine-sheet-metal

Yep! Did the ball peen hammer trick last time I had them off... BUT, will double check that I didn't overtighten them last time!
Thanks for the input. I'll probably go ahead and use these since I have them. Worst case, the gear oil gets changed again, sooner than expected, if it leaks!

Hi,
If you fill the Cub final drives to the oil level plug hole, the oil is above the pan gasket. Below is a pic from TM Tractor of a final drive.

How to fill the final drive pans is up for discussion. I'm aware of the quantity of gear oil specified and the directions listed in the Operator's Manual
Yogie wrote:Most of us fill the final drive pans 1 inch below the top of the pan before reinstalling that way you don't need to use the fill plug on the side of the final drive housing. This also keeps the oil down below the pan gasket while it's not in use. it really doesn't take much oil for the bull gear to carry it up to the top gear and bearings and it don't have to be filled all the way to the plug. I'd ask some of the guys who have a pan off how much to add now.
Yogie's quote is one of several on how to fill the final pans during installation.

How do you keep the oil below the pan line on a LoBoy? :wink:

I think the answer is obvious: don't put any in it. :roll: :mrgreen:

I still fill the pan AFTER I have installed it. I made a super mess the first time I added the oil and THEN tried to hold it level while I got some bolts started! I think I had both feet in action, and still needed 4 hands! And trust me...that bull gear displaces a LOT of oil!! :shock:

Now I snug it up, and get my long funnel and pour it in. Guess I could measure it, but I use a drip pan and just go til it comes out the filler...which does bring it above the gasket. :?

Perfect! then it won't leak either :lol: Like a British car. How do you tell it's out of oil? It stops leaking.....
