Final drive pan

[Binky Tremain]

Want to remove and clean out the final drive pans. Do you typically just use a new gasket, only use liquid gasket, or combine both? They don’t leak now, but I’m sure they will once I’ve worked on them.

the gasket surface is most likely warped so need to be pounded flat before reinstalling, use sealer on your gasket

The ones I had on the Loboy weren’t leaking because they were empty. Ultra black silicone or aviation gasket sealer are your friends.

I use a new gasket and Indian Head Shellac for a sealant.

I use black RTV instead of a gasket. There is no pressure on the gasket. The gasket/RTV is above the fill/full plug, not likely to leak.

Hi,
The fill and level plug on the Cub final drives is above the level of the oil pan and the oil pan gasket.
There is always oil being held in by the gasket, if you fill the final drive to the filler plug, which is what the Cub operator's manual says to do.

Below is a pic from Dale Finch showing the plug.
The 2nd pic, from TM Tractor, shows a final drive without the pan.

I pulled mine to clean and drain and refill. I cut gaskets out of sheet cork. I took my time, bought and used punches and didn't over tighten them. I used rrv in them but didn't do as good a job as if I just used rrv alone. The cork squashed out and ripped and they minorly leak. Next time I will just use silicone rtv maker sealer. That's what I use mostly on automotive applications and my other Yanmar tractor without leaks just rtv and following the direction for application. Not sure if the sheet cork I used was really cheap or too thin, it seemed really brittle and falling apart too easy . Not going to screw around with cork again, just use what works. In 70 years we have made advancements in gasket material. Silicone rtv is a much superior product in my opinion.
