My K301 has oil seeping through the oil pan. I have removed the pan and cleaned it to the point you could eat off of it. Then coated it with JB Weld in a thin layer over the whole inside of the pan. It took a couple weeks for it to start seeping again. I am not sure what the next plan should or could be. Any ideas?

Have you checked the cost and availability of a new pan. Also check ebay or our site sponsors for a used one.

The problem is funds are not available. I have a lot of supplies and that is why repair is the only way for now. If a solution can't be found I will have to save pennies for a while. In the meantime adding oil will do, especially with a snow storm due tomorrow.

If you could post a picture of the problem area would help with making a decision of which way to go with a repair. But with out seeing the damaged area I would think that it could be mig/tig welded.

Unable to get pics right now. It will be a winter of keeping a close eye on the oil. The cracks look like stress cracks around the engine mount bosses. I first coated these areas with the JB Weld. It started seeping again, so it then got a complete coating on the inside of the pan. It only seeps about a teaspoon every two weeks.

I am just looking for ideas in preparation for the repair in the spring. The tractor is for moving snow only.

The Inside?? Sounds like it's a small crack that most likely gets worse when the engine heats up/ expands... I'd try the JB again but apply it on the Outside of the pan after a THOROUGH cleaning.. Wash the pan with soap and water to remove any oily residue before applying..

Another thought that comes to mind is that new 'spray on sealant'.. I wonder if it will withstand the high engine temperatures?? Investigate that a bit.. (hey- it worked on a boat!?!?)

Are you absolutely sure it's the pan leaking and not a crankshaft or points cover or breather seal? Just some random thoughts for ya on "Hump day" :firejumper: Good Luck!

Yes I am sure it is the pan. I like the idea of the spray on sealant. I will have to look into that for temp durability. The cracks are like hairlines. It does not leak much and it also does leak while just sitting too.

I have an extra one here not sure if it is the right configuration for your engine or not; I know the JD versions don't have the "ears" for the mount bolts like this one does, the mount bolts thread directly into the pan on those; IIRC, some of the Cubs were the same way;
if yours is the "standard" style K 301, hey, kankakee isn't that far from Aurora... I've been thru there 2X in the last 2 weeks....
failing that; cast iron can be welded and/or brazed; no pressure there to retain besides gravity.

hey I'd let it go cheap!

I've used this and it seems to work well , I would give it a try if you don't have someone to weld/braze it for you , Al
