149 oil pan gasket

[Mr Bob]

Thanks for all the advise. I will take the pan back off and start over. Don't know why it leaked. Used only the gasket the first time. No sealer. It leaked around gasket on one side. When I rebuilt the engine I trued the cast iron oil pan with glass and sand paper. Looked pretty good after that. I really don't want to pull that engine again. I have another oil pan gasket. Bought 2 the last time. Never heard of a thread chaser. Hope the threads are ok. Will be next week before I can work on it. Thanks once again and have a great day.

You don't want that crap floating around inside the engine, any engine for that matter.
It will find its way everywhere you don't want it.
Oil coolers , radiators, oil pumps, breathers, what have you.
Plus, the next time you go to use it 1/2 of it is set up in the tube and you may as well pitch what's left. The brush on stuff last for years on the shelf.

When used properly.. There is not a problem with it

Key to this like anything else that is tedious is to take your time. As far as other posts here go. I have been a full time heavy equipment mechanic and shop owner for over 30 years. I use RTV Black, blue, and orange on almost a daily basis. It works great and holds up well. Im not saying that other products wont perform as well as this. Its just what I prefer to use.


Here is a picture of some thread restorers "chasers" notice the tip does not come to a point. This allows you to get to the bottom of the threads without the tool bottoming out. You can most likely get just one "the size you need" at a hardware store. A cheap set can be found online. I would not buy an expensive set if your not using them very often

Last I knew, Oreillys rented a set of these. You cant beat free!

Could some one verify that the oil pan bolts are 1 1/2" length. I put them in block with out oil pan and the distance left on bolt seemed too long to tighten pan down. Looked like they would bottom out before tightening oil pan. Thanks in advance and have a great day.

Parts lookup list them as 1" I think those longer bolts you have are for mounting the engine to the tractor frame.

1" bolts are for mounting to the frame.
The pan bolts are indented head and also 1" long
The parts book tells you all this guys!

[Mr Bob]

finsruskw, Where might one find a parts book for the Kohler 321A? I have looked in the Technical library- Tractors but could not find what I was looking for. Help appreciated. Have a great day.

Has all the tractors broken down by sections.
Click on the 2nd cub cadet, not the newer MTD version on top.

I also have the hard paper copies as well
