Default 149 oil pan

Thank you ironman and finsrwskw. It seems that ironman's link says 1 1/4" for pan # 4 that looks like mine while finsrwskw's link shows 1" bolts. The 1 1/2 " bolts I used were too long. Don't know how I came up with that bolt. I really believe the 1 1/4" bolt would be the best fit. Definitely have more threads holding. Thanks so much for your help and have a great day.
Bob

Talking 149 oil pan

George, I just re-read post # 10. I believe what you are saying is that some one (maybe me) could have used too long a bolt securing the oil pan and put a crack from the bolt hole into the oil pan. I am using a cast iron pan and used1 1/2" bolts. I believe the pan did not tighten down and when I removed engine from frame, it looked like the pan was leaking all along the sides between gasket and engine. I had used black RTV and that probably kept it from leaking worse than what it was. Does that make any sense? Do you think I may also have cracked the oil pan by using the bolts that were too long? I highly respect your opinion along with the others that have responded. I sure would hate to have to pull the engine again due to an oil pan leak. Will wait for a response before bolting up oil pan. Thanks and have a great day.
Bob

After looking at the K321 parts manual, I think it did use 3/​8-16x1-1/​2" bolts for the oil pan. Part# - X-159-4. I believe it is a Sems bolt which has an attached washer. Perhaps you used 1-1/​2" bolts without a washer and that is why they did not tighten?

Default 149 oil pan

Bill682, I used lock washers with the 1 1/2" bolts. I believe they are just a little too long. I just went down to the garage and pushed a 1" bolt through the oil pan bolt hole and there was only about 1/2" thread showing . Not nearly enough thread in my opinion. I could not find where it stated to use 1 1/2" bolts where I looked.
Ironman, I don't have a clue as to what you are saying in your last post. Perhaps you could enlighten me as my mind is not the sharpest around. Thanks to both of you for replying and have a great day.
Bob

When viewing the Kohler K321 parts manual, you need to know the engine spec number. The manual shows you how to convert the spec number to a 'variation number' which is listed under each part description. I came up with a 'variation number' of 36 from this list of spec no's.

Here is a picture of a bolt that came off a K301 with a aluminum oil pan.
Look's like it is 1 1/2"

I apologize Mr. Bob. It was just my feeble attempt at humor suggesting maybe there were missing washers.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
