All 3 of my 1x6 1x7 tractors have studs on the fuel tank mounts... in total 5 studs, 3 for the tank mounts and 2 for the heat shields.

If the rain stops for long enough tomorrow I'll go take apart the top of my k321 in my 147 and get some pictures of my setup for you.

Pictures, as promised. Sure hope these help because I dont really want to go back out in the cold and rain to do this again.

So this is the setup of my 147. 5 head studs and 4 head bolts. 3 head studs to hold the gas tank mount and 2 studs to hold the heat shield. I realized as I took these photos that I never bolted the gas tank mount down due to needing to pull it off again, as you can see by the 3 studs without nuts on them.

With the heat shield removed... I did not pull the tank off, hope that doesn't hinder anything

Here's a head stud pulled, with all its spacers. As you can see, first is the 3/4" tall spacer, then a large flat washer, and then the nut. The 2nd nut is for holding the heat shield/fuel tank mount.

This is a head bolt. No spacer is used, just the large flat washer.

At this point I discovered something strange. I went and grabbed my probably junk head that was overheated and warped, and I noticed something. This head was on an engine that had all head bolts, no studs. The places where you put the bolts are much taller on it than the head on my 147's k321. It essentially has those 3/4" spacers made right into it. Since you say you do have studs, I assume you don't have this style head, but still found this interesting.

Although they don't fit down into my junk head, this does a pretty decent job showing how everything mounts in order.

And lastly, just to show that I indeed have the same exact head bolt/stud numbers on my other 2 cubs, here's the 106:

And the 107:

I really hope this shows you what you were looking for and gives you the information you need.

Well I suppose any combination would work ,as long as you got the head securely fastened, the right length bolts/studs ,the tin in the right spots and enough spacers to take up the voids ! I do know I have to remove the gas tank to retorque the head bolts !

107 thank you for all those pics. Its too dark to take a pic tonite but I will get one here tomorrow evening. Think I got mine figured out. Missing one spacer and I BELIEVE the head bolt nearest the oil fill tube is a longer bolt as it holds the tin down.

The head gasket soaking used to be the normal procedure, however since the manuals were printed 50 or so years ago, new designs of head gaskets have been made that are a lot better than the old old ones, and they do not require soaking in water.

Head bolt torque is 30 ft lbs, start at 10 or 15 and work your way up to 30 in increments of 5. Be sure to do this following the correct tightening pattern, which can be found in the service manual.

I do not know the specific specs on oil pan bolt torque.

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.
