Quietline
Hello gentlemen,
I have a 1974 IH Quietline that has a blown head gasket. I have ordered the replacement but my question is. With these original 10hp Kohler engines do I need to tourque to specs when putting the head back on? Or can I just tourque down to tight? Any help is appreciated. Thank you

Yes, definitely do torque the head bolts to spec. Spec is in the range of 30-35 ft-lbs, 30 will do just fine. Be sure to look at the tractor service manual and find the head bolt torque sequence, and follow it!
Before you put it all back together, I have a recommendation. Because you blew the gasket, you may have warped the head or it was already warped and caused the gasket to blow. The way to remedy this is to take a piece of 220 grit sandpaper, and set it on a flat glass plate, then sand the surface of the head down until it is flat, making sure to keep a random sanding pattern so it works evenly. With the head on a flat surface, you should not be able to stick a .003" feeler gauge under the head in any area. Once back together, run the engine for a couple hours and then re-torque the bolts to 30 ft-lbs again. When you replace the head gasket, it compresses and the head bolts will loosen slightly. Re-torquing them will remedy this.

Thank you all for the help. Any idea where I can find the specs at for the bolt pattern when I torque it back down? This is the orginal Kohler 10hp.

-Sanded head flat on a piece of glass using Matt G's advice. -Decarboned head/top of block -Checked block deck for flatness with a straight edge. -Oiled cylinder wall -New gasket with copper coate -New head bolts - a drop of oil before install. -Torque specs are 15-20 FT LBS for this head, started with 15. -Ran for 20-30 min, made it work a small bit (driving it around, taking off in third gear with my fat butt on the seat) -After the engine cooled off (like next day) tightened the head bolts to 20FT LBS in the proper order 2-3 times making sure they were tightened properly.

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.
