Default head decarboning? Nesscary with MMO?
Guys,

Per the net-wisdom, I have been running MMO in my 1650- and it has been running better. With an unknown service history(as if there is ever a known history on a IH CC tractor?), would you still pull the head and clean it?

I have removed the schroud and cleaned the fins.

Michael

If it was my tractor I would, the Kohler manual states that every 500 hours the head should be removed and cleaned, headgasket replaced, and inspected for wear and damage. That way you know that it has been done and won't have to worry about it for the next 10 years (or 500 hours, whatever comes first) . Cleaning the head, checking trueness, and changing the headgasket only takes and hour or so.

You can lightly mist some water in the intake while the engine is running about half throttle. The water will turn to steam when it hits the hot combustion chamber and the steam will blow the carbon out. Just don't mist enough to stall the engine.

If it was my tractor and it hasn't been using excessive oil, I probably wouldn't touch the head as long as the tractor ran well.

WEll,

I pulled it off- bolts didn't seem that tight. NOT good- First time I changed the oil there was some metal, now I know running a clogged airfilter will washout the rings and score the cylinder wall.
THe scores have polished so it's wavy around 2/3 - 1/2 the cylinder.

Aluminum timing pin. Sounds like I have some parts to buy.

The bolts are only torqued to 25-30 ft lbs by the manual, so they aren't really that tight anyway. Keep us updated on your engine!

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.
