TR-800 JOHN DEERE CLUTCH

The TR-800 clutch has rollers mounted to the flyweights. The ramps are fixed to the movable sheave. Flyweight mas can be altered without affecting the shifting profile.
   This is a new clutch which was introduced to consumers for the first time on the 1982 model John Deere Liquifire, which had logged thousands of miles in the field before it was ever installed in a consumer model.  The TR-800 clutch testing program began in earnest during the 1981-82 winter season.
   Some of the early proto-type John Deere TR-800 clutches were plagued with an overheating problem which caused blown belts, however the problem was solved by John Deere.  First by running it open faced like Comet, but the results were unsatisfactory.
To solve the problem, what they came up with was a combination of a rib with a hole behind it that would move the air like a fan and thereby cooling the moving sheave and the belt.  The cooling veins actually created a low pressure area.

CHAPARRAL THE COMPANY

January 1974 - Chaparral was a division of Armco Recreational Products, Inc., and was located at 5995 N. Washington St., Denver, Colorado.  Armco Recreational Products, in turn, was a division of Armco Steel Corporation of Middletown, Ohio.  Another division of Armco Recreational Products was Red Dale Coach, manufacturer of  live-in recreational vehicles headquartered in Longmont, Colorado.  Other products within the Chaparral Division included sport cycles, bicycles, barbecue gas grills and government defense products.
Chaparral, founded in 1967, was purchased by Armco in 1969.  For the first two or three years, Chaparral  was a highly independent division.  In 1972, however, Armco began to play a more active management role, highlighted by the appointment of a long time Armco executive, to the presidency of Chaparral.

NATURALS VS. SYNTHETICS SNOWMOBILE OIL

September 1988 - There has been a gradual rise in the use of synthetic oils.  Although synthetics are anywhere from two to five times as costly as natural petroleum based oils , they do offer some distinct advantages.
Because petroleum based lubes are refined from crude oil, they can sometimes be just that.  When oil is refined, it is heated and separated into different factions.  The lightest and cleanest factions are used to make gasoline and kerosene.  The oils collected for lubrication purposes are those that are heavier, have a higher thermal point and have settled near the bottom of the refining tower.  The same qualities that give the oil a higher viscosity (sticking ability) and resistance to thermal breakdown, are responsible for a certain amlount of carbon buildup.
Synthetics, on the other hand, are man made lubricants that can be custom tailored to specific applications.  With synthetics, a chemist is not confined to what nature has provided and therefore can produce a lubricant that has a high film strength and burns cleanly.  With petroleum based oils, the higher the film strength, the dirtier the combustion,
