Operating I nstructions for Cockshutt "30" Tractor

BREAT HE R CAP - This cap acts as a filter to clean the air which surges into and out of an engine when it is operating. To remove dust and dirt from the air drawn in on the inward surge, the screen must be kept clean and covered with oil. It should be inspected and if dirt is present, the cap should be washed in gasoline, then dipped in engine oil, excess oil shaken off, and the cap put in place again.
CHASSIS LUBRICATION At least once a year, or every 1000 hours, drain transmission compartments by removing the three plugs, 21 and 22, on the lubrication chart. Preferably the draining should be done whi le the tractor is warm. The t ransmission will require 4%, Imperial gallons (5 U.S. gallons) to fill and the pulley hous ing I %, Imperial gallons (2 U.S. gallons). After filling the transmission do not use t he cree per with the shift in the low speed (lever towards the rear) until the tractor has been operated for about one hour or so, asthis chamber is filled from the transmission by splash. If th e tractor is operated at very low temperature the pulley housing and transmission lubri cant may be thinned with one half gallon of kerosene, but before using in warm weather th is thinned mixture MUST be drained and replaced by new oil. QUALITY OF LUBRI CANT - Use a good grade of mineral oil made by a reputable manufact ur er as the best assurance of trouble-free service. SAE 90 transmission lubr icant can be used both winter and summer. FRO NT WHEEL BEARINGS - To provide satisfactory lubrication to the front wheel bearings remove wheels, clean and repack with wheel bearing grease periodically. PRESSURE GUN LUBRICATION - Use a good quality grease, not one that will thin out under load and moderate temperatures. Keep the grease and the gun clean clean each fitting before use and force enough lubricant into fitting to insure a fresh supply to the wearing surfaces.
