This reprint of the original CASE 400 Dealer’s Service manual contains 742 pages of specifications, pictures, how to’s, flow charts, troubleshooting charts. 1-1/2″ Thick, weighs just over 4 pounds. Covers almost every aspect of the tractor,; including engine, gas, LP & diesel, cooling system, power steering, front axle, clutch, brakes, transmission, forks,(even tells how to tighten up the shifter), differential, Eagle Hitch, PTO, almost everything. There are 16 pages on the American Bosch Pump. Even tells how to do a valve job. Believe it or not, I taught myself how to do valve jobs using a CASE Dealer’s Service Manual. I really think they are the best. The hydraulic pump and valve assembly are not covered.
