Part of the Kubota Repair Manuals.
This Kubota Workshop Manual covers the SM-E2B series diesel engines: the Z482-E2B, Z602-E2B, D662-E2B, D722-E2B, D782-E2B, and D902-E2B. Publication 9Y011-03173, it runs 140 pages and is the factory service manual for technicians repairing and overhauling these engines.
It is organized into three parts. General covers engine identification, precautions, the maintenance check list, and special tools. Mechanism explains engine body and cooling system construction. Servicing holds the troubleshooting charts, servicing specifications, tightening torques, and the checking, disassembling, and assembling procedures.
You get factory specifications and allowable limits for valve clearance, compression pressure, injection pressure, and fan belt tension, plus tightening torque values for general and special-use fasteners. Whether diagnosing a no-start, setting valve clearance, or torquing the cylinder head, this PDF gives the numbers and procedures Kubota specifies for the E2B diesel engines.
